Abstract:
Emitter clogging is a serious problem in drip irrigation system. Acid treatment is an effective method for rectification of clogging in which acid is injected in the system with irrigation water for lowering the pH of water. An experimental study was conducted to assess the amount of phosphoric acid to bring down the pH of water to the desired level of 4.0. Twenty two groundwater samples of pH varying from 7.22 to 8.53 were used. The amount of phosphoric acid required for 1000 litre of water varied from 43 ml for sample having initial pH 7.65 to 532 ml for sample having initial pH 8.43. The amount of acid required depends on initial pH and strength of acid used. The major factor governing the acid requirement was HCO3-content of water. Two polynomial equations were developed for estimating the amount of acid required for 1000 liters of water as a function of the initial pH and HCO3- content of water.
