dc.description.abstractA study was conducted to develop a filtration technique based upon adsorption to make saline water fit for drip irrigation system. Laboratory studies were performed for selection of effective adsorbent from various adsorbents based on two methods of adsorption i.e. column method and batch method. The lab studies conducted by batch method showed that activated chitosan, silica sand and chitosan of different sizes reduces electrical conductivity (EC), while activated charcoal, zeolite and rice husk ash increases electrical conductivity. Chitosan and silicate were selected based on the performance of lab studies conducted under batch method for further detailed studies to determine optimum contract time. The lab studies conducted by column method showed that silica sand showed better salt adsorption (EC) as compared to chitosan. Batch method was found better adsorption technique than column method in case of adsorbent chitosan for achieves maximum salt adsorption while in case of silica sand the column adsorption performed better results. The adsorbent chitosan from batch studies was able to reduce electrical conductivity (EC) by approx. 24 percent. The adsorbent silicate from column studies was able to reduce electrical conductivity (EC) by approx. 12 percent. Optimum contact time for both batch and column studies was found out to be 30 minutes. Based on results of laboratory studies, the developed filtration technique was based on combination of two adsorption techniques. Firstly the chitosan reduced EC to 24% by batch method and then same treated water was passed through silica sand when reduced EC to 12%. To evaluate the performance of developed filter, a field test was carried out in which simulated saline water having EC of 5 dS/m was passed through two adsorbents with different technologies. The life cycle of both adsorbents were measured by treating simulated saline water with same adsorbents. In case of chitosan the salt adsorption varied from 23.20 % to 20.50 % in six cycles respectively. In case of silica sand the life cycle of adsorbent was six in which the salt adsorption varied from 13.50 % to 9.33 %.en_US
