Water Softening

Softening is the removal of multivalent cations (hardness) in the water.
Application of Water Softening in our solutions

Membrane processes with pore sizes in the nanofiltration range are being used for softening

Ion exchange can be used to remove hardness ions (multivalent cations), nitrates, or other inorganic constituents

Multimedia Filter (MMF)

Multi-media Filter (MMF) contains three layers of media consisting of anthracite, sand and garnet. These layers of media carry out the filtration and are chosen due to the differences in their size and density.
  • Anthracite is layered at the top due to having the lowest density and largest particle size;
  • Sand is layered in the middle, having intermediate density and particle size; and
  • Garnet is layered at the bottom, with the highest density and smallest particle size.
This way, the entire bed acts as a filter with each layer removing pollutants of different size ranges.

Water Disinfection

Disinfection is the process designed to kill most microorganisms in wastewater, including essentially all pathogenic (disease causing) bacteria.
Application of Water Disinfection in our solutions

Water completely free of suspended sediment, is treated with a powerful oxidizing agent, usually chlorine, chlorine and ammonia (chloramine), or ozone

The other commonly used method of disinfection is ultraviolet light (UV)

Activated Carbon Filtration (ACF)

Activated Carbon Filter (ACF) is a type of filtration technology that uses activated carbon to remove Total Organic Carbon (TOC), odor, color and Chlorine from the fluid by adsorption. The treated water is free from chloramines (chlorine and ammonia mixture) and organic compounds. Due to the highly porous nature of the carbon granules, the media provides a large surface area for capturing the contaminants.

Commonly used in water treatment plants after multi-media filters or other conventional filtration processes

NanoFiltration (NF)

Nanofiltration (NF) is a type of membrane filtration technology that removes contaminants using a semi-permeable membrane. Nanofiltration is similar to Reverse Osmosis in terms of the contaminants removed, but unlike RO, it does not effectively filter monovalent ions like Chlorine. NF membranes can filter particles in the range of 0.001 to 0.01 micron. Nanofiltration is used for removing specific heavy metals, reducing salt content of brackish water and for water softening.

Ultrafiltration (UF)

Ultrafiltration (UF) is a type of membrane filtration technology that uses a semi-permeable membrane to filter suspended solids and microorganisms from water. UF membranes can filter particles in the range of 0.01 to 0.1 micron.. Due to the smaller pore size compared to MF, a higher operating pressure is required to push the water through a UF membrane.

Commonly used as a pretreatment to Reverse Osmosis (RO)

MicroFiltration (MF)

Microfiltration (MF) is a type of membrane filtration technology that passes contaminated liquid through a semipermeable membrane to filter suspended solids and microorganisms from water. MF membranes can filter particles in the range of 0.1 to 1 micron, which include particles such as sediment, algae, protozoa or large bacteria.

Reverse Osmosis (RO)

Reverse Osmosis (RO) is a technology used to produce high-quality demineralized water. In reverse osmosis, pure water is produced by pushing the contaminated water through a semipermeable membrane using external pressure. RO membranes can filter particles in the range of 0.0001 to 0.001 microns. The membrane traps upto 99% of dissolved and suspended contaminants while allowing pure water to flow through it.
