Manufacturers, Exporters and Suppliers of Color Removal Chemicals for Wastewater Treatment – Effective Decolorizing Agents in Assam

Innova Corporate (India) offers a Color Removal Chemical – a proprietary blend of dicyandiamide-formaldehyde polymer (DCDA-F) and polyamine derivatives specifically engineered for Assam's textile (silk) and tea industry effluents. The silk industry in Assam – Sualkuchi (the "Manchester of Assam") – uses natural and synthetic dyes (indigo, etc.), producing wastewater with intense color. Tea factory effluent contains tannins and theaflavins that give a dark brown color. This color removal chemical works by forming insoluble complexes with dye and tannin molecules through ionic and hydrogen bonding. It is effective at low dosages (30-100 ppm) over pH 5-11. Unlike conventional coagulants (alum, ferric), this product produces compact, non-leachable sludge (20-30% less volume). For Assam's silk dyeing CETP (Sualkuchi), adding this chemical after biological treatment reduces color to <100 ADMI meeting APCB standards for discharge into Brahmaputra. For tea factory ETPs, it removes tannin color effectively. The product is compatible with polyelectrolyte flocculants (anionic or non-ionic) for enhanced settling. For zero liquid discharge (ZLD) systems for silk and tea clusters, this chemical is essential before RO membranes to prevent dye/tannin fouling. Available as a 30-40% active liquid (amber to brown). Dosing using a positive displacement pump. We provide color measurement kits (handheld spectrophotometer or ADMI comparator) for on-site monitoring. Pack sizes: 200L drums, 1000L IBCs. For large users (CETPs), bulk tanker supply is available. Shelf life: 12 months (store below 40°C/104°F). We provide color removal efficiency testing using UV-Vis scans and ADMI calculations for Assam's silk and tea industries.
