Intrinsic kinetic tests involve adding relatively high concentrations of organic substrate to small concentrations of acclimated microorganisms so that the COD/VSS ratio typically is greater than 10. Kinetic parameters are then determined by non-linear modeling using well-known relationships between biological growth and oxygen ...

Hydrogen peroxide (H2O2) has been used to reduce the BOD and COD of industrial wastewaters for many years. While the cost of removing BOD / COD through chemical oxidation with hydrogen peroxide is typically greater than that through physical or biological means, there are nonetheless specific situations which justify the use of hydrogen peroxide. These include: Predigestion of wastewaters which contain moderate to high levels of compounds that are toxic, inhibitory, or recalcitrant to biological treatment (e.g., ...

In the oil and gas industry, sodium hydroxide (caustic) is used as a scrubbing agent in various refinery and chemical manufacturing processes. These include, the use in pre-wash columns to remove H2S from the feed to mercaptan removal units (merox units) in refineries. Furthermore, caustic is used to scrub sulphur and carbon dioxide (CO2) from the gaseous product streams during ethylene and propylene production. After use as a scrubbing agent in these processes, the caustic requires treatment and disposal and is ...

Method: An industry was discharging wastewater to a municipal sewer and was suspected of causing problems with treatment at the plant. Samples of the industrial wastewater were collected and oxygen uptake for four dilutions was measured using a CHALLENGE AER-200 aerobic/anaerobic respirometer system. Biodegradation kinetic coefficients were determined using the method described by Dang, et. al. (Res. J. of Water Poll. Control Fed., p. 1711, 1989). Results of the oxygen uptake measurements and kinetic analyses are ...

The petrochemical industry plays a pivotal role in producing versatile and essential materials. However, the process of refining crude oil to create plastics and other materials generates highly toxic waste streams. These waste streams pose significant environmental risks and require substantial treatment costs. From laboratory work we have carried out in-house, we have found that while WAO often falls short of treating these wastes, COD reduction of > 99% is possible in a single step process: AquaCritox ...

The mining industry has the potential to use large amounts of wastewater in its operations. Often times these waste streams contain contaminants that require treatment before the water can be re-used or discharged. Biowater has successfully installed highly efficient biofilm treatment processes including our complete mix fixed film (CMFF®) system to remove BOD/COD, and nitrogen from mining waste streams. Biowater’s technologies, such as our CFIC® process, can produce effluent water quality that is ...

Ozone Oxidizes Organic Matters: Ozone is not only a strong oxidant, but also an effective disinfectant. Ozone oxidation can remove the smell and chroma of water, improve the sensory properties of water, oxidize refractory organic matters, and induce a colloid destabilizing effect, and kill bacteria, viruses and pathogenic microorganisms in water. Most of the chromogenic functional groups in the secondary effluent contain unsaturated bonds. The ozone can destroy the unsaturated double bonds and decolorize the ...

By using ceramic membranes in a tannery, a significant improvement in wastewater quality can be achieved. Highly contaminated wastewater: The tanning process produces highly contaminated wastewater, especially very high COD loads. The so-called COD is the chemical oxygen demand, which is used as a parameter for the degree of contamination of wastewater with organic impurities. This COD content can be reduced with the help of the ceramic membranes in order to relieve the corresponding governmental wastewater ...
