Modification and Advancements in the Traditional Method of Water Purification
India is facing a water crisis and by 2025 it is estimated that India’s population will be suffering from severe water scarcity. International Water management Institute IWMI predicts that by 2025, one in three Indians will live in a condition of absolute water scarcity. Water from the industries, households, etc. has been discharged into the streams without being treated first. Thus, clean water has become a luxury in many water scarce areas. Due to the consumption of contaminated water, people are falling prey to water borne diseases such as cholera, typhoid, etc. The widely used approach to counter such problem has been the use of water treatment plants in cities and towns and water filters in households. However, in a developing country like India water treatment plants and filters in small villages are a rare sight. The major reason for this is the funds required. Also, the processes that are in existence for water treatment are primarily chemical based. With the discovery of processes like phytoremediation, it has become possible to incorporate biological processes in water treatment Piyush Gupta et al. 2012 . Moreover the voids between broken bricks, etc. can be used to trap sediments. Natural coagulants such as moringa oleifera can be used to remove colloidal impurities Abirami. M and Rohini C 2017 . Thus, this assembly of scrap or natural material is not only cheap and easily available but it is also efficient in removing the impurities and improving the BOD, COD and DO levels Nayanthara and Bindu 2017 . This implies that such assemblies can be used to treat water on a household level. This study aims at developing such easy to use and effective water treatment assemblies.
