Sigma design approach to wastewater recycle treatment systems has significant advantages and display the following salient benefits:
o Advanced design, but easy to operate.
o Consistent performance providing uniform recycles water quality.
o Utilization of ultrafiltration technology as pretreatment to a reverse osmosis system.
The ultrafiltration pre treatment provides consistent water quality since it is an absolute membrane barrier. The reverse osmosis system shall provide a chemical free and a more competitive means of treatment to obtain recycle water with TDS less than 5 mg/L, if required.
o Compact skid mounted system requiring minimal space.
o Modular design with built in expansion capability.
o Low operating costs.
o Competitive capital costs. .
