Dow Water & Process Solutions has introduced the Tequatic Plus fine particle filter to the China and European markets in October and November respectively, The move comes one year after its launch in North America. 
 
Since then, the company has said, it has gained momentum in many applications for difficult, high-solids water, including industrial wastewater treatment and reuse, and is supported by a recently opened manufacturing facility in California.  
 
“Customers around the globe have a growing need to protect important water resources with a cost-effective, high-performance solution,” said Cedella Beazley, business unit director, Filtration, DW&PS.  
 
“The Tequatic Plus filter can help customers improve the efficiency of their operations while also reducing their environmental footprint through, for example, less waste, high water recovery and high uptime.”
 
The filter combines the power of continuously cleaning, cross-flow filtration with centrifugal separation and solids collection into one device to meet the demands of extreme water environments. It is unique to the tough water space, reliably handling very high and highly variable total suspended solids up to 10,000 mg/L without frequent filter changes – even in the presence of oil. These and other features enable it to overcome the shortcomings of conventional technologies such as bag and cartridge filters.
 
John Patrin, global marketing manager, Filtration, cited a recent success in the wastewater treatment and reuse market at a meat processing plant.
 
“When integrated into an existing wastewater treatment system, the TequaticPlus filter removed 98% of the solids above 20 microns – using a 35-micron filter – in a feedwater stream containing total suspended solids levels of 2,000 mg/L above 20 micron,” he said.  “This was achieved with no fouling or backwash cycles, and with a 99% water recovery.” 
 
Consequently, the customer extended the time between bag filter changes from 10 minutes to 60 minutes, and improved the performance of the downstream ceramic filters.
