The energy of amount, but there is also two sets of circulatory systems, while the limitation of compressed machine row pressure, it can only provide compared with low-grade heat source, produce
The not high problem of fresh water rate.
Freezing is seawater icing ice-melt to be produced to the technology of fresh water, but there is also two kinds of media, two sets of circulatory systems, produce light
The not high problem of water rate.
Reverse osmosis (RO) technology of embrane method is a kind of selective penetrated property using semi-permeable membrane, is made under conditions of plus high-pressure
Water against concentration gradient penetrate semi-permeable membrane, and make salinity and impurity stay in film the other side technology.Hyperfiltration is generally by electric energy
It being driven with mechanical energy, system needs to maintain higher operating pressure, and it is very high to the voltage endurance capability requirement of equipment, while needing to consume
It is lower to produce fresh water rate for a large amount of high-grade energy.
