Industry accounts for nearly 60 percent of fresh water withdrawals in the developed world and agriculture consumes 70 percent of fresh water supplies globally, according to UNESCO. This puts tremendous stress on water resources and drives fundamental and increasing need for more efficient and cost-effective water supply and wastewater treatment solutions. Reverse osmosis (RO) is an effective and widely-applied technology for water treatment and desalination, yet current RO systems waste both water and energy. High recovery water treatment and effluent reuse are the only sustainable and cost effective solutions.
A new process is emerging that promises to improve nearly every aspect of RO performance.
Compared to conventional RO systems, semi-batch or closed-circuit (CCD) RO provides:
- High adjustable recovery rates
- Independently adjustable cross-flow
- Resistance to and even reversal of fouling and scaling
- Less energy consumption
- Fewer membrane elements and pressure vessels
