Reduce overflow & carryover
Restore tank freeboard and reduce foam-driven solids carryover into downstream units.
Product Water Treatment
Antifoam for Water Treatment
Process-matched defoamer used to control foam in wastewater treatment, clarification, aeration, digesters, and sludge handling. Options by chemistry, activity, and compatibility.
Packaging: drums / IBC / bulk (as applicable)
Documentation: SDS / TDS / COA on request
Selection by chemistry, activity & downstream constraints
Commercial highlights
Foam control that fits your plant reality—fast selection, repeatable supply.
- Options by chemistry: silicone / polyether / oil-based / emulsion
- Knockdown + persistence choices matched to foam source and shear conditions
- Compatibility-aligned grades for polymer programs and downstream separation
- Repeatable sourcing lanes + documentation pack (SDS/TDS/COA) on request
Common buying goals
What operators typically optimize when selecting an antifoam.
Stabilize operations
Improve aeration efficiency and reduce nuisance shutdowns caused by persistent foam events.
Protect downstream separation
Select chemistry that respects clarification, filtration, and dewatering requirements.
Applications
Typical usage patterns. Tell us your process, foam behavior, and constraints and we’ll align the right chemistry and activity. Antifoam selection is most effective when it is matched to the foam source and the unit operation.
Aeration basins & biological treatment
Surface foam reduction to stabilize operation and reduce carryover (chemistry matched to stream and polymer program).
Equalization & clarification
Foam knockdown in tanks and clarifiers where turbulence, surfactants, or organics drive foam formation.
Digesters, sludge thickening & dewatering
Foam control in high-solids streams and mechanical dewatering where persistent foam can reduce throughput.
Performance targets (what plants usually measure)
Define the win condition and matching gets much faster.
Knockdown speed
How quickly the foam collapses after dosing at the selected point.
Persistence under aeration
How long control lasts under continuous air and agitation (grade-dependent).
Side effects & compatibility
Impact on clarification, floc formation, filtration, odor, and downstream reuse/discharge constraints.
Common foam drivers (selection clues)
These cues help narrow chemistry and activity quickly.
- Surfactants from detergents/CIP or industrial discharges
- High organics, fats/oils/grease (FOG), or fermentation byproducts
- Polymer carryover or changes in coagulant/flocculant program
- High solids and shear in sludge thickening/dewatering equipment
Technical overview
A procurement-focused view of antifoam chemistries and how they typically map to wastewater unit operations.
Silicone-based
Often selected for strong knockdown and persistence. Used when downstream constraints allow silicone chemistry.
Polyether / EO-PO based
Common choice for “silicone-free” requirements and where compatibility with certain streams is prioritized.
Oil-based / emulsion systems
Used for specific foam sources and process conditions; emulsion stability and storage profile are part of selection.
How grade selection is typically decided
These are the “make-or-break” variables for quote accuracy.
Stream chemistry
Surfactants, oil/grease, solids load, salts, and treatment chemicals can change foam behavior and antifoam performance.
Unit operation conditions
Shear, aeration intensity, and temperature affect persistence and the required activity level.
Downstream constraints
Clarification/filtration, reuse goals, discharge requirements, and silicone-free policies guide chemistry choice.
Dosing & handling (practical notes)
Final guidance is grade-specific—these are common planning points.
- Dosing point is typically selected near the foam generation source for best efficiency
- Some grades can be pre-diluted for improved distribution (confirm on TDS)
- Storage conditions (freeze/heat) matter for emulsions and water-based carriers
- Confirm materials compatibility for pumps, seals, and transfer lines
Typical specifications & formats
Values depend on chemistry and customer requirements. Confirm details on quotation (TDS/COA).
