How to maintain purified water equipment on a daily basis?
Purified water equipment generally uses reverse osmosis treatment technology to remove impurities, salts, and heat sources from water bodies, and is widely used in industries such as medicine, hospitals, and biochemical chemical industry.
The core technology of purified water equipment uses new processes such as reverse osmosis and EDI to design a complete set of purified water treatment processes with targeted features. So, how should purified water equipment be maintained and maintained on a daily basis? The following tips may be helpful:
Sand filters and carbon filters should be cleaned at least every 2-3 days. Clean the sand filter first and then the carbon filter. Perform backwash, before forward washing. Quartz sand consumables should be replaced after 3 years, and activated carbon consumables should be replaced after 18 months.
The precision filter only needs to be drained once a week. The PP filter element inside the precision filter should be cleaned once a month. The filter can be disassembled and removed from the shell, rinsed with water, and then reassembled. It is recommended to replace it after about 3 months.
The quartz sand or activated carbon inside the sand filter or carbon filter should be cleaned and replaced every 12 months.
If the equipment is not used for a long time, it is recommended to run at least 2 hours every 2 days. If the equipment is shut down at night, the quartz sand filter and activated carbon filter can be backwashed using tap water as the raw water.
If the gradual reduction of water production by 15% or the gradual decline in water quality exceeds the standard is not caused by temperature and pressure, it means that the reverse osmosis membrane needs to be chemically cleaned.
During operation, various malfunctions may occur due to various reasons. After a problem occurs, check the operation record in detail and analyze the cause of the fault.
Features of purified water equipment:
Simple, reliable, and easy-to-install structure design.
The entire purified water treatment equipment is made of high-quality stainless steel material, which is smooth, without dead angles, and easy to clean. It is resistant to corrosion and rust prevention.
Directly using tap water to produce sterile purified water can completely replace distilled water and double-distilled water.
The core components (reverse osmosis membrane, EDI module, etc.) are imported.
The full automatic operation system (PLC + human-machine interface) can perform efficient automatic washing.
Imported instruments can accurately, continuously analyze, and display water quality.
