ROTEK’s Ultrafiltration (UF) systems feature high-performance membranes with a 0.01μm pore size, specifically engineered to remove high molecular weight substances, colloids, bacteria, and organic/inorganic polymeric contaminants. These UF membranes ensure superior water clarity while maintaining energy efficiency, consuming only 20% of the power required by traditional reverse osmosis (RO) systems. Designed for low-pressure operation, they deliver high flux rates and stable performance.

ROTEK Auto-control Filter with Multi-Media Sand as the filtration media is designed to deliver exceptional performance by utilizing high-quality components. It is engineered for longevity and energy efficiency. This Multi-Media Sand Filter (MMF) efficiently removes impurities from water by passing it through a bed of quartzite sand with varying gradations. Installing a Sand filter is recommended when the water`s turbidity load is high, causing water quality issues and deposits on pipelines, boilers, taps, and appliances.
