Groundwater Contaminant Removal — Process Challenge

불소·비소 제거

불소 또는 비소 최대오염물질농도를 초과하는 지하수 시스템은 처리수를 규제 기준 내로 맞추기 위해 흡착 매체와 응집제를 대량으로 조달합니다. 수요는 정수기 구매자에 한정되지 않고 시정 및 산업용 대용량 구매자까지 확대되며, 활성알루미나가 대표적인 흡착제입니다

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.
