솔루션 접근법

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
산 및 염
pH 조절
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
산 및 염
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

Ferrous Sulfate
CAS 7720-78-7
산 및 염
pH 조절
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   끓는점:> 300 °C

Magnesium Hydroxide
CAS 1309-42-8
특수 첨가제
pH 조절
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

폴리머 및 수지
Peroxide-based oxidizer
2015 (HYDROGEN PEROXIDE, AQUEOUS SOLUTION, STABILIZED, WITH MORE THAN 60% HYDROGEN PEROXIDE) · Class
Oxidizes dissolved sulfide to sulfate or elemental sulfur for fast odor knockdown at problem points
융점:0 °C   끓는점:150 °C at 760 mmHg   밀도:1.11 at 20 °C

MEA-Triazine H2S Scavenger (Oilfield)
CAS 4719-04-4
특수 첨가제
보존
2810 (HEXAHYDRO-1,3,5-TRIS(HYDROXYETHYL)-5-TRIAZINE) · Class
Reacts irreversibly with H2S to form a water-soluble non-volatile dithiazine, scrubbing sulfide from gas and liquid streams
Solubility: Soluble (>=10 mg/ml at 24 °C)   Flash Point: > 93 °C
