Lab conducts low cost water purification test


The Water Testing and Surveillance Laboratory of Liaquat University of Medical and Health Sciences (LUMHS) Jamshoro performed a low cost efficient water purification test of natural sunlight treated water.
A University spokesman informed here on Thursday that the idea encompassed a scientific principle based on bacterial efficiency of ultra violet rays contained in the sunlight adequately available in Pakistan round the year. Vice Chancellor Prof Dr Mashoor Alam Shah had directed to carry out water test in this regard, the spokesman informed. The water samples having evidence of microorganisms were exposed to sunlight in plastic bottles for six hours and 48 hours respectively via SODIS (Solar Water Disinfection) Method. No microorganism activity was seen when analysed by PMN and filtration techniques and having no health threat if consumed by human being. Untreated water from the same source showed a tangible level of microbial activity surely hazardous for human health if consumed.
The LUMHS spokesman said that water analysis confirmed the efficacy of Ultra Violet Rays which we have in abundance for clean water purification with merely no cost involved. It simply involves instruction and education of common masses how to use efficiently this cost effective method for enhancing safety of their drinking water, he said. The spokesman informed that the University has issued a disclaimer that such intervention does not confirm cent percent safety, but it surely enhances it. Interestingly, such cost effective method does not involve any special technology, he said and added that the process advised is more reliable in transparent water than the muddy or translucent water from any contaminated source.
The spokesman informed that Vice Chancellor Prof Dr Syed Mashoor Alam Shah has invited the observations, recommendations or any suggestion by subject matter specialists and research scholars of the subject so as to extend an authentic advice to the common masses in Pakistan for adopting this method of purifying drinking water.
The Vice Chancellor is committed to bring down the mortality and morbidity due to water borne diseases which is now around 80 percent of the enteric diseases with huge patient load on public and private sector hospitals, the spokesman said and added that only the import of anti- diarrhea medicines cost a lot of amount.
The University offers actual cost based water testing services to the provincial and district governments, non-government organisations, autonomous bodies, international collaborating agencies and even the individuals to contribute to the national efforts for drinking water safety.
