Ultrafiltration Membranes

Types tangential flow microfiltration membranesBasically the membranes are classified in ceramic or minerals, and organic membranes:

CERAMICS

• Compact and tube geometry.• tube diameter 2 to 6 mm.• Flow filtration, inside and out.• High mechanical strength, thermal and chemical processes very suitableindustrial.• very long lifetime.• Facilities bulky, there are large dead volumes.• very high construction costs, are the most expensive.• Large losses, heating problems.High energy consumption.

HOLLOW FIBER

• The membrane consists of a bundle of hollow fibers within aporous distributor with ends sealed with epoxy resin• Inside diameter 0.9 to 1.7 mm• Radial flow within the fiber, the inside out• Resist high pressures• By its configuration, are mechanically very strong and very suitableto filter wine (large amount of suspended solids)• The materials used are: polysulfone (PS), polyethersulfone (PES),polyolefin (PO) and others.
