General Filter Aerators Aeration and Gas Stripping

Aeration Experts General Filter products and processes have treated water supplies since 1935. Now part of the WesTech product line, General Filter continues to be a leader in the design and manufacture of many of today’s proven treatment technologies. With over 1,000 installations, aeration technologies are prominent among those many innovations. WesTech provides all types of aerator systems – from pressure aerators and cascade aerators to positive draft designs. Our aeration manufacturing material has evolved from redwood to steel to fiberglass and finally aluminum. The General Filter maintenance-free...

Induced Draft Aerators Induced Draft Aerators are most often used for the oxidation of iron from groundwater sources, enabling the oxidized iron to be removed by downstream clarification and filtration equipment. The aerator can also remove some unwanted dissolved gasses like CO2, stabilizing the pH of the water and reducing the chemical requirements for lime softening and post reverse osmosis filtration. Induced Draft Aerators utilize an axial flow blower mounted on the top of the unit to pull air into screened air inlet hoods located on the lower side of the aerator housing. This blower creates...

Aerator Materials Aerator Housing The corrosion-resistant, all-aluminum housing provides a chamber for the countercurrent flow of water and air. Standard housings are available for capacities ranging from 65 to 3,600 gpm. Larger custom sizes are also available. A hinged and bolted removable side is furnished for internal access. All aerators have a media inspection port. Inlet and exhaust air ducts are screened and baffled to prevent water loss and debris entrance. The moisture separator at the top of the aerator unit provides multiple changes in air direction for minimal moisture carryover....

ATOMERATOR™ Pressure Aeration ATOMERATOR Pressure Aerators force finely diffused air into a stream of moving water under pressure in a manner that ensures intimate contact between the air and all particles dispersed in the water. They are ideal for oxidation of iron which can then be removed by filtration in a pressure filter system. The ATOMERATOR unit eliminates the need for a chemical oxidant. ATOMERATOR Pressure Aerators effectively treat groundwater for iron removal within the proper design criteria. Pilot treatment units are available for onsite process verification. Outlet Features • A...

Cascade Aerator Cascade Aerators work by natural air draft. Water flows from the top of the unit, splashing off of the cascading trays, exposing water droplets to air naturally flowing past the unit. Cascade Aerators have no moving parts, require no electricity, and are maintenance-free. Cascade Aerators are best applied for oxidation of iron by addition of oxygen followed by detention and filtration. They are Ideal for iron concentrations above 10 ppm as the open structure eliminates fouling due to iron precipitation. They can also be applied to increase dissolved oxygen at the end of wastewater...
