Kelin Activated Carbon in Wastewater Treatment

Specialized activated carbon product designed for a wide range of water treatment duties. Products in this range are compliant with international standards, including NSF, EN and AWWA. Moreover, they also meet the requirements of the Food Chemicals Codex. This ensures a high standard of performance in potable, process and waste water applications.

Wastewater treatment plants often deploy activated carbon to achieve a purification level that allows the treated water to be discharged into environmental water bodies. Our comprehensive range of Kelin granular and powdered activated carbons effectively remove:

• Organic impurities (COD)
• AOX (Adsorbable Organic Halides)
• Micropollutants, e.g. pharmaceutical and personal care residues, pesticides, endocrine disrupting compounds
• Aromatic compounds, e.g. BTEX (benzene, toluene, ethylbenzene and xylene), phenol
• Colors
• Odors

Granular Activated Carbon (GAC) for Wastewater Treatment

When treating the wastewater with this type, the liquid is made to percolate through a bed of granular activated carbon. Generally the filters (also called contractors) made for using this type of activated carbon are fixed-bed with down flow column – either a steel column or a steel or concrete rectangular tank. Contaminants are adsorbed as the liquid feeded from the top gravitates. Lately new style contractors have come up: expanded bed and moving bed. Regener ability is one of the most significant features of granular activated carbon. The handling is simple and operational costs are lower with this type.
