Description
Technical Field
The utility model relates to a influence the water treatment fields such as the product water yield and quality of water of embrane method water treatment because of temperature variation, relate to like hemodialysis treatment facility, GMP water treatment facility, ultrapure water equipment technical field, especially relate to a water treatment system temperature compensating system.
Background
Reverse osmosis membrane, nanofiltration membrane and ultrafiltration membrane are one of the membrane products which are widely applied at present, and the performance of the reverse osmosis membrane, the nanofiltration membrane and the ultrafiltration membrane is easily influenced by some external factors, so that the quality of the outlet water is changed along with the influence of the external factors, and the factors are required to be understood in detail. The effect of the feed water temperature on the membrane performance is mainly reflected in its effect on the membrane rejection rate, and its effect on the membrane operating pressure and pressure drop. The permeability of the membrane increases as the temperature increases and the net driving force required decreases as the water flux remains at a fixed value, thereby reducing the actual operating pressure. At the same time, an increase in temperature will increase the permeability of the solute, i.e. the salt permeability, which will increase the conductivity of the produced water. Temperature effects on the pressure drop across the membrane the reaction process is such that as the temperature increases, the molecules in the water become relatively mobile, causing the viscosity of the water to become lower and the pressure drop to decrease. The increase in temperature increases the salt permeability and decreases the salt rejection, and the increase in temperature increases the rate at which salt permeates through the membrane, thereby increasing the amount of salt permeating through the membrane. In order to make the film product exert the maximum use value, various factors which can influence the film performance must be accurately controlled, the working performance of the film is improved by changing external factors, and the production efficiency is improved for enterprises.
The pure water required for hemodialysis is generally prepared by a reverse osmosis method. The key of the reverse osmosis system is a reverse osmosis membrane, which is a material made of high polymer and has very small pores, so that most dissolved ions and various microorganisms in water can be separated, and water molecules can permeate through the pores of the reverse osmosis membrane. Generally, the water fluidity and the water temperature are in a direct proportion relationship, that is, the higher the water temperature is, the better the water fluidity is, the influence of the low temperature in winter is caused, the fluidity of tap water for preparing pure water is reduced, and the pure water quantity of a reverse osmosis system permeating a membrane is obviously reduced, so that the pure water equipment for hemodialysis cannot meet the demand of hemodialysis. In the process of equipment type selection, the equipment type needs to be increased to make up for the reduction of water yield in winter, and obviously, the equipment investment cost is increased.
When the temperature is reduced, the permeability of the membrane is reduced, and when the water pressure is kept at a fixed value, the water yield of the membrane is reduced, so that the water demand is influenced due to insufficient water. Conventionally, the problem of insufficient water amount caused by low-temperature environment is solved by increasing and designing the number of amplification membranes.
Improvements are needed to address the above issues.
