The production process of purified water equipment
Raw water automatic water inlet motorized control valves - raw water buffer box - raw water booster pump - multi-media filters
-- Activated carbon filter -- Precision filter -- Scale inhibitor and dosing device -- First-stage High-pressure pump - a reverse osmosis device - PH adjustment device - the second high-pressure - the second reverse osmosis device
- purified water production tank - ultraviolet sterilization device - purified water supply distribution system - water point. -Water point.
Raw water quality requirements for purified water equipment
Often analyze the quality of raw water, observe the changes in water quality, to see whether the RO membrane feed water quality meets the target. Water quality exceeds the standard on reverse osmosis is far-reaching. Water quality exceeds the standard, there must be a suitable reverse osmosis treatment process to deal with, to achieve the RO membrane feed water indicators, so we are now selected reverse osmosis treatment process is adapted to the current raw water quality standards, it is necessary to analyze the quality of the raw water from time to time, timely problems in a timely manner. Therefore, the raw water quality changes directly related to the normal operation of reverse osmosis.
Purified water reverse osmosis RO membrane maintenance
? Reverse osmosis operating system downtime for two days, should be started once, in order to prevent bacterial contamination caused by RO membrane. Downtime is too long generally to add bacteriostatic agent, winter to prevent freezing. Otherwise it will cause permanent damage to the filter membrane.
? How to start the reverse osmosis operating system Note: Before starting the equipment, you should ensure that the RO feed water in line with the parameters described in the "RO feed conditions" section, otherwise it will cause permanent and irreversible damage to the reverse osmosis membrane element.
1, first open the raw water supply source valve.
2, if the equipment is the first time to start running, you should open the sewage outlet before the security filter, and after observing and determining the cleanliness of the raw water, close the sewage outlet, so that the raw water enters the security filter.
3. Open the thick water adjustment valve and adjust the throttle valve after the pump to a moderate state. Equipment equipped with cleaning port and cleaning valve, should first check whether the valves are in the open or closed state as required.
4, to be a precision filter after filtering pressure gauge rose 0.05Mpa, start the host power switch.
5, the equipment will start working according to the principle of reverse osmosis system host action (see "reverse osmosis system host action principle").
6, the host operation, gradually open the pump throttle valve, adjust the thick water adjustment valve, so that the ratio of pure water and thick water to reach the rated target, and then adjust the pump throttle valve, so that the pure water production to reach the rated target.
7, this equipment has raw water low pressure protection function. When the raw water supply is insufficient, the pressure drops to a certain value, the pressure switch will automatically shut down the RO system to protect the high-pressure pump. When the raw water pressure is restored, the equipment automatically resume work. After the automatic shutdown or restoration of the equipment to start, the operator should adjust the operating parameters of the equipment in a timely manner.
8, at any time, do not completely close the thick water adjustment valve, otherwise it will make the system pressure suddenly rise, resulting in equipment damage or endanger the safety of the operator.
9, it is recommended that the user to establish the equipment operating records, please call for details.
10, the first use of equipment, the purified water should be discharged at least one hour before collection and use.
