Common problems with water treatment equipment:
I. Equipment operation problems:
1. The effluent from the clarifier is turbid during operation. What is the reason and how to deal with it? The reasons may be: too little dosage or the pump does not apply the medicine; the raw water flow and temperature change dramatically; the raw water flow is too large; the sludge layer is too high or too low; the outlet pipe is blocked; the agitator is abnormal, etc.
Treatment measures: adjust the flow and temperature to make it stable; appropriately increase the medicine tray or check the medicine pump for medicine application. If the medicine is not applied, contact maintenance in time; adjust the raw water flow; increase the sewage discharge and reduce the height of the sediment layer; flush the outlet pipe; check and adjust the agitator speed, or contact maintenance for treatment
2. The effluent flow of the clarifier becomes smaller and does not reach the rated value. What should I do? The reasons may be: the water outlet of the pool is not smooth and is blocked by dirt; the water pressure becomes low
Treatment measures: remove the dirt at the outlet; contact the value manager to increase the water pressure
3. The high-pressure pump does not start and cannot make water. How to check? You can check whether there is a power outage and whether the plug is properly plugged in; check whether the low-voltage switch fails and cannot be connected to the power supply; check whether the water pump and transformer are short-circuited, or the whole machine line is connected incorrectly; check whether the high-voltage switch or water level controller fails and cannot be reset; check whether the PLC is faulty
4. The high-pressure pump works normally, but cannot make water. What is the reason? It may be: the high-pressure pump loses pressure; the water inlet solenoid valve fails and cannot enter water; the pre-filter is blocked; the check valve fails; the automatic flushing solenoid valve fails and cannot be effectively closed; the PLC fails and cannot close the recoil solenoid valve; the RO membrane is blocked [
II. Equipment maintenance issues:
1. What should I do if the equipment is blocked? You can regularly check and clean the inside of the equipment to ensure that impurities do not accumulate; use filters or screens to intercept large particles to reduce the possibility of blockage; regularly perform equipment maintenance to ensure that the equipment is in the best working condition
2. How to deal with water quality problems or equipment damage caused by improper use of chemicals? Select appropriate chemical agents according to water quality and treatment requirements; strictly follow the instructions or expert recommendations to add agents to avoid overdosing or underdosing; regularly test water quality to ensure that water quality meets standards [
3. What to do if equipment is aging? Regularly inspect and maintain the equipment to promptly discover and deal with potential problems; promptly replace severely worn parts to ensure equipment performance; regularly maintain the equipment to extend its service life
4. How to solve the problem of filter element blockage? The filter element is one of the core components of pure water equipment. If the filter element is not replaced or cleaned for a long time, it is easy to be blocked by impurities, microorganisms, etc. When it is found that the water output of the pure water equipment is reduced or the water quality of the water output is reduced, the filter element should be checked and replaced or cleaned in time. At the same time, it is also important to regularly maintain and maintain the filter element
III. Water quality related issues:
1. After multiple regenerations of anion and cation resins, the pure water obtained still does not meet the standards. What is the reason? It may be: the resin is no longer effective. The best service life of domestic resin is generally one year. Beyond this period, the regeneration cycle of the resin will be significantly shortened, eventually leading to its failure; resin poisoning, which usually occurs when the water quality is extremely poor, especially when the water supply is groundwater, the resin will be affected by iron poisoning; the water quality of the water supply has deteriorated, and the purification effect of the resin is closely related to the process, resin quality, and water source quality; the resin regeneration method is improper or the chemical agent used has problems
2. Can water treated with reverse osmosis be used as boiler feed water? Yes, reverse osmosis technology removes dissolved salts, colloids, microorganisms, organic matter, etc. in water through pressure difference, and boiler feed water mainly requires water hardness. Reverse osmosis can effectively reduce water hardness
3. What aspects should be paid attention to when restarting reverse osmosis water treatment equipment
