Asio - Model AS-VARIOcomp K -Domestic Wastewater Treatment Plant
A line of fully equipped domestic wastewater treatment plants designed for the treatment of sewage from single family homes. Based on a stable and reliable operation, the plant technology keeps energy consumption to a minimum. This technology uses aerobic biological processes that have been proven by long-term application in practice.
- Certification in accordance with EC legislation
- Low operating costs
- Complete delivery (everything included in the price, incl. extension and cover)
- Insulated, lockable, walk-on cover
- Easy operational handling and reliability
- Possibility of simple conversion from a conventional wastewater treatment plant (WWTP) to the ULTRA type, by the insertion of a membrane module
- If the ULTRA type is used, pre-treated water can be used as sanitary water
Wastewater flows to the settlement compartment (A) of the inlet part of the wastewater treatment plant (WWTP), where floating and sedimentable solids are removed, which are further subject to anaerobic degradation. From the settlement compartment, mechanically pre-treated water flows to the activation compartment (B) through an overflow. The activation compartment (B) is used for the biological treatment of wastewater. In its bottom part, this compartment is fitted with a fine-bubble aeration system into which air is forced by means of a blower and possibly a biomass support (C) to improve the process stability of an overloaded or partly loaded wastewater treatment plant (WWTP). An advantage of this design is the storage capacity (D) throughout the entire space of the treatment plant, which is designed to store wastewater and to ensure an even outflow of wastewater from the treatment plant. The activated mixture from the activation compartment flows to the vertical secondary settlement tank (E); from there, treated water is extracted with a mammoth pump (F) to the outlet trough. Excess aerobically stabilized sludge is extracted with a mammoth pump to the settlement and sludge compartment (A) as necessary.

The wastewater treatment plant is installed in an excavation on a concrete slab base (there is no need to cement the plant at the sides), connected to the sewerage system by means of orifices, and the air line of a blower located outside the WWTP is connected to it. The blower is installed outside the treatment plant to extend its service life, as the environment inside the WWTP is very aggressive. The basic functions are pre-set by the manufacturer and the WWTP does not require any electric installation workexcept the connection of the blower to the mains. The wastewater treatment plant is put in operation by the supplier or an authorized service organization. Given their dimensions and weight, the 5 and 8 EO types can be transported on a car trailer and be placed in the excavation without the use of a crane. The wastewater treatment plant (WWTP) is equipped with an insulated, lockable and walk-on cover, 980 x 870 mm, as a standard feature.
- Technology of the wastewater treatment plant (WWTP) - 24 months; plastic shaft - 5 years.
- ASIO, spol. s r.o. is a holder of the ISO 9001:2000 quality certificate.
- The AS-VARIOcomp treatment plant types conform to the latest European standards.
The structure of the tanks is designed using the calculation method of end elements, with the use of the NEXIS calculation program, for a service life of 25 years.
