Sewage Cleanup Service plays a pivotal role in maintaining public health and safeguarding the environment. It involves the removal, transportation, and treatment of wastewater to render it safe for discharge back into the natural environment. ### Sewage Treatment Process The sewage treatment process entails several stages: * **Primary Treatment:** Physical processes such as screening and sedimentation remove solids and debris. * **Secondary Treatment:** Biological processes utilize bacteria to break down organic matter. * **Tertiary Treatment:** Advanced processes, such as filtration or disinfection, further purify the water. ### How Clean is Water After Sewage Treatment? The efficacy of sewage treatment is measured by the quality of water discharged after the process. Modern treatment facilities typically achieve a high level of purification, removing: * 99.99% of bacteria and viruses * 95-99% of suspended solids * 90-95% of biochemical oxygen demand (BOD) Treated wastewater meets strict environmental standards, ensuring its safety for discharge into water bodies or for reuse in non-potable applications, such as irrigation. It should be noted, however, that some contaminants may persist in trace amounts.
Following sewage treatment, the resulting water is significantly cleaner and safer than the raw wastewater. However, it is important to note that while it has undergone a rigorous purification process, it may still contain trace amounts of certain contaminants. Therefore, it is generally not recommended for direct human consumption without further treatment.
