DEGRADATION — CHEMICAL OXYGEN DEMAND
4 Chemical Oxygen Demand, an indicator of chemical pollution.
The chemical oxygen demand should be a mean of at least three measurements.
The chemical oxygen demand (COD) is determined according to method C.6.
Water quality — Determination of the chemical oxygen demand
20% reduction in chemical oxygen demand (COD) emissions;
Final discharge of Chemical Oxygen Demand (COD) (a) (in thousands of
DOC(dissolved organic carbon) and TOC (total organic carbon), or COD (chemical oxygen demand
DOC = dissolved organic carbon; COD = chemical oxygen demand).
Recommended parameters are: COD (chemical oxygen demand), nitrogen and phosphor.
The method includes the removal from effluents of organic compounds that result in BOD, COD and toxicity by the use of reverse osmosis.
Water quality - Determination of the chemical oxigen demand.
Water quality - Determination of the chemical oxigen demand.
The reduction of eolor and other parameters like BOD, COD and TDS of the effluent takes place by simple adsorption technique.
A method for reducing recalcitrant chemical oxygen demand (COD) of a liquid in a water system is provided.
The invention relates to a means and a method for photometrically determining the chemical oxygen demand of chloride-containing samples.
equipment for the determination of the total organic carbon concentration (TOC) of water or equipment for the determination of the chemical oxygen demand (COD
Moreover, disposal of the DMSO increases the chemical oxygen demand (COD) load on the effluent treatment plant (ETP).
The emulsions have a low COD value and are safe, storage stable, and generally applicable.
Furthermore the waste water presents a chemical and physical composition that makes it easily purified, thanks to the balanced relationship between the so-called Chemical oxygen demand (COD) and the Biological need of oxygen (BOD).
The process also enjoys reduction in chemical oxygen demand and total solid load compared to conventional process
The dissolved organic carbon concentration (DOC) or soluble chemical oxygen demand (S-COD) of water in the tank is measured.
These standards are: chemical oxygen demand COD = 180mg O2/litre, biological oxygen demand after 5 days BOD5 = 70 mgO2/litre, total suspended solids TSS = 60 mg/litre.
The electrodes offer superior removal of chemical oxygen demand (COD) and are thus useful in the remediation of wastewaters.
Furthermore the waste water has a high biological oxygen demand (BOD) and the high use of caustics also means a high chemical oxygen demand (COD) from waste water.
