AQUA-LATOR® SURFACE AERATORS COST-EFFECTIVE, HIGH OXYGEN TRANSFER EFFICIENT AERATION

Aqua-Lator® Surface Aerator Cross Section Overview The Aqua-Lator® floating mechanical aerator is used in a variety of wastewater treatment applications. Powerful pumping action transfers oxygen by breaking up the wastewater into a spray of particles, creating more surface area for atmospheric pressure to drive oxygen into the wastewater. At the same time, the oxygen enriched water is dispersed and mixed. The result: Effective wastewater treatment. The Aqua-Lator aerator represents over four decades of accumulated research and field testing in a broad range of municipal and industrial...

The Aqua-Lator surface aerator was introduced in 1963 and has a reputation for providing decades of superior performance and reliability. From the beginning, Aqua-Lator aerators have delivered excellent value for thousands of municipal and industrial wastewater operators. Driving this track record has been a consistent product philosophy of providing reliable performance, simplicity of operation and ease of maintenance. Satisfied customers span the complete range of wastewater treatment operations, from large city municipal treatment plants to the smallest village plant; from pulp and paper...

Mooring Accessories MOORING RING WIRE ROPE CLIP Mooring rings, manufactured of 304 stainless steel, are used to connect aerators together when the aerators are not moored to shore, posts, or concrete blocks. Heavy-duty shackles, manufactured of 304 stainless steel, are available in 3/16”, 1/4”, and 3/8” for use with the corresponding diameter mooring cable. The shackle is attached to the thimble. This allows for easy detachment of the aerator from the mooring line. Heavy-duty U-bolt clips, manufactured of 316 stainless steel, are available in 3/16”, 1/4”, and 3/8” for use with the...

Aerator Accessories ANTI-EROSION ASSEMBLY MIST ELIMINATOR™ SPRAY CONTAINMENT DOME The anti-erosion assembly consists of a standard intake cone with an integral plate, attached to the bottom. The anti-erosion assembly causes water to be drawn from the sides, rather than from directly below the aerator, thus helping to prevent bottom erosion that can sometimes occur in earthen basins. These assemblies are also used to prevent disturbance of the sludge blanket in facultative lagoon systems. The low trajectory diffuser (LTD) ring is bolted to the top of the discharge cone to lower the aerator...

Mist Eliminator™ Spray Containment Dome for the Aqua-Lator® High Speed Surface Aerator SPRAY CONTAINMENT DOME The Mist Eliminator™ spray containment dome is anoptional accessory for the Aqua-Lator® high speedsurface aerators. The dome controls the water flow from the powerful pumping action of the aerator at its discharge, redirecting it into the bulk liquid, thus minimizing mist and spray. Features The Mist Eliminator dome can also be used in installations where cold weather conditions might otherwise restrict the use of floating aerators. The domed cover acts to retain heat and enable the...
