  2. Biochemical oxygen demand - Wikipedia

    en.wikipedia.org/wiki/Biochemical_oxygen_demand

    BOD test bottles at the laboratory of a wastewater treatment plant. Biochemical oxygen demand (also known as BOD or biological oxygen demand) is an analytical parameter representing the amount of dissolved oxygen (DO) consumed by aerobic bacteria growing on the organic material present in a water sample at a specific temperature over a specific time period.

  3. Waste stabilization pond - Wikipedia

    en.wikipedia.org/wiki/Waste_stabilization_pond

    The reactions take place by the joint participation of several microorganisms living within the pond. The organic matter is measured as biochemical oxygen demand (BOD). BOD values in the pond effluent are lower than in the influent, reflecting the removal of organic matter. This pond biome uses organic matter from the wastewater as food.

  4. Streeter–Phelps equation - Wikipedia

    en.wikipedia.org/wiki/Streeter–Phelps_equation

    The Streeter–Phelps equation determines the relation between the dissolved oxygen concentration and the biological oxygen demand over time and is a solution to the linear first order differential equation [1]

  5. Population equivalent - Wikipedia

    en.wikipedia.org/wiki/Population_equivalent

    Population equivalent (PE) or unit per capita loading, or equivalent person (EP), is a parameter for characterizing industrial wastewaters.It essentially compares the polluting potential of an industry (in terms of biodegradable organic matter) with a population (or certain number of people), which would produce the same polluting load.

  6. Wastewater quality indicators - Wikipedia

    en.wikipedia.org/wiki/Wastewater_quality_indicators

    Digestion of this food requires oxygen, so the oxygen content of the water will ultimately be decreased by the amount required to digest the dissolved or suspended food. Oxygen concentrations may fall below the minimum required by aquatic animals if the rate of oxygen utilization exceeds replacement by atmospheric oxygen.

  7. Ministry of Water Resources and Irrigation (Egypt) - Wikipedia

    en.wikipedia.org/wiki/Ministry_of_Water...

    The Ministry of Water Resources and Irrigation is the ministry in charge of managing the water resources of the Arab Republic of Egypt mainly the Nile. It also manages irrigation projects in Egypt, such as the Aswan Dam and Al-Salam Canal. [1] Its headquarters are in Cairo.

  8. Infiltration/Inflow - Wikipedia

    en.wikipedia.org/wiki/Infiltration/Inflow

    Infiltration/Inflow (I/I or I&I) is the process of groundwater, or water from sources other than domestic wastewater, entering sanitary sewers. I/I causes dilution in sanitary sewers, which decreases the efficiency of treatment, and may cause sewage volumes to exceed design capacity.

  9. Mixed liquor suspended solids - Wikipedia

    en.wikipedia.org/wiki/Mixed_liquor_suspended_solids

    By maintaining this ratio at the appropriate level the biomass will consume high percentages of the food. This minimizes the loss of residual food in the treated effluent. In simple terms, the more the biomass consumes the lower the biochemical oxygen demand ( BOD ) will be in the discharge.
