ソリューションアプローチ
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 (6)
Calcium Nitrate
CAS 13477-34-4
酸・塩類
pH調整
In catalog. Supplies nitrate as a preferred electron acceptor so bacteria respire on nitrate instead of generating sulfide; prevents H2S formation rather than treating it afterward
Physical Description: Colorless hygroscopic crystals

Ferric Chloride
CAS 7705-08-0
酸・塩類
High-performance coagulant
1773 (FERRIC CHLORIDE) · Class In catalog. Ferric iron precipitates dissolved sulfide as insoluble iron sulfide, removing it from the liquid and vapor phase
融点:306 °C 沸点:315 °C at 760 mmHg (Decomposes) 密度:2.8 at 20 °C (anhydrous solid)

Ferrous Sulfate
CAS 7720-78-7
酸・塩類
pH調整
In catalog. Iron(II) reacts with sulfide to form FeS precipitate; a lower-cost iron source for sulfide binding
Physical Description: Ferrous sulfate appears as a greenish or yellow… Appearance: White orthorhombic crystals, hygroscopic 沸点:> 300 °C

Magnesium Hydroxide
CAS 1309-42-8
特殊添加剤
pH調整
In catalog. Raises and buffers pH, shifting the sulfide equilibrium toward non-volatile bisulfide ion and suppressing H2S off-gassing without overshoot
Physical Description: White odorless solid; Colorless or white solid;… Appearance: White, hexagonal crystals Odor: Odorless
