This primary batch of sludge contains nearly 50% of suspended solids within wastewater. Sewage sludge is the solid, semisolid, or slurry residual material that is produced as a by-product of wastewater treatment processes. Sewage treatment is carried out in two stages. What is Primary Immune Response? From the Primary Clarifiers, the wastewater flows into large, rectangular tanks called Aeration Basins, where a biological treatment called the “activated sludge process” occurs. 3. 4. 2. it does not possess flocs of decomposer microbes. In activated sludge system, the primary efflu­ent is taken to aeration tanks. The digesters can either be rectangular or round. The sludge is treated as required for utilization or disposal, and additional treatment of effluent may be needed to accommodate specific water reuse opportunities.

The key difference between primary and secondary valency is that primary valency is the oxidation state of the central metal atom of a coordination complex whereas secondary valency is the coordination number of the central metal atom of a coordination complex. Some of the solids collected in the secondary clarifier (return activated sludge) are sent back to the aeration tank. The terms primary and secondary valency fall under coordination chemistry. Differentiate primary and secondary sex organs is:-The primary sex organs, or gonads, consist of the ovaries and testes.These organs are responsible for producing the egg and sperm cells (gametes), and secretion of hormones whereas secondary sex organs help in conduction of male gamete (sperm) and female gamete (ova).
