Public health and safety concerns have traditionally been the main reasons for resisting waste water reuse for fish farming. Potential adverse health effects in such applications could be avoided if the waste is sufficiently treated before reuse. In a full scale demonstration study in Suez, Egypt, about 400 m3/d of raw sewage were treated using a multi-compartment stabilization pond system, for a total residence time from 21-26 days. The treated effluent conformed to WHO guidelines and was used for rearing two types of local fish (tilapia and gray mullet). The produced fish were subjected to an extensive monitoring program. Bacteriological examination revealed that in all samples the fish muscles were free of bacterial contaminants. Nevertheless, low levels of Escherichia coli andAeromonas hydrophila, were isolated from the surface of the fish. Salmonellae, shigellae and staphylococcus aureus were absent from the surface of all the fish sampled. In addition, toxic metals (Pb, Cu, Zn, and Cd) were found to be at much lower levels than the international advisory limits for human consumption. It is concluded that fish reared in the treated effluent at Suez Experimental Station is (a) suitable for marketing for human consumption, and (b) it's quality is equal or better than fresh water fish in Egypt.

African Experience

Membrane processes have recently been applied much more extensively by South African industry. A number of the older plants have suffered from fouling problems, sometimes brought on by changes in the feed stream. Newer installations are tending to apply the techniques of Cleaner Production to more closely integrate the membrane process into the manufacturing process and to reduce the size of the installation. There has been a trend to investigate methods of using the brine in place of discharging it to the environment. Membrane related research is still very active and a range of current initiatives is provided.

Experiments with a falling film reactor were conducted to examine the potential of the freeze concentration to reuse municipal waste water. The waste water was recycled in the falling film reactor while ice films were frozen on the cooled inner walls. Pure water was removed from the solution by crystallization, and the liquor was concentrated. Finally, the separated clear ice was melted. Various parameters such as conduction, TOC, COD and NH4-N of the melted ice and waste water concentrate were measured. A clearance efficiency up to 99% was observed for municipal waste water and 91% for high concentrated waste water. In addition, particulate solutions were removed from the aqueous phase as efficiently as the organic and inorganic solutes.

The objective of the study was actually the investigation of the effect of various treatments on the ability of urine in absorbing greenhouse gases. Urine alone or mixed with olive-oil-mill waste waters (O), poultry litter (P), or sewage sludge (S) was used on the absorption of CO2 and NOx from diesel exhaust. The absorption coefficient (0.98–0.29 g CO2/grNH4) was similar to other solvents such as ammonia and amines. The ranges of CO2 absorption(1.7–5.6) g/l and NO reduction (0.9–3.7) g/l in six hours indicate that on average 20 litres of urine could be needed to capture CO2 and NOx vehicle emissions from each covered kilometre. The best results of CO2 absorption and NOx reduction were for urine mixed with O, P and urine alone. These wastes could be used to capture CO2 and NOx from automotive diesel engines to reduce gas emissions. The proposed strategy requires further research to increase CO2 absorption and reduce the risks associated with waste-water reuse.
