    Municipal Sewage Industry: Centre of Excellance

    Uploaded by

    Ali Ahsan
    The document summarizes techniques for treating municipal sewage and wastewater from industry. It outlines pre-treatment techniques like physical treatment and chemical/physico-chemical treatment. The major treatment techniques discussed are biological treatment using aerobic and anaerobic systems, as well as chemical treatment methods for toxic wastes. The goal is recycling and reclaiming treated wastes through processes like reverse osmosis, hyperfiltration, and segregating strong from weak wastes.
