The filter incorporates continuous cleaning, cross-flow filtration and centrifugal separation and solids collection which allows users to filter high and variable solids while achieving a water recovery of 99% or more.
Applications for the filter include industrial wastewater treatment and reuse, produced water for oil and gas, desalination and industrial water treatment. Vertical markets range from food and beverage and pulp and paper to textile and laundry.
One recent application for Dow's filter was tobacco fibre recovery prior to wastewater discharge using a 30 micron screen upstream of the vacuum plate filter. In another example, a customer in Shandong, China, was experiencing fermentation solids losses in liquid purification from wine and high operating costs. To solve this problem, a Tequatic Plus filter, also fitted with a 30 micron screen, was installed. A pulp and paper manufacturer in Jiangsu, China has also made user of the filter to improve performance.
