Community wastewater treatment plants

ROTOSET COMMUNITY WASTEWATER TREATMENT PLANTS

RotoSET community sewage treatment plants are intended for facilities with no access to the sewage system. The use of RBC rotating biological bed technology allows to achieve exceptional treatment efficiency with unparalleled ease of operation and very low operating costs. The technology has been known and appreciated all over the world for over 70 years, and the use of sophisticated materials makes it applicable for dozens of available series and applications up to 800 inhabitants in one tank.

A characteristic trait of the RotoSET sewage treatment plant is its foolproof structure and the lack of mechanical air injection into the tank, thus minimizing the risk of unpleasant odors escaping from the tank. The shaft movement is ensured by a low-speed, quiet, energy-saving motor with a durable gear.

Due to uneven wastewater flows in a number of facilities, the devices are fit with the FlowSET flow balancing system. FlowSET uses the movement of the shaft and the installed overflow vessels to feed a constant amount of sewage to the bed zone, ensuring the same cleaning time by aerobic bacteria.

All RotoSET devices are made from Glass Reinforced Polyester (GRP), which is well- known in the aviation, chemical and pharmaceutical sectors. Due to exceptional ring stiffness, tightness and resistance to aggressive environment, GRP is the perfect fit for a sewage treatment plant tank

AN INVESTMENT FOR YEARS

The technology of rotating biological contactors is characterized by low operating costs. The main cost of daily operation is electricity. The geared motors used in RotoSET devices are known for their low demand for electricity. The costs of long-term operation are mainly influenced by the costs related to the replacement of consumables and service, as well as the disposal of primary and secondary sludge. Owing to a foolproof structure, wastewater treatment plants contain few consuming components and the technology itself generates a minor amount of excess sludge.

SPECIFICATION

GRP TANK

Exceptionally strong and robust monolithic GRP tanks allow to cut down installation costs and minimize the occupied space.

NO ODORS

The devices do not use mechanical injection of air into the sewage environment, so the solution is considered odorless.

SAVINGS

RotoSET sewage treatment plants are characterized by a foolproof structure without devices such as pumps, blowers, diffusers, solenoid valves, or complicated control automatics.

QUIET OPERATION

The low-speed gear motor works under the cover, generating virtually zero noise. There are no external aeration systems.

RELIABILITY

Low energy consumption, no need for biopreparations, a large settling tank
and a simple design allow to reduce operating costs to a minimum.

PROCESS AUTOMATION

Proper operation requires no biopreparations, inoculation with active sludge; after long interruptions in the sewage supply, the membrane will rebuild spontaneously.

SEWAGE DOSAGE

The FlowSET system balances the flow through all chambers, ensuring an optimal retention time of wastewater in each chamber.

POLISH MANUFACTURER

When choosing Bio-Set devices, you bet on peace of mind, protect the environment, but also contribute to the development of Polish technologies.

COMPLIANCE

RotoSET devices have been tested in line with PN-EN:12566-3+A2:2013, thanks to which they hold the European CE certificate. The plant also meets the requirements of ISO 9001:2015.

Container sewage treatment plants

RotoSET container sewage treatment plants are a type of above-ground devices that allow for quick and easy change of location. They can be used as new wastewater treatment systems, as well as an upgrade of the existing ones.

The devices are characterized by a compact design with integrated settling tanks. Thermal insulation enables use in any climatic conditions. A single container can handle from 100 to 225 REs, while for larger projects it is possible to set the containers in parallel. This solution can be used up to 2000 REs.

Prices

The costs of a complete domestic sewage treatment plant, including assembly, infiltration system, connection, documentation, etc. may vary considerably depending on the number of people in the household, soil and water conditions, distance, and the technology adopted.

The lower costs are favored by well-drained soil, low groundwater level, small recess for connection and short distances between the building, the treatment plant and the sewage receiver. In such conditions, the cost of the complete system equals several thousand zlotys. More people in the household, poorly permeable land, high water levels often increase the costs to more than PLN 20,000.
