Membrane units are widely used in the water treatment industry, since they can be applied both for removing relatively large formations - dispersed and large colloidal impurities, and for recovering small colloidal particles and dissolved compounds.
The microfiltration / ultrafiltration unit is a compact, functionally complete module. The main module equipment, instrumentation, piping, control and shut-off valves are mounted on a metal frame. Automatic control over the switching of the modes of operation of the module is provided by the controller and the set of automatic valves. The module operates in a batch mode, the main mode is filtration, where treated water is supplied to the UV permeate collector. Periodically, it is necessary to flush the membrane module, which is carried out automatically. In addition, the module is disconnected periodically from the filtering process and a chemical flushing of the module is carried out manually using the CIP-station. The frequency of flushing, as well as the list of reagents used for flushing, depends on the quality of the treated water.
Micro- and ultrafiltration membranes have pores with a diameter from 1 to 0.05 microns (1 μm = 10-6 m) and operate normally at pressures of 2-5 bar. The units are supplied in a complete set and include pumping and dosing equipment, reverse and chemical flushing systems for membrane modules, and automated process control systems.
