MULTI MEDIA FILTER

(ZEOLITE/SAND/GRAVIL/RESIN)

FOR SALTS/TDS/SCALE REMOVAL

- According to our conversation and your request todesign,supply and installation a multi media filter (zeolite/sand/gravil/resin) for scale,salinity and dissolved solids treatment from circulation water of chiller system of your factory with out put capacity(5m3/hrs)

- We are honored to provide our quotation to you:-

Technical introduction

Principle Factors Responsible for Scale Formation & hardness

 Calcium content of water

 Alkalinity or pH of water

 Temperature of re-circulation water

 Higher concentration of solids (TDS)

 Insufficient bleed off from cooling towers

THE general combinations of resins to achieve reduction in dissolved solids & salinity

There are various possible combinations and arrangements of ion-exchange resins.

Each resin or combination is effective for controlling a particular parameter more effectively.

It is recommended to consult a water treatment equipment supplier for appropriate selection.

The few resins are:

Resin Function:-

Sand/gravil softener to remove hardness I,e (ca,mg)

Zeolite Softener To remove hardness i.e. Ca, Mg and heavy metals (fe,pb,as,ca,hg,mn)

Weak Acid Cation (WAC) To remove the weak acid cations, i.e. hardness, Ca++ or Mg++ associated with alkalinity OH-, CO3--, and HCO3--

Strong Acid Cation (SAC) To remove all the cations & anions including Ca++, Mg++, Na+, K+

Weak Basic Cation (WBC) To remove salts of strong acids, SO4--, C l-, NO3-

Strong Base Anion (SBA) To remove all anions including SiO2 and CO2

Mixed Bed (MB) It is a mixture of SAC and SBA resins. The function is to polish and remove residual remaining ions in water.

What are sand/gravil ?

Sand filters provide clean water by reversing flow through the sand bed and backwashing dirt out the top of the filter.

With this setup, dirty water enters the top of the filter through the over-drain assembly and is distributed over the sand media bed.

The sand bed traps the particles and allows the filtered water to pass through the under-drain assembly and back to the cooling tower sump.

As dirt accumulates, it causes a pressure differential across the filter.

When the differential pressure reaches set point, flow through the sand bed is reversed, backwashing accumulated dirt out of the top of the filter and down the drain.

What are Zeolites?

Zeolites are complex silicates consisting of macromolecules of several metallic and non-metallic oxides.

These are simply represented as Na2Ze.

They hold sodium ion in loose fashion and consequently when they are treated with a solution containing positive ions such as Ca & Mg, these shall be exchanged with sodium ions contained in Zeolite.

Zeolite used for water softening purposes can be natural or synthetic.

Synthetic inorganic zeolite, are more effective than natural zeolite, but are less durable.

These are not capable of resisting acids, and therefore cannot be used in the exchange of hydrogen

SOFTENING BY ION EXCHANGE

The process involving removal of hardness producing salts from water is softening of water.

The softening of water by ion exchange is relatively simple and effective.

The process consists of passing hard water through a column of cation-exchange resin in the sodium form.

The sodium on the resin replaces the objectionable calcium and magnesium ions.

Why Ion Exchange Resins are Important?

Resin is a heart of ion-exchange system.

The resins perform a function of exchanging the undesirable ions in the water to the desirable one

What factors impact the design of Ion Exchange system?

A reasonably accurate water analysis is required to design an ion exchange installation for water treatment.

Following ions are most commonly found in a water sample.

 Alkaline Earth Cations: Ca++ or Mg++

 Alkaline Metal Cations: Na+, K+

 Total Alkalinity (ALK): OH-, CO3--, and HCO3--

 Total Salts of Strong Acids (TMA): SO4--, C l-, NO3-
