Different Types

Pilot-scale rock filters were constructed at the outlet of a large waste stabilization pond facility in Jordan. Their viability in upgrading the ponds' effluent was studied over a period of eleven months. This was done through studying the efficiency of four different types of locally available inexpensive materials placed in six filters and configured in three trains. The efficiency of each filter and the three combinations was evaluated. Results show that the filters can reduce the ponds' effluent content of TSS and BOD5 by 60%, TFCC by a maximum of 94% and T-P by 46%. This was achieved with a loading of 0.033-0.044 kgTSS/m3.d at an average temperature of 25 °C. Of the four media, the wadi gravel medium (3-23 cm) performed best. It was concluded that rock filters constitute a promising upgrading technique for pond effluent.

Biochemical Degradation

Pilot scale “Waste Stabilization pond” was evaluated for treating high quality waste water using aerobic process. The method involved the measure of the molecular oxygen utilized during a specified incubation period for the biochemical degradation of organic matter and oxygen used to oxidize inorganic material. Operation of the pond involved engineering construction to reduce the risk of soil and groundwater contamination. Calibration of the model using laboratory tests showed BOD for 5, 10 and 15 days as 101.9mg/l. 273.3mg/l and 426mg/l respectively. Pond efficiency was 76.19%. The design experience and post design results provided knowledge about the efficiency of a waste stabilization pond and the basis of recommendation and practice in developed cities.
