Iron Removal Plants are water treatment facilities designed to remove iron and other impurities from water.Iron reduction processes can be divided roughly into two categories: gas-based, and coal-based. In both cases, the objective of the process is to remove the oxygen contained in various forms of water.
The domestic iron removal plant is the filtration unit. Basundhara Engineering is a Kolkata-based company that is well-trusted by customers and manufactures, supplies, exports, and provides services for Domestic Iron Removal Plants across India
During the aeration process, the dissolved ferrous iron reacts with the oxygen from the air. This reaction converts the ferrous iron into ferric iron, which is insoluble in water. The oxidation of iron is a chemically facilitated process that occurs due to the interaction between ferrous iron, oxygen, and the presence of a catalyst. In some cases, additional catalysts such as manganese dioxide or activated carbon may be added to the water to enhance the oxidation process.
The newly formed ferric iron precipitates out of the water as rust particles or iron floc. The size and density of the iron floc depend on various factors such as the concentration of iron, pH, temperature, and the presence of other substances in the water. The iron floc can be visible as brownish or reddish particles.
It’s important to note that the intensity of the yellow or brown color in iron water can vary depending on the concentration of iron, the oxidation rate, and the presence of other substances. Factors such as pH, temperature, and the presence of dissolved organic matter or minerals can influence the color of iron water as well.
The process of iron removal in a water treatment plant aims to oxidize and precipitate the dissolved ferrous iron, followed by the removal of the resulting iron particles through settling and filtration steps. This helps improve the visual appearance and taste of the water, as well as prevents the formation of rust deposits or stains in plumbing fixtures and appliances.
