sludge". Together with the primary sludge from the primary clarification, it forms the sewage sludge. Sewage sludge is a waste product, and is treated by further processes. BASIC KNOWLEDGE.

businesses, and many industries, and deliver it to plants for treatment. Most treatment plants were built to clean wastewater for discharge into streams or other receiving waters, or for reuse. Years ago, when sewage was dumped into waterways, a natural process of purification began. First, the sheer volume of clean water in
which constitutes the bulk of the suspended solids (250 - 400 g m. -3. ). The biological processes which break down this organic matter require oxygen, and the amount of oxygen required is calculated as the wastewater's "biochemical oxygen demand" (BOD). Sewage coming into the plant (influent) has a BOD of between
natural processes that take place in a water body after a wastewater discharge. In a water body, organic matter is converted into inert mineralised products by purely natural mechanisms, characterising the self-purification phenomenon. In a wastewater treatment plant the same basic phenomena occur, but the difference is.

TREATMENT. EFFLUENT. SLUDGE. • ETP (Effluent Treatment Plant) is a process design for treating the industrial waste water for its reuse or safe disposal to the environment. • Influent: Untreated industrial waste water. • Effluent: Treated industrial waste water. • Sludge: Solid part separated from waste water by ETP.
Sewage treatment is a multi-stage process . Different conditions exist in each zone, and wastewater treatment takes place in all three. ? Like most natural environments, conditions inside facultative lagoons . at the beginning of a Wastewater Treatment Plant to remove large trash, sticks, plastic material, rags, ect. It is.
-biological treatment process that removes dissolved organic material from wastewater. The partially treated wastewater from the settling tank flows by gravity into an aeration tank. -liquid mixture (i.e., solids with micro-organisms and water) is sent to the final clarifier.
(physical) treatment and secondary (biological) treatment. Figure 2–1 provides a schematic of a typical wastewater treatment plant. Minimally, wastewater should receive primary (physical removal/settling) and secondary (biological) treatment, which can be followed by disinfection before discharge.
