Overview

GNS supplies a comprehensive range of specialty water treatment chemicals to optimise the performance, efficiency and lifespan of water treatment systems — suitable for RO, UF, MBR, ETP, STP, cooling water and thermal desalination systems.

Product Range

Membrane Antiscalants Prevent precipitation of calcium carbonate, calcium sulphate, barium sulphate and silica on RO and NF membranes. Reduces CIP frequency, extends membrane life and improves system recovery.

Microbiocides Oxidising and non-oxidising biocides to control biological fouling in membrane systems, cooling towers and storage tanks — effective against bacteria, algae and fungi.

Membrane Cleaning Chemicals

• Alkaline cleaners — remove biofilm and organic fouling
• Acidic cleaners — dissolve mineral scale and metal oxides
• Multi-stage cleaning sequences for combined fouling

Antiscalants for Multi-Effect Flash Distillation (MED / MSF) Specially formulated for thermal desalination — prevent carbonate and sulphate scale on heat exchanger surfaces at elevated temperatures.

Coagulants & Flocculants

• Poly electrolytes (various molecular weights) for ETP and STP
• Anionic, cationic and non-ionic flocculants for sludge dewatering

Biological Treatment Chemicals

• Bio cultures and nutrients for STP and ETP bacterial seeding
• Enzyme-based formulations for sludge volume reduction
