Product Overview
GAC S is an acid-washed coal-based granular activated carbon designed for standard-duty ultra-pure water and food-grade water treatment. Manufactured from premium bituminous coal through carbonization, steam activation, and acid washing, it achieves a pH of 5–8 with iodine adsorption exceeding 900 mg/g and methylene blue above 150 mg/g.
Positioned as the standard acid-washed grade in our coal water treatment series, GAC S provides reliable organic removal and dechlorination for applications where premium SQ-grade capacity is not required. The acid-washed surface ensures minimal pH drift and reduced extractable content compared to standard non-washed coal carbons.

Key Application Areas
- Ultra-Pure Water Treatment — Polishes deionized water for electronics, laboratories, and power generation where moderate organic removal and pH stability are required.
- Beverage Processing Water — Treats ingredient water for breweries, bottling plants, and food manufacturing, supporting consistent product quality.
- Point-of-Entry (POE) Systems — Provides whole-building protection against chlorine and organics in residential and commercial water supplies with neutral pH effluent.
Key Advantages
- Cost-Effective Acid-Washed Performance: pH 5–8 and reduced ash deliver acid-washed benefits at a practical price point for standard ultra-pure and food-water systems.
- Proven Dechlorination Kinetics: Iodine >900 mg/g ensures rapid chlorine and chloramine reduction, protecting downstream RO membranes and ion exchange resins.
- Dual Mesh Options: GAC 830S (1.4–1.7 mm) suits high-flow POE; GAC 1240S (1.2–1.4 mm) provides enhanced contact for polishing applications.
- Stable Water Chemistry: Acid washing prevents the alkaline pH spikes common in standard coal carbons, reducing the need for downstream pH adjustment.
