ABSTRACT
Slaughterhouses generate considerable quantities of wastewater due to the huge amount of blood produced from slaughtering process and the need for cleaning and hygiene of meat. Due to the extraordinary content of organics and minerals, wastewater from slaughterhouses needs special care and treatment for safe disposal to the environment. Currently, wastewater from slaughterhouses in the Gaza Strip is discharged to the public networks without any treatment burdened central wastewater treatment plant, where partially treated effluent discharged to the sea. The aim of this research is to characterize the wastewater from Gaza slaughterhouse to identify the best approach for treatment. Samples from the slaughterhouse were collected during working hours and analysed for physical and chemical parameters. The pH, EC, DO, BOD, TSS, COD, Ammonia Nitrogen and TKN account for 7.1, 3300 μsm, 1.95, 2350, 3500, 4502, 30 and 154 mg/l, respectively. Wastewater from Gaza city slaughterhouse is within the range in comparison to other wastewater from slaughterhouses all over the world.
