Dow Water develops flexible filtration solution

Dow Water & Process Solutions has introduced the Tequatic Plus, a new solution to water challenges in Europe specifically targeted at non-potable water applications.

The solution’s applications include industrial wastewater treatment and reuse, produced water for oil and gas and desalination. It is engineered to lower the total cost of ownership in extreme and variable high solids environments.

The technology combines the power of continuous cleaning and cross-flow filtration with centrifugal separation and solids collection. It has the flexibility to function as a primary filter and a pre-filter for ultrafiltration (UF) and reverse osmosis (RO).

The Tequatic Plus fine particle filter can also function as a post-filter with water reuse technologies like moving bed bioreactor (MBBR) and dissolved air flotation (DAF).

The filter was produced by Clean Filtration Technologies (CFT), a subsidiary of The Dow Chemical Company.

CFT general manager Cedella Beazley said that the Tequatic Plus filter is a breakthrough in the tough water space, reliably and cost-effectively handling very high and highly variable total suspended solids, and overcoming the shortcomings of conventional technologies.

"The Tequatic Plus filter is adept at handling solids from 1mg/l to 10,000mg/l without frequent filter changes, even in the presence of oil," Beazley said.

"Because it requires minimal filter changes and chemicals, the Tequatic Plus filter can help customers reduce the footprint of their operations through, for example, less disposal, minimal handling and less space along with potential energy efficiencies."
