What is difference between water treatment and water purification system？

Global water resources are facing unprecedented challenges. Industrial wastewater, agricultural non-point source pollution, and domestic sewage contain suspended particles, organic pollutants, bacteria, viruses, and other harmful substances in water sources; Definition of Water Control and Water Purification System

What is Water Treatment?

Water treatment is a broad concept that refers to the entire process of physically, chemically, or biologically treating raw water (including river water, seawater, and even wastewater) to make it suitable for specific purposes; It not only covers the preparation of drinking water, but also encompasses multiple fields such as industrial water treatment, sewage treatment, and recycled water preparation!

The focus of the water treatment system is to degrade water quality to meet the diverse needs of different uses; Municipal water treatment mainly ensures the safety of drinking water. Industrial water treatmenr can focus on preventing equipment scaling or corrosion! And wastewater treatment focuses on pollutant removal and minimizing environmental impact.

What is the function of water purification system?

In contrast, the scope of water purification systems is more focused, typically referring to equipment and systems used to improve the quality of drinking water! Water purification systems typically treat water that has undergone preliminary treatment (such as municipal tap water), further removing residual impurities through multi-stage filtration, and providing safe water for direct drinking;

Household and commercial water purification systems are usually small-scale terminal settings, whose main function is to ensure the safety and taste of drinking water. The whole house clean water system has expanded its scope of management to include components such as pre filters, central water purifiers, water softeners, and end of pipe direct drinking machines. The opposite of technical principles and process flow

How does water treatment system work?

The water treatment adopts a multi skill integrated process route, which is comprehensively managed based on the requirements of raw water quality and target water quality, combined with physical, chemical, and biological methods;

The physical processing ability mainly includes sedimentation, which deceives the function of gravity to cause suspended particles in water to settle and distinguish! Filtering is the process of intercepting impurities through sand filtration, multi-media filter towers, etc; Air flotation is the use of bubbles to lift and remove lightweight particles.

Chemical treatment technology includes coagulation/flocculation, which aggregates and settles fine particles by adding chemicals. Disinfection is achieved through chlorination, ozone or ultraviolet radiation sterilization; PH adjustment is achieved by adding acid and alkali to optimize water quality!

Biological treatment technology mainly utilizes microorganisms to degrade organic pollutants in water, including activated sludge process and biofilm process. These skills are particularly applicable to sewage treatment and organic pollution, which are the primary sources of water;

Large scale water treatment systems usually combine multiple processes to create a complete management process! Municipal water plants often use the classic process of “coagulation+sedimentation+filtration+disinfection” to ensure stable water quality!

How does water purification system work?

The water purification system mainly adopts multi-stage filtration technology, which removes pollutants from water step by step through filter elements of different accuracies. The core technology is mainly based on physical filtration, supplemented by chemical control;

Pre filtration is the first line of defense in water purification systems, mainly removing large particles such as sediment and rust from water through PP cotton filters or pre filters. The filtration accuracy is usually between 1-100 microns, and its main function is to protect subsequent filter elements and settings;

Core filtration process  incorporates activated carbon adsorption and membrane separation technology! Activated carbon filter can effectively adsorb residual chlorine and organic compounds in water; Membrane separation technology, on the other hand, incorporates ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO) to remove smaller pollutants such as heavy metals, viruses, and dissolved solids.

The final control mainly includes UV sterilization and ozone disinfection to ensure the stability of microbial targets in water; This stage is particularly important for people with weaker immune systems!

Modern clean water systems have developed intelligent functions such as filter life monitoring, real-time water quality display, and automatic cleaning, greatly improving application convenience and safety.
