“…As indicated in the decreased UV absorbance spectra of the tropical peat water in Figure 2, the alum coagulation and AC adsorption have a considerable impact on the removal of DOM from the sample. Since the alum coagulation removed hydrophobic DOM [34,35,36] such as humic acid [31] that dominates the tropical peat water, the UV absorbance in all wavelength regions has decreased significantly. Additionally, following the AC adsorption procedure, UV absorbance was once more lowered.…”

The dissolved organic matter (DOM) protonated fractions of various hydrophobicities were correlated with the tropical peat waters' UV–Vis spectral slopes. This study was conducted to determine how microbubble pre‐ozonation affects UV–Vis spectral slopes in tropical peat water treatment processes This study was conducted to determine how microbubble pre‐ozonation affects UV–Vis spectral slopes in tropical peat water treatment processes. Microbubble pre‐ozonation was carried out at pH 7 followed by alum coagulation and activated carbon (AC) adsorption. The results showed that the log‐transformed UV–Vis absorption of processed peat water had four spectral slopes in the range of 220 to 420 nm. The degradation of the transphilic (TPH) DOM fraction had a strong negative correlation with the S220‐240 and S241‐272 values (R2 > 0.85). Similarly, the hydrophilic‐charged (HPIC) and hydrophilic‐neutral (HPIN) fractions had a strong negative correlation with the S220‐240 and S241‐272 values (R2 > 0.84 and R2 > 0.70). Meanwhile, the S273‐350 S>350 values had a low and negligible correlation with all analyzed DOM fractions (R2 < 0.30). The lower wavelength spectral slopes ratio (S220‐240/S241‐272) was moderately correlated with the DOM fraction, while the correlation with higher wavelength values was negligible. Based on these findings, the UV–Vis spectral slopes ratio at lower wavelengths appears to be useful information for developing a surrogate parameter of DOM fractions in peat water treatment processes.

“…However, due to the presence of natural organic matter in peat water, the conventional filtration process using a sand filter has little impact. This is because sand filtration is typically used to filter flocs formed during the coagulation process that are not entirely deposited by gravity [Khayan et al, 2022]. Therefore, a more intricate filtration process is required to eliminate the presence of hydrophobic natural organic matter such as humic acids from peat water.…”

Peatlands have ecological importance, human activities and climate change have created various environmental challenges for peatlands. One of the problems with peatlands is the degression in the quality of peat water, which has a negative impact on ecology and human health as well as the welfare of local communities who depend on peat water as a source of clean water. The problem of peat water processing lies in the need for large capacity, ease of maintenance, and water quality that meets standard criteria. The aim of this research is to evaluate the combination of filtration, absorption, and double flow ultrafiltration techniques, and compare them with single flow ultrafiltration techniques for treating peat water in the South Kalimantan region of Indonesia by looking at the amount of production and quality of water treatment results. This research proposes dual flow ultrafiltration as a solution for treating peat water on a large scale up to 2 times and results in better water quality than single flow ultrafiltration treatment. This is indicated by the percentage difference in TDS reduction of 19.5%, color of 23.1%, nitrite of 37.8%, and manganese of 69%. However, the dual flow ultrafiltration method still has a higher turbidity of around 60.65% and nitrate of about 15%. However, these water treatment results are still standardized by the Indonesia Minister of Health PERMENKES No.492/MENKES/PER/IV/2010.
