PAN (Polyacrylonitrilic) is a naturally hydrophilic material that gives high filtration flow rates for very turbid water. Its characteristics mean that cleaning frequency is low and maintenance requires only a limited use of chlorine. This is an ideal material for waters with low TOC loads guaranteeing minimal investment and operating costs. It is also favorable to sustainable development as its use is synonymous with absence of polluting chemical discharges.

For water likely to cause ‘fouling’ (presence of TOC, algae, etc.) or when ultrafiltration pretreatment is very limited; membranes have to be cleaned more regularly with strong chemical agents. In these conditions, a polysulfone membrane able to withstand a wide range of pHs is the most appropriate solution.

Purez UF has solutions suitable for every size of plant. They can be used alone or can be integrated into a complex treatment line.

• Drinking water (all origins)

• Ultra-pure process water (pharmaceutical or electronics industries, bottling, etc.)

• Recycling and re-use of municipal or industrial wastewater (cooling systems, golf courses and gardens, road cleaning and vehicle washing, process water, etc.)

• Desalination
