Water Treatment Chemicals

There are many Bisley Chemicals that can be used to chemically treat water.

Here are the different water treatment chemicals.

Algaecides

Algaecides, which are chemicals that kill and/or blue or green algae when added to water, are chemicals. copper sodium sulphate and iron chloride are some examples. Algaecides work well against algae, but they aren’t very useful for algal blooms.

The problem with most algicides is that they kill all existing algae but do not remove the toxins that the algae release before it dies.

Corrosion inhibitors

Corrosion refers to the process of converting metal into an insoluble compound.

Corrosive inhibitors are frequently used. Inhibitors react with metallic surfaces and provide some protection. Inhibitors can be found on metallic surfaces by adhering to them, protecting them with a layer.

There are five kinds of corrosion inhibitors. These are:

  • Passivity inhibitors or passivation.These inhibit the corrosion potential and force the metallic surface to the passive range. Passivity inhibitors can be oxidizing and non-oxidizing anions (e.g. nitrite, chromate, and nitrate), as well as oxidizing and nitrate anions. These inhibitors have the highest effectiveness and are therefore the most commonly used.
  • Cathodic inhibitors.Some cathodic inhibitors, like compounds of arsenic, antimony, and zinc, make it harder for hydrogen to be recombined and released.
  • Organic inhibitorsWhen present in sufficient concentrations, can be harmful to the entire surface of corroding metals. Hydrophobic films are formed on the metal’s surface by organic inhibitors.
  • Precipitation inhibiting inhibitors.These compounds are responsible for the formation of precipitates on metal surfaces, which provides a protective layer. These are silicates, phosphates, and the most frequent inhibitors.
  • Volatile Corrosion Inhibitors (VCI).These are compounds that are transported in a closed environment to the spot of corrosion by volatilization.These salts’ vapor condenses upon contact with metal surfaces and is hydrolyzed using moisture to release protective ions.

Neutralizing agents (alkalinity controls)

To neutralize acids and basic, we use salt hydroxide solution(NaOH), Calcium corate (Ca(OH), 2) to raise pH levels. To decrease pH levels, you can use either diluted sulfuric acid (H 2SO 4) or diluted hydrochloric acids (HCl). The pH of water in a reaction basin will determine the amount of neutralizing agents. The temperature rises due to neutralization reactions.

Oxygen scavengers

Oxygen scavenging refers to preventing oxygen oxidation reactions from occurring. Many organic compounds that are naturally found have a slightly negative charge. These organics can absorb oxygen molecules. They also have a slight positive charge to prevent oxidation reactions from occurring in water.

Many salts contain catalyzing substances to speed up the reaction with dissolved oxygen.

Scale inhibitors

Scale is the precipitate that forms on surfaces when they come into contact with water. It’s formed by the precipitation of normally soluble solids, which become insoluble with increasing temperature. Scale can be caused by calcium carbonate or calcium sulphate.

Scale inhibitors are negatively charged surface-active polymers. When minerals surpass their solubility and start to combine, the polymers are attached. The structure necessary for crystallization is broken down and the formation scale is prevented. The inhibitor is combined with the scale particles are dispersed and will remain in suspension.

Phosphate esters, phosphoric Acid, and solutions of low molecular weight polyacrylic acid are examples of scale inhibitors.
