Wastewater — Process Challenge

pH-Einstellung zur Einhaltung von Abwasserverordnungen

Der pH-Wert des Abwassers muss in den zulässigen Einleitbereich (typischerweise ~6–9) neutralisiert werden, unabhängig davon, ob der Strom sauer oder alkalisch ankommt. Das Konzept hält starke Mineralsäuren und Laugen für beidseitige pH-Korrektur vor

Lösungsansatz

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.
