Natural Aqua Purifier: A Novel and Sustainable Water Purification Approach Utilizing Natural Coagulants for Easy Implementation in Rural Regions

Overview

Access to clean water is one of our most basic human needs. In fact, unsafe water sources are responsible for over 1 million deaths annually. UN Sustainable Development Goal 6.1 targets “universal and equitable access to safe, affordable drinking water for all” by 2030. Current water purification methods for rural areas have hazardous effects on human health, are expensive, and are not readily available. As a result, it was hypothesized that a combination of natural coagulants would purify water effectively. This study investigated the results of combining the natural coagulants moringa seed powder(M), neem leaf powder(N), and peanut husk powder(P) to purify raw water with heavy metal contamination. Water purification tests were conducted at home using minimal equipment to simulate the environment in rural regions. Furthermore, jar tests were performed in the lab to validate the accuracy of the results. The solution used the processes of coagulation, flocculation and sedimentation to purify the water. The prote ins in the natural coagulants contain positive charges which neutralize the colloids' negative charges, creating “flocs” that sink to the bottom. Filtration was used to remove the flocs. Experimental findings proved the hypothesis, M+P successfully reduced heavy metal concentrations: lead concentration by 94.5%, zinc by 79.4%, copper by 19.8%, and manganese by 52.4%. This research paves the way for providing clean water to the 2.2 billion globally who lack access to it by developing a novel, sustainable, and inexpensive water purification mixture for rural regions. The Emotional Resonance of Music: Exploring the Interplay of Frequency, Empathy, and Therapeutic Effects Aditya Tyagi Chaparral High School, Scottsdale, AZ Music is often referred to as the "universal language" because it has the power to connect people from diverse backgrounds, identities, and cultures. It transcends barriers, enabling individuals to appreciate and understand each other through shared musica l experiences. As British ethnomusicologist John Blacking defines it, music is "humanly organized sound," suggesting that its definition can be personalized. The connection between music and people lies in its ability to evoke emotions. Emotions, considere d as "energy in motion," are complex reactions involving experimental, behavioral, and psychological components (UWA Psychology and Counseling News, 2019). Understanding how thoughts and emotions interplay is crucial before exploring how music influences the brain, as emotions relate to energy and frequencies. Humans can be viewed as electromagnetic beings because our bodies continuously emit light, energy, or frequencies that convey specific messages or intentions. As discussed in Becoming Supernatural, "When we think a thought, those networks of neurons that fire in our brain create electrical charges. When those thoughts also cause a chemical reaction that results in a feeling or an emotion, those feelings generate magnetic energy. This energy merges with the electrical charges from thoughts to produce an electromagnetic field reflecting your state of being." This means that our feelings create magnetic fields that attract similar frequencies. For example, listening to sad music can have surprising effects. Research by Kawakami and colleagues (2013) found that listening to sad music often increases positive emotions such as tranquility and serenity while reducing negative emotions like anxiety and anger.
