KLARO MAX system up to 5,000 PE / 750 m³ per day
SBR technology is proving to be an optimal process for treating wastewater in small sewage treatment plants. The strict separation of the process phases results in a variety of control options for the purification process. This in turn allows for economic construction, operation and powerful purification capacity of the plants.
For these reasons, we have implemented SBR technology for wastewater treatment plants beyond our standard sizes (up to 1,500 PE / 225 m³ per day) and extended its use to plants up to a connection size of 5,000 PE / 750 m³ per day.
The procedural concept includes the technical dimensioning with individual design of the wastewater treatment plant components. Depending on requirements and local conditions, this includes mechanical pre-treatment, pumping stations, pre-storage, biological treatment stage(s), sludge storage and treatment, and reuse of treated wastewater.
Essentially, the concept provides two variants:
1. Single-train SBR plants with upstream storage tank (pre-storage)
Range: Up to 3,000 PE / 450 m³ per day
The single-train SBR plants are always implemented with pre-storage so that no untreated wastewater flows into the SBR basin during clear water withdrawal. Only one SBR basin is required for these plants. The pre-storage allows for volume and concentration equalisation, decouples the inflow from the cycles in the SBR basin, and ensures short-term supply.
2. Double-train SBR plants without pre-storage
Range: Up to 5,000 PE / 750 m³ per day
The two-train SBR plants are usually implemented without pre-storage. The inflowing wastewater is first fed into the first SBR basin, and then into the second SBR basin. As a result, return contamination of the purified clear water is prevented by inflowing wastewater, even without pre-storage.
