MEMBRANE FILTER SYSTEMS - CROSS FLOW OR TANGENTIAL FLOW
RO, NF, UF, MF systems are being used in the industry for varied applications - starting from bio-pharmaceuticals, chemicals, dyes and F&B industry.
Membranes of Cellulose, Polyamides, PP and/or Ceramic for more toxic, rugged and tough applications are designed and supplied by Diva Envitec. A range of media is available to handle applications in the Pharmaceutical, Biotech, Chemical, F&B, Wines and Breweries, Dyes, colours and Dye Intermediates etc.
Our objective is to fully satisfy customer requirements with respect to process and operational details, engineering standards and equipment selection, cost- effectively, ensuring that the engineered system continues to function efficiently for many years. Diva Envitec’s technical team works closely with customers in order to reduce development lead times and minimise investment risk. Customers benefit from Diva Envitec and its principals extensive experience in process development and a flexible approach to design and manufacture. We have a good experience in trouble-shooting existing membrane filtration plants and also help companies with start-ups.
