Determining the Efficacy of Wastewater Treatment
One of the key parameters in measuring samples of wastewater is the Chemical Oxygen Demand (COD). It is a measure of the oxygen demand of biogradable pollutants plus the oxygen demand of non-biodegradable oxidizable pollutants. COD is an indication of the relative oxygen depletion effect of wastewater. The water is considered to be less polluted if the COD level is lower.
Increasing the Oxidation Capacity of Wastewater
To reduce the contamination effects in wastewater, SIF Technologies could provide superior technologies to enhance the conventional process of wastewater management. In 2007, SIF Technologies implemented the DPA system in the wastewater treatment facility of a leading consumer manufacturing company located in Southeast Asia. Test results proved that SIF’s proprietary technology has created positive impacts for the overall wastewater management process.
Oxidation / reduction potential (ORP) is the tendency of a chemical species to acquire electrons and thereby be reduced. A chemical species with more negative reduction potential has greater tendency to lose electrons to a new species and thereby become oxidized. ORP value has become more negative than pre-treatment state, which implied that the oxidation capacity has been enhanced. The level of Chemical Oxygen Demand (COD) was also significantly reduced. This indicated that the pollution level of wastewater has also been reduced greatly, even without the use of other forms of chemicals.
