EKO - Biological SBR Wastewater Treatment Plant
EKO-SBR on-site waste water treatment plants are intended for treating household waste water coming from single farms or `single-family` residential buildings when there are no possibilities of draining it to a collective sewage system.
The tanks can also double as underground storage tanks for rain water. They are also suitable for on-ground or over-ground installations.
The waste water treatment plant includes:
- two tanks: 2250 L and 1250 L for 4 -6 people,
- three tanks: 2250 L, 1250 L and 1250 L for 6 - 8 people,
- three tanks: 2250 L, 2250 L and 2250 L for 8 - 10 people,
- four tanks: 1250 L, 2250 L, 2250 L and 2250 L for 10 - 12people,
- a set (technical equipment) for the forebay / buffer chamber,
- a set (technical equipment) for the biological chamber (the last chamber is a biological chamber and a secondary settlement tank)
- control module,
- fastening materials,
- optionally extracted from the ground level of the column diffusers pump and mammoths.
The treatment plant is resistant to overload, fluctuations in temperature and temporary pauses in the supply of waste water. It can operate up to 2 weeks in a saver mode without the inflow of waste water.
Operation Principle
The SBR technology is based on sequential reactions where the treatment process runs cyclically. The main advantage of this type of plant is its relatively little sensitivity to fluctuation in the amount of in-flowing waste water when compared to a typical treatment plant with active sediment.
The first chamber acts as a preliminary settlement tank and a buffer tank where the waste water is treated mechanically through sedimentation of easily sedimentable suspended matter and the difference in load resulting from varying waste water inflow gets leveled. Pre-treated waste water is then directed to a SBR chamber where it is aerated and treated.
Aeration aims at supplying oxygen to microorganisms of the active sediments which decompose the impurities. Finally the treated water is ejected and the active sediment recirculated. The SBR plant works in treatment cycles. One cycle can be divided into several phases. Depending on the settings a cycles takes 7 to 8 hours to complete.
