Trubus.id – Yogyakarta State University (UNY) students who are doing a Real Work Lecture (KKN) in Andong Village, Need District, Purworejo Regency, build a simple water purifier. The instrument is made with paralon and natural materials readily available in the surrounding environment.
According to Rodul Khanan, a student of KKN UNY, in water treatment, filtration or filtration is a water treatment technique that is applied with the help of filter media such as sand such as silica, anthracite, chemical or mineral compounds like lime, zeoliteactivated carbon, resin, ion exchangemembranes, biofilters or other filtration techniques.
Therefore, there is a need to make portable water treatment equipment that is affordable and easy to use and that can be moved to other places so that it can help the community get decent quality clean water.
Meanwhile, Estu Panduaji Wijaya, another UNY KKN student, explained that there are different materials used to make water purifiers. These include paralon, silica sand, spons acquadina, mangano zeolitemetallic gauze and activated carbon.
“Mangana Zeolite it acts as a catalyst and at the same time the iron and manganese present in the water are oxidized to form ferric oxide and manganese dioxide which are insoluble in water, ”Estu explained as quoted from the page. Yogyakarta State University.
The function of silica sand is to remove the mud or soil and sediment content in drinking or ground water or PDAM water or mountain water in the water treatment industry.
Meanwhile, activated carbon works to remove micro-pollutants such as organics, odors, as well as removing iron (Fe) content, by removing a small amount of manganese (Mn) and the yellow color in groundwater or other sources of d ‘water.
In the activated carbon filtering process, an absorption process occurs, i.e. the process of absorbing substances that will be removed from the surface of the activated carbon. If the entire surface of the activated carbon is saturated or can no longer absorb, it must be replaced with new activated carbon.
Furthermore, the use of spongy material serves to absorb water deposits that make the water color cloudy.
Assembly process
The assembly process on the main paralon consists of silica sand, spons acquadina, mangano zeolite, and again silica sand. In the second, smaller paralon, it is filled with activated carbon and spons acquadina. The water is poured into the main paralon, after being filtered it will enter the second paralon and distilled water can be used.
According to Winda Pramudya Wati, another member of UNY KKN, the water resulting from the filtration process has no taste, smell and color, so it is appropriate for the community to use it for bathing and washing.
“The tools and materials needed to make a water filtration device are easy to obtain, easy to manufacture, inexpensive and easy to maintain,” said Winda.
