TREATMENT CATEGORIES
Boiler & Cooling Chemical Programs
Six categories of specialty treatment — each with verified specifications from Lenntech's official datasheets.
SUEZ · OPTISPERSE HP
OptiSperse HP Series
- Type: Liquid phosphate + polymer dispersant
- Function: Metal oxide deposit & caustic corrosion control
- Application: Steam boilers fed with demin water & condensate
- Polymer: Synthetic carboxylated polymer for iron dispersion
- Compatible: FDA-regulated systems
- Dosing: Direct to boiler feed line or boiler
BWA · BELCLENE 810
Belclene 810 Biodegradable
- Type: Biodegradable antiscalant
- Application: Severe high-LSI cooling water systems
- Function: Threshold inhibition + crystal modification
- Targets: CaCO₃, CaSO₄, BaSO₄, SrSO₄
- pH range: < 2
- Appearance: Amber liquid
SUEZ / BWA
Oxygen Scavengers
- Function: Remove dissolved oxygen from boiler feedwater
- Chemistry: Hydrazine, carbohydrazide, DEHA, erythorbate
- Application: Steam boilers, closed loops
- Benefit: Prevents pitting corrosion in boiler tubes
- Dosing: Proportional to feedwater flow & O₂ level
- Monitoring: DULCOTEST oxygen sensors
BWA / SUEZ
Scale Inhibitors
- Type: Phosphonate, polycarboxylate, polymer blends
- Targets: CaCO₃, CaSO₄, Ca₃(PO₄)₂, silica, iron
- Application: Boiler feedwater, cooling towers
- NSF certified: For potable water systems
- Dosing: 2–10 mg/L (typical)
- Monitoring: DULCOMETER controllers
SUEZ / BWA
Corrosion Inhibitors
- Type: Filming amines, neutralizing amines, molybdates
- Function: Protect condensate return lines & boiler tubes
- Application: Steam boilers, closed cooling loops
- pH control: Neutralizing amines raise condensate pH
- Filming: Amine film protects metal surfaces
- Monitoring: Coupon racks, real-time corrosion monitors
BWA / SUEZ
Cooling Tower Chemicals
- Scale control: Belclene 810, OptiSperse HP
- Corrosion control: Molybdate, zinc, phosphonate blends
- Biocides: Bellacide 355, LiquiBrom 4600
- Dispersants: Polymer-based for suspended solids
- pH control: Sulfuric acid or caustic dosing
- Monitoring: DULCOMETER, coupon racks
