Drinking Water Filtration Using Granular Activated Carbon
Granular Activated Carbon (GAC) is commonly employed as an adsorption media in many surface water treatment plants. Most plants, however, also rely on GAC to provide effective filtration, as turbidity reduction is an essential element in maintaining desired water quality.
----- Wastewater treatment with GAC consists of the carbon contact system and the carbon regeneration system. Activated carbon removes soluble organics from water in three steps. The first step is the transport of the dissolved substances to be removed (solute) through a surface film to the exterior surface of the carbon.
Drinking Water Treatability
Activated carbon is an effective adsorbent because it is a highly porous material and provides a large surface area to which contaminants may adsorb. The two main types of activated carbon used in water treatment applications are granular activated carbon (GAC) and powdered activated carbon (PAC).
About our Granular Activated Carbon (GAC) 75 years after its founding, Calgon Carbon remains on the cutting edge of innovation, offering an exceptional range of granulated activated carbon applications and reactivated carbon formulations engineered specifically for the purification of water, air, liquids and gases.
Granular activated carbon as an adsorption and filtration
About granular activated carbon. Granular activated carbon (GAC) is a hybrid mixture of a wide variety of graphite platelets that are interconnected by nongraphitic carbon bonding. The adsorptive capacity of GAC makes it ideal for removing a variety of contaminants from water, air, liquids and gases.
Should drinking water sources be contaminated with endocrine disruptive compounds, they have to be efficiently removed. Activated carbon is commonly used for the removal of micro-pollutants in drinking water treatment (e.g., Zytner, 1992). For design of cleaning processes adsorption isotherms are rough guidelines.
Activated Carbon Filtration - Water Treatment Guide
Granular activated carbon (GAC) is commonly used for removing organic constituents and residual disinfectants in water supplies. This not only improves taste and minimizes health hazards; it protects other water treatment units such as reverse osmosis membranes and ion exchange resins from possible damage due to oxidation or organic fouling.

- What is high-purity poly-aluminum chloride (PACL)?
- Poly-aluminum chloride (PACl) is one of the common coagulants for water and wastewater treatment. A new Chinese national standard of PACl has been implemented, where the concentration of insoluble substances, iron and heavy metals is to be controlled strictly, then researches on the preparation of high-purity PACl are needed.
- What is polyaluminum chloride PAC?
- Polyaluminum chloride PAC is a widely used chemical compound that finds its application in various industries, primarily for water treatment. In this blog post, we will delve into the different grades of PAC, the production methods, and its specific uses in different sectors.
- What is Poly Aluminum Chloride used for?
- Poly aluminum chloride is used for water treatment. With the properties of adsorption, aggregation and precipitation, it is an excellent coagulant in sewage treatment, industrial wastewater treatment, drinking water treatment, and circulating water treatment, etc. It is also used in the papermaking industry.
- Which polymers are used to make high-purity PACL?
- After PACl was prepared, the polymers with a sulfydryl group and modified PAM were added into the conventional liquid PACl, this not only removes iron significantly, but also accelerates the sedimentation of insoluble suspended matter. The properties of high-purity PACl synthesized by bauxite and calcium aluminate are shown in Table 3.
