Aeration & Clarification

Schreiber’s Continually Sequencing Reactor™ (CSR) offers the only system in the industry that allows for biological nutrient removal (BNR) and enhanced nutrient removal (ENR) in a single basin. This allows industrial and municipal plants to separate aeration and mixing functions. Use of controls and analytical devices allow for tight control bands around dissolved oxygen (DO) or other preferred parameters.

Schreiber’s mixing apparatus includes a suspended set of headers fitted with our proprietary diffusers. The mass of diffusers allows for a gentle mix and robust flocculation. The diffusers are always entering an area of low to zero DO as the bridge moves the mass through the basin.

Schreiber’s clarifiers make aeration easy and energy efficient, with spiral collectors providing for rapid sludge removal in less than a single revolution of the scrapers. No dewatering is required for service or maintenance—and less maintenance is required, thanks to a peripheral drive that avoids “twisting” while supplying support in the center and at the edge. When used with Schreiber CSR and RAS pumps, there’s no need for floc wells, as excellent floc is maintained throughout the system.

The Schreiber Continuously Sequencing Reactor, or CSR, is a Biological Nutrient Removal (BNR) system contained in a single basin. It produces the three process phases required for BNR—oxic, anoxic and anaerobic—in one basin, performed sequentially and repetitively over time. During Learn More

Schreiber’s Peripheral Drive Clarifiers are favored because of their ability to accomplish rapid sludge removal and continuous collection and removal of floatables. Instead of the typical center-drive high torque arrangement, Schreiber Clarifiers utilize the mechanical leverage and mechanical simplicity of Learn More

Behind all of Schreiber’s patented methods for biological wastewater treatment, our process controls provide users with the ability to run their operations. FlexControl monitors and controls the chemistry used by your biological reactor throughout all three phases of wastewater treatment: Learn More
