“It is well-known that membranes are susceptible to quick caking. The dirt typically sticks to the membrane wall, resulting in a rapid productivity drop. Until now, this problem was usually solved by increasing the crossflow velocity. Put simply, the pressure is increased. However, this requires a lot of energy. The Helix technology addresses this issue by creating an eddy current inside the membrane, thereby causing the particles to not stick at all.”
