1TPH RO Filter Plant Water Treatment System FRP Nitrate Removal Machine
Preparation before operation of reverse osmosis water treatment equipment:
RO as a high pressure operation equipment, before operation, in order to protect the equipment and instrument and safety, it is necessary to confirm and adjust the opening state of the valve strictly in accordance with the operating procedures. The specific operations are as follows:
1. Completely open the water inlet valve of the security filter and open the water inlet valve of the high pressure pump
2. Open the high-pressure pump outlet valve for a circle
3. Open the RO inlet valve for one turn
4. Rotate the needle valve on the concentrated water pipe three and a half turns
5, fully open the water production outlet valve and concentrated water outlet valve
6. Close all sampling valves and cleaning valves
7. Open all pressure display valves to half open state
Components and Principles of RO Water Treatment System
The reverse osmosis system includes high pressure pump, reverse osmosis membrane element, pressure vessel (membrane shell), cleaning system and control instrument; the principle of reverse osmosis water treatment system is: when a pressure greater than osmotic pressure is applied on the brine side of the membrane, the water The direction of flow will be reversed, and the water in the brine will flow into the fresh water side, a phenomenon called reverse osmosis.

Pretreatment dosing problem of reverse osmosis water treatment system:
1. Dosing problems of flocculant and coagulant aid:
The turbidity of the source water, PH value, the content of iron ion and the type of drug added in the subsequent system determine the type and dosage of the flocculant and coagulant aid. And dosage must do adaptability and dosage optimization test. Many RO users in this aspect of the work is not in place, resulting in the clarification of the pool water quality is not good.
2. The dosing problem of fungicides
For organic matter and bacteria and microorganisms in raw water, the user usually uses oxidizing media to kill, such as sodium hypochlorite, liquid chlorine, chlorine dioxide, etc. For some surface water sources, the bactericidal effect is not ideal due to the long-term addition of the above medium. At present, non-oxidizing fungicides, such as ZDH-881 and MDC-881, have longer killing effect, and can save the cost of subsequent reducing agent addition.
3. The addition of reducing agent
The addition of reducing agent should take into account the thoroughness of the reduction effect and the bacterial contamination after excessive addition. It is often found that after the user adds too much, the bacterial slime on the filter element is generated.
Process flow of RO Water Treatment System
Original water pump → mechanical filter (quartz sand filter)→ activated carbon filter → sodium ion exchanger (water softener)→ security filter → high pressure pump → reverse osmosis → ozone sterilizer (ultraviolet sterilizer)
