Different techniques of car washing are presented in this paper, along with issues of water use, water contamination and its purification. Nowadays, technological advancements in the car wash industry fall into specific categories such as, new washing technologies (touch-free and hybrid washing technology), advanced water recycling systems (based on biological water treatment), water desalinati...

This work suggests a solution for preventing/eliminating the predicted Sea Level Rise (SLR) by seawater desalination and storage through large number of plants distributed worldwide; it also comprises that desalinated can resolve global water scarcity complete coverage demand. level rise be prevented desalinating additional accumulated into oceans annually human consumption, while excess amount...

A pilot system was designed and constructed to evaluate reverse osmosis (RO) energy reduction that can be achieved using pressure-retarded osmosis (PRO). The RO-PRO experimental system is the first known system to utilize energy from a volume of water transferred from atmospheric pressure to elevated pressure across a semipermeable membrane to prepressurize RO feedwater. In other words, the sys...
