What should be the distance from the monoblock plant to the air blower room?
- If possible, the distance should be minimized, to avoid loss of air pressure. If the electrical equipment will be placed in a residential building, it is necessary to consider that the monoblock plant BIOTAL sanitary protection zone is 5 m. In the case, if nearby the plant there is no existing building for placing the compressor, you can either build a special light structure of sandwich panels, or purchase a box-recuperator.
How to choose the capacity of the plant for the petrol station?
- Based on our experience operating the sewage treatment plants of petrol stations, we recommend that, when calculating the flow rate, you take into account not only the employees of the petrol station but also the customers who use the sanitary facilities. The minimum wastewater flow rate must be at least 3 m³/day. Since such objects are characterized by a large uneven flow of wastewater, it is necessary to provide a sewage well with a submersible pump before the BIOTAL plant, which will supply sewage to the plant. The feed pump is connected to the control unit of the BIOTAL plant, which makes it possible to shut off the supply pump at the maximum water level in the plant and prevent its flooding.
At what distance can the BIOTAL plant be placed from the gas supply pipe?
- Placement of the plant regarding existing underground utilities is regulated by building regulations, namely, DBN 360-92*.
How to choose the right pumps for treated water pumping?
- In order to determine the parameters of the pumps for purified water pumping, it is necessary to know the daily capacity of the BIOTAL plant, the mark of the surface of the ground near the plant and at the point where the purified water is discharged, and the length of the pressure pipelines. The pump discharge flow can be determined by dividing the daily flow rate of the plant by the number of operating cycles per day (10 cycles). For example, the flow rate of the purified water pump of the BIOTAL-50 plant with a capacity of 50 m³/day will be equal to 5 m³/day. The pump pressure is determined by hydraulic calculation in accordance with the initial data. To increase the reliability of the plant, it is necessary to provide a reserve pump for pumping the treated water. Pumps should be equipped with floats that control the switching on and off of pumps.
How to determine how much space the drainage will take?
- To determine the size of drainage, it is necessary to conduct engineering and geological surveys of the site of treatment facilities. The drainage area will depend on the soil filtration coefficient. As a drain, sand-gravel filters can be used (at the expense of treatment facilities up to 20 m³/day) or modern drainage systems, for example “Stormbox”.
We need to purchase a plant for an office building. How to choose the right capacity?
- Plant capacity in this case should be calculated on the basis of the norms “Domestic water supply and sanitation.”
How can I find out whether industrial wastewater can be treated with BIOTAL technology?
- You must send the analysis of the wastewater to be treated to the BIOTAL representative, and be sure to specify the type of production and the method of water disposal provided for in the project.
Are metal hoisting brackets used for servicing the reinforced concrete part?
- Metal hoisting brackets are not used in the reinforced concrete part of BIOTAL plants, since they would be exposed to corrosion from the aggressive environment. In general, during the construction of the reinforced concrete part for our plants you should pay particular attention to ensuring waterproofing, both external and internal.
What should be the ceiling height in the blower room for a monoblock plant?
- The ceiling height in the blower room should be at least 2.5 m for ease of maintenance.
