Water Softener

Water Softener

At AFI Pure Projects, our "AFI-EDI" brand Electro-Deionization (EDI) systems present a compelling alternative to mixed-bed or twin-bed ion exchange systems. When combined with our "AFI-RO" ultrapure double pass RO system as a pretreatment, the "AFI-EDI" system delivers 16-18 mega-ohm permeates water without the need for regeneration chemicals. This makes it an attractive choice for industries such as Electronics, Semiconductors, and pharmaceuticals, where high-purity water is essential.

What is a Water Softening Plant?

A water-softening plant treats hard water with sodium chloride, commonly known as salt. Hard water contains an excess of minerals such as calcium, magnesium, manganese, and iron, which can cause issues in households. These minerals crystallize and adhere to domestic surfaces as the water is heated. A water softener, with sodium chloride, helps replace these undesirable minerals.

The water softening process involves passing the water supply through resin beds in the water softener. Rows of resin beads perform ion exchange, attracting and exchanging undesirable 'hard' mineral ions for sodium ions. Sodium chloride is the most common type of softener resin used for this purpose.

Water Softening Benefits:

Water softening is essential as it reduces the hardness of water in homes and businesses. Hard water can clog pipes and slow down soap dissolution. Water softening prevents these negative effects, ensuring smooth functioning of water systems and extending the life of appliances.

Types of Water Softeners:
  • Lime Treatment
  • Ion Exchange Resin-Based Softeners
  • Nanofiltration
  • Reverse Osmosis

Aqua Filsep Inc. specializes in ion exchange resin-based water softeners. These softeners effectively remove hardness minerals like calcium and magnesium, ensuring soft water without the formation of hard scales.

Our Softener Products:
  • AFI-Softener – PS (Package Softeners): Designed for counter-current regeneration systems, these compact softeners have flow rates ranging from 1 to 14 m3/hr. Built with Fiber Reinforced Plastic (FRP) and sturdy multiport valves, they offer simple operation and control.
  • AFI-Softener – IS (Industrial Softener): Ideal for extended working cycles and minimal regeneration costs, these softeners use counter-current flow regeneration and co-flow regeneration processes. Available in sizes from 12 to 150 m3/hr, they feature mild steel pressure tanks and pipes.
