The corrosion inhibition efficiency of the vasaka leaf extract for protecting mild steel in potable water (neutral aqueous medium) was studied by weight loss, Open circuit potential monitoring and potentiometric polarization methods. The inhibition test was performed in potable water rather than deionized water because inhibitors are normally applied in neutral and industrial waters. The extrac...

The Johns Hopkins Hospital in 1999 began to evaluate the safety and efficacy of chlorine dioxide for Legionella control in a potable water system in an acute care hospital environment. The evaluation includes chlorine dioxide, its by-products and their impact on Legionella and pathogenic bacteria, biofilm, medical and laboratory filtration systems, corrosion rates and the environment. The appli...

The WHO suggests that humans require an absolute minimum of 7.5 L of water per day, while a minimum of about 20 L of water per person per day is recommended to ensure adequate hygienic standards. With a population of 7.5 billion, this works out to 150 billion litres of safe freshwater daily, globally. Much more than this is generally consumed in developed nations, while less than adequate amoun...

Rainwater is extremely important for the arid regions of Tunisia a better valorization this water, indigenous these decided to build earthen cisterns (Majel and Fesquia) collect rain satisfy their needs have sufficient long-term water reserve in case prolonged drought. Despite difficulties faced access mountainous regions, survey was conducted concerning all characteristics uses. 120 samples be...

Since less than 1 percent of world waters are potable, minimizing water consumption is a significant issue. The aim of this study is to present a suitable algorithm for optimization of water consumption in water pinch analysis. In this regard, the results of computer algorithm are verified by the results of previous studies. As a case study, dissolved solid pollutants are taken into considerati...
