An Investigation of a Conventional Water Treatment Plant in Reducing Dissolved Organic Matter and Trihalomethane Formation Potential from a Tropical River Water Source

Abstract

 Observed changes in DOM characteristics and THMFP occurrence in polluted tropical raw water and along conventional drinking water treatment processes over the dry and rainy seasons.  Presence of protein compounds indicating raw water pollution.  Influences of the ratio of tryptophan to humic compounds on the performance of drinking water treatment over two different seasons.  Relevant parameters that can be used in monitoring the quality of both raw and treated water.

Characterization of Fluorescent Dissolved Organic Matter in an Affected Pollution Raw Water Source using an Excitation-Emission Matrix and PARAFAC

“…As seen in Figure 1, the water intake is located in natural forestry area (Djuanda National Park) with an area that occupies almost 20% of the catchment of the upper stream area (6,933.30 Ha). The catchment of the upstream area is dominated by anthropogenic activities (81% of the total catchment area) such as agriculture, plantations, cattle manure, tourism, and residential (Sururi et al, 2020). According to the Central Bureau of Statistics, the largest livestock in this area is located along this watershed (BPS KBB, 2019a), accounted by approximately 21,043 cows, 17,918 sheeps, and 526 horses (BPS KBB, 2019b).…”

“…The authorized drinking water company in Bandung City has reported difficulties in treating the raw water during dry season (Sururi et al, 2020). This was indicated by not optimum formation of flock, and more frequent cleaning of secondary treatment units and backwash of rapid sand filter during the dry season than the rainy season.…”

“…Sebagai konsekuensi dari turunnya kualitas badan air yaitu menyulitkan proses pengolahan air minum (Sururi et al, 2020).…”

Evaluation of Regional Domestic Waste Water Treatment Plant Performance in Cimahi City

“…Sanitation problems related to the domestic wastewater management system are still among the main environmental problems in Indonesia's big cities. Domestic wastewater that is not treated correctly can cause pollution to the water environment (Soemirat, 2011), both groundwater and surface water which are the primary sources of raw drinking water (Sururi, Notodarmojo, & Roosmini, 2019;Sururi et al ., 2020). Poor ground and surface water quality due to domestic wastewater pollution is the leading cause of disease through water agents such as diarrhea, cholera, and typhoid (Jin et al, 2018;Nienie et al, 2018).…”

“…Water-borne diseases in Indonesia are estimated to be the cause of death for 31% of children under five years of age (Ministry of Health, 2020) and economic losses that reach 2.3% of the annual figure for the national gross domestic product (World Bank, 2013). Apart from hurting human health and the economy, insufficient quality raw water will also complicate the drinking water processing process (Sururi et al,.2019;Sururi et al, 2020). Thus, an excellent domestic wastewater treatment system will be able to protect public health from water-borne diseases.…”
