"Cleaner Water, Clearer Extracts – Grade by Grade for Assam."
Innovacorp India manufactures and supplies powdered and granular activated carbon for industrial buyers in Assam, where water quality and process clarity decide the final product. Assam's surface and groundwater sources carry natural colour, seasonal turbidity and, in several districts, dissolved iron — conditions that make adsorption a routine part of water and beverage processing. Our carbon grades are selected for those conditions, not for a generic catalogue.
Municipal and industrial water treatment in Assam usually works in stages: pre-treatment and filtration, followed by adsorption for taste, odour and colour, and finally disinfection. Activated carbon sits in that middle stage, either as a granular fixed bed or as a powdered slurry dose. In Guwahati and other urban centres, plants often keep GAC as the base bed and use PAC during peak-load periods when raw water colour rises after heavy rain.
Assam is India's largest tea-producing state, and its processing units handle large volumes of extract, beverage and food streams. Colour and haze in these streams come from polyphenols, oxidation products and fine suspended solids. A correctly sized powdered activated carbon dose adsorbs those colour bodies without stripping the characteristic profile of the product. The right dosage is found on a plant trial, because extract concentration and target colour vary from unit to unit.
The base material changes the pore size distribution. Coconut shell carbon tends to have a microporous structure that suits low-molecular-weight organics and taste-and-odour compounds. Coal-based carbon often gives a broader pore range for colour bodies and larger molecules. Wood-based carbon is usually chosen where a specific decolorization profile or cost balance is needed. There is no single "best" grade — the choice follows the target impurity, contact time and regeneration plan of your plant.
In Assam's humid conditions, an opened carbon bag can pick up moisture quickly. Moist carbon weighs more, blocks faster and shows a lower effective adsorption capacity than the datasheet suggests. Store bags sealed on pallets, away from floor dampness and direct rain, and use opened bags within a reasonable period. This single handling habit often explains why two plants using the same grade report different performance.
Typical parameters buyers ask about include iodine value, moisture content, bulk density, pH and mesh size. Exact values differ by grade and base material, and are confirmed on the product TDS. Final specification is confirmed after a lab trial on your own water or process stream.
For water treatment, PAC is typically dosed in the ppm range as a slurry, while GAC columns are sized by contact time and flow rate. For tea and food streams, dosage is set by the target colour value and is best fixed on a plant trial. Dosage values are not fixed in advance because raw water and extract quality change seasonally in Assam.
Standard industrial packing is used, with pack sizes on request. Store in a dry, ventilated area on pallets, away from direct rain, floor moisture and strong odours. Keep bags sealed until use and reseal opened bags.
Our team helps buyers in Assam match grade, mesh size and dosage to the specific water source or process stream. Selection support is provided by phone and shared data; final specification is confirmed after a lab trial.
Which grade suits iron and colour removal in Assam groundwater? A coal-based or coconut shell based GAC in a fixed-bed column usually works after pre-oxidation and filtration. The final grade is confirmed on a lab trial.
Can activated carbon decolorize tea extract? Yes. PAC is commonly dosed into tea extract and beverage streams; dosage is set on a plant trial.
PAC or GAC for a Guwahati water plant? GAC as the main bed, PAC for peak-load dosing, is a common arrangement.
How should carbon be stored in Assam's humidity? Sealed, on pallets, in a dry ventilated area; reseal opened bags and use them within a reasonable period.
