The following is a detailed introduction of common water treatment agents and functions:
Flocculant: It is used to remove suspended solids in water. The flocculant has a chemical reaction through the electrical part of the surface of the suspended particles, which condenses the particles into a larger group, which is convenient for subsequent precipitation or filtering. Common flocculants include aluminum salt (such as aluminum sulfate) and iron salt (such as polymer iron chloride).
Flocker: combined with flocculant to enhance the flocculation effect. The flocculator will change the nature of the suspension in the water and make it easier to condense. For example, polymer silicate is a common flocculant, which can accelerate the reaction of flocculant and suspension, and form larger flocculation.
Activated carbon absorbing agent: used to remove organic matter in water. Activated carbon has a highly high pore structure and adsorption capacity, which can absorb organic molecules, odor substances and pigments in water. It is widely used in the fields of drinking water treatment, wastewater treatment and air purification.
Ion switch: used to remove ions in water. Ion exchanges are a solid material that have the ability to selectively adsorb and release specific ions. Common ion exchanges include strong acid -type resin and strong alkaline resin, which can be used to remove cations and anion in water.
Chelatox: It is used to form a stable complex with metal ions. The chelating agent can form complexing with metal ions in the water to avoid the precipitation and deposition of metal ions. Common chelated agents include EDTA (ethyleine tetharine) and DTPA (diocyl tatamine).
Oxidant: For organic matter and microorganisms in oxide. Oxidants such as chlorine dioxide and hydrogen peroxide can oxidize and decompose the organic matter in water, killing bacteria, viruses and other microorganisms in water.
Salvas: Used to control the formation of stain accumulation. Salvas can reduce the sedimentation of calcium and magnesium in water, such as calcium and magnesium, and prevent stains from blocking and damage to the equipment. Common dirt resistant agents include polyphospholtic acid, polycarboxylic acid, etc.
Preservation: It is used to prevent metal corrosion in water. Proclaima can form a protective film, blocking metal contact with water, and reducing the occurrence of corrosion. Common preservatives include nitrite, nitrate and organic corrosion agent.
The specific dosage, usage method and precautions of each water treatment agent must be determined according to the actual situation and manufacturer suggestions. When selecting and using water treatment agents, make sure to follow relevant safety operating procedures and regulations, and continuously monitor and maintain the water quality of the water treatment system.
