Rotoset domestic wastewater treatment plants

RotoSET domestic sewage treatment plants are intended for the treatment of domestic wastewater from households without access to the sewage network. Exceptional treatment efficiency with unparalleled ease of use was achieved thanks to the innovative technology of rotating biological deposits RBC. This technology has been known and appreciated all over the world for over 70 years, and the use of cutting-edge materials makes it fit for domestic applications. 

A characteristic feature is the uncomplicated design and the lack of mechanical air injection into the tank, thanks to which there are no unwanted odors escaping outside the tank. Rotary movement is ensured by a low-speed, quiet and energy-saving gear motor, which, apart from its longevity, requires no servicing. 

Due to an uneven wastewater inflow in households, the RotoSET series devices use the FlowSET flow balancing system. FlowSET uses the movement of the shaft and installed overflow vessels to feed a constant amount of wastewater to the bed zone, guaranteeing the same cleaning time by aerobic bacteria.

The devices have been tested in line with the requirements of PN-EN: 12566-3 and subsequent amendments, therefore the product holds the European CE certificate. All RotoSET devices are made from GRP (Glass Reinforced Polyester), which is a material known in the aviation, chemical and pharmaceutical industries. Owing to high ring stiffness, tightness and resistance to the wastewater environment, GRP is ideal as a tank for sewage treatment plants. 

The horizontal (Type A) or vertical (Type B) tank design permits adapting the model to the local conditions and individual preferences of the investor. By default, the tanks are available in a natural GRP color and with an aesthetic green cover.
