Lakeside has more than 35 years of oxidation ditch experience leading to the development of the present day Closed Loop Reactor (CLR) Process. With more than 1,700 installations, the CLR Process is proven to be reliable, flexible and efficient.

The CLR Process is a modified form of the extended aeration, complete mix process, with the design based on a single sludge system in a closed loop reactor. Typical designs use oval configurations, providing a straight line flow pattern for wastewater between headworks and final clarification. At the core of the CLR is the horizontal, bladed Magna Rotor to sustain high concentrations of microorganisms and maintain process control. Another component of the CLR is the Spiraflo Clarifier, which uses peripheral-feed flow technology proven to be superior for effective solids separation.

To provide flexibility, Lakeside’s CLR is available as parallel, series and peak flow hydraulic capacity operation.  With the addition of submersible mixers or pumps, Biological Nutrient Removal (BNR) is possible – in single-stage, MLE and alternating cycle designs.

Lakeside Rotor Covers are ideal to contain mist and spray created by the rotor aerator without restricting its flow pattern.  They are wider than other covers on the market, combining 3-, 4- and 5-foot panels to cover various lengths of rotors.
