CLR Process

Whether it’s a new treatment facility or an existing plant upgrade, the Lakeside Closed Loop Reactor (CLR) Process provides effective biological treatment for superior performance and consistent high quality effluent. The CLR in conjunction with the Magna Rotor Aerator is an extended aeration, complete mix system. Utilizing long solids retention times provides stable operation over a wide range of influent flow and organic loadings, minimizing the time and effort needed to control or adjust the system. Even in cold weather conditions when microorganism activity is decreased, the process operates efficiently without special attention.

Multiple basin configurations are available; the standard racetrack design, the Multi-Loop Reactor with concentric multi-channels for process control and the Vertical Loop Configuration for applications with limited space.

Using nonproprietary designs, Lakeside offers Biological Nutrient Removal (BNR) with the addition of submersible mixers and/or recirculation pumps. Total nitrogen and phosphorous removal is achieved by cyclic or phased isolation operation within the reactor or by incorporating external anaerobic and anoxic tanks.

Magna Rotor Aerators & Accessories

The Magna Rotor Aerator provides oxygen to the biological mass and mixes the microorganisms uniformly to prevent solids from settling in a biological treatment system. With excellent mixing capabilities, the Magna Rotor makes it possible to sustain high concentrations of microorganisms so that variations in organic loading and shock loads are easily absorbed by the system. The wide range of oxygen transfer allows the plant operator maximum flexibility to match the demand of the system. With the proper combination of speed and blade immersion, optimum performance can be maintained to match virtually any condition. Oxygen enrichment efficiency is further enhanced by the flow control baffles. Optimum performance of the Magna Rotor offers reliable operation, high efficiency and the lowest operating power cost throughout the life of the equipment.

Fiberglass rotor covers are available to contain mist and spray without restricting the performance of the Magna Rotor Aerators. Besides ensuring a clean working environment for the plant operator, the fiberglass covers reduce heat loss during winter operation. The rotor covers include hinged panel sections for easy access to inspect the rotor assembly.

Sequencing Batch Reactors (SBR)

A cost-effective solution for your biological treatment process, the Lakeside Sequencing Batch Reactor (SBR) provides superior performance and consistent high quality effluent. The fully automated system treats raw wastewater flow in a single basin using timed based phases to fill, mix, aerate, settle, decant and waste sludge. The two types of processes available are the conventional Sequencing Batch Reactor (SBR) and the Continuous “feed” Sequencing Batch Reactor (CSBR).

The SBR incorporates diffused aeration with mixers to provide excellent mixing and aeration for high oxygen transfer. The innovative designed decanter minimizes decanting intervals while extending the biological process time. The resultant clear water discharges without foam or floating scum.

The CSBR process is a continuous feed system that enhances the superior technology of the conventional SBR. The CSBR system allows raw wastewater to continuously flow into the reactor basin during the treatment cycles including during the settling and decanting phase. A baffle wall prevents short-circuiting as the flow travels from the reactor’s pre-react zone and equally distributes the flow into the main react zone where aeration, settling and decanting occur.

SpiraGrit Vortex Grit Chamber

Efficiently remove inorganic grit from the treatment plant in a mechanically induced vortex environment. The SpiraGrit efficiently removes grit over a wide range of daily flow rates. Rotating paddles maintain the flow velocity in the vortex chamber, keeping organics in suspension while allowing heavier grit to settle on the chamber floor. The settled grit moves across the floor and falls into the lower grit hopper. A grit pump sends the captured grit from the lower hopper to a Grit Classifier or Raptor® Grit Washer for separation and dewatering. The grit pump can be either an airlift pump, self-prime pump or a recessed impeller pump.

Hydronic T Series Trash Rake

Clean bar screens, trash racks and intake screens at wastewater treatment plants, storm water facilities and water intake structures with Hydronic T Series Trash Rake. Telescoping designs are available with single and multiple sections to fit your operational needs. Since the rake mechanism is independent from the bar rack, the Hydronic T Rake does not require guides, sprockets or chains and has the ability to clean at rack inclinations up to 90-degrees. All moving parts can be accessed from above the channel for ease of operation and maintenance.

Whether choosing the stationary or traversing rake, the Hydronic T can withstand the toughest applications plants have to offer.

Hydronic K Series Trash Rakes

Clean bar racks up to a depth of 100 feet with the hydraulically operated Hydronic K Series Trash Rake. The articulating design gives the rake arm a long reach suitable for manual surface skimming and removing large objects, such as trees, barrels and rootstocks. It is available as a stationary, swiveling or traversing unit providing the right fit for your operation.

Raptor® Fine Screen

Unlike conventional bar screens, the Raptor® Fine Screen’s characteristic cylindrical screenings basket, angled installation and screen bars of varied heights increase removal efficiency and minimize headloss. The Raptor® Fine Screen’s rotating rake teeth fully penetrates the cylindrical screen bars, positively removing debris and grease to prevent blinding or plugging. Captured screenings are compacted, dewatered and washed free of most organic materials to approximately 40 percent solids. Volume is reduced by 50 percent and weight by 67 percent, resulting in reduced disposal costs.

Raptor® Micro Strainer

Ideal for small treatment facilities, the Raptor® Micro Strainer is a screen with a semi-circular basket with small apertures ranging from 0.04 to 0.25-inches (1 to 6 mm). It captures small debris that passes through other screens. A perforated plate or wedge wire basket is available for municipal or industrial applications. The captured screenings are washed, compacted, and dewatered to a dry solids content of 40 percent as they are transported up the inclined screw for disposal. This step reduces the volume by 50 percent and weight by 67 percent, ultimately reducing disposal costs.

Raptor® Rotating Drum Screen

An excellent screenings solution for applications requiring removal of small particles, the Raptor® Rotating Drum Screen’s high removal efficiency meets the needs of Membrane Biological Reactor (MBR) designs. Using either a perforated plate or wedge wire basket with openings ranging from 0.02 to 0.25-inches (0.5 to 6 mm) this screen is ideal for either municipal or industrial applications. Captured screenings are compacted, dewatered and washed free of most organic materials to approximately 40 percent solids. Volume is reduced by 50 percent and weight by 67 percent, thereby reducing disposal costs.

Package Treatment Plants

An economical treatment system to biologically process wastewater, the efficient Package Extended Aeration Treatment Plant provides superior performance in meeting your effluent discharge limits. The compact design is suitable for small communities, housing developments, trailer parks, schools, and industrial applications. Two types of Extended Aeration Systems are available; the E.A. Aerotor Plant and the Packaged Extended Aeration Plant.

The E.A. Aerotor Plant is constructed in a concentric common wall design that incorporates the Closed Loop Reactor (CLR) Process in the outer loop for extended aeration and mixing, while the inner area has the peripheral-feed Spiraflo Clarifier for final settling. Alternatively, a second outer channel could be added for stand-by capacity, allowing efficient treatment for seasonal flow variations and promoting biological nutrient removal.

The Package Extended Aeration Plant is a pre-engineered system that contains screening, diffused aeration, clarification, disinfection and sludge holding into one pre-fabricated steel tank. This system, which is ideal for smaller applications, is shipped as a complete package ready for easy installation. Alternatively, the Package Plant components could be shipped for installation in concrete structures as well.
