Green Excellence!!! Welcome to GRENEX

The AquaSBRR is unique in its ability to act as an equalization basin, aeration basin and clarifier within a single reactor. Normally, the process follows basic steps of Fill, Reactor, Settle and Decant. The ability to create aerobic or anoxic conditions within the reactor results in flexible operation, better treatment of waste and because the AquaSBR operates in a true batch treatment mode, optimum effluent quality is obtained during each cycle.

Operaion

The use of microprocessor controlled phases enables the operator to vary the operating strategy of the AquaSBR to suit treatment requirements

	1. Mixed Fill Influent enters the AquaSBR reactor. Complete mix of the reactor contents is achieved without use of aeration. This phase assists in control of filamentous organisms and is essential for those systems which require phosphorus removal.
	2. React Fill Influent flow continues under mixed and aerated conditions. Aeration may be intermittent to promote aerobic or anoxic conditions. Nitrification and denitrification can be achieved. The aeration source may also be operated intermittently during low flow and organic loading conditions to conserve energy.
	3. React Influent flow is terminated, while mixing and aeration continue. Intermittent operation of the aeration system may continue to complete the nitrification - denitrification process or to conserve energy.
	4. Settle Mixing and aeration cease. Solids/liquid separation takes place under perfectly quiescent conditions.
	5. Decant/Sludge Waste The mixer and aeration system remain off and at this time the decantable volume is removed by means of subsurface withdrawal. The reactor is immediately ready to receive the next batch of raw influent. A small amount of sludge is wasted each cycle.
	6) Idle Occurs in multiple-basin systems anytime that flow conditions are less than peak design flow. Idle time varies depending on actual flow conditions.
