When the effective pressure of the feed water is increased, the dissolved solids content of the permeate will decrease, while the permeate flux increases.
Performance and pressure
When temperatures increase and other parameters are continual, the permeate flux and the salt flow will increase.
Performance and temperature
The recovery means the relation between the permeate flow and the feed water flow. When recovery increases, the permeate flux will decrease and stagnate, when salt concentrations are of a value where osmotic pressure equals feed pressure. When recovery increases, the salt retention will decrease.
Performance and recovery
The effects of the salt concentration of the feed water on the permeate flux and salt retention are shown here.
