  • Documentation

NEREX ultrafiltration membranes are used to purify tap water, water from wells, and boreholes and allow it to be purified from bacteria, viruses, microorganisms, colloidal and suspended particles, the size of which exceeds the pore size of the membrane. Filtration degree 0.05 microns. The water obtained after the membrane is completely safe for the body and does not contain organic decomposition products, disinfectants, etc.

The maximum dirt holding capacity is 10 grams.
The filter cycle is calculated by the formula:
10 / (turbidity or suspended solids in water) = volume of water before the next manual flushing of the membrane.

Ultrafiltration Advantages

There are several reasons to consider Ultrafiltration as an excellent choice for pretreatment as opposed to conventional technologies:

1. Ability to cope with difficult and variable waters: Ultrafiltration membranes are a physical barrier against most particles, suspended matter, colloids, bacteria and even viruses, that can produce an excellent water quality independently of variations in the influent water quality.

2. Improved and more consistent product quality: Due to their fine pores, ultrafiltration membranes can provide a very high quality filtrate, with typical ultrafiltrate turbidity less than 0.1 NTU (independent of the raw water turbidity), SDI less than 3%/min and 6-log or more removal of pathogens such as Cryptosporidium and Giardia cysts.

3. Lower environmental impact: Conventional systems typically require chemical pretreatment such as coagulation and pH adjustment for the removal of silt and fine particles, but UF can remove these contaminants just by size exclusion due to the small size of the membrane pores. This can lead to lower chemical consumption and lesser environmental concerns for wastewater disposal.

4. Lower RO stage cost: The potential for lower downstream cost, based on improved and more consistent water quality facilitated by the UF system, is a key aspect. UF as pretreatment also allows higher design flux in the RO stage, as well as lower requirements for membrane cleaning and ultimately lower replacement rates, by facilitating a RO feed water with lower fouling tendency. In addition, cartridge filters use can be significantly reduced or eliminated (especially when there is no break tank in between UF and RO).
