Background technology
With the improvement of living standards, the pure small-sized household that can directly drink of water quality and commercial water purification machine are increasingly popularized, and it is pure
The cost of water dispenser in use is mainly reflected in two aspects, is the utilization rate and filter core service life of water respectively；Water
Utilization rate is mainly reflected in the net expense ratio and concentrated water recovery utilization rate of water purification machine；The net expense ratio of water refers to water purification machine per one liter of output
The ratio of pure water and the concentrated water discharged, per 1 liter of pure water of output, its discharge concentrated water is that 2-3 rises concentrated water to common water purification machine at present,
There are many water purification machines that concentrated water recycling filtering is used to increase pure water yield to reduce concentrated water discharge, but its consequence brought is to lead
The hardness and pH value for causing pretreated water increase, and accelerate reverse osmosis membrane and filter core at different levels to block age hardening, increase filter core, pump valve more
