Pyridine and pyridine based products are of major concern as environmental pollutants due to their recalcitrant, persistent, toxic and teratogenic nature. In this study, we describe biodegradation of pyridine by an isolated consortium/strain under aerobic condition. Batch experiment results reveal that at lower initial pyridine concentrations (1–20 mg l−1),(More)
The effect of some parameters such as the flow rate, initial solute concentration and column bed depth on fluoride removal by fishbone charcoal in a fixed bed column and continuous flow operation was investigated. The useful (or effective) treated effluent volume (corresponding to the desired breakthrough concentration of 1.0 mg/L of fluoride, in this(More)
In this paper, the results of laboratory experiments carried out for the recovery of alum from the sludge obtained from the tertiary treatment of effluent collected from waste stabilization pond have been discussed. The effluent had suspended colloidal impurities. The laboratory test results revealed that at pH 12.0, alum recovery of 79.90% was obtained(More)
Electrochemical oxidation of ammonium (NH4+) at Ti/PbO2 anode in chloride-free and chloride containing aqueous solutions was studied. The experimental results have shown that oxidation of NH4- is ensured only in the presence of chloride. The oxidation of NH4+ is found to follow pseudo first-order kinetics. Bromide in the electrolyte is found to cause(More)
This paper reports the evaluation of the tertiary application of relatively low doses of alum for improving the overall performance and reliability of existing wastewater treatment plants. With this type of system, the additional capability for phosphorus removal is imbibed by simply altering the chemical dose. The study was conducted on wastewater from a(More)
