Parameter On Waste Water Control
Waste treatment should be controlled by the limitation on Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD) and for solid waste that dissolved on water should be measured by Total Suspended Solid (TSS) and Total Dissolved Solid (TDS).
Biochemical Oxygen Demand (BOD5) refers to the amount of oxygen that would be consumed if all the organics in one liter of water were oxidized by bacteria and protozoa or the amount of dissolved oxygen consumed in five days by biological processes breaking down organic matter.
Chemical oxygen Demand (COD) is used as a measure of oxygen requirement of a sample that is susceptible to oxidation by strong chemical oxidant or is a measure of the oxidizability of a substance, expressed as the equivalent amount in oxygen of an oxidizing reagent consumed by the substance under fixed laboratory conditions.
Total Suspended Solids (TSS) is a measure of the mass of fine inorganic particles suspended in the water that can be trapped by a filter.
TSS can include a wide variety of material, such as silt, decaying plant and animal matter, industrial wastes, and sewage. High concentrations of suspended solids can cause many problems for stream health and aquatic life.
Total Dissolved Solids (TDS) are the total amount of mobile charged ions, including minerals, salts or metals dissolved in a given volume of water.
AVG – Average is mean values of data collected within certain period of time for regulated parameter.
All of those (BOD, COD, TSS, TDS) are expressed in units of mg per unit volume of water (mg/L), also referred to as parts per million (ppm).
