Investigates anaerobic twostage treatment of tannery wastewater. This results in a mean chemical oxygen demand (COD) removal of 60 per cent for tannery B and more than 70 per cent for tanneries A and C with CODo = 5,710mg l–1 and mean detention time held at 3.5 days. Gas production was small, rating an estimated 75l kg–1 CODo with CODo = 5,710mg l–1. Tests simultaneously the influence of qualit...

Abstract The significant problem is the treatment of landfill leachate characterized by high chemical oxygen demand (COD) and total organic carbon (TOC) presence biodegradation inhibitors such as heavy metals oily substances. For case (pH 7.9, color 1550 mg Pt/L, COD 1880 O 2 /L, TOC 620 mg/L, nitrogen (TN) 220 phosphorus (TP) 6 mg/L metals), effect elevated pressure temperature on decrease val...

Photocatalytic degradation of olive oil mill wastewater from two-phase continuous centrifugation process was studied. A novel photocatalyst with ferromagnetic properties was characterized and investigated. The degradation capacity of the photocatalytic process of olive oil washing wastewater (OMW) and mixture of olives and olive oil (1 v/v) washing wastewaters (MOMW) was demonstrated. At lab-sc...

A two-stage upflow anaerobic sludge blanket (UASB) and sequencing batch reactor (SBR) system was introduced to treat landfill leachate for advanced removal of COD and nitrogen at low temperature. In order to improve the total nitrogen (TN) removal efficiency and to reduce the COD requirement for denitrification, the raw leachate with recycled SBR nitrification supernatant was pumped into the fi...

Treatment of textile wastewater with domestic as co-substrate was investigated in this study. Combined and at different mixing ratios (100:0, 80:20, 60:40) treated under anaerobic reactor. The influence residence time, fraction initial pH were determined view COD color removal. Response Surface methodology (RSM) Box–Behnken design (BBD) employed to determine conditions for higher simultaneous r...

The removal performance of total poly phenols and orthodiphenols (o-diphenols) content in olive mill waste (OMW) was investigated with a three stages cross flow laboratory scale rotating biological contactor (RBC) in the present study. Due to high COD and other pollutant in the original OMW, physico-chemical treatment was effected for COD and other pollutant reduction prior to biological tr...

Leachate pollution is one of the main problems in landfilling. Among the most problematic parameters in stabilized leachate are COD, ammonia, and color. The treatment technology that can be used may differ based on the type of leachate produced. Even after treatment, the effluent characteristics are always hard to comply with the discharge standard. Ozonation is one of the chemical processes th...

Pulp and paper industrial effluent has the foremost role in environmental pollution. The key factor of current study is to determine conjugative effect charcoal (60%) alluvial soil (40%) mixture with laccase enzyme lessen load pulp industry. adsorbent was used for adsorption biological oxygen demand (BOD) chemical (COD), color, lignin effluent. impact pH, temperature, concentration, time on rem...
