Product Overview
CM Aquatechnik supplies sequencing batch reactor (SBR) systems for simultaneous BOD, nitrogen, and phosphorus removal in a single tank using automated fill/react/settle/decant cycles. SBR technology provides excellent nutrient removal flexibility, low footprint, and simple operation — making it ideal for municipal and industrial applications with variable or intermittent flows.
Frequently asked questions
How does an SBR plant work?
All treatment steps take place in a single tank in an automated cycle of fill, react, settle and decant. The cycle time is adjustable between 3 and 8 hours, and the PLC controls the sequence and adjusts aeration intensity based on dissolved oxygen measurement.
What effluent quality can an SBR achieve?
Typical effluent values are BOD below 5 mg/L, total nitrogen below 8 mg/L and total phosphorus below 1 mg/L when the enhanced biological phosphorus removal (EBPR) cycle is used. The actual results depend on the influent composition, temperature and the chosen cycle design.
Is an SBR suitable for variable or intermittent flows?
Yes, this is one of its main strengths. The variable cycle time handles wide fluctuations in influent flow and load, which makes SBR well suited to industrial estates, food and drink plants and small communities, with plant capacities from 50 to 10,000 m³/day.
What information do you need for a quotation?
Please provide your average and peak daily flows, influent BOD, COD, nitrogen and phosphorus concentrations, and the discharge limits that apply. Details of the available site area or existing tanks and lagoons, and any preference for the aeration system, help us to prepare an accurate design. Send us your requirements and we will prepare a proposal within 48 hours.
