Environmech Sdn. Bhd. since 2012: Enmech Aspirating Aerator Jet Aerator (Surface Aerator)

Enmech aspirating aerator is an efficient aerator to be installed in aerating tanks, basins, aerated lagoons and rivers/canals for municipal and industrial wastewater treatment. The hi-grade material air jet is directly mounted at an adjustable angle with the motor portion and air intake above the surface, and the propeller portion below the surface.

The motor rotates and turns the hollow shaft along with the propeller and drives the water at a high speed near the propeller blades. The air above the water level is drawn via the air intake port and goes into the hollow shaft. Turbulent flow created by the propeller breaks up the air into small bubbles along the water streamline, mixes in the basin and disperses oxygen. Maximum oxygen transfer can be achieved by increasing bubble hang time via horizontal water movement.

Features

The aerator parts are made from stainless steel 304/316 or engineering plastic depending upon water quality.
Aerator synchronous speeds are 1,500 rpm and 3,000 rpm.
Ceramic or stainless steel sleeve is installed at the shaft end bearing, when uses in common water.
There is no end bearing model for the high-strength cantilever hollow shaft, which means no bearing problem when used in abrasive water.
Installation is available both in fix and float types. F

Benefits

Creates effective horizontal water movement to limit algae growth and distribute oxygen over a wide area.
Operates quietly without spraying or splashing for year-round performance.
Reduce odours by injecting oxygen and providing water movement.
Directs circulation into most areas as the aerator angle adjusts to control the amount of circulation and depth of the bubble stream. Easy to move and install by one person (we recommend a registered electrician to do all the wiring).

Application

Sewage

Aeration, re-suspension and circulation of oxidation ditches, the aerobic treatment of sewage effluent, mixing, consolidation and treatment of sludge, improved digestion resulting in the ditch returning to its original handling capacity.

Fish Farms

The total flexibility in-depth and position gives the high volume of entrained air which is the perfect choice for fish rearing tanks, growing cages and fishing lakes.

Environmental Use

Oil spillage recovery, ranging from slight oil-contaminated cooling water to heavy pollution after oil spillage and to the removal of water bound larvae e.g. mosquitoes

Application Guide

This guide is written to assist the user of Lambda aspirating aerators in the effective and efficient sizing and application of this product. When making a recommendation for Lambda aerators you must carefully consider mixing and oxygen requirements, as well as the configuration of the processing system.

How is it applied?

Enmech aerators can be mounted on floats, basin walls or bridges. They are fully adjustable with several mooring options available to fit specific basin geometries. Multiple aerators can

be used depending upon the basin size. These aerators can be used in different shaped tanks, lagoons and oxidation ditches. Typical positioning is presented on the left.
