Ultrafiltration System Design
Since the beginning of our company, we are among the renowned organizations engaged in rendering Ultrafiltration System Design services. With an expert technical staff, we offer reliable services to our customers at cost effective prices. Ultrafiltration systems utilize an Ultrafiltration membrane, which is driven by pressure that helps to separate solid particles from solutions such as water. We use highly advanced technology and tools to rectify issues with machines and equipment. We complete Ultrafiltration System Design services as per the requirements of clients.
- Ethical business policies followed
- Rendered by a team of qualified engineers
- Reliable and authentic in nature
Ultrafiltration is used for the separation of suspended solids, colloids, bacteria and virus. This technique uses membranes with pore size between 1-100nm. Ultrafiltration technique requires 103-105 MWCO(molecular weight cut-off)* Da
There are 4 membranes geometries:
Spiral wound module: this design tries to maximize surface area in a minimum amount of space. It is the less expensive but more sensitive to pollution due to its manufacturing process. It consists of consecutive layers of large membrane and support material in an envelope type design rolled up around a perforated steel tube.
Plate and frame module: it is normally used for bad quality water. They are set up with a stack of membranes and support plates.
Tubular membrane: Generally used for viscous or bad quality fluids. These modules do not need a preliminary pre-treatment of the water. As the feed solution flows through the membrane core, the permeate passes through the membrane and is collected in the tubular housing.
The main drawback is that the system is not very compact and has a high cost per m2 installed and it is not very compact. Diameter’s tube is generally between 4 and 25mm.
Hollow fiber membrane: The modules contain several small (0.6 to 2 mm diameter) tubes or fibers. As the feed solution flows through the open cores of the fibers, the permeate is collected in the cartridge area surrounding the fibers. It can carry out the filtration in two ways, either “inside-out” or “outside-in”
