Ultra Filteration

Dew Speciality Chemicals Pvt Ltd offers Ultra Filteration. Ultrafiltration (UF) is a separation process using membranes with pore sizes in the range of 0.1 to 0.001 micron. Typically, UF membranes will remove high molecular-weight substances, colloidal materials, and organic and inorganic polymeric molecules. Low molecular-weight organics and ions such as sodium, calcium, magnesium chloride, and sulfate are not removed by UF Membranes. Because only high-molecular weight species are removed, the osmotic pressure differential across the UF Membrane surface is negligible. Low applied pressures are therefore sufficient to achieve high flux rates from an Ultrafiltration membrane. Efficient and effective water treatment generally requires a combination of different methods and technologies. This combination depends on the intended purpose of the cleaned water (e.g. drinking water, industrial process water for power plants, etc.) as well as on the quality and degree of contamination of the original water. Thanks to its unique advantages, ultrafiltration can play a central role in this mix of physical, chemical and mechanical processing methods. Dew manufactures ultrafiltration plant containing in tubular, hollow fiber, spiral and flat sheet membrane configurations. UF is a low pressure process for separating larger size solutes from aqueous solutions by means of a semi-permeable membrane.
