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.
