WZHDN Purified Water Equipment Process Flow:
Raw Water → Raw Water Tank → Raw Water Pump → Multi-Media Filter → Activated Carbon Filter → Water Softener → Safety Filter → First-Level RO System → First-Level RO Water Tank (with pH adjustment device) → Second-Level RO System → Second-Level Purified Water Tank → Purified Water Pump (with ozone sterilization system) → Ultraviolet Sterilization → 0.22μm Microfiltration → Purified Water Use Point Dosing and softening in water treatment systems are two different methods with different purposes and effects. Medication: Medication is a method of changing water quality by adding chemicals to the water. Common chemical treatment methods include chlorination, ozonation, disinfection, etc. These chemicals can be used to kill bacteria, viruses and other microorganisms, remove harmful substances, and improve the taste and smell of water. Dosing treatment is mainly used for water disinfection and purification to ensure water safety and hygiene standards.
Softening treatment: Softening treatment is a method of removing hardness from water. It mainly reduces the hardness of water by removing calcium and magnesium ions in the water. Hardness refers to the concentration of calcium, magnesium and other metal ions contained in water. Water with high hardness is prone to scale during use, affecting water quality and the service life of equipment. Commonly used meth ods for softening treatment include ion exchange, reverse osmosis, etc. Softening treatment can make water more suitable for industrial production, household use and equipment protection.To sum up, chemical treatment is mainly used to disinfect and purify water, remove harmful substances in water, and improve the safety and hygiene standards of water quality; while softening treatment is mainly used to remove hardness in water, reduce the generation of scale, and improve the suitability of water quality.
