Title: Assessment of wastewater from vegetable oil & soap factories
Author: Ahmed, Alrasheed Ali
Abstract: In most developing countries (Sudan is a good example) the vegetable oil and soap industry constitute an important agro-industrial activity that could be the basis for future industrialization and could contribute significantly to the economics of those countries. However, effluents from vegetable oil and soap factories in general, and in Khartoum North, Omdurman industrial area in particular, create serious problems with regard to the environment within the factories, in the sewerage, finally in the treatment plant at El Haj Yousif and on Land. The purpose of this study could be summarized in the following: - (1) To determine the sources of wastes in vegetable oil and soap factories. (2) To determine the characteristic of wastes (quality and quantity). (3) To determine pretreatment of wastes from vegetable oil and soap factories to levels acceptable for discharge to municipal works and on land. (4) To investigate the possibility of recovery of the valuable byproduct from the wastes. In order to achieve the above objectives two factories have been chosen to represent the majority of vegetable oil and soap factories in Khartoum north and Omdurman industrial area. These factories are: - (1) Soap, allied industries company in Khartoum North. (2) EL Tawfig Soap factory in Omdurman. After comprehensive study and laboratory research, it was found that the effluents discharged from the studied factories, are above allowable limits for discharge to the public sewer and on land. However it was found that these effluents could be treated by physical process that make them fit for discharge to the public sewer and on land, and also a valuable byproduct (fatty acids) could be recovered from the effluents, which can be used as animal feed.
