MEMBRANE
SYSTEMS
With increased awareness towards green technology and sustainability, there is a demand for having a technology which can be used to selectively separate or purify desired molecules from a solution. Since we have the known proverb “Necessity is the mother of invention”, membrane systems based filtration technology has gained demand which harnesses the power of semi-permeability to achieve precise separation of materials. This technology, used in membrane systems, operates on the principle of size, molecular weight, and other distinctive characteristics-based separation, purification and further concentration of it—finding application in varied areas of industrial processes.
The membrane being made with versatile material like PES, PVDF, etc., works on the principle of hydrodynamic mass transfer model. Those molecules which are larger than the pore size of membrane gets rejected thus generating 2 different parts of the solution. A cross flow filtration method is far more beneficial than a dead-end process reducing the fouling rate of the membrane. This tangential filtration flow is a pressure driven process.
At Sanitech Engineers, we specialize in manufacturing a cutting-edge membrane-based filtration system which can incorporate any configuration of membrane right from ceramic, spiral, hollowfibre and cassette tailored to meet the unique filtration challenges faced by process industries. With handholding to customers requirement using our tailored systems has help us in establishing ourselves as one of the trusted and leading membrane system experts throughout India, with a proven track record of successful implementations across various industrial projects.
