Adsorption Filtration — Process Challenge

수처리용 활성탄: GAC 및 PAC 대량 공급

상수도 및 산업용수 처리 시설은 RO 막 또는 최종 방류 전에 잔류 염소, 용존 유기탄소(TOC), 색도 및 미·악취 물질을 제거하기 위해 GAC/PAC 대량 구매가 필요합니다. 정수 수질 및 막 보호와 직결되는 정기적인 컨테이너 단위 구매 품목입니다.

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 (4)
Activated Carbon (GAC/PAC)
CAS 7440-44-0
무기 충전제 및 안료
착색 / 안료
1362 (CARBON, ACTIVATED) · Class
In catalog. High surface-area carbon physically adsorbs dissolved organics, color and taste/odor molecules; surface reactions also reductively dechlorinate free chlorine

activated carbon (GAC), graded by iodine number
CAS 7440-44-0
무기 충전제 및 안료
착색 / 안료
1362 (CARBON, ACTIVATED) · Class
Higher iodine-number grades give more micropore volume for trace-organic and TOC polishing in backwashable fixed beds
융점:Melting point equals > 3500 °C   끓는점:Sublimes at 3642 °C; triple point (graphite-liq…   밀도:The apparent density of beech charcoal is 0.45 …

Powdered activated carbon (PAC)
CAS 7440-44-0
무기 충전제 및 안료
착색 / 안료
1362 (CARBON, ACTIVATED) · Class
Fine particle size gives fast adsorption kinetics for slug-dosing seasonal taste/odor or spill events into the process stream

Catalytic / acid-washed carbon
CAS 7440-44-0
무기 충전제 및 안료
착색 / 안료
1362 (CARBON, ACTIVATED) · Class
Surface-modified carbon catalyzes oxidation of hydrogen sulfide and chloramine that ordinary GAC removes poorly; acid washing lowers ash and metal leaching
