Idroconsult - Ultrafiltration Under Vacuum System

This technology is winning great market success thanks to its economic price and to its ease of cleaning. The typology most adopted by Idroconsult is that with hollow fibres. The chemical inertia remains high, as the materials utilised are mainly PP and PE. This is the most suitable choice for high treatment capacities. The system generally used by our company entails the use of ultra-filtration membranes with hollow fibres, which are immersed in the water to be treated. These membranes, which look like very thin tubes, are arranged in bundles and bound at the ends. They are quite flexible, which helps when washing them. The material treated by the membranes is indeed removed on a periodic basis by shaking the actual membranes. This is done by regularly blowing air into the tank through submersed diffusers. They may also be counter-washed in counter-current by means of a pump. Their composing material (polypropylene) enables them to twist without consequent damage.
