Title: SYSTEM FOR PURIFYING A LIQUID
Abstract:
The invention relates to systems for purifying and/or desalinating a liquid. The present system comprises a valved raw liquid supply line, which is connected to a filtration unit comprising a liquid purification means with an inlet and with outlets for purified liquid and drain liquid, a mixing device, a means for maintaining pressure, a means for maintaining a recirculating flow of liquid, which is located on a line supplying a mixture of raw liquid and concentrate upstream of the liquid purification means, a recirculating line, a purified liquid line, a drain liquid line, and a control unit, which is connected to all of the following: the means for maintaining pressure, a means for monitoring changes in pressure, the raw liquid supply valve and a drain liquid discharge valve. The means for maintaining pressure is located on a raw liquid supply line upstream of the liquid mixing device, which is in the form of a head tank connected to a raw liquid and concentrate mixing line. The technical result is a longer system working life, more efficient use of raw liquid, and reduced energy expenditure.
