Wastewater Treatment

Waste Water Treatment Plant

A waste water treatment plant removes contaminants from residential or industrial wastewater so the treated stream and separated solids can be managed through defined routes.

  • Physical treatment
  • Biological treatment
  • Tertiary polishing
  • Wastewater treatment plant with circular clarifiers and aeration basins

    Treatment objective

    Wastewater treatment combines separation, biological conversion and final polishing. The purpose is to reduce solids, organic matter and other contaminants before the water is reused or released through the approved route.

    The plant configuration is selected around wastewater origin, flow, loading pattern, laboratory results and the required final quality.

    Main treatment stages

    1. Preliminary treatment removes coarse debris, rags, grit and free oil.
    2. Primary treatment settles or separates heavier suspended solids.
    3. Secondary biological treatment reduces dissolved and fine biodegradable material.
    4. Clarification separates biological solids from the treated water.
    5. Tertiary treatment adds filtration, adsorption, membranes or disinfection where required.
    6. Sludge treatment concentrates and prepares solids for the selected handling route.

    Treatment technologies

    • Activated-sludge processes
    • Extended aeration
    • Moving Bed Biofilm Reactor (MBBR)
    • Sequencing Batch Reactor (SBR)
    • Submerged Aeration Fixed Film (SAFF)
    • Membrane Bioreactor (MBR)
    • Pressure filtration and activated carbon
    • Reverse osmosis or other membrane polishing where specified

    Applications

    Systems can serve residential communities, commercial properties, institutions and manufacturing facilities. Industrial streams may require dedicated pretreatment before biological stages can operate consistently.

    • Domestic sewage treatment
    • Industrial process wastewater
    • Commercial-building wastewater
    • Institutional and hospital wastewater
    • Treated-water recovery for suitable non-potable uses
    • Upgrading an existing treatment process

    Plant selection and operation

    A practical plant provides access to pumps, blowers, tanks, media, dosing equipment and sampling points. Controls and alarms are coordinated with the operating plan, while testing and monitoring are used to identify corrective action.
