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)
Calcium Hydroxide (Pickling Lime)
CAS 1305-62-0
Specialty Additives
pH Adjustment
Hydrated lime raises pH to the minimum-solubility window where dissolved metals drop out as M(OH)n; also adds Ca that aids floc density and sulfate removal
Melting Point: 580 °C (Decomposes) (Loses H2O) Boiling Point: Decomposes Density: 2.24 at 20 °C

Calcium oxide (quicklime)
CAS 1305-78-8
Specialty Additives
pH Adjustment
1910 (CALCIUM OXIDE) · Class Quicklime slakes to Ca(OH)2 for the same hydroxide precipitation, a lower-cost high-alkalinity source for large flows
Melting Point: 2572 °C Boiling Point: 2850 °C at 760 mmHg Density: 3.3 at 20 °C

Magnesium Hydroxide
CAS 1309-42-8
Specialty Additives
pH Adjustment
Self-buffering alkali (~pH 9) that precipitates metals while resisting overshoot, producing a denser, lower-volume sludge than caustic
Physical Description: White odorless solid; Colorless or white solid;… Appearance: White, hexagonal crystals Odor: Odorless

Caustic Soda (Sodium Hydroxide) Beads
CAS 1310-73-2
Acids & Salts
Primary alkali for pH raise
1824 (SODIUM HYDROXIDE SOLUTION) · Class Sodium hydroxide gives precise, fast pH elevation to hit each metal's minimum-solubility pH where lime handling/sludge is undesirable
Melting Point: 318 °C Boiling Point: > 130 °C at 760 mmHg Density: 1.5 at 20 °C
