In order to meet the water demand in the production process, many enterprises need to use purified water equipment to make water. When the purified water equipment has been running for a period of time, how should the enterprise do daily maintenance and maintenance to ensure the continuous and stable operation of the equipment and improve the water quality of the equipment?

01

daily maintenance

Regularly clean the dust, oil stains, dirt and other substances on the surface of the purified water equipment to keep the equipment clean.

Check from time to time to check whether the various devices of the water system are in good condition, whether the water supply facilities are unblocked, whether there are loose joints, leaking pipes, etc., and check whether the pump motor is abnormally hot. Relevant personnel of the equipment department conduct a comprehensive inspection of the purified water equipment on a regular, regular and fixed-point basis, especially for some vulnerable parts, find potential faults in advance and deal with them in time.

If the factory cannot troubleshoot and repair the equipment in time, you can contact the manufacturer of purified water equipment for guidance or door-to-door maintenance. After maintenance, the "Maintenance and Maintenance Record of Equipment and Facilities" should be prepared.

02

Replace consumables in time

Consumables such as quartz sand, activated carbon, resin, RO membrane, filter element, etc. are regularly replaced according to the condition of raw water and the preset replacement cycle of the system . According to the use of the equipment, disassemble, clean, repair or replace some parts to ensure that all components of the water system are in good operation and improve the water quality. For example, the filter element of the security filter usually takes1 to 3months to disassemble and wash. If the treatment effect after disassembly and washing is still relatively poor, it is recommended to replace it.

 03

Improve the professional ability of operators

Operators are trained, and they can only take up their posts after passing the examination. On the one hand, operators and maintenance personnel need to pay attention to purified water equipment ideologically, and secondly, they should strictly follow the operation instructions for formal operation in practice, so as to reduce the damage to the purified water equipment caused by human operation errors, or affect the water production of the equipment. water quality.

04

Strictly control various factors to improve water quality

The quality of raw water changes with the seasons, so sampling tests are usually carried out on a quarterly basis, and reports on the quality of raw water are provided. Strictly control the influent water quality to meet the influent requirements, so as not to affect the stable operation of the purification system.

Real-time monitoring of the total water inflow, discharge, temperature, pressure, flow rate and other elements of the purified water equipment ensures that it is within the allowable range of the system, so as not to affect the good performance of the water system.

Every start and stop of the purified water equipment should be flushed, and the operating parameters should be recorded. For long-term shutdown protection and short-term shutdown, effective protection measures need to be taken to prevent the growth of microorganisms and the formation of biofilms that affect the water quality. If a short-term shutdown is required during holidays, the valves ofRO unit andEDIFor purified water equipment that has been shut down for a long time, aCIPcleaning system should be used, and a1%sodium bisulfite solution should be configured. After stirring evenly, add it to theROmembrane shell, and closethe front and rear valves of theRODrain, turn off the main power supply and the main water inlet valve.
