Adsorption refers to the process by which one substance attaches to the surface of another substance. Specifically, adsorption uses the surface of porous materials to attract and fix pollutants in water on its surface, thereby separating these pollutants from the water body.

As a key indicator, TKN plays a vital role in the wastewater treatment process. It not only helps determine the degree of wastewater pollution, but also directly affects the process selection and management strategy of wastewater treatment.

The water quality standards used in agricultural irrigation are different from those for drinking water. Generally speaking, agricultural irrigation water does not need to meet the high standards of drinking water, but it must meet the growth needs of crops and cannot cause adverse effects on soil and plants.

Sewage treatment plants mainly treat seriously polluted domestic sewage and industrial wastewater, with complex processes and large environmental impacts, while gray water treatment plants focus on treating less polluted gray water, with relatively simple processes and small environmental impacts.

Generally speaking, a water treatment plant with a treatment capacity of more than 100,000 cubic meters/day is usually considered a large water treatment plant. This standard varies depending on the region and water treatment needs.

At present, the coagulants used in the market are mainly divided into three categories: inorganic coagulants, organic coagulants and polymer coagulants. Each type of coagulant has its own unique chemical properties and application scenarios.

A 3000 L/h water treatment plant is moderately sized and suitable for the water supply needs of small and medium-sized industrial users, small communities or large buildings.

Differences in working principles ● Reverse osmosis relies on physical separation, separating water molecules under pressure through a semipermeable membrane. ● Distillation is based on phase change, separating impurities in water through heating and condensation processes.

Ultraviolet disinfection technology is widely used in water treatment, mainly including drinking water treatment, sewage treatment, industrial wastewater treatment, aquaculture and swimming pool disinfection.

The top five famous water treatment plants: 1. Tokyo Water Treatment Plant (Japan), 2. Singapore NEWater Plant (Singapore), 3. London Thames Water Treatment Plant (UK), 4. New York Brooklyn Water Treatment Plant (USA), 5. Abu Dhabi Sulaibiya Water Treatment Plant (UAE).
