Design of a 50 Kld Mobile Water Treatment Plant for Brackish and Stormwater.

This project proposes the production of 50 KLD of drinkable water from brackish and stormwater in a mobile water treatment plant. This project is aim for providing drinkable water to municipalities that have been affected by natural disasters and lack access to drinkable water. It was developed a preliminary design and study of feasibility by selecting the appropriate technology, designing a process, and developing an economic analysis. First, the data for designing the system was obtained from different locations around Texas during Hurricane Harvey. Second, for treating both brackish and stormwater the process was defined to have a sedimentation tank, activated carbon filters, antiscalants, reverse osmosis membranes, and a disinfection tank. Third, an energy balance established the use of a submersible pump and a multistage centrifugal pump, also the possibility of series and parallel pumps was considered. It was observed that the project is feasible from a chemical and spatial point of view. Also, it has an ROI of 53% and PBP of 1.7 years which makes it economically viable. Moreover, it was demonstrated that the system could achieve drinkable water if seawater is injected. The implementation of this project would lead to access to safe drinkable water at affordable prices and easily.
