Solution Approach
RawSource supplies the base chemicals that go into these programs. We can help with product selection, grade matching, and sourcing from multiple origins for supply security.
Typical Treatment Workflow
1
Water & System Assessment
Characterize the water and the system — hardness, alkalinity, pH, TDS/conductivity, microbial load, and the metallurgy and temperatures of the equipment being protected.
2
Program & Chemistry Selection
Match coagulants, flocculants, scale and corrosion inhibitors, biocides, or pH adjusters to the water profile and discharge limits, factoring compatibility with any existing program.
3
Jar Testing & Dosing
Confirm coagulant and flocculant dose and feed point by jar test, set inhibitor and biocide treat rates, and size packaging (drums, totes, bulk) to consumption.
4
Monitoring & Control
Track residuals, turbidity, ORP, corrosion coupons, and effluent compliance, adjusting chemistry and dose as feedwater and load change.
Recommended Chemistries (4)
Caustic Soda (Sodium Hydroxide) Beads
CAS 1310-73-2
Acids & Salts
Primary alkali for pH raise
1824 (SODIUM HYDROXIDE SOLUTION) · Class Sodium hydroxide sets and holds boiler-water alkalinity/pH in the protective range and supplies the OH- needed to form hydroxyapatite with phosphate
Melting Point: 318 °C Boiling Point: > 130 °C at 760 mmHg Density: 1.5 at 20 °C

Monosodium Phosphate
CAS 7558-80-7
Specialty Additives
pH Adjustment
Supplies orthophosphate that reacts with residual Ca2+ under boiler alkalinity to form soft calcium hydroxyapatite sludge instead of hard tube scale
Melting Point: Decomposes at 75 Density: 2360 kg/cu m Solubility: 121 g/L

Sodium Tripolyphosphate (STPP)
CAS 7758-29-4
Acids & Salts
Chelation / Sequestration
Polyphosphate both sequesters hardness and reverts to orthophosphate at temperature, reinforcing the phosphate residual that precipitates calcium as removable sludge
Melting Point: 622 °C Density: 2.52 g/cm3 Solubility: Freely soluble in water. Insoluble in ethanol

Polyacrylic Acid Sodium (PAAS)
CAS 9003-04-7
Polymers & Resins
Conditioning
Conditions the phosphate/calcium sludge into a fine, fluid suspension so it discharges cleanly with blowdown rather than caking on tubes
