SEWAGE TREATMENT – TECHNOLOGIES

COD Measures all organic carbon with the exception of some aeromatics (BENZENE,TOLUENE,PHENOL etc.) which are not completely oxidized in the reaction. COD is a chemical oxidation reaction Ammonia will not be oxidized. Total Suspended Solids Total suspended solids(TSS) include all particles suspended in water which will pass through a filter.

HEPA Air Filtering Systems for Clean Indoor Air

The HEPA Filtration Process. Highly effective HEPA filters remove a wide range of particles from the air with research showing HEPA filters catching up to 99.97% of particles of a 0.3 microns size. As polluted or irritating particles pass through the HEPA filter they become trapped, and remove air full of harmful particles, reactions and odors.

COD Reduction and Removal in Wastewater | Arvia Technology

Chemical Oxygen Demand (COD) is used as a measure of organic pollutants in water and is expressed in milligrams per litre (mg/L) or parts per million (ppm). The most common application of COD is in quantifying the amount of oxidisable pollutants found in water. A COD test can be used to decipher the level of organics in water.
