520			_aTrickling filter is one of the cheapest and easiest secondary water treatment alternatives that can be adopted and used. It is a packed bed of media covered with slime over which wastewater is passed so that it ?trickles? downward as a thin laminar film. Oxygen and organic substrates diffuse through the liquid film into the slime film where biological oxidation and synthesis occur. End products and sludge appear in the filter effluent. The researchers decided to create a prototype of a trickling filter to present its efficiency and all its advantages. This is to aid the current water shortage problem and preserve water in the world or more specifically in Cebu City. The researchers have researched about all the aspects to be considered about a trickling filter and gathered the necessary knowledge on how to create the prototype and utilize the cheapest materials available for the formation of the trickling filter. After having the prototype formed and created, the researchers started right away with the process by letting water flow through the filter. The water used as primary source was untreated water coming from a river near B. Rodriguez Street. The researchers strained the water for primary treatment before letting it pass through the filter. The necessary way that should be done is not to have a continuous cycle of water, but due to the lack of source of water, the researchers decided to let the water circulate throughout the filter. This was made possible by using a pump connected to a hose that would transmit the water back to the primary source. After a month from the filtration process has started or after one month of continuous flow of water through the filter, the researchers took their first sample of output water from the filter and placed it in a separate container. Another one month of continuous flow of water has passed and the researchers then took their second sample. The second sample was then placed in another container and prepared for water testing together with the first sample. The researchers then brought both of the samples to MCWD Talamban Plant for water testing. As soon as the results of the water test were available, the researchers studied the results. With the given data and results, the researchers have concluded that the trickling filter is successful. Even with insufficient time, the researchers have observed a significant difference with the two samples of water that has passed through the filter. This indicates that the filter could have produced a better result if only there was enough time of the filtration process. But still the researchers found out the efficiency of this alternative treatment and how it makes a big difference in terms of costs and expenses compared to other secondary water treatment alternatives. The researchers recommend that much time must be given in the flow of water through the filter in order to allow all the necessary microorganisms to be developed. These microorganisms are the most important factor for the efficiency of the filter for they are the ones responsible for the treatment. In connection to this, much attention must be given throughout the process so that there will be no disturbances that would happen in the sample obtained. The different water quality parameters? permissible value will be achieved by the sample if only there were no disturbance factors allowed during the process. The researchers also recommend providing of another container that would be responsible for the settlement of sludge so that the sludge will be separated from the water before going through the output container.
