Product Description

RO-2-10 2-stage RO Water Treatment System

Capacity: 10, 000L/hr


2-stage 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.

Composition of Water Treatment System

1. Pre-treatment System.

Pre-treatment system is composed of mechanical filter, active carbon filter, softener 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 influences 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, 2-stage RO system and chemical cleaning device.

2-stage RO system can remove salt over 99% and 100% organisms. 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 Hydranautics ESPA1 membrane compounds (USA) and Grundfos high-pressure pump (Denmark).

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.

This water treatment capacity is 10 m3/h. Salt-removing rate is over 99.0% and water recycling rate is 75%.
