Design, Construction and testing of Hydro cyclone Water Filter for Blue Nile Water Filtration

Abstract

This study conducted at the Department of Agricultural Engineering, College of Agricultural Studies , Sudan University of Sciences and Technology 2015 – 2016.The main objective of this study is to design , construct and test a model for a hydro cyclone irrigation water filter to be used in filtration of Blue Nile water for modern pressurized s irrigation systems. The hydro cyclone was constructed from locally available materials. The local cost did not exceed 2610 SDG .The inlet and outlet pipes diameter were two inches. The discharge capacity of the model was 5900 l/h. The results obtained from the model were very satisfactory since it was complying with irrigation water silt load standards adopted by FAO (2 gm/l).Two filtration simulations were carried out for silt loads of 6.8gm/l and 8.6gm/l. The results were very close to the Blue Nile filtration results. The slight difference seem to be attributed to extra clay conduct that was achieved to the river silt used in the simulation process. Turbidity levels before and after filtration for Blue Nile water was compared. The results were below the allowable level specified by United Stated Environmental Protection Agency (EAp). This is also true for the two simulation levels. The total cost of the designed and constructed model 2610 SDG which the cost of the imported similar size model filter is 3499 SDG. The final results revealed that the adoption of such a model is quite satisfactory for it well satisfactory technical performance and lower cost.
