Powell Water - Microalgae System (PWMAS) Lagoon Optimization
The PWMAS provides lagoon aeration via microalgae (biological oxygen generators) that greatly improves wastewater treatment compared to both non-aerated lagoons and aerated discharging lagoons and can be done at a much lower lifetime cost compared with surface aerators. A robust and diverse community of microalgae is used for aeration of a wastewater lagoon. Unlike the cyanobacteria that forms a surface mat on lagoons and lakes, the microalgae utilized by the PWMAS, disperses evenly within the lagoon, thus providing 100% available oxygen for microbes to remove the incoming waste product –also known as biochemical oxygen demand (BOD5). Every structure and supporting equipment included in the PWMAS is used to maximize the growth of the microalgae and microbes; therefore, maximizing overall wastewater treatment.

The PWMAS includes a systems control facility for the production and distribution of site-specific microalgae and microbes. The following is a description of the major components of the PWMAS.
