Dual reverse osmosis units for arsenic, boron and bacteria removal. Each unit has two 2.5" x 20" pre-filters for the UV (visible in corner at left). In the forefront of the picture are the pure water storage tanks. This system is for a single-dwelling home as their well is highly contaminated with boron and arsenic and they have no other water source.
