Tender Overview

The procurement is led by the Power Department in NORTH WEST DELHI, DELHI 110034, for ALGAECIDES AND BIOCIDE and HYDROXYETHYLENEDIPHOSPHONIC ACID (HEDP) solutions intended for cooling water treatment. The total quantity is 4100 kilograms, packaged as 82 pieces of 50 kg each, with 2 feasible delivery lots and a 30-day delivery window from the schedule issued by the PPS-I and PPS-III Bawana chemistry departments. The contract spans one year from the GeM PO date. The bid specifies a non-oxidizing, ammonium-based, quarterly biocide formulation that detaches biofilms and reduces under-deposit corrosion, with emphasis on water miscibility and compatibility with oxidizing biocides. Emphasis on environmental compliance and a broad pH range (6–9) are noted, with a focus on ensuring complete dispersion in the cooling system. This tender requires exact dosing guidance and a robust quality framework, including MSDS and NABL-compliant test certificates.
