Introuduction
RO system is widely used in preparation of water for beverage
industry, which features adaptable of different salt content of
water, easy operation, less labor force and low running cost.
1. Pre-treatment System.
Pre-treatment system is composed of mechanical filter, active
carbon filter, scale inhibitor and precision filter. The water
temperature requires 25± 30C.
Flocculator is used for destroying electro-neutral of colloid in
water, which ensures raw water can reach to the requirement of Silt
Density Index (SDI) ≤ 4. Mechanical filter can remove most of
suspension, colloid and grain impurity, which can ensure initial
purification of water.
If some of raw water comes from tap water, chlorine content maybe
is higher. Low-pressure compound RO membrane has strict limitation
to chlorine and organism, which must be ≤ 0.1mg/1.
Because calcium and magnesium content in raw water is very high,
and RO salt-removing rate is about 97%, which may cause deposit of
calcium carbonate, magnesium carbonate, bitter salt, etc. On
concentrated water side. Deposit adhered on RO membrane surface and
may block passage of components and causes pressure difference
increase, water output decrease and salt-removing rate decrease,
which influence normal running and usage span of RO. So before
precision filter, Scale Inhibitor is equipped to protect and avoids
impurity on RO concentrated water side.
2. RO System
RO system is composed of high-pressure pump, RO system and chemical
cleaning device.
During running, RO membrane may form some deposit and chemical
cleaning device is equipped for periodical cleaning to ensure
stable running of RO system. This system configures with Dow's
membrane compounds and Grundfos high-pressure pump.
High-pressure pump is the power source of RO system. To RO system
on sound running condition, high-pressure pump equips inlet/outlet
pressure switch. When inlet pressure is less than set value (water
lack P≤ 0.05Mpa) or outlet pressure is higher than set value,
pressure switch send signal to PLC programming system and
high-pressure pump and RO system will stop in avoidance of
destroying to RO membrane because of water pressure.
RO system pressure control and automatic cleaning are controlled by
PLC. RO system can wash surface of RO membrane by low-pressure
timely and periodically.
