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 (5)
Sodium Molybdate
CAS 7631-95-0
Specialty Additives
Molybdate corrosion inhibitor
Anodic passivator for mild steel; molybdate reinforces the protective gamma-Fe2O3 oxide film and is far less toxic than chromate, working synergistically with zinc
Physical Description: White solid; Colorless crystalline solid Melting Point: 687 °C Solubility: Solubility in water, g/100ml at 100 °C: 84

Zinc Nitrate
CAS 7779-88-6
Specialty Additives
Conditioning
1514 (ZINC NITRATE) · Class Cathodic inhibitor; Zn2+ precipitates as Zn(OH)2 at cathodic sites, throttling the oxygen-reduction reaction that drives steel corrosion
Physical Description: Zinc nitrate is a colorless crystalline solid. … Appearance: White powder Melting Point: 36 °C

Tolyltriazole (TTA / Methylbenzotriazole)
CAS 29385-43-1
Specialty Additives
Yellow metal protection
Tolyltriazole chemisorbs a Cu-TTA film on copper/brass, stopping dissolution and dezincification; more chlorine-tolerant than benzotriazole

Benzotriazole (BTA)
CAS 95-14-7
Specialty Additives
Copper corrosion inhibitor
Benzotriazole forms a tenacious Cu-BTA chelate film that passivates yellow metals and suppresses galvanic copper plating onto steel. (Spine tags Biocidal; the role here is copper corrosion inhibition.)
Melting Point: 98–100 °C Boiling Point: 204 °C at 15 mmHg Density: 1.36 g/cu cm at 20 °C

2-Mercaptobenzothiazole (MBT)
CAS 149-30-4
Specialty Additives
Corrosion Inhibition
2811 (2-MERCAPTOBENZOTHIAZOLE) · Class Thiol-bearing azole gives fast initial copper passivation and is often paired with TTA for rapid film establishment on fresh metal
Melting Point: 177–181 °C Boiling Point: Decomposes Density: 1.42 at 20 °C
