I NTRODUCTION TO EWM April 2019 Extracting Minerals From Water

I NTRODUCTION TO EWM n Enviro Water Minerals Company (EWM) has created a revolutionary desalination solution that extracts the dissolved solids contained in a variety of salty water sources for beneficial use n EWM extracts and sells the minerals found in salty waters, thereby reducing the cost to desalinate water – Full resource recovery (no residual waste water / disposal issues) – Coupling of revenue from mineral sales and sale of potable water makes business model feasible n Intellectual Property – portfolio of 12 patents / patents pending 2
