Introducing SDI with double power of softening and purification


Our patented technology of capacitive deionization works when electricity is applied to the electrode, ions of opposite charge pass through the ion exchange electrode and move to the surface of the electrode and are electrically adsorbed




When the water source is groundwater, river water, or municipal water, SDI is the most cost-effective and energy-efficient method of purifying water. SDI removes the dissolved charged species such as total dissolved solids (TDS), inorganic contaminants, and radionuclides.

Capacitive Deionization (SDI) vs. Reverse Osmosis (RO)

  • SDI has an 80% water recovery when purifying to drinking water quality. RO has a 30% water recovery.

  • SDI costs approximately ₹8 per 1000 litres. RO costs ₹15 to ₹25 per 1000 litres.

  • SDI does not require water softening prior to purification. RO does require water softening prior to purification.

  • SDI is a low maintenance system. RO is a high-pressure system across membranes requiring routine maintenance.

  • SDI is capable of leaving some minerals in the water. RO removes everything, including good minerals.



  • Up to four cells can be configured in series, applicable to a wide range of TDS

  • Operation under stable DC voltage by using bipolar electrode (300VDC or less)

  • High recovery rate, up to 80%

  • Salt removal rate up to 80%

  • Operating temperature, max. 60℃

  • Low energy consumption due to low voltage operation

  • Electrode is not exposed to ensure electrical safety

  • Compared with other processes, the pretreatment conditions are simple and the pretreatment process cost is economical.



  • SDI Point-of-Entry System (Whole house water purifier):​


Our patented SDI water purification technology provides a method to treat inlet water coming into your house from various sources like borewells or municipal pipelines.

The SDI system works as both a softener and water purifier.

Regular softeners require frequent regeneration, and when doing so release chemicals into the water table. This damages the environment causes corrosion in pipelines, and damages appliances.

SDI technology provides a water softening solution that is both environment-friendly and chemical-free.

You will not need water softeners or RO systems that require regular recharging and have a negative environmental impact like high wastage of water during purification.

Also, RO removes all minerals from the water which are beneficial for the human body. With SDI, the owner can decide to choose the mineral level (TDS) with the click of a button.

  • Commercial and Industrial SDI Water Purification:


SDI technology is used in many types of commercial applications, such as drinking water vending machines, water ATMs, rural water purification, centralized clean and safe drinking water for schools, colleges, hospitals, railway stations, big offices, laundry, agriculture, boiler industry, wastewater treatment.

The trusted water treatment systems offered by us consist of fully automatic self-cleaning ensuring the output water produced is clean and high quality, adjusting to varying TDS of inlet water.

SDI technology is used in many types of industrial applications, such as beverage manufacturers, the automotive industry, sewage treatment plants, breweries, and cooling towers.

SDI is capable of removing the following:

  • Total Dissolved Solids (TDS), principally calcium, magnesium, potassium, sodium, bicarbonates, chlorides, and sulfates.

  • Inorganic contaminants such as antimony, arsenic, barium, beryllium, cadmium, chromium, copper, cyanide, fluoride, lead, mercury, nitrate, nitrite, perchlorate, selenium, and thallium.

  • Radionuclides such as alpha and beta particles, radium, and uranium.

  • Disinfection byproducts such as bromate and chlorite.

  • Ammonia, nitrites, and nitrates.

  • Organic contaminants dissolved in an aqueous solution as a charged species.
