ASSESSING THE FILTRATION PROCESS OF MEDIA FILTERS FOR MODERN IRRIGATION SYSTEM USING DIFFERENT MEDIA
Water Management Research Institute, National Water Research Center.
Abstract
The media filter is a fundamental techniques for removing any organic sediments as algae, weeds and bacteria or inorganic sediments as clay, sand and solid chemicals that may be present in the water and could cause nozzles and emitter clogging.
Innovated filter unit with filtration media consists of foam granules and polyethylene granules comparison with sand or gravel media filter.
Worth Mentioning that the foam granules media was resisting of mold, bacteria decomposition and water salinity but unresisting of some acid decomposition. Also, the polyethylene granules media was resisting of mold, bacteria, water salinity and acid decomposition.
Field experiments were carried out, at Al-Mansouria farm-Giza Governorate and Al-Bustan fields Behaira Governorate to evaluate the performance of the designed innovated filters with a foam granules media and polyethylene granules media. The aim of this study was innovated media filter unit consisting to substitute media of sand or gravel media was high sufficiency and lesser coset.
The experiment show that the flow rate is started to decrease and the flow rate reduction percentage is started to increase when the pressure losses increased from 0.6 bar pressure losses until 1.0 bar pressure losses. Also, the results show that the water consumption during the flushing process and the time consumed of filtering volume unite are started to increase when the pressure losses increase from 0.6 bar until 1.0 bar pressure losses. Eventually, the sedimentation concentrate and the filtration efficiency are started to decrease when the pressure loss increase from 0.6 bar until 1.0 bar until 1.0 bar pressure losses. The results show that the use of foam as media filter is recommend because of its high performance regarding increase filtration efficiency at 80.03% with Nile water and 78.69% with waste water and decrease the cost of cubic meter of filtration technically and economically.
