Abstract:
A method of treatment of liquid including supplying liquid to be treated to at least one liquid treatment module having a liquid inlet, a permeate outlet and a brine outlet, monitoring liquid pressure within the at least one liquid treatment module and upon exceedance of a liquid pressure threshold in the at least one liquid treatment module, reducing the liquid pressure in the at least one liquid treatment module by performing at least one of the following functions: opening a liquid pressure reducing valve at the brine outlet, increasing a liquid volume output of a circulation pump which removes brine from the at least one liquid treatment module, equilibrating liquid pressures between a liquid pressure inside the at least one liquid treatment module and inside a liquid feed tank and opening a liquid pressure reducing valve at the liquid inlet.

Claim (Index 1):
A liquid treatment system for treatment of feed liquid, the liquid treatment system comprising:\n at least one liquid treatment module comprising at least one membrane and in communication with a liquid inlet, with a concentrate outlet, and with a permeate outlet; a high pressure pump which normally maintains a fixed output liquid volume notwithstanding variations in liquid pressure at an outlet of the high pressure pump, the high pressure pump exhibiting an energy consumption that is a function of the variations in liquid pressure at the outlet of the high pressure pump, the high pressure pump being operative to pressurize a feed liquid to be supplied to the at least one liquid treatment module via said liquid inlet; a circulation pump for circulating a concentrate from said concentrate outlet to said liquid inlet for the pressurized feed liquid to be mixed with the concentrate, to result into a mixed liquid to be supplied to said to the at least one liquid treatment module via said liquid inlet; and a controller configured for:\n controlling the high pressure pump; \n monitoring the liquid pressure downstream from the high pressure pump; \n determining that the liquid pressure downstream from the high pressure pump has reached a predetermined high pressure threshold representing exceedance of a salinity threshold of the concentrate; and \n immediately after said determination, lowering the liquid pressure downstream from the high pressure pump to a level which exceeds an osmotic pressure of the feed liquid, thereby immediately reducing the energy consumption of the high pressure pump.
