Membrane filtration technologies are most effective in water treatment. It is possible to obtain potable water from surface and underground sources with a high degree of purification from impurities and microorganisms. In case of wastewater treatment of municipal enterprises – water that is suitable for industrial use, and in the treatment of industrial wastewater – recycled water.
Membranes used in water and wastewater treatment processes can be classified by pore size and, accordingly, by the size of trapped impurities into micro-, ultra-, nano- and hyperfiltration (i.e. reverse osmosis).
In contrast to traditional methods (mechanical filtration, physico-chemical treatment, disinfection), which require large areas and a large number of staff with associated operating costs, membrane technologies have a number of undeniable advantages:
- compact equipment and ease of increasing power;
- reliable barrier filtration and fairly low energy consumption;
- the ability to fully automate the processing and quality control of water.
However, for efficient operation of membrane equipment without loss of productivity in “clean” water during the declared life, it is necessary to carry out continuous maintenance, namely, the treatment of water with chemical reagents that prevent the formation of mineral and biological deposits in the membrane pores – with antiscalants and ITS WATER™ biocides.
If during operation of the membrane equipment from the moment of its commissioning antiscalants and biocides were not used, it is recommended to pre-flush the equipment using washing agents of ITS WATER™.
