The principle of water treatment agents can vary depending on their different types and functions. The following are the working principles of several common water treatment agents:
Hardness regulator: Hardness regulators typically include chelating agents such as EDTA (ethylene diamine tetraacetic acid). These chemicals can combine with calcium and magnesium ions in water to form stable complexes, thereby preventing the precipitation of calcium and magnesium salts and the formation of scales.
Corrosion inhibitors: Corrosion inhibitors typically contain organic substances such as phosphates, oxalates, etc. These chemicals can react with the metal surface to form a protective corrosion inhibitor film to prevent metal corrosion. Corrosion inhibitors can also slow down the rate of metal corrosion by changing the chemical environment of water to make it more alkaline.
Scale inhibitors: Scale inhibitors often contain various additives, such as polymers, dispersants, etc. They can combine with inorganic salts in water to prevent their aggregation and formation of scale, while also dispersing existing scale particles to prevent them from adhering to the surface of the equipment.
Fungicides/disinfectants: Fungicides and disinfectants can kill bacteria, viruses, and other microorganisms in water through oxidation, damage to cell membranes, or inhibition of bacterial metabolism. Common fungicides include chlorides (such as chlorine gas, sodium hypochlorite), ozone, hydrogen peroxide, etc.
Clarifiers: Clarifiers are usually polymer compounds that can adsorb and aggregate suspended and turbid substances in water, forming larger aggregates that are easy to precipitate or filter.
PH regulator: pH regulator can be an acidic or alkaline substance used to adjust the pH of water. They can accept or release hydrogen ions, thereby changing the pH value of water.
It should be noted that different water treatment agents may have multiple complex chemical reactions and mechanisms of action. The correct selection and use of water treatment agents should be based on specific water quality issues and treatment objectives, and follow the guidelines and safety operating procedures provided by the product supplier.
