Water Treatment Chemicals

Granular activated carbon has a relatively larger particle size compared to powdered activated carbon and consequently, presents a smaller external surface. Diffusion of the adsorbate is thus an important factor. These carbons are therefore preferred for all adsorption of gases and vapors as their rate of diffusion are faster. Granulated carbons are used for water treatment, deodorization and separation of components of flow system. The most popular aqueous phase carbons are the 12×40 and 8×30 sizes because they have a good balance of size, surface area, and loss characteristics. In gas phase adsorption, granular carbon is almost always used because the pressure drop in the carbon bed is of prime importance and only granular carbon will allow sufficient flow with an acceptable pressure drop. 
Specification :

The palletized carbon is a cylindrical-shaped carbon made from a carefully selected grade of coal. It is palletized under rigidly controlled conditions using a high quality binder. This activated carbon possesses high mechanical strength and lends itself well to numerous cycles of regeneration. Its shape offers a low flow resistance.

·  Activated carbons (powdered) are derived from either hard wood charcoal or pine wood charcoal. Naturally therefore these carbons are vegetable origin. In the activation process the super heated steam reacts with wood charcoal (water gas reaction) and opens up fresh spaces in an already porous charcoal.  new pores are created allowing access to the molecules to be absorbed on the surface of the charcoal. 
The powdered activated carbons are used in the following industries:

·         Purification of higher fatty acid

·         Food industries (glucose, fructose etc.)

·         Soft drink and effluent treatment 

·         Dye and dye intermediates

·         Purification of acidic and basic electroplating bath

·         Purification of edible and inedible oils.

This type of carbon is made from coconut shell and activated through high temperature & high pressure steam. This carbon is impregnated with silver, a known bacteriostatic agent to inhibit the growth of bacteria with in the carbon media. This product is used only for manufacturing or fabricating bacterio-static water filter products for home use, cartridges, potable water, and beverage water. This product is totally compatible with all municipal water treatment use. 

Chlorination of water is one of the worldwide-accepted method of disinfection and purification of water to make it potable. For inexpensive, economical and timely purification of drinking water, under the various schemes of protected water supply in rural areas, Chlorine Tablets are highly effective. This is the easiest method of disinfection and purification of water.

Uses of Chlorine Tablets:

Chlorine provides a strong residual in the distribution system.

Chlorine is easy to apply.

Chlorine is a relatively inexpensive disinfecting agent.

Chlorine is effective at low concentrations.

Applications:

It is used for disinfecting of Drinking water, Industrial residue and Pool cleaning.

Due to its decolorizing property it is used in whitening of vegetable fibers like cotton, linen etc. and of paper pulp.

Ion exchange resins are polymers that are capable of exchanging particular ions within the polymer with ions in a solution that is passed through them. In water purification the aim is usually either to soften the water or to remove the mineral content altogether. Ion exchange resins are classified as cation exchangers, which have positively charged mobile ions available for exchange, and anion exchangers, whose exchangeable ions are negatively charged. Both anion and cation resins are produced from the same basic organic polymers. They differ in the ionizable group attached to the hydrocarbon network. It is this functional group that determines the chemical behavior of the resin. Resins can be broadly classified as strong or weak acid cation exchangers or strong or weak base anion exchangers. In an ion exchange process, cations or anions in a liquid solution (usually aqueous) replace dissimilar and displaceable ions of the same charge contained in the ion exchange resin.

Activated Alumina

We are providing Activated Alumina, which is a widely used filtration media. It is used to treat ores and works by making them highly porous and absorptive. These are effective in removing the excess quantities of fluoride, arsenic & selenium and variety of other contaminants for the water. In order to maintain the purity levels and allow the filtered water to remain effective, appropriate regenerate such as alum or acid needs to be added or periodic cleaning has to be performed.

 Advantages of PURONCHLOR Na tablets:

·         Stable for more than 2 years

·         Accurate: always yielding the stated level of available chlorine.

·         Convenient and easy to use. Just add to water and allow to dissolve. The speed of solution can be enhanced by the use of warm water and/or by stirring.

·         Economical in use: the tablets provide an easy to use dilution system that eradicates the over-dosing that is common with liquid bleach and more importantly minimizes any under-dosing potential.

·         Easy to store and distribute - no spillages, no leaks.

·         Much safer to use than liquid bleach - reduced risk of accident and personal injury.

·         Less corrosive than liquid bleach. Tests have shown that nearly all metals in common use are more readily corroded by liquid bleach than by PURONCHLOR Na tablets.

·         Possess greater biocidal properties, strength for strength, than liquid bleach, especially in the presence of soiling.

·         Dissolves in solution to a near neutral pH solution - safer for operatives, unlike sodium hypochlorite which is invariably pH 9.0 -12.0
