Sewage Treatment

Learn More

Sewage treatment is a line of action that proceeded to remove contaminants from sewage water (runoff effluents and domestic effluents). It includes a physical, chemical, and biological process to remove physical, chemical, and biological contaminants. Its objective is to fabricate the environmentally – safe treated water and a suitable for disposal of solid waste or reuses as manure.

Sewage Treatment is designed using the following methods.

  • Advanced Immobilized Cell Reactor Technology
  • Extended aeration with Activated sludge process
  • Membrane Bio-Reactor (MBR) Technology
  • Fluidized Bed Bio-Reactor Process (FBBR)
  • Physio – Chemical processes

Three stages of Sewage Treatment

Primary Treatment

Primary Treatment comprised of temporarily holding the sewage in a quiescent basin where heavy solids can settle to the bottom while oil, greases, and lighter solids float to the surface. The settled and floating materials are unfastened and endure the liquid may be discharged or subjected to secondary treatment.

Secondary Treatment

Secondary treatment pulls out dissolved and suspended biological matter. Secondary treatment is typically performed by indigenous, water-borne micro-organisms in a managed habitat. Secondary treatment may require a separation process to remove the microorganisms from the treated water before discharge or to lift it to the tertiary treatment. Using the latest technology we extensively use the MBR technology for the secondary treatment to suits the client’s essentials to reduce the plants’ layout.

Tertiary Treatment

Industrial wastewater accommodates diversified impurities & so grounds the exceptional chore for this task. Furthermore, the emission limit for industrial effluent is constantly being tightened up. Closed circuits and product recovery in various production processes are becoming an increasing priority among manufacturing companies. These measures represent an additional contribution to the protection of aquatic ecosystems and also possess huge cost-cutting potential. The treatment process contains mechanical, biological, and physic-chemical process steps.

In the case of biological, anaerobic wastewater treatment, we employ conventional process and space savings, high-performance re-actors such as the world’s most frequently used UASB process. Another system is utilized under the characteristics of the wastewater. For maximizing the cleaning requirements, we employ a membrane process with submerged or external membranes. The Edges to adopt this method rescue the liquid resources & empirically results in zero discharge of wastewater.
