Diagram illustrating sewage treatment using the activated sludge process. Raw sewage passes through screens and grit chambers in primary treatment, then flows to a primary clarifier. The primary effluent enters an aeration tank for secondary treatment, where air is added and activated sludge helps break down waste. The mixture moves to a secondary clarifier, with some sludge returned to the aeration tank and excess sent for disposal. Disinfected secondary effluent is released to surface water or
