Operational Modes

Produced water (PW) from oil wells can serve as an alternative water resource for agriculture if the main pollutants (hydrocarbons and heavy metals) can be removed to below irrigation standards. Waste stabilization ponds seem like a promising solution for PW treatment, especially in the Middle East where solar radiation is high and land is available. In this work, hydrocarbon removal from PW in a biological waste stabilization pond was examined at lab-scale followed by an intermittent slow sand filter. The system was run for 300 days and removed around 90% of the oil in the pond, and 95% after the sand filter. COD removal was about 80% in the pond effluent, and 85% after the filter. The system was tested under various operational modes and found to be stable to shock loads. Installation of oil booms and decantation of surface oil seem to be important in order to maintain good system performance over time.

And Performance

The performance of three waste stabilization ponds (WSP) treatment units (lines A, B, C) for a period of two years is presented. The above units were part of a research and demonstration project in North Greece concerning wastewater treatment with natural systems and effluent reuse for irrigation. Line A consisted of a deep anaerobic pond followed by a facultative and two maturation ponds. The anaerobic pond supplied with 120 m3/d was also feeding line B at a ratio 1:3 (line A: line B). Line B had the same design features with line A but with a recirculation of effluent. The third unit fed with primary treated effluent at a rate of 50m3/d from the WWTP of Thessaloniki was consisted of a facultative and two maturation ponds. In the anaerobic pond the BOD5, COD, SS, TC and FC mean reduction was 28%, 42%, 58%, 31% and 36% for the cold period (T<10°C) and 45%, 53%, 72%, 67% and 71% for the warm period (T>10°C) respectively. In line A, the BOD5, COD, SS, TC and FC total reduction was 98%, 89%, 93%, 99.99% and 99.99% for the cold and 98%, 85%, 88%, 99.99% and 99.99% for the warm period. In line B the reduction was 92%, 86%, 88%, 98.5% and 98.82% for the cold and 96%, 88%, 83%, 99.95% and 99.97% for the warm period. In line C the reduction of the same parameters was 92%, 64%, 40%, 99.88% and 99.96% for the cold and 92%, 59%, 22%, 99.99% and 99.99% for the warm period. The effluent quality was further improved with the use of a storage reservoir and a slow sand filter and reused successfully for crop irrigation.

Waste Stabilization

Rotavirus removal in waste stabilization ponds is a relatively slow process: in a series of ten ponds (a 1-d anaerobic pond followed by nine 2-d ponds) its numbers were reduced from 1.4 × 105 per litre to zero, and in an “innovative” series (a 1-day anaerobic pond, 3-d facultative pond, 3.8-d, 3-d and 5-d maturation ponds) from 5.1 × 104 per litre to <5 per litre. Faecal coliforms were better indicators of rotaviruses than was Clostridium perfringens .

Output Load

In 1992, a survey was conducted on the performance of waste stabilization ponds in France. The data selected come from a sample of 178 ponds, with an average capacity of 600 p.e., throughout France. For each plant, one or several input--output load measurements over a 24-h period are available. The average organic load level received is approximately 25 kg BOD/ha.d, representing 50% of the nominal load. The quality of the treated water is presented based on the type of sewerage system feeding the ponds. The results appear dispersed, however; in 70% of the cases the concentrations in COD and BOD on filtered samples are under 120 mg/l and 40 mg/l, respectively, and the concentration in TSS under 120 mg/l (discharge standards in France for waste stabilization ponds). The reductions in nitrogen and phosphorus nutrients are on average from 60% to 70%. The influence of different parameters (sewerage system type, organic load, season, age of plant, etc.) was studied. The results appear noticeably worse when the ponds receive wastewater from a strictly separate sewerage system.
