Water scarcity is a problem the world is facing nowadays. Although the amount of water in the world is in vast supply, the portion of water which is available for human consumption is in limited supply. Water filtration is a method which best remedies this catastrophe. There are numerous water filtration methods but they are either too expensive or they use inorganic substances which can be dangerous to our health. Also, there has been very little development on water filtration methods that best fits situations where in natural calamities are occurring. The researchers aim to answer these problems by developing a prototype of a water filtration design that makes use of an organomineral based substance that contains zeolite Zeolite, which has the capability to flocculate bacteria and other defects that disallows water for human consumption. It is used as an adsorbent for metallic contaminants in water and subsequently removed from the medium by a simple magnetic process. This research study also aims to test the effectivity of an organomineral-based water filter in the purification of water through several water quality parameters. The study included the optimum ratio of fine sand and organominerals and the Sewage water used was from a sewer canal in J.C. Aquino Avenue Butuan City. This was collected to test the filtration capabilities of the organomineral based substance. Four setups with 5 trials were made and water quality parameters such as pH, Total Suspended Solids and Dissolved Oxygen were done to see its effects. Results showed that the organomineral filters proved to be more efficient in treating wastewater interms of their pH, dissolved oxygen and Total Suspended Solids, than that of the sand filter without the presence of zeolite. It showed that there is a significant difference between variables and as organomineral concentration increases, Total Suspended Solids decreases. It also showed that there is a significant difference in Dissolved oxygen level between the sand filters with organominerals. As the amount of organominerals increases, Dissolved oxygen also increases. There seems to be no significant difference in pH if the amount of organominerals increases but there is a significant change when organominerals are added to the sand filter. The optimum setup of the organomineral substance is setup D with an organomineral depth of 37.5cm. The water filter remains effective until 35 liters of wastewater is poured into the filter. Beyond this point, the filter no longer goes within the range of the C classification of water.
