Process Separation by Membranes
Advanced membrane technologies tailored specifically for water treatment applications
*PROMEM™ Trademark
At Diva Envitec, we specialize in providing advanced membrane technologies tailored specifically for water treatment applications across various industries. Our Poresep membranes, including Reverse Osmosis (RO), Nanofiltration (NF), and Ultrafiltration (UF), are engineered to meet the stringent demands of water purification processes in pharmaceutical, biotech, food, beverage, and dairy sectors.
Our team of experienced engineers collaborates closely with clients to identify the most suitable membrane solutions for their unique water treatment requirements. Through comprehensive consultation and data collection, we tailor-fit our engineered membrane solutions to meet specific application needs.
From initial project initiation to full-scale implementation, we conduct thorough lab and pilot plant work to size, design, and cost-effective industrial-scale water treatment plants.
Our membrane systems utilize a variety of materials of construction configured in typical cross-flow mode. By capitalizing on differences in physical and molecular sizes, as well as ionic charges, our membrane technology effectively removes insoluble or soluble molecules such as protein complexes, triglycerides, fats, oils, bacteria, colloidal matter, and fibers from water streams, regardless of their incoming concentrations.
With over 35 years of experience in membrane-based applications, our engineers have successfully supported a wide range of water treatment applications, including:
We offer a diverse range of membrane types suitable for various applications and process conditions:
RO MEMBRANES: TFC membranes, Cellulose Acetate
NF MEMBRANES: Modified Polyacrylonitrile, PVDF, Ceramic, PES
UF/MF MEMBRANES: Polyamide, PVDF, PTFE, Cellulose, Low Protein Binding Polysulfone, Ceramic, Stainless Steel
Our membranes are available in different molecular weight cut-offs (MW) or micron sizes, catering to specific filtration requirements.
Our membrane solutions find applications in a myriad of water treatment processes, including:
✅ API/Chemical nano-filtration for desalting applications
✅ De-ashing of products using membrane technology in conjunction with hybrid processes like Ion Exchange
✅ Caustic/Brine recovery from industrial effluents
✅ Dye effluent treatment for removing color/dye from water
✅ Dye recovery in dyeing houses
✅ Desalination Membranes
✅ Degreasing of rinsers and baths in industries such as steel and automotive
✅ Acid/Pickling/Electroplating for recovering precious metals and removing precipitated heavy metals
✅ Treatment of emulsions and suspensions
✅ Wastewater Treatment – tertiary treatment using UF, NF, or RO membranes
Our commitment to innovation, quality, and customer satisfaction ensures that our membrane solutions deliver unparalleled performance and reliability in water treatment applications across industries.
