Sewage to purity: the magic of water treatment chemicals

Have you ever wondered how dirty looking sewage can become crystal clear after some treatment? Yes, it's all thanks to water treatment chemicals. These amazing chemicals remove all kinds of pollutants from the water and make the sewage pure.
Common water treatment chemicals


Flocculants: These agents allow small particles in water to aggregate into larger particles, which can then be easily removed through sedimentation or filtration. Aluminium sulphate, iron salts and polymeric aluminium chloride are common flocculants.
Water purifiers: activated carbon is a good example, as it removes odours and organic pollutants from water, leaving it clean and odourless.
Disinfectants: Chlorine, sodium hypochlorite and ozone are disinfectants that kill pathogens and bacteria in the water, ensuring that the treated water is free of disease-causing microorganisms.
pH adjuster: By adjusting the acidity and alkalinity of the sewage, it affects the solubility and sedimentation of certain pollutants, thus improving the precipitation and removal effect.
Corrosion and scale inhibitor: This agent is mainly used to prevent scaling and corrosion of boilers and other circulating water equipment. It prevents scale formation by reacting with calcium and magnesium salts in the water and generating water slag that is precipitated and discharged, thus reducing the concentration of calcium and magnesium ions in the water.
Combination is more effective


In practical application, these agents can be used individually or in combination to achieve better treatment results. For example, the combined use of coagulant PAC and flocculant PAM can efficiently remove suspended and colloidal impurities in water. At the same time, in order to treat the wastewater more pure, it is also necessary to combine with other treatment equipment and technology, such as air flotation machines, filters, oil-water separators, sedimentation tanks and so on.
In short, water treatment chemicals are a powerful assistant in the process of sewage treatment, they can make the sewage become clear and transparent.
