Oasys Water enhances ClearFlo for better control and capabilities


Oasys Water, a provider of membrane-based solutions to transform industrial wastewater into valuable freshwater resources, has enhanced its ClearFlo technology platform.

The new ClearFlo MBCx dramatically extends the capabilities of the company’s flagship forward osmosis (FO) based system by increasing system flux by more than 100 percent, while integrating a sophisticated controls capability to provide far greater system flexibility and performance, to aggressively driving down system life cycle costs.

The MBCx makes high recovery brine concentration and ZLD viable for new applications, such as extending fresh water production from seawater desalination plants where intake expansion is not feasible or where environmental pressures on brine discharge are growing.
In Oasys’ current applications, the MBCx greatly expands the economic value to customers.

For example, in the Oil & Gas industry where the total cost to treat produced water applications can now be reduced below $2 per barrel, which is competitive with transport and injection well disposal in most cases, the MBCx expands opportunities in this market just as Oil & Gas begins a long awaited recovery, Oasys said.

Oasys CEO Jim Matheson said, “The MBCx represents the largest leap forward for Oasys’ award winning technology in our eight year history.”

The latest innovation has allowed them to break the back of many of the previous limits facing membranes for industrial wastewater applications; both for FO and RO based systems, Matheson added.

In addition to extending the performance envelope for high salinity brine concentration, Oasys has adapted the MBCx to handle high recovery, water reuse for wastewater streams in the brackish water range of 5,000 – 25,000 mg/L of total dissolved solids (TDS).

MBCx systems optimized for brackish streams provide recovery of 90 percent or greater from sources such as cooling tower blowdown, food and beverage production wastewaters, electronics wastewaters, and other sources, which until now have been limited to treatment with high pressure RO at recovery levels of 70 percent or less.

The MBCx dramatically reduces wastewater volumes for discharge to evaporation ponds, to publicly operated treatment works (POTWs), or for final treatment in zero liquid discharge (ZLD) scenarios.

Oasys will begin delivering MBCx systems to its partners and customers starting in early 2017 following completion of an active pilot testing program across a variety of wastewaters and applications.

The innovative MBCx platform arrives as Oasys continues to aggressively expand its commercial efforts beyond China and the Oil & Gas industry, where its technology was initially commercialized beginning in 2014, the company said.
