Personal water purification system without the need for electrical energy

In this research, a portable, personal water purification system without the need for electrical energywas designed and constructed by combining membrane processes and modified surface adsorption.The performance of the designed system was evaluated using various surface and groundwatersamples. The results show that the amount of Escherichia coli (E. coli) in the water purified bypolypropylene hollow fiber membranes with pore sizes of ۳۰ to ۲۰۰ nanometers is zero. Moreover,the physical properties of the water, such as pH and total hardness are compatible with national andWorld Health Organization (WHO) standards after passing through an adsorbent bed of ion-exchangeresins regenerated with NaCl and NH۴HCO۳.
