Awaseku offers a variety of wastewater treatment systems which are designed as Sequencing Batch Reactor (SBR) systems. The modular design enables effective treatment of wastewater flows ranging from 500 GPD (1.9 M3) to 200,000 GPD (760 cubic meters). All systems have been thoroughly tested and proven through 35 years and thousands of installations worldwide. The systems can also be designed for denitrification (biological nutrient removal) and recycling for irrigation and toilet flushing.

Awaseku can provide solutions for failed septic systems, and allow development of land where conventional sewage systems cannot be used. These systems enable land developers to proceed with construction even when central sewers are several miles away, or years in the making. Awaseku not only offers wastewater treatment systems, but also Chlorine Contact Tanks, Equalization Tanks, and Sludge Processing Tanks.

There are numerous benefits to our waste water treatment systems. The system is easily installed; it’s a modular construction which is easily expanded. There are no offensive odors and there is no offensive noise.

Customer/Operator on-site training and service after the sale are provided by Awaseku. Company project and process engineers are available to assist with specifications, design work, and troubleshooting on existing systems.

This is an example of a typical cycle:

Fill: Aeration  Flow enters the solids Retention Section (A) which is separated by non-corrosive screen. Inorganic solids are retained behind the screen. Organic solids are broken by turbulence created with mixed liquor being forced through screen by submersible aeration pumps. This eliminates the need for mechanical comminution.
Aeration  Liquid and small organic solids pass through the screen into the continuing Aeration section (B). Air and mixing are provided by submersible pumps with venturi aspirators that receive air through pipe intake pipe from the atmosphere.
Denitrification (Optional)  Provided by an anoxic period during the regular treatment cycle. Cromaglass units create anoxic conditions by closing the air intakes of the aeration pumps with electric valves. This stops aeration, but the system continues mixing.
Transfer/Settle  Treated mixed liquor is transferred by pumping to the Clarification Section (C). The transfer period overfills the Clarifier with the excess spilling through overflow weirs back into the main Aeration Section. Transfer ceases and Clarifier (C) is isolated - solids separation occurs under quiescent conditions.
Discharge  After settling, effluent is pumped out of the Clarifier (C) for discharge. Sludge is returned from the bottom of the Clarifier (C) back into the main Aeration Section (B) using a submersible pump, or sludge can be wasted to a Sludge Processing Tank.
