Abstract
California is facing a water crisis due to the lack of rain in the recent years. If California continues without rain, California will eventually run out of fresh water. Residents are asked to reduce their intake by a 20% decrease and the cost to consume water is increasing rapidly. At this point, California cannot afford to waste any water. Because of the high demands of water, Agricultural businesses have increased their prices and pay a lot more for extensive water cleaning equipment. In order to recycle water, it is questioned if algae can replace water-cleaning equipment. In order to work toward this goal, the experiment observed the growth of Dunaliella primolecta, Scenedesmus dimorphus, and Chlorella vulgaris over the course of a couple weeks in various NPK levels. When the optimal NPK media was found, Orchid Grow More was used along with the wastewater in order to help the algae grow faster. In order to determine if algae can really clean out the organic material in wastewater, the COD (chemical oxygen demand) was observed before and after inoculation. Decreased levels of COD would confirm that algae are in fact able to filter and clean out wastewater.
