The meat industry is characterized by high water consumption. Since this wastewater is highly loaded, it should be thoroughly pre-treated prior to its discharge into receiving water. Our investigations revealed that a hybrid system of ultrafiltration and reverse osmosis is a promising purification method. Its application resulted in a 100% and 98.8% removal of phosphorus and nitrogen compounds,...

The purpose of this study was to determine whether continuous flow SBR could provide efficient pollutant removal in domestic wastewater. The experiment was carried out using a pilot scale at Tehran University of Medical Sciences and in wastewater treatment plant. The results showed that 97.7% of BOD removal, 94.9% COD removal, 85.4% TKN removal, 71.4 % TN removal, 55.9% TP removal and 99% TSS r...

This paper focuses on the Call Control for the establishment and release of isochronous calls within the DAMS network (ESPRIT project #2146), a distributed ISDN PBX over an FDDI-II backbone optical ring that supports both isochronous and asynchronous traffic generated by ISDN terminals, LAN terminals, and Bandwidth On Demand (BOD) terminals. After a general overview of the DAMS network architec...

The discoloration of a biologically pretreated waste water stream from a molasses processing by ozonation and two advanced oxidation processes (O3/H2O2 and 03/7-irradiation, respectively) was studied. Colour removal occurred with all three processes with almost the same efficiency. The main difference of the methods applied was reflected by the BOD increase during the discoloration period. By o...

The redox potentials of the multicopper redox enzyme bilirubin oxidase (BOD) from two organisms were determined by mediated and direct spectroelectrochemistry. The potential of the T1 site of BOD from the fungus Myrothecium verrucaria was close to 670 mV, whereas that from Trachyderma tsunodae was >650 mV vs. NHE. For the first time, direct electron transfer was observed between gold electrodes...

The Western Cape Provincial Government initiated the collaborative Burden of Disease (BOD) Reduction Project to reduce its burden of disease and promote equity in health. 1 This shift in thinking from facilities to a population-based approach to health demonstrates increased awareness about the crucial role of upstream factors on population health. It resonates with the recommendations of the W...

Well-established biodegradation tests use biogenously evolved carbon dioxide (CO(2)) as an analytical parameter to determine the ultimate biodegradability of substances. A newly developed analytical technique based on the continuous online measurement of conductivity showed its suitability over other techniques. It could be demonstrated that the method met all criteria of established biodegrada...
