UV Hydrogen peroxide exposed to UV light produces hydroxyl radicals that result in advanced oxidation to destroy UV-resistant contaminants such as 1,4-dioxane.

DecarbThe combination of decarbonation and lime stabilization raises the pH and adds hardness and alkalinity to make the purified recycled water less corrosive and more stable.

California has been in a drought since 2011 and has been placed in a state of emergency by Governor Brown in order to alleviate the huge demand of fresh water by implementing mandatory water saving strategies. Literature review was conducted to learn the several processes that California municipal water districts use in creating potable water from historically ignored sources such as grey water and seawater. Technologies implemented by said districts such as microfiltration, reverse osmosis and ultra-violet irradiation were studied. The objective of this research project is to emulate these industrial scale water treatments strategies in a pilot scale system in order to gather water treatment data. Grey water will be treated via a three-step process using micro-filtration, reverse osmosis, and an ultra-violet light stage for final disinfection to produce potable water. New ethical standards along with popular support for sustainability practices have created the need to find new sources of renewable and alternative energy. This has lead this investigation into the use of photovoltaic (PV) panels as a power source to create a solar-assisted and reliable water purification system. The purpose of creating a solar-assisted energy system is to apply such technologies in areas where both potable water is scarce and sunlight is readily harvested. PV technology allows communities with limited or no access to traditional energy sources to power these systems, while also having a zero carbon footprint. Overall, this study hopes to illustrate the viability of self-powered and mobile water treatment applications.

Objective This research project is to emulate these industrial scale water treatment strategies in a pilot scale system in order to gather water treatment data. We will be implementing a three-step process which will include: micro-filtration, reverse osmosis, and an ultra-violet light stage for final disinfection purposes. Talk about the influent and effluent(s) of our system.

• We constructed a water purification system that focuses on grey water reuse. Specifically, our goal was to convert grey water influent into direct potable effluent. We are ready to filter grey water through the machine and future tests and analysis will continue throughout the 2016-2017 academic year.

This system provides an alternative source of potable water for drought-stricken regions. Since grey water influent poses acute health risks, advanced treatment is applied to ensure the elimination on community health concerns.

Phase 1: Primary Treatment• Wastewater reaches the sewage treatment plant

• Solids are removed, then tiny dirt-loving micro-organisms,• They eat particles that are too small to see or too light to settle.• Once they get full and heavy, they fall to the bottom and cleaner water rises to the surface.

• Tertiary treatment• The water goes through a filtration process

• Water passes slowly through layers of coal, sand and gravel much as natural underground seepage occurring in aquifers.

Phase 2: Microfiltration Process• Water is pressurized through pipes containing straw-like fibers with pores that are 5,000 times smaller than a

pinhole. Phase 3: Reverse Osmosis• Water is pressurized at about 200 pounds per square inch through tightly wound layers of membranes with pores

that are 5 million times smaller than a pinhole!
