Dechlorination
Removes free chlorine to protect downstream membranes, resins, and sensitive process steps. Design is driven by contact time (EBCT) and required residual.
Product Water Treatment
Activated Carbon (Granular)
Granular activated carbon (GAC) media for fixed-bed filtration: dechlorination (free chlorine removal), taste/odor control, and adsorption of dissolved organics for continuous polishing and RO pretreatment.

Selection is driven by target contaminants and operating conditions (EBCT/contact time, pressure drop limits, and backwash). Share your vessel details and KPI targets for a correct grade match.
Overview
Granular activated carbon is an adsorption media used in packed beds to remove chlorine, taste/odor compounds, and dissolved organics. In RO pretreatment and process-water polishing, GAC is commonly installed in pressure filters (or gravity vessels) to provide stable, continuous performance.
Taste & odor control
Adsorbs odor-causing organics and improves aesthetic quality in potable/process water polishing trains.
Organic adsorption
Removes dissolved organics that contribute to color, TOC/COD loading, and downstream fouling. Pore structure selection matters.
Base material options (selection cue)
Choose the grade family first, then size and durability.
Coconut shell
Typically higher hardness/abrasion and strong performance for many taste/odor applications. Often preferred where low fines and durability are priorities.
Coal-based
Broad pore distribution; often selected for general municipal/industrial adsorption duties. Available across multiple mesh sizes.
Wood-based
Often higher macroporosity; considered for certain color/large-molecule organics depending on site data.
Final selection should be validated against your influent profile, target KPIs, and operating limits (pressure drop/backwash).
Applications
Typical usage patterns. Tell us your process and constraints and we’ll align the right grade, mesh, and hardness.
- Dechlorination prior to RO / NF membranes
- Taste and odor control (continuous polishing)
- Organic removal and finishing filtration (fixed-bed adsorption)
- Pretreatment for process water in food/beverage, utilities, and industrial plants
Operating concepts that drive performance
These determine grade selection and bed sizing.
EBCT / contact time
Empty Bed Contact Time (EBCT) is a key design lever for adsorption and dechlorination. Higher EBCT generally improves removal but increases vessel size.
Pressure drop
Finer mesh increases adsorption kinetics but may raise pressure drop and backwash demand. Mesh must match hydraulics and service goals.
Backwash durability
Hardness/abrasion affects fines generation and bed stability in backwash service—critical for long run-times and clear effluent.
Commissioning & maintenance notes (summary)
Site SOP and equipment design always take priority.
- Pre-rinse/backwash is typically required to remove fines and stabilize turbidity
- Backwash rate must be compatible with media size and vessel design to avoid media loss
- Service life depends on influent loading and breakthrough criteria; monitoring strategy should be defined
If you share your monitoring approach (chlorine residual, UV254, TOC, odor complaints), we can propose a practical replacement strategy.

Quick selection cues
What operators typically optimize for stable operation.
- Dechlorination: sufficient EBCT/contact time and reliable monitoring of residual at outlet
- Hydraulics: mesh size vs. pressure drop; avoid excessive fines carryover at startup
- Backwash: hardness/abrasion to reduce fines generation and extend life
- Operations: defined breakthrough criteria and replacement/regeneration plan
