UAB “BUITEKA LT” is making aerobic domestic wastewater treatment plants that treat wastewater biologically. Quality of the plant’s operation is guaranteed by well-known technological and innovative technical solutions.
The plant is ecological. The aerobic microorganisms present in the plant decompose pollutants of wastewater biologically, do not emit unpleasant smell, and treated wastewater are harmless and odourless
The plant has one container – no primary treatment or additional (tertiary) treatment are needed
The plant is operating silently as it has no moving parts
Easy to maintain
The treatment principle of domestic wastewater is biochemical oxidation by active silt under aerobic conditions. Aerotank and secondary precipitator with all the necessary elements are installed in one round container in the shape of cone (see Table 1). Recirculation of active silt is spontaneous (silt slides from the secondary precipitator down to the aeration unit along the slope of conical bottom (angle with horizon is 50°)). The air blowers of necessary pressure and effectiveness are used for aeration.
Type of plants | Amount of treated wastewater m3/d | Number of people | Permitted load of the plant with pollutants Kg/d | Power of air blower W | Air blower pressure kPa |
|---|---|---|---|---|---|
NVB-1 | 0,5 - 0,8 | 2 - 4 | 0.24 | 51 | 14.7 |
NVB-2 | 0,8 - 1,2 | 3 - 7 | 0.42 | 51 | 16.7 |
NVB-3 | 1,4 - 2,0 | 8 - 14 | 0.72 | 95 | 17,7 |
NVB-4 | 1,9 - 2,8 | 13 - 17 | 1.02 | 125 | 20 |
NVB-5 | 3,2 - 4,5 | 18 - 25 | 1.56 | 210 | 20 |
