Article Synopsis
- * Higher ozonation pH levels improved NP degradation but altered DBP formation, leading to reduced cytotoxicity at acidic and neutral pH, while increasing it at alkaline conditions.
- * The researchers concluded that pH adjustments are not necessary to lower DBPs during the ozonation of NP in bromide-rich water and suggest further exploration of natural organic matter's role in DBP production.
This review discusses disinfection by-products' (DBPs) potential precursors, formation, and toxicity, alongside available research on the treatment of DBPs in Southeast Asian countries' water sources. Although natural organic matter (NOM) in the form of humic and fulvic acids is the major precursor of DBPs formation, the presence of anthropogenic organic matter (AOM) also plays essential roles during disinfection using chlorine. NOM has been observed in water sources in Southeast Asian countries, with a relatively high concentration in peat-influenced water sources and a relatively low concentration in non-peat-influenced water sources.

Article Synopsis
- Indonesia has a population of 270 million, leading to significant domestic wastewater generation, with grey water quantities being 1 to 4 times higher than black water.
- Untreated grey water poses a major pollution threat, being 3 to 6 times more prevalent than untreated black water, with concerning levels of contaminants like suspended solids and nitrogen.
- Improving wastewater treatment is crucial, as current on-site black water systems often lack quality control; implementing incentive or penalty schemes could enhance treatment quality at various community levels.
Combination of electrokinetic soil flushing and bioremediation (EKSF-Bio) technology has attracted many researchers attention in the last few decades. Electrokinetic is used to increase biodegradation rate of microorganisms in soil pores. Therefore, it is necessary to use solubilizing agents such as surfactants that can improve biodegradation process.
