Pengaruh Ketebalan Media Pada Pengolahan Air Gambut Dengan Media Filter Karbon Aktif, Pasir Kuarsa Dan Batu Apung
Peat water is a type that falls short of health standards, characterized by a reddish-brown color, high organic content, and low pH. It is prevalent in Riau Province, making it a vital water source for the community. An alternative for treating peat water is the biosand filter. This research aims to analyze the influence of varying media thickness, including gravel, pumice, quartz sand, and activated carbon, in biosand filters on peat water's pH increase, color reduction, and organic substance decrease. The water source is from a well on Soekarno-Hatta Street, Pekanbaru, Riau, with an average flow rate of 0.25 m3/m2/hour and a fixed thickness of 10 cm for activated carbon. Five variations in pumice and quartz sand thickness are employed: 40 and 20 for the first, 35 and 25 for the second, 30 and 30 for the third, 25 and 35 for the fourth, and 20 and 40 for the fifth. Research results indicate that the fifth variation, with gravel 20 cm, pumice 20 cm, quartz sand 40 cm, and activated carbon 10 cm, provides the highest efficiency in increasing pH by 34.95%, reducing color by 92.64%, and decreasing organic content by 92.00%. These outcomes meet clean water standards per Minister of Health Regulation number 32 of 2017, except for the organic content parameter.
