Abstract
This research was conducted to treat peat water using oxidation and physical filtration system. Initially, the characterization of peat water was determined by three parameters, including iron (Fe), turbidity, and color. These three parameters exhibited values that exceeded the water standard limit. This study used two samples consisting of high and low iron content. Both samples were treated using NaClO for the oxidation-catalytic process and Manganese sand for the filter. The trial time is 67 minutes by calculating the value of each parameter every 10 minutes. The result shows different performance in the sample with low iron and high iron. In the sample with low iron (0.32 mg/l), the efficiency of reducing iron is 65.62%, the efficiency of reducing turbidity is 78.95% and the efficiency of reducing color is 78.77%. The results obtained showed differences in samples with high iron (6.75 mg / l). Iron reduction efficiency is 29.17%, turbidity reduction efficiency is 69.05% and color reduction efficiency is 61.32%.
Highlights
Water is essential and fundamental to all living forms and is spread over 70.9% of the earth’s surface (Syafalni, Abustan, Brahmana, Zakaria, & Abdullah, 2013)
It is essential to ensure the availability of local sources of water supply and even develops new potential sources of water such as from peat swamp forests to overcome future water shortages. (Syafalni, Abustan, Brahmana, Zakaria, & Abdullah, 2013)
The scarcity of clean water sources caused peat water has been used as an alternative (Apriani, Masduqi, & Hadi, 2016), potential of water available in nature (Ardiansyah, Bahri, Saryono, & Wawan, 2016) and an important natural resource comprising highly modified plant remains that accumulate in certain wet habitats. (McBrierty, Wardell, Keely, O'Neill, & Prasad, 1996)
Summary
Water is essential and fundamental to all living forms and is spread over 70.9% of the earth’s surface (Syafalni, Abustan, Brahmana, Zakaria, & Abdullah, 2013). Peat water has a high degree of acidity (pH between 35), low suspended particle content, and high brownishred color intensity with high organic matter content.(Suherman & Sumawijaya, 2013), acidic (low pH), brown color and contains organic (Rusdianasari, Bow, & Dewi, 2019) (Eri & Hadi, Unknown) (Irvine, Vermette, & Mustafa, 2013) This is caused the water source in the area is peat water wich based water quality parameter does not meet the requirements of the freshwater quality to WHO standard (Zein, et al, 2016) and peat water in general does not meet the clean water quality standards that are standardized by the Indonesian Ministry of Health through PERMENKES No.416/ MENKES /PER/IX/1990. Various efforts and techniques need to be continued to find the most effective and efficient ways to manage clean water
