Chemical Treatment & Oxidation

Chemical Coagulation, Flocculation, pH Control, Antiscalant, and Advanced Oxidation for Industrial Water Treatment

Chemical treatment encompasses the application of reagents and oxidants to alter water chemistry, remove contaminants, control scaling, or prepare water for downstream membrane and separation processes. GWTS designs and delivers chemical treatment programs as stand-alone systems or as integrated components of larger membrane and separation treatment trains, including produced water, tailings water, and high-TDS industrial wastewater applications.

Chemical Treatment Services

  • Coagulation & Flocculation: Polymer and inorganic coagulant dosing for suspended solids and colloid removal — DAF and clarifier optimization
  • pH Adjustment: Acid and caustic dosing systems for RO pretreatment, scaling control, and process chemistry management
  • Antiscalant Programs: Scale inhibitor selection and dose optimization via laboratory scaling index analysis (LSI, RSI, S&DSI)
  • Advanced Oxidation (AOP): H₂O₂/UV, ozone, and Fenton-based oxidation for naphthenic acid destruction, organic removal, and disinfection
  • Biocide Programs: Oxidizing and non-oxidizing biocide selection for microbiological control in membrane and process water systems
  • Chlorination / Dechlorination: Dosing system design for disinfection and membrane protection
