With the prefix "bio"

If the wastewater treatment must occur in the septic tank, the post-treatment - in various designs and constructions: on the leach field, in soil (sand) filter, biological filter and aeration. They all provide aerobic (with oxygen access) after treatment of wastewater after septic tank. If the first two are the facilities, where waste treatment is carried out in natural conditions, biofilters and aeration - this design, based on the method of treatment in a simulated biological environment. In some cases, however, should be used with the installation of the biofilter or aeration tank? The general answer - when you can not apply the soil after treatment. For example, if a part of high water, cramped conditions (there is no possibility to arrange a leach field) or if, under the requirements of the local authority Rospotrebnadzor banned soil filtration in order to protect groundwater from contamination. And finally, if you aim throughout to keep pace with progress, because today the installation of biological treatment plants are considered the best technical solution in this area. Although the device and the biofilter, aeration tank and apply to systems of biological wastewater treatment, yet they are structurally different from each other, and the degree of purification in them are different. Do not forget that the biofilter - this is not a standalone unit. In front of him must be installed septic tank (or septic camera, if it is a monoblock) for wastewater treatment. Only after passing through the septic tank effluent enter the biofilter, where aerobic conditions are filtered through the feed material that is covered with biofilm formed by colonies of microorganisms. Biofilter, as a rule, consists of the following elements: the filter load, the water distribution devices, and aeration duct (after it receives the necessary air for the oxidation process). As the boot manufacturing companies use light porous materials: concrete block, shungizit, puzolan, coke, plates of stone wool, nylon cords. Once in the biofilter, waste water distributed on the surface of the load and by filtering, draining to the bottom of the tank. Then they should stand, after which purified water is diverted into a drainage ditch or on the soil after treatment. What are advantages of biofilters? First of all, ease of maintenance and the full energy independence. To create aerobic conditions here do not need pumps or compressors - air in the chamber bioiltra gets through aeration pipe. As for the disadvantages of devices, then one of them is that the filter material should be periodically replaced (expanded clay, stone wool) or washed (puzolan, nylon thread), so you must strictly observe the rules of operation of equipment. But there is a drawback: after most of biofilters is required post-treatment soil, thus had to use construction of an underground filter. Nevertheless, the installation of a biofilter used widely because they are largely purified waste water, thereby making it easier to work on their final cleaning and prolonging the life of the whole system. And yet the most effective to date are facilities that are undergoing a complete cleaning cycle after which the wastewater can be discharged to the terrain, the drainage ditch or roadside ditch. The degree of purification in them is 96-98%. Typically, these units consist of several chambers, united in a single package or separate modules, which are collected in a single complex. Drains in them are a number of processing steps, but the protagonist of such systems - aeration. There, as in the biofilter, waste water is treated in aerobic conditions, but the bacteria that are here, others, and, besides, cleaning occurs with forced air supply. In the aeration tank is slowly moving mixture of sludge and waste liquids. To maintain the sludge in suspension and the mixture's saturation of oxygen required for respiration of microorganisms, activated sludge and waste liquid is constantly stirred by pumping compressed air. It is served by a pump or a compressor (power 20 W 01.20), which is usually placed in a residential house and connect with the installation of a hose. Some systems use a combination of aeration tanks and biological filters, which greatly improves the quality of wastewater treatment. Undoubtedly, the main advantage of the deep biological treatment plants is the high degree of wastewater treatment that allows you to dump the treated water to the relief (in this case it is important to ensure a steady flow of water, so it would not freeze in winter, turning part of the plot in the rink). However, they also have drawbacks. For most systems on the Russian market requires the following conditions: constant concentration of contaminants (ie, unchanging composition of effluent), the stability of the volume of waste water, uninterrupted power supply. If two or three weeks, the system does not operate, the bacteria are killed. For some installations have to buy them, adding to the device and wait for the microorganisms begin active life. Installation using biofilters equipment, which uses artificial scrubbing bio-filters, presented at the Russian market, both foreign and domestic companies: Green Rock Green Rock 05 and 1 0 S by GREEN ROCK (Finland), Purflo CEE from PURFLO (France - Russian), "Cedar" from "SBM-GROUP", "Breeze 1SE" and "Breeze-2SE" from "ELGAD POLYMER", "Aspen" from the Research Institute of SANITARY ENGINEERING (all - Russia) and others Biofiltration of waste water treatment plants of the company GREEN ROCK is using plates or cartridges from stone wool brand Green Rock. This fiber is made from molten rock, which, being a natural material, easily disposed of by composting. Filter treatment system able to hold solid particles as small as 1.6 microns. During processing, water flows through the conditioned culture medium, enriched with oxygen from separate ducts. Bacterial colonies formed on the surface of the loading material (PVC-washers), process remaining in the effluent solids, splitting them into water and carbon dioxide. Performance of treatment plants GREEN ROCK - from 1 to 60 m3/day. For a country house with the number of living 4-5 people fit the model Green Rock Green Rock 05 and 10 S. Purified water in them can be reset to the relief. For removing phosphorus from wastewater is applied precipitating chemical AquaStone (from Finland). Installation Green Rock is completely non-volatile, their body is made of polyethylene. The devices can be installed in existing systems (to use the existing septic tank, but after it installed biofilter Green Rock). Biological filter Purflo CEE is the capacity of high density polyethylene, which drains after the septic tank are subject to advanced treatment to the level of technical water (95-97%), then reset to relief. Biofilter consists of a diffuser connected to the inlet (through it sinks to get inside and are evenly distributed over the surface of the filter) filter loading puzolan (singular volcanic rock); team pipes in the bottom of the biofilter that is connected to the outlet, the aeration tube. In the model Purflo CEE aeration is totally independent from the issue. Air enters the reservoir through two pipelines at the entrance and exit of the biofilter with the opposite side of the tank. Wastewater treatment plant "Cedar" is a plastic container, separated into four functional camera. After the deposition of solids in the first chamber and in-depth clarification of effluent in the second they get into a third chamber, where there is a removable flushing biofilter. Fourth camera-clarifier can be used as pumping wells (installed any sump pump with a float in case you need to raise the level of abstraction of purified water). In the installation "Breeze" process of sewage treatment occurs in two stages: first the mechanical cleaning and then - biological doochi-stka through life being in the aerobic reactor ("breathing") bacteria that are specifically charged to him. After the water passes biofiltration soil after treatment in the field of filtration, then it can be drained into the ground or gutter. Station 1SE Breeze "and" Breeze-2SE "are intended for country houses with the number of residents from 5 to 10 people. Necessary maintenance is the annual removal of sediment. Complex "Aspen" is made of reinforced concrete in the factory in compliance with the stringent technological requirements. The system consists of a two-chamber metatenka (uses special bacteria) and trickle biofilter, where the mechanical and biological treatment in three steps. Then the water goes into the soil after treatment in filter trenches or wells. Once in three years, setting clear of accumulated sediment through sewer machine. System of deep biological treatment system of deep biological treatment - this treatment facilities, which operate aerobic bacteria. Necessary concentration of oxygen in them is supported by feeding from the compressor (via aerators) compressed air. Such plants are characterized by large oxidative power and allow after treatment of discharged waste water on the landscape. Installations range TopolWater were developed in the Czech Republic on the basis of experience designing and exploitation of large industrial aeration tanks. In Russia, the products from this brand produces LLC DYSENKO KO. The system has a number of modifications and their ability to adapt to specific user requirements. Scope of products is extremely wide: from a detached cottage (model TW-5, TW-8, TW-10) to a village (TW-150). Installation is a single body made of polypropylene panels with a foamed inner layer. The tank is divided into a number of technological compartments, perform the following functions: accumulation and equalization of wastewater, aeration, biological treatment using activated sludge, the accumulation of surplus activated sludge, sedimentation of clean water. Unbundling occurs depending on the position of a float switch water level in the storage tank. When firing a three-way solenoid valve redistributed air flow to the functioning of technological elements of the system clean. The plant can live without drain up to three months (through automatic maintenance of the level of sludge in the aeration tank), and the user went on vacation or a long business trip, returns to the printer operation. This same feature allows you to use the system in a mode of non-uniform flow (the so-called "cottage" type of operation). When turning off the electricity TopolWater works as a normal septic system. Removal of sludge produced regular pump-airlift. System from "BIOTAL" (Russia), capacity from 1 to 500 m3/day. different dimensions, the number of airlift, aerators, and compressors, and therefore suitable for a country house, and for the cottage community. Installation of a container made of polypropylene cylindrical shape with three successively connected to each other SBR-reactors (reactors alternating action.) The system is fully automated: it requires constant maintenance, as well as additional supplies. For a small admission or no inflow of sewage plant will automatically go in the first (1 hour), second (24 hours) and third (48 hours), cost-effective modes, which together with reduced power consumption (up to 3-4 times) substantially prolongs the life of the equipment. When volley discharges (discharge large quantities of water, for example, from the bath) the device switches to the forced operation that protects the system from the removal of raw sewage. At work station is not affected by discharge of waste water with chlorine and various detergents. When the power cut, it operates as an ordinary septic tank, and after resumption of power supply returns to normal, recovering without additional measures. Therefore Biotal can be used in homes with periodic residence. The technology is designed so that the cleaning process does not occur methane and sulfur dioxide, and therefore there is no odor at all stages. To get rid of sewage sludge did not want the machine because it is removed from the filter bags as they are filled with a special device. ZAO TD "ENGINEERING EQUIPMENT (Russia) makes installation" Tver "steel with additions of alloying elements (nickel and chromium) and polypropylene. Housing plastic products are equipped with steel frame, which prevents them from strain, so the installation is carried out without concreting. Inside the equipment is divided into six sections: the septic tank, an anaerobic bioreactor, aeration with sludge and porous load, secondary clarifier, aerobic bioreactor with an attachment of artificial seaweed, dolomite loading and secondary clarifier. The range includes a plant with a capacity from 1 to 400 m3/day. At various unfavorable factors: power failures, prolonged periods of time in the inflow of wastewater, the peak of inputs - the work of the system remains stable. The degree of wastewater treatment - 97-99%. Installation "Tver" distinguishes ease of installation and maintenance. Bioseptiki "Yalma" Polypropylene Company METZELER PLASTICS (Germany) produces the Russian company "Albatros". They refer to the combined facilities that use as a biological wastewater treatment with activated sludge (aeration) and clean with a biofilm attached to an artificial load (biofilters). Installation is a cylindrical container with technological hatches, divided by internal partitions into a septic tank, an anaerobic bioreactor, aeration 1 st-stage biofilter, aeration 2-nd stage, a secondary clarifier. Aerators in the aeration tank 1 st and 2 nd stage, as well as airlift, located in the secondary sedimentation tank, pipes connected to the wiring system of the air from the compressor. The model number "Yalma" includes installation "5P", "8P", "16M", "40M", designed for service from 5 to 40 people. Devices intended for private houses, have a length of 2-3 m and a diameter of 1,45 m. Treatment Facilities "leader" made by the Russian firm "LOKAS" in two versions: steel, protected by a multilayer corrosion-resistant coating, and HDPE (High Density Polyethylene) 6 mm thick. Purification unit is divided by internal partitions in the following capacity: the septic tank, bioreactor, aeration 1-th stage, a secondary clarifier, aeration tank 2-nd stage, tertiary clarifier. To operate the installation does not require additional supplements. The main technological feature WWTF "Leader" is a significant increase in the receiving chamber, a septic tank that allows for more efficient lighting to produce runoff and significantly less likely to pump out accumulated sediment. The system is tolerant to power failures, lengthy interruptions in the flow of wastewater. Lineup of products designed for service from 4 to 30 residents. When installing the equipment does not require concrete foundations. The company "HBP-BIO" (a subsidiary of concern "National water resources") offers installation "FPC", which are produced in two variants: plastic and metal with a corrosion-resistant coating. The devices include a primary sedimentation tank, two aeration tank, secondary and tertiary septic tanks, septic chamber for the accumulation of sediment. Models with a body made of metal is additionally equipped with the contact section of the tank to disinfect effluent before discharging into water body. The serial number of plants provides the possibility of their use in a range of performance from 3 to 200 m3/day. For private houses are two - trehsektsi-onnye Station COE-1 ", featuring one or two aerators (series" AO ") and a pump with a programmable timer. Purification efficiency is 95-99%. During a power failure the system goes into septic tank, and the resumption of power supply comes into operation within a few days, and add mikroorganiki not required. In plants provided decontamination effluent before discharge to the terrain, in a roadside ditch, ravine, waterbody.

Installation of deep biological treatment "Astra", "Cyclone", "Logo" from "SBM-GROUP" fully comply with Russia's climatic conditions and requirements Rospotreb-supervision. Applied even on quicksand and heavy clays. Durable polypropylene housing has ribs that prevent it from surfacing during a spring flood. The degree of purification - up to 98%. Work four-install all automatic. Equipment has a reliable Japanese compressor. Performance - 1 -20 m 3 / day. When using the facilities, "Cote-Bio Valley" from "SRIDS holding Energotech sinks successively pass through three stages: the stage of mechanical treatment in the septicemic cell block full biological treatment (aeration zone with a secondary clarifier) ??and filter unit doochi-stki (weakly loaded biofilter). The complex can be monoblock (capacity up to 2.5 m3 per day.), Or consist of separate blocks (up to 50 m3/day.). Tanks are made from metal, reinforced concrete, plastic. Configuration and design of loading material in the biological treatment unit eliminates the need to rinse or replace during the entire period of operation. Air for aeration is provided from the low-pressure low noise compressor installed in the room. Sludge from secondary clarifier is sent to the septic chamber automatically. Purified water from the filter doochi-stki pumped regular pump for relief. The removal efficiency of basic organic pollutants and suspended solids - 95-99%. The Finnish company UPONOR introduced this year its new development - the installation of a biochemical batch treatment of household sewage Uponor Bio, which differs from the above models using the precipitating chemical. Uponor Bio7 system performance 1.1 m3/day. designed to operate year-round with the number of living up to 7 people (in the range also includes device performance 1,5 and 2.2 m3/day).. Wastewater treated to the same portions. In this case, all items are treated uniformly, which creates ideal conditions for precipitation. Sedimentary capacity of 2 m 2 admits volley Discharges up to 500 liters, for example, when draining water from the bath. The system works as follows: from sediment tank, where the pre-deposition of particles and lighting waste, waste water is pumped into the production tank. The control unit transmits a command to the compressor, which pumps the air tank. Due to forced aeration accelerates the biological decomposition of organic substances (phase biological treatment). To select from the drains most of the phosphorus applied a neutralizing chemical. This process also controls the PC (phase chemical cleaning). One of the important functions of the computer Mitsubishi - maintaining a reservoir of comfortable conditions for the life of bacteria. In case of power failure the computer will start installing the operating mode automatically as soon as electricity is restored. One cleaning cycle takes 3.5 hours during the day may be 7 cycles. At the end of the purified water is discharged into a roadside ditch. But no matter what setting you choose, the construction of riparian buffer zones should be aware that in Russia there is virtually no local treatment facilities, followed by possible sewage discharge into the pond.
