ULfine
Ultrafiltration fiber characteristics
- Extremely small filtration pore diameter. The use of membranes with a nominal pore diameter of 0.02 µm allows to remove pathogenic organisms and the majority of virus and bacteria. The high porosity of the membranes allows high flow with low pressure loss.
- Durability. The structure and manufacturing process ensures high stability and durability of the membranes, even with frequent cycles of chemical cleaning.
- Configuration. Membranes that function on pressure and with internal to external flow are applied. Each membrane has 7 longitudinal holes (with 0.9 mm or with 1.5 mm of diameter) through which water passes to be filtered. The pressure forces the passage through the wall of the membrane, filtering the water in an extremely effective way.
Module details
- The systems ULfine are composed of low pressure ultrafiltration modules. The fibers are encapsulated in PVC modules, vertically assembled. The special design of the module includes an internal distributor that allows an almost constant radial velocity.
- Integrity guarantee. The modules are sealed and do not require any seal to separate the water entrance area from the ultra-filtered water. During the cleaning process, the fibers are not subject to great oscillations. This reduces mechanical strain and maximizes the membranes’ lifetime.
Innovation
- The MX series of ULfine has an innovative design that avoids the necessity of a water tank for the membranes’ cleaning. Cleaning is done individually, by module sections, with water produced by the remaining.
- Greater efficiency. The MX unit continues the water production even during the cleaning. In conventional systems, this water must be produced before the cleaning, reducing the useful time of production.
- Minor occupied space. The absence of a water tank significantly reduces the space occupied by the system.
- Lower effluent flow. The cleaning by module sections implies a reduction in the effluent flow. The oversizing of the rejection pipes is not necessary.
