Purification system

Abstract

A system and method is provided for filtration and purification of a liquid. A purification system can be used for filtration and purification of water. A system can include a raw water treatment system, an ultra filtration system, a reverse osmosis purification system, and a solar power system. A purification system can include hardware and controls for decreasing energy use and system inefficiency by monitoring and controlling temperatures of individual components, of the system, or of the purified liquid. A purification system can include a wetted ground and ground monitoring system control or improve the effectiveness of a ground.
