Both the depth and time of flooding can be controlled to influence the flow of nitrogen and phosphorus . The water draining from Cell 2 is divided into adjustable proportions controlled with a splitter valve . For example, a portion may be recirculated back to the septic tank to enhance nitrogen transformations and the remainder disinfected by UV light prior to distribution into the greenhouse. The partially cleansed water is further filtered within the soil and plant roots of the greenhouse planter boxes. The planter boxes are designed to store or transform the small concentrations of nutrients left within the water.
Chlorine is added to water leaving the greenhouse as a final disinfection stage.
The reclaimed water is now ready for reuse to flush toilets, irrigate the landscape, or to fill an aesthetic pool. Water exiting all components of the system will be analyzed monthly for microbiological and chemical content.
