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.

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.

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).

The goal of a water treatment plant is to comprehensively remove various pollutants in water, including organic matter, inorganic matter, heavy metals and pathogenic microorganisms. The goal of a water filtration plant is mainly to remove suspended matter and impurities in water.

The main types of water treatment plants are: 1. Drinking water treatment plants, 2. Sewage treatment plants, 3. Industrial water treatment plants, 4. Seawater desalination plants.
