Sea water contains different kinds of salts. The removal of these salts, and make the water good for drinking to meet WHO standard may sound simple to the human ear but the technique involved is almost like passing a camel through the eye of a needle. Prof Christopher Aderemi Ademoroti of the Dept of Chemistry, University of Benin, Benin City Nigeria, with his technique ‘Aquadem’, recently, desalinated sea water to meet WHO standard for potability (drinking). Science Reporter, STANLEY CHIBUIHEM AMALAHA ,who was with him recently, reports. water is the most important compound to man. It is the second most important substance to all living things, air being the first. Water occupies about 75 percent of the Earth’s surface ,leaving only 25% to land. Yet, regardless of its vastness, drinking water still remains a scarce commodity. This is because most of the abundant types of natural water like oceans, seas, lagoons, rivers, and lakes, contain bacteria, organic remains, mineral salts and other constituent matter which make them not suitable for drinking. In order to correct this imbalance, different techniques have been developed by different scientists for water treatments. But only few have been developed all over the world in the removal of the total content of salt in sea water – a process known as desalination.
This is because the two methods available in the world today namely: “Reverse Osmosis”, and “Dialysis”, are very expensive.Secondly, the quantity of water produced by these methods is very small to meet the required commercial demand. This is one of the reasons drinking water is very expensive in different parts of the world like Germany than alcohol like beer. Having realised these,Prof.Christopher M. Aderemi Ademoroti, of the Dept of Chemistry,University of Benin,Benin City, recently developed a new technique for the desalination (removal of salt) from Sea Water.
The astute Don with over 35 years of scientific research has previously designed Fluidized bed technique for solving water problems in arid areas.In that, water can be treated for recycling, and clean water can be obtained from polluted water in less than 2 hours.
According to him, the technique he calls “Aquadem” technique brings fresh and good water to door step of people living in Coastal and Island areas. By this method the salt content in sea water is completely removed to meet the standard of the World Health Organisation WHO. Experts have lauded the research and commented that it is first of its kind in this part of our world. It is indeed a face-lift to people living in Island and Coastal regions of the world where their primary source of drinking water is usually sea water.
About the ground breaking research, Ademoroti, had this to say;”there are two methods in the world today for removing salts from sea water. These are “Reverse Osmosis”, and “Dialysis”, These methods are extremely expensive that no government wants to fund them. Secondly, the quantity of water produced by these methods is not large enough for commercial purposes.However, with my new technique, much fund will be conserved, and large quantity of water can be produced for commercial purposes”, the distinguished don said.
He further commented on his technique:”during the process of dessalination, i used different materials obtained locally in Nigeria for experimentation. Their compositions were studied and known, and then used for the process. The process involves loading the materials in vats and the sea water is allowed to pass through. After the processes, the resultant water obtained was tested for various water characteristics and the values obtained compared favourably with WHO standards for drinking water. For example, the water was found to be colourless ,odourless, tasteless (totally free from salt), boils at 100oC and freezes at 0oc.
The research which took the expert many years to complete will be useful to people living on Islands and coastals regions of the world where their primary source of drinking water is usually salt water. The quintesential researcher has almost 100 journal articles published mostly internationally. He is a keen researcher, and an inventor. These attributes have earned him international recognitions. The International Biographical Centre, Cambridge, U.K, has listed him among the “WHO’s WHO of Intellectuals’, Men and Women of Distinction’ and ‘Leaders in Achievement’. The American Biographical Institute/Marquis WHO’s WHO have listed him among WHO’s WHO in Science and Engineering’ and ‘WHO’s WHO in the century’.He has been nominated for publication in the Legacy International magazine Lagos,as one of the 50 greatest scientists Nigeria has ever had.
Prof Ademoroti is not only a scientist, but also a seasoned theologican and an articulate preacher. He has flare for literary work. Apart from ‘Biblical Economics’ the title of one of his books, other books he has written include: ‘In His Service’, ‘Jesus Christ the king and His kingdom’, ‘Environmental Chemistry & Toxicology’, ‘Chemical Thermodynamics’, and ‘Standard Methods for Water & Effluent Analysis’. Ademoroti has many awards to his credit, which include: the distinguished leadership in National Development Gold Award (2007); The Development in Nigeria Higher Education Merit Award; among others. Above all, Prof. Christopher Ademoroti, is an ordained priest of the Methodist Church Nigeria. He ministers in All Saints Chapel, University of Benin, where he is one of the chapel priests.
