Quality Objective

The physico-chemical treatment of sewage requires the addition of costly reagents. The quantities added are generally proportional to the flowrate treated. Recent progress in pollution detectors now makes it possible to measure sewage concentration continuously. This makes it possible to match the quantity of reagent added to the treated-water quality objective set. COD-SM-Turbidity relations have been determined at various sites. An assessment of the performance of a servocontrol device during the summer of 1983 is presented.

A study was carried out to evaluate the performance of Sewage Treatment Plant in Ghumarwin area and the following conclusions have been drawn. The ranges of physical, chemical and biological characteristics of waste water quality which is in the permissible limits given by waste water/sewage effluent standard as per pollution control board. The results of parameters i.e. pH, BOD, COD, TSS, Oil & Grease after the sewage treatment is under the standards limits. The standards of sewage treatment parameters pH, BOD, COD, TSS, Oil & Grease up to 5.5-9.0, 30mg/l, 250mg/l, 100mg/l and 10mg/l. The results of pH, BOD, COD, DO and SS were 7.0 to 7.5, 18.0 to 22.0 mg/l, 150.0 to 165 mg/l, 5.0 to 6.0 mg/l and 50.0 to 56.0 mg/l, which are within the permissible standard limits . In the present study, all the above parameters were compared with the limits given by Pollution Control Board and it was found that all parameters are with in the acceptable limits. Hence it is concluded that performance of Sewage Treatment Plant is good and in working condition.

Changes of microbial indices of water quality in the Vistula and Brda rivers as a result of sewage treatment plant operationThis paper reports the results of studies of microbiological changes in the water quality of the Vistula and Brda rivers after the opening of sewage treatment plants in Bydgoszcz. The study involved determining the microbiological parameters of water quality. Based on the results obtained, it was found that the quality of the water in both rivers had improved decidedly after the opening of the plants, although an increased number of individual groups of microorganisms was found at the treated sewage outlet from one of the plants.

Sludge Characteristic

The sewage treatment plant of Metabief (East of France) has been monitored during three weeks in winter 1988. The treatment associates a physico-chemical treatment with a biological process of biofiltration. The first step eliminates about 60 % of the organic matter (COD and BOD). The biofliters improve the treatment removing 60 % of COD influent and 65 % of TSS. The process is efficient (N excepted) under conditions of the experiment but nitrification is limited by cold temperatures (< 10°C). Important results related to biological sludge product are presented (sludge characteristic, microscopic data, sludge production). Power consumption of biofliters represents 70 % of the total plant needs. Adequate control of washing cycles and close survey of numerous movable devices are of the utmost importance to guarantee the proper operating of biofliters.

Quality Indexes

A pharmaceutical factory in Wuhan produces many pharmaceutical wastewaters every day. The wastewater raw water quality indexes are: the concentration of COD,BOD5, NH3-N,TP is 300,000mg/L, 200,000mg/L, 450mg/L,900 mg/L ; By the SBBR treatment, the effluent water quality indexes are:750mg/L,350mg/L,1.20mg/L,5mg/L,and the effluent water can accord with Wastewater quality standards for discharge to municipal sewers (CJ 343-2010) and be discharged after treatment in the sewage treatment plant by municipal sewers.

Sewage Outfall

The adult dragonfly fauna and the larval fauna and abundance decrease markedly immediately downstream of the outfall from the Mimosa Sewage Treatment Plant into Bulimba Creek. The adult fauna is substantially restored farther downstream, but the larval fauna and abundance are not. Of the 36 species of Odonata observed at Bulimba Creek, the 10 abundant, essentially stream-dwelling species were most affected by the sewage effluent. Adults of only one of these stream species were found at the most contaminated site, and then only in very low numbers; those of two others were not observed downstream of the outfall. The diversities of both adult and larval dragonfly faunas give a qualitative indication of water quality. Parallels between the distribution or abundance of Odonata and the concentrations of contaminants indicate that chlorine may be the most important toxicant immediately downstream of the sewage outfall in Bulimba Creek.
