Chemical Constituents of Wastewater

Chemical Constituents of Wastewater, the dissolved and suspended solids in wastewater contain organic and inorganic material.

Organic Matter may include carbohydrates, fats, oils, grease, surfactants, proteins, pesticides and other agricultural chemicals, volatile organic compounds, and other toxic chemicals (household and industrial).

Inorganics may include heavy metals, nutrients (nitrogen and phosphorus), pH, alkalinity, chlorides, sulfur, and other inorganic pollutants.

Measurement of Sediment Oxygen Demand (SOD)

Measurement of Sediment oxygen demand (SOD) is a measure of the oxygen demand characteristics of the bottom sediment which affects the dissolved oxygen resources of the overlying water. To measure SOD, a bottom sample is especially designed to entrap and seal a known quantity of water at the river bottom. Changes in DO concentrations (approximately 2 h, or until the [....]

Factors affecting Dissolved Oxygen concentration in water

what are the Factors affecting dissolved oxygen concentration in water Dissolved oxygen (DO) and water temperature are most commonly in situ monitored parameters for surface waters (rivers, streams, lakes, reservoirs, wetlands, ocean, etc.). Dissolved oxygen concentration in milligrams per liter (mg/L) is a measurement of the amount of oxygen dissolved in water. It can be determined with a DO meter [....]

River and Stream Flow Measurement Formula

River and Stream Flow (Discharge) measurement is very important to provide the basic data required for river or stream water quality. The total discharge for a stream can be estimated by float method with wind
and other surface effects, by die study, or by actual subsection flow measurement, depending on cost,
time, man-power, local conditions and so on. The discharge [....]

Bench Study Adsorption Process | Design yourself

The packed bed of adsorbent can be regenerated. If the organic material is volatile, the carbon bed may be regenerated by steaming. However, it is more conven-tional to remove the carbon and reprocess the material through a furnace.In large installations, the furnace is installed as part of the carbon installation; in smaller installations, the carbon may be discarded, or removed [....]
