Aeration Equipment

Brown Bear Series R31

Brown Bear R31 series paddle aerator attachments for sludge drying and aeration of compost windrows attach to high-flow skid steers and high-flow compact track loaders. They are designed to be used with flows of up to 50 gpm and pressures up to 5,500 psi. The aerator can be used for accelerated drying of all types of potable water and wastewater sludges, hydrocarbon-petrochemical sludges, industrial and mining sludges and for aeration of compost windrows. The 31-inch-diameter aerator provides an economical mechanical solution for accelerated solar drying of sludges on pads and in drying beds, forming windrows, blending bulking agents or additives, pulverizing and aerating or water mixing for aerobic windrow composting. The rapid handling rate exposes all of the material to oxygen so noxious odors are minimized. Drive to the aerator rotor is through the high flow hydraulic system of the carrier. 641-322-4220; www.brownbearcorp.com

Park Process VortaFlo

The VortaFlo static mixer from Park Process combines two mixing nozzles of different sizes to create turbulence and induce mixing. The addition of the injection quill allows chemicals or polymer to be injected in the mixing zone past the turbulence-creating nozzle prior to passing through the mixing nozzle. In the case of polymer flocculating biosolids, the turbulence nozzle causes the biosolids to roll in the mixing chamber so the polymer has maximum contact with biosolids particles prior to passing through the mixing nozzle, where flocculation is promoted. It is available in sizes ranging from a 1-inch inlet/outlet and 2-inch mixing chamber to a 12-inch inlet/outlet and 20-inch mixing chamber. 855-511-7275; www.parkprocess.com

By reducing ozone doses and using lower-capacity ozone equipment versus conventional ozone-only treatment, treatment plants may reduce capital costs and energy consumption. The advanced process does not require upstream RO or UF membranes commonly used with other types of direct and indirect water reuse schemes. 215-997-4000; www.denora.com

SBRs

Parkson PISCES CFSBR

Parkson’s PISCES CFSBR (Continuous Fill Sequencing Batch Reactor) combines the process benefits of cyclical treatment with the simplified operating concept of continuously filling all reactor tanks at all times. All required treatment steps occur within the reactors, eliminating the need for clarifiers and sludge recycle. Treatment is accomplished utilizing an aeration step followed by settle and decant. Treated effluent is removed from the upper portion of the basin by a DynaCanter floating, solids excluding decanter. The DynaCanter does not require any in-basin actuators or drive mechanisms to control the unit, making operation and maintenance convenient. The unit can be provided with several aeration types including VariOx jet aeration and fine or coarse bubble diffused aeration (fixed and retrievable). The cycle steps are dynamically adjusted utilizing DynaPhase Control software so that process performance and energy consumption are optimized during all flow conditions. 888-727-5766; www.parkson.com
