Typical Treatment Workflow
1
System Assessment
Characterize operating conditions—fluid composition, temperature, pressure, flow rates—and benchmark current treatment performance.
2
Chemistry Selection
Match base chemicals to your operating envelope. Factor in compatibility with existing programs, regulatory constraints, and downstream impacts.
3
Dosage & Delivery
Determine optimal treat rates through jar testing or field trials. Configure packaging (drums, totes, ISO tanks) to match consumption and storage logistics.
4
Monitoring & Adjustment
Track KPIs—coupon rates, residuals, separator performance, water quality. Adjust chemistry and dosage as conditions change.
Recommended Chemistries (2)
Dimethicone
CAS 9006-65-9
Silicone Fluids & Oils
Fastest foam knockdown at 50-200 ppm for machine dish and CIP
Polydimethylsiloxane is the active in silicone antifoams; spread (in practice compounded with hydrophobic silica) it enters foam lamellae and ruptures them for rapid knockdown at low ppm in machine-dish/CIP liquors

PPG 14 Butyl Ether
CAS 9043-30-5
Glycols & Polyols
Moisture Control
Polypropylene-glycol butyl ether, a non-silicone polyglycol defoamer for silicone-free specs and surfaces where PDMS carryover onto ware is a concern
Melting Point: 33-36 °C   Boiling Point: 615.857 °C at 760 mmHg   Solubility: miscible
