| Abstract | ||||
| The efficiency of the current sewage treatment plant in Buraydah City (Central Region of the Kingdom of Saudi Arabia) was studied during three consecutive years (1995/1996, 1996/1997 and 1997/1998) by considering some of the physicochemical and bacteriological characteristics of effluent sewage that determine its suitability for irrigation. Processing of the available data and thereafter comparing them with the locally and internationally acceptable quality standards for unrestricted and restricted irrigation revealed that 1) the expected yearly average volume of treated effluent varied from 19.2x104-26.4x104 m3. 2) the effluent under study is unacceptable for irrigation reuse with respect to its mean BOD level (range 87-99 mg L-1), mean COD level (range 114-161 mgL-1), mean total suspended solids content (range 98-104 mg L-1), and mean alkalinity level (range 334-365 mg L-1). The data indicated that the efficiency of reducing the levels of the studied parameters using the currently adopted treatment, is low. 3) electric conductivity (EC mmhos cm-1) and pH value of effluent are within the acceptable quality limits and are not expected to pose severe problems. 4) high fecal coliform count (range 3.3x104–40x104 MPN 100mL-1) and high total coliform count (range 4.5x104 -71x104 MPN 100mL-1) were evident thus indicating a low efficiency of microbial removal which renders the effluent unacceptable for unrestricted and restricted irrigation reuse because of public health hazards as well as evolution of offensive smell to the neighborhood. | ||||
