Global plants feature a modified activated sludge design based upon accepted technology that has been successfully used in the United States for many years. Many applications reuse the water for irrigation, or discharge into clean streams, rivers or lakes. The benefits of a "package plant" are combined with custom designed features for an attractive solution where raw sewage is or has been a problem.

The primary separation basin accepts raw sewage and retains it for a minimum number of hours, typically four. The basin provides automatic separation of solids, having the heavier solids settled down to the bottom.

The water separated from the solids and the floatables, flows into the aeration basins to be aerobically digested within the activated sludge design. The flow leaving the aeration basins has been processed both anaerobically and aerobically and enters the final settling basin. Floatable matter will rise in the basin and solids will settle into the bottom. Floatable matter is returned to the primary separtaion basin by use of an air lift pump. Solids are returned to either the first aeration basin or to the primary separation basin by an air lift pump. When a cycle is completed, the activated sludge settles in the bottom of the settling basin. The treated and processed water flows out of the settling basin over the v-notched weir. When using chorine, a disinfection basin provides enough detention time to disinfect the water. An aerobic sludge digester is optional and allows wasting of the sludge. The duplex motor/blower unit provides the necessary cfm of aeration to the basins and air lift pumps.
