Hydrated Lime (Calcium Hydroxide) is an economical alkali for industrial wastewater treatment. In Kanpur, where cost-effective pH adjustment is critical for large-volume ETPs (tanneries in Jajmau, CETP, chemical plants), we supply Hydrated Lime (85-92% purity, economical grade for ETPs, fine powder form) to support tannery effluent neutralization (Jajmau — acidic wastes from pickling, bating, and some finishing processes), CETP operations (Jajmau CETP — pH adjustment, metals precipitation), chemical plant neutralization (Panki), and engineering industry wastewater. Kanpur's tannery cluster generates significant volumes of acidic and alkaline wastewater daily requiring cost-effective neutralization before biological treatment, ZLD, or discharge under UPPCB/CPCB Norms; hydrated lime is the most economical alkali for bulk pH adjustment and chromium precipitation requires economical hydrated lime.
As a cost-effective alkali for high-volume wastewater neutralization for Kanpur's leather (Jajmau), chemical, and engineering industry ETPs, it serves multiple applications: acidic wastewater neutralization (tannery pickling, bating, and some chemical wastes), heavy metals precipitation (chromium — from chrome tanning, lead, zinc), sludge conditioning (lime stabilization of biological and chrome sludge), and pre-treatment for ZLD systems (pH adjustment before RO and evaporators), meeting all quality standards including UPPCB/CPCB effluent discharge norms, CPCB guidelines for industrial ETPs under Namami Gange, and BIS specifications for industrial lime.
We offer multiple grades and customized specifications of Calcium Hydroxide to meet diverse industry requirements. Each batch is tested to ensure consistent composition, low impurities, and high performance standards, making it ideal for critical industrial uses.
