Sustainable Wastewater Management

Advanced Wastewater Technology

Water Oxygenation

Our patented wastewater technology systems can be retrofitted.

Pictured is a 12.5 KL/day plant we constructed. The process remains the same for plants from 12 500 L/day up to 120 000 L/day. The blocks expand and increase parabolically as treatment capacity increases.

Please note that we possess the capability to design, construct, commission, train and maintain/operate all of our technologies. We work with strategic partners where needed.

An Investment That Makes Huge Net Profits

How does It Make money?

Treated sludge can be sold as fertiliser.

Treated effluent can be sold as recycled water and/or drinkable water (by adding a Sand Filter/Reverse Osmosis Filter and final disinfection).

A Cashflow-Generating investment with a short payback period, whilst making millions of dollars in net profits.

How does it work?

Waste water is mixed with activated sludge in mixing the chamber
Sludge mixture is pumped to the biofilter sprinkling system by the circulation pump
Falling drops are broken upon the disks and sprinkled across the biofilter feed
Liquid exiting the biofilter feed is collected in collection tray
Sludge mixture is conveyed by air-stripping towers to the aeration zone of the aeration tank
Natural aeration with shock treatment and bubble flow in aeration zone
Sludge from settling zone is pumped back to the mixing chamber completing the cycle
Pure water is collected in the collection trays in the settling zones and gravitates to anoxic zone for denitrification
