ABSTRACT
Wastewater treatment is the process which changes the physical, chemical, or biological composition of wastewater and reduces its potential for polluting waters. Treating the wastewater helps make the rivers and streams safer for people, fish, plants, and other living things. Using chemicals is one way of treating wastewater. This study aims to develop an alternative way of treating wastewater that would not cost much. It is hypothesized that there is no significant difference in the pH, total dissolved solids, and temperature of the waste water treated or untreated with Kappaphycus alvarezii. Fifty grams of K. alvarezii was placed in every set-up. Each set-up would contain four samples of domestic wastewater, two would be treated and the other two would be untreated. The other set-up was used for the industrial wastewater with two treated and two untreated samples. The parameter values are then gathered after three months. It is then analyzed if it has passed the standards set by the Department of Science and Technology. For this study, the marine seaweed Kappaphycus alvarezii is used tor the conduction of the experiment, and it can also be other types of seaweeds, however, this species was used because it is commonly found here in the Philippines.
