Chapter 1 1. Introduction Through the years, the wastewater treatment technology has been continually improved and researched to provide efficient treatment methods. The trend today is designing methods and equipment for easy access to common people. Such includes the filtration system designed by Wickramaratna et al. (2009) in Cambodia and the inspiration of this research. Accessible, low cost, and user-friendly equipment is what the researchers aim for designing the filtration equipment. The use of different filter media in designing the filtration equipment aims to improve the quality of water produced after the process. Locally available materials are utilized like bamboo, sand, charcoal, clay, and organic materials like Malunggay seeds and cow manure. Bamboo is widely available here in the Philippines. Sand, charcoal, and clay are also accessible. In this research, malunggay ( M. oleifera ) seeds will be mixed with clay to make a porous membrane. According to studies, malunggay seeds are effective coagulants. It is also widely available throughout the archipelago.

    As a current student on this bumpy collegiate pathway, I stumbled upon Course Hero, where I can find study resources for nearly all my courses, get online help from tutors 24/7, and even share my old projects, papers, and lecture notes with other students.

    I cannot even describe how much Course Hero helped me this summer. It’s truly become something I can always rely on and help me. In the end, I was not only able to survive summer classes, but I was able to thrive thanks to Course Hero.

    The ability to access any university’s resources through Course Hero proved invaluable in my case. I was behind on Tulane coursework and actually used UCLA’s materials to help me move forward and get everything together on time.
