WATER TREATMENT
Achieve the ratio of permeate and concentrate up to 70/30% (60/40, 80/20, etc.
depends on salinity, requirements for the quality of purified water, and the type of the
membrane element). The output capacity of the permeate should be
~ 125-375 liters /
h, and concentrate should be 180 to 540 l / h, depending on the model.
Attention:
Depending on the raw water quality and the type of membranal elements,
the ratio of concentrate and permeate can be changed. The optimum ratio of permeate
and concentrate can be provided after a full water analysis in order to evaluate the
quantity of cations and anions of the dissolved salts.
If the flow of concentrate or permeate is not correspond to the values, adjust the
flows of valves RV-02 and RV-03. Changing the flows and/or increasing the permeate
flow will result in scaling, which will reduce the interval between the cleaning
treatment and reduce the life of the RO membranes.
7.5.3
Check the working pressure and compare it with the results of the first test and
the technical characteristics.
7.5.4
Check the presence of water at the outlet.
7.5.5
Check the system for leaks, remove them if necessary. Before working de-
energized the system, release the pressure.
7.5.6
Check the concentrate flow.
Note: After the start of operation, write the display values of the RO system, they can
help to predict the regulation for system maintenance.
7.6 Operation
7.6.1 Pressure and the degree of regeneration.
The system works at a design pressure. The operator must adjust the release valve of
the concentrate so that the operating pressure should be 100-250 PSI (depending on
the type of membrane), a maximum of 250 PSI and flow permeate should be 50-90%
of the feed water flow. Guided by the following principles:
7.6.1.1.1
Pressure in the system should not be more than maximum allowable.
7.6.1.1.2
The capacity of the concentrate will be in the operation range.
7.6.1.1.3
Productivity for purified water (permeate) is calculated according to
temperature of raw water.
7.6.1.1.4
If the flow of permeate and total water consumption is reduced, system must
be flushed.
7.6.2
Replacement of membranes.
