• The process of removing the undesirable impurities which includes chemicals, biological contaminants, suspended solids and gases from water is called water purification. Water purification may reduce the concentration of particulate matter including suspended particles, parasites, bacteria, algae, viruses and fungi as well as reduce the range of dissolved and particulate matter. Domestic water has its applications in every person’s normal life like drinking water, cooking, bathing, cleaning, gardening, swimming pools, washing etc. Hence the purification of domestic water is important and can be carried out in different ways. Domestic water can be treated physically by performing settling and filtration process, chemically by disinfection and biologically by performing sand filtration. The standards for drinking water quality are generally set by the Government or by International standards. These standards include minimum and maximum concentrations of contaminants, depending on the intended use of the water.

    A Domestic water purifier is required for removing heavy metals, iron, magnesium and other harmful elements and impurities to make sure the water is fit for consumption or use without any short or long term risk to health. There are different ways of purifying domestic water and some of them are Sediment Filtration, Activated Carbon Black (ACB) Filtration, Granular Activated Carbon (GAC) Filtration, Reverse Osmosis (RO) Filtration, Distillation, Ion-Exchange (IX), Ultraviolet (UV) Disinfection, and Ultrafiltration (UF), Activated Alumina (AA) Filtration and Ionization.

  • Ion-Exchange Water Purifiers

    The process of removing the undesirable dissolved ions from the water and replacing it with the other ions of same electrical charge from the ion exchange resin is called ion-exchange water purification system. Here the chemical reaction takes place when the water is made to pass through the ion-exchange vessel with the specialized resin either in batches or in a continuous mode. The ion-exchange process is of two types - cation ion-exchange process for the positively charged ions and anion ion-exchange process for the negatively charged ions. These two process are used in water softening and deionization purposes like demineralization, acid absorption and heavy metal removal.

  • Sediment Filtration

    Sediment filtration is the common and basic water filtration system widely used across the world for domestic, commercial and industrial water treatment. It is mainly used for removing the sediments like rust, sand, dust, slit, heavy metals and other large particles from the water. Sediment filter can independently be used as a point of entry (POE) in whole house filtration solution or can also be used in conjunction with other filters to provide greater filtration. For domestic use, the sediment filters are mainly used as a pre-filter in other water filtration system at home like Activated Carbon Filter and Reverse Osmosis for preventing the large particles getting clogged in rest filters. Anyhow, the sediment filters cannot remove chemicals and contaminants which are smaller than 1 micron.

  • Distillation

    Distillation water purification systems are in use since a very long time. Here, the water distiller first evaporates the water by heating it to its boiling point using electrical energy, then the steam is captured and condensed into pure distilled water in a liquid form. When the impure water is vaporized and condensed, the contaminants in water including essential minerals are left behind and gets discarded later. The Volatile Organic compounds do not get distilled in this process because they will get vaporized and condensed into the distilled water as their boiling points are less than 100 degree Celsius. The application of distillation water filtration is quite limited as it is a time taking process, but are strong purification system.
