Abstract:
Background and Objectives: High rate algal ponds (HRAP) is a promising technology in wastewater treatment and algal biomass production. It is considered as a cost-effective as it covers the capital and operation costs by recovers of water and nutrient which is beneficial in agriculture. Also, algal biomass produced could be used for the production of valuable raw materials. The aim of this study was to evaluate the application feasibility of HRAP in Egypt for economical and low energy wastewater treatment combined with potential production of algal biomass for biofuel and value added compounds. Materials and Methods: The integrated system applied was Facultative Pond (FP)+HRAP+Tube Settler (TS). The FP effluent was fed to HRAP which breakdown the soluble organic substances, provides good natural disinfection and produce algal biomass. Finally, HRAP effluent fed to TS which remove about 60% of TSS. Results: The results indicated that the integrated system was efficient in removing COD, BOD and TSS, average removal percentages were 61, 66 and 65%, respectively. The HRAP increases the algal biomass growth, where, the average algal biomass was 27g m2/day. It was cleared that FP and HRAP ponds proved to be an excellent process for bacterial removal; the coliform group removal was ranging between 3 and 4 logs. Conclusion: The results proved that the final effluent characterization is complying with Egyptian Ministerial Decree for reuse.
