Water treatment solutions

The Ion Exchange Process:

Water Softeners remove hardness from water with the use of a process known as ion exchange. The media, called resin, in the softener is charged with sodium (or potassium) ions. When the hardness ions come in contact with the resin beads the hardness ions are collected and the sodium (or potassium) ions are released, thus the term ion exchange. The hardness ions are exchanged for sodium (or potassium) ions. The typical captions found in the raw water are exchanged within the resin bed for sodium or potassium, as shown in the illustration. In normal circumstances, when two-thirds of the resin bed is exhausted, the softener will allow hardness to slip through. When this occurs, it is time to regenerate or recharge the resin bed using a salt and water mixture, known as brine. Sodium chloride (NaCl) or potassium chloride (KCl) are normally used for this purpose. Regenerating the resin bed refreshes its ability to exchange ions.

Softener Resin :

Ion exchange resins are polymers that have the capacity to exchange ions with ions in a solution that is passed through them. The use of ion exchange resins servesa variety of applications like domestic, commercial, industrial water softening, and many more. We use resins which come in a variety of chemical compositions, polymer structures, and particle sizes to be in sync with the current and developing industry needs and requirements.

Fiberglass Reinforced Plastic (FRP) Vessel :

  • The strength and corrosion resistance of FRP vessels is unmatched by stainless steel or other poly vessel.
  • Quality assurance is proved by NSF certificate.
  • FRP Vessels are widely compatible with commercial and industrial control valves.
  • Manways, side flanges and optional water distribution systems are available for customized requests.
  • ABS Base - To prevent cracking.
  • Nylon Top threading - Leak proof at top roof condition and temperature.

Features and Benefits of FRP Versus Metal :

  • No rust or need for painting.
  • Fewer problems relative to heat, stress, conductivity, and climatic conditions.
  • Superior corrosion resistance in many applications versus rubber lined and bare metal.
  • Half the price of stainless steel, yet up to 5-10 times longer lasting in very corrosive environments.
  • Lightweight – 2/3 the weight of aluminum, ¼ the weight of steel – therefore, easier to handle
  • Recent resin improvements relative to heat, impact, and crack resistance are encouraging extensive use of FRP versus metal by major companies.
  • More skid (slip) resistant than metal.
  • Significant design freedom.
  • Non-conductive (prevents shorting out electrical equipment).
  • Can be efficiently heat traced from bottom of tank (ABS Base).
  • No flammability concerns/hassles with welding.

Birm Media :

It is an effective and inexpensive method of removing dissolved iron and manganese compounds from raw water supplies. It may be used in either gravity-fed or pressurized water treatment systems. Birm mediaacts as an insoluble catalyst to enhance the reaction between dissolved oxygen (D.O.) and the iron compounds.

Birm Media can be utilized at high operating temperatures and high differential pressures without breakdown of the media and is classified as a “high rate” media where the filters can be run at very high linear velocities with excellent results.

Unlike other medias, it does not require extensive pre-conditioning. Birm Media effectively removes iron, manganese and hydrogen sulfide from natural waters. Water for industrial and domestic uses must be substantially iron and manganese free.

Advantages :

  • Under proper conditions, no chemicals need to be purchased for maintenance.
  • Regeneration not required.
  • Iron removal efficiency is extremely high.
  • Negligible labor cost: only periodic backwashing required.
  • Durable material with a long life and wide temperature range.
  • Light in weight.

Physical properties :

  • Color: Black
  • Bulk Density: 40-45 lbs./ cu. ft.
  • Mesh Size: 10 x 40
  • Specific Gravity: 2.0 gm/cc
  • Effective Size: 0.48 mm
  • Uniformity Coefficient: 2.7

Sand Filter Media (Silex, Cores & Fine Sand) :

To removethe turbidity and suspended solids as low as 10-20 microns, a sand-Silex- Cores filter or dual media filter/multi-media filter. Dual media filters provide very efficient particle removal under the conditions of high filtration rate. Inside a sand-Silex filter is a layered bed of filter media.

The bed is graded from bottom to top as follows :

With such functioning where filter media is graded this way, the sand -Silex Filter is able to run for longer times before a backwash is necessary. A sand -Silex filter or multi-media filter consists of 2 main parts:

  • A composite pressure vessel with Multiport Valve.
  • Graded beds of sand and Silex.

Sand is used to remove the suspended particles and Silex is used to remove the odor, color, etc. to make the water fit for different applications. Periodically, the sand-anthracite filter will backwash, which changes the water flow through the sand-Silex filter.

Iron Removal Media Filter :

Iron removal filter is a processed catalytic filtration unit where the raw water passes through the layer of compressed air, processed catalyst & quartz filter media respectively. The dissolved ferrous iron salts are converted into insoluble ferric salt and precipitated over the filter bed and then the iron free filtered water comes out. Only backwashing with clear water and compressed air is required for cleaning the bed.

Features :

  • Easily installed
  • Non-clogging and non-choking
  • Economical
  • Total elimination of iron and turbidity from drinking water without altering
  • Instant supply of pure water
  • Online installation with main water supply, hence pure water is available fromall outlets in the house
  • Non-electrical device ensures uninterrupted supply without recurringexpenses
  • Multiple valve operation
  • Saves up to 25% of expensive detergents
  • Prevents discoloration of clothes
  • Stops hair from getting sticky and hair loss
  • Protects geysers, coolers, washing machines.

Multiport Valve :

Constructed from heavy duty ABS and GFPP, Multiport valves are designed for high performance and working pressures.

  • Durable lever action handle
  • 6-way multiple valve positions
  • Top and Side mount configurations
  • Nylon – Bottom Threading
  • Rated at 400 kPa

Multiport Valves Main function :

Filter - Downward flow through the filter bed to outlet.

Backwash - Upward Flow through the filter bed to waste.

Rinse - Downward flow through the filter bed to outlet.

Cleaning a filter simply requires shifting the Multiport lever from the ‘filter’ position to the ‘backwash’ position, which reserves the flow of water in the filter, flushing the filter bed.

Air Release Valve :

  • Air release Valve are hydro mechanical devices designed to automatically release or admit air during the filling, draining, oroperation ofawater pipeline or system.
  • The safeoperation and efficiencyofapipeline are dependent on the continual removal of airfrom the pipeline.
  • Air in pipelines:Water containsat least two percent dissolved air by volume in standard conditions, but can contain more, depending on the waterpressure and temperature within the pipeline.Therefore, when water is pressurized,its capacity to hold airisgreatly magnified.
  • It is much useful to prevent air - pockets in pipeline.
