Reduction of Scale Formation in Irrigation Nozzles Using Natural Coagulants—An Experimental Study Report
摘要
India’s most water-intensive business, agricultural irrigation uses over 85% of the country’s water supply. More than 70% of all freshwater usage is accounted for by cultivation, which is the major user of good quality water worldwide. Equipment use can save major part of water and can be operated manually or automatically. The two most significant factors influencing agriculture are availability of water and quality of water. The most important maintenance concern with micro-irrigation is emitter blockage, which accelerates drip irrigation system ageing and is made worse by subsurface irrigation systems. Among the most significant issues in agriculture, when it comes to equipment operation, management, and the main aim of sustainable production of crop, the drip irrigation system’s effectiveness has an impact on the efficiency of the system and, which in turn, will have major financial repercussions. When very biologically active water is used for agriculture, blockage from microorganisms is common, and it is will worse by the presence of iron, manganese, and sulphur dioxide. Drip irrigation may become clogged due to scale formation if the water contains a high concentration of certain elements and has a pH level that is higher than the acidic range. Efforts to reduce the formation of scales in drip nozzles had carried out in this work. A pilot-scale sedimentation tank model with tube settlers was designed and natural coagulants were used to reduce the hardness of water predominantly. The detention time was lowered to as low as 20 min when compared to conventional sedimentation tanks. Average reduction in hardness of 70–80% was witnessed.
