Biwater SWRO-SM Series Reverse Osmosis Systems can either be designed and built as skid mounted units, component modular units (where space is limited) or containerised units (ISO containers) for fast and easy site installation.

Standard systems from 14,000 to 250,000 gallons per day (63-1,140 m³/d) are available.
Larger capacity custom designed systems are also available and can be tailored to meet your specific site requirements with capacities up to 1,500,000 gallons per day (6,800 m³/d).

Biwater Service engineers are available for technical support to ensure that your system is always operating and producing water as designed and built.
