pH Booster
Raises and holds boiler water alkalinity in the correct range so steel surfaces stay passive and acidic corrosion is prevented.
Chemicals
Boiler, cooling tower, ETP / STP waste water and RO treatment chemicals: what each one does, shown with the plant it protects.
What each chemical does
Water treatment chemicals and their functions
Every chemical programme is selected for the plant it protects. See what each of our boiler, cooling tower, ETP / STP and RO chemicals does.
Boiler Chemicals
Protect boiler tubes, drums and condensate lines from scale, corrosion and carry-over while improving fuel efficiency.
Sludge Conditioner
Keeps hardness salts and iron as soft, non-sticky sludge that stays suspended and leaves with blowdown instead of baking onto tubes.
Anti-scalants
Sequester calcium, magnesium and silica to stop hard scale forming on heating surfaces, keeping heat transfer high and fuel use low.
Oxygen Scavengers
Remove dissolved oxygen from feed water to prevent pitting corrosion in the boiler, economiser and feed lines.
Fireside Chemicals
Condition soot, slag and clinker on the fire side, improving combustion and keeping flue passages and tubes clean.
Antifoams
Break foam in boiler water to prevent priming and carry-over of water and dissolved solids into the steam.
Corrosion Inhibitors
Form a protective film on boiler and condensate-line metal to prevent corrosion caused by oxygen and carbon dioxide.
Descaling Chemicals
Dissolve existing scale and rust deposits during shutdown cleaning, restoring heat transfer and extending tube life.
Metal Passivator / Neutralizers after Descaling
Neutralise residual acid after descaling and rebuild a passive oxide layer so freshly cleaned metal does not flash-rust.
Cooling Tower Chemicals
Keep heat exchangers, condensers and fills clean and corrosion-free so the cooling circuit delivers design approach temperature.
Corrosion Inhibitors (phosphate, zinc & alloy based)
Phosphate, zinc and alloy-based programmes form a protective film on mild steel, copper and alloy surfaces of exchangers and pipelines.
Scale Inhibitor
Keeps calcium carbonate, sulphate and silica in solution at higher cycles of concentration, preventing scale and saving make-up water.
Biocides (oxidizing & non-oxidizing)
Kill bacteria, fungi and Legionella in recirculating water; alternating both types prevents microbial resistance.
Algaecides
Control algae on basins, decks, distribution channels and fills exposed to sunlight, preventing blockage and fouling.
Bio Dispersants (foaming & non-foaming)
Loosen and lift biofilm and slime so biocides penetrate better and debris is flushed out with blowdown.
Oil Dispersants
Emulsify oil and grease leaking in from the process so they do not coat heat-exchanger surfaces or foul fill media.
Bio Detergents
Clean organic and biological fouling from system surfaces during online or offline cleaning to restore heat-transfer efficiency.
ETP / STP Waste Water Chemicals
Help effluent and sewage treatment plants meet discharge norms for COD, BOD, TSS, colour and odour, and handle sludge efficiently.
Poly Electrolytes
Cationic and anionic polymers bridge fine particles into large, fast-settling flocs in clarifiers, improving TSS and COD removal.
Sludge Dewatering
Conditions sludge before the filter press, belt press or centrifuge so water separates easily and a drier cake is produced.
Water Decoloring
Removes dye and colour from textile, paper, pharma and distillery effluent by coagulating colour molecules for separation.
Defoamers
Knock down foam in aeration, equalisation and outlet tanks, preventing overflow and improving oxygen transfer.
Lime / Alum
Lime neutralises acidic effluent and precipitates heavy metals; alum coagulates suspended solids and phosphate in primary treatment.
Bio Cultures
Specialised bacteria and nutrients seed and boost biological treatment, speeding start-up, improving BOD/COD reduction and controlling odour.
RO Water Treatment Chemicals
Protect RO and UF membranes from scaling, fouling and chlorine damage so the plant keeps its output, recovery and salt rejection.
RO Antiscalants (high & low silica, high & low pH)
High/low silica and high/low pH grades prevent carbonate, sulphate, silica and metal scale on membranes, allowing higher recovery.
Low pH Cleaners
Acidic cleaners dissolve inorganic scale and metal oxides such as calcium carbonate and iron from the membrane surface.
High pH Cleaners
Alkaline cleaners remove organic fouling, biofilm and colloidal silt that reduce permeate flow.
C.I.P Chemicals
Complete clean-in-place programmes restore flux and salt rejection without dismantling membranes from the pressure vessels.
Chlorine Inhibitors
Neutralise residual chlorine in RO feed water to protect polyamide membranes from irreversible oxidation damage.
Chlorinating Agents
Disinfect raw water and pre-treatment to control bacterial growth before filtration and membranes.
Ultra Filtration Cleaning Chemicals
Clean UF membranes of organics, biofouling and particulates to recover permeability and backwash efficiency.
Hydrochloric Acid (HCl)
Lowers feed pH to limit carbonate scaling and is used for acid cleaning and cation resin regeneration.
Caustic (NaOH)
Raises pH for alkaline membrane cleaning and silica control, and regenerates anion exchange resin.
Hypochlorite
Oxidising disinfectant for raw water, storage tanks and pre-treatment sanitisation.
Sodium Meta Bi-Sulphite
Dechlorinates RO feed water and preserves membranes during storage or plant shutdown.
