Water treatment application project

Water Treatment Application projects are a broad and diverse field that aims to remove impurities, pollutants and harmful substances from water through physical, chemical or biological methods to improve water quality and meet a variety of water needs. Below are some of the main water treatment applications and their detailed descriptions:

First, drinking water treatment

Objective: To ensure the safety of drinking water, remove suspended solids, bacteria, viruses, heavy metals and other harmful substances in water.

Application scenarios: residential areas, schools, hospitals, hotels, villas, airports, living areas, etc.

Treatment process: including coagulation, precipitation, filtration, disinfection (such as chlorine disinfection, ozone disinfection, ultraviolet disinfection) and other steps. For water sources with poor water quality, advanced treatment technologies such as reverse osmosis and ultrafiltration may also be needed.

Second, industrial water treatment

Objective: To meet the high requirements of water quality in industrial production, such as ultra-pure water in electronic industry, water in pharmaceutical industry, water for industrial product manufacturing, etc.

Application scenario:

Electronics industry: Ultra-pure water is needed in the production process of monocrystalline silicon semiconductors, integrated circuit blocks, liquid crystal displays, etc.

Pharmaceutical industry: pharmaceutical preparations, large infusion, natural substance extraction, traditional Chinese medicine drinks and other production water.

Industrial product manufacturing: automobile, electroplating, painting, coating, paint, fine processing, cleaning, etc.

Treatment process: Depending on the specific needs, it may include pretreatment (such as softening, iron and manganese removal), reverse osmosis, ultrafiltration, EDI (electric deionization) and other technologies.

Third, sewage treatment and reuse

Objective: To treat industrial wastewater and domestic sewage to meet discharge standards or reuse water quality requirements, so as to realize the recycling of water resources.

Application scenarios: industrial sewage, recycled water, domestic sewage, car cleaning, etc.

Treatment process: including physical treatment (such as grid, precipitation), biological treatment (such as activated sludge method, biofilm method), chemical treatment (such as coagulation, precipitation, oxidation) and deep treatment (such as reverse osmosis, ultrafiltration).

Fourth, seawater desalination and brackish water treatment

Objective: To convert seawater or brackish water into fresh water for human use and solve the problem of water shortage.

Application scenarios: Preparation of islands, ships and drinking water in saline-alkali areas.

Treatment process: mainly includes distillation, reverse osmosis, electrodialysis and so on. Among them, reverse osmosis is widely used because of its advantages of low energy consumption and simple operation.

Five, agricultural irrigation water treatment

Objective: To remove harmful substances and impurities in irrigation water and ensure clean water resources for crops.

Application scenario: agricultural irrigation system.

Treatment process: Depending on the water quality, it may include simple treatment such as filtration, disinfection, or more advanced treatment technology such as reverse osmosis.

Six, swimming pool and spa water treatment

Objective: To remove the pollutants and bacteria in the water, maintain the water clear and clear, and ensure the health and safety of tourists.

Application scenarios: indoor swimming pool, outdoor landscape pool, spa, etc.

Treatment process: including coagulation, precipitation, filtration, disinfection (such as chlorine disinfection, ozone disinfection) and other steps. At the same time, the pool water should be changed regularly and the water quality should be monitored.

7. Other special purpose water treatment

Objective: To meet the special requirements of water quality in specific industries or scenarios.

Application scenarios: such as artificial aquaculture water (fish and shrimp aquaculture, ornamental fish, etc.), circulating cooling water (central air conditioning, smelting, water-cooled air conditioning, etc.), fine chemical water (cosmetics, detergents, biological engineering, genetic engineering, etc.), etc.

Treatment process: According to the specific needs of the corresponding treatment technology, such as softening, desalting, ultrafiltration, reverse osmosis and so on.
