An advanced modular wastewater treatment and recycling system, using technology from the U.S. military and the oil and gas industry, is now available for municipal users from Global Water Group, Inc., based in Dallas.
The company says this advanced extended aeration/activated sludge system processes water in half the time of conventional aeration systems. Using modular units, it operates with a separate recycling unit and a purification unit to produce recycled water that meets World Health Organization drinking standards. The process is easy to maintain and operate and produces no sludge, according to president and CEO Alan M. Weiss.
The systems accommodate flows from a few thousand gallons to tens of millions of gallons per day and are suitable for municipalities, industrial plants, and commercial and residential applications. Models can be built in standard or custom configurations.
Raw sewage passes through a bar screen. A super-diffuser system then introduces air to a digester, providing oxygen to sustain bacteria that devour the organics. The solution then flows to a clarification chamber where remaining solids float to the surface or settle to the bottom and are returned by a vacuum system to the digester. This maintains a high active bacteria count until the solids are eliminated.
The clarifier effluent flows to a Global Recycling System that captures all suspended solids down to 5 microns and returns them to the digester. The flow from the recycler enters a Global LS3 three-process purification system that removes parasites down to 1 micron, removes or significantly reduces hazardous chemicals, and disinfects with UV light.
