“…Sources of color in water encompass natural metal ions such as iron and manganese, humic and fulvic acids, lignin, algae, peaty substances and sulphuric bacteria that can be removed via conventional coagulation, flocculation and filtration processes [12]. Based on The TDS parameter indicates the presence of organic or inorganic substances in the water where it may increase because of the addition of chemicals, or an excess of hydrolysed PAC products, both in dissolved and partially dissolved forms [4,13]. Random addition of coagulant PAC dose without conducting jar test led to unfavorable data results due to over or underdosage of coagulant, urging sufficient daily monitoring by the operation [11].…”

Clean water is crucial to ensuring the well-being of people. The Package Timah Tasoh Water Treatment Plant (WTP) is designed to support the existing conventional plant in coping with the growing demand for clean water. The package plant used the Compact Water Treatment System, classified as a Category B in the Suruhanjaya Perkhidmatan Air Negara (SPAN) guidelines; thus, this performance monitoring research was conducted prior to product registration. The plant consists of aeration, flocculation, clarification, and filtration processes. The performance of this package plant was monitored through comparative and efficiency analysis of removal parameters and carried out over a period of six (6) months. Twelve (12) water quality parameters were selected, including turbidity, pH, total dissolved solids (TDS), colour, ammonia, residual chlorine, aluminium, iron (Fe), manganese (Mn), fluoride, standard total coliform, and E. coli with sampling water of RW, SW, FW, and TW, which was then assessed alongside the drinking water quality standards set by Ministry of Health (MOH). As a result, eight key parameters such as pH, turbidity, colour, TDS, iron, aluminium, manganese, and ammonia were meeting the MOH drinking water quality standards in over 94 % of cases. The remaining parameters are chlorine residual, fluoride, E. coli and standard total coliform were in non-compliance due to the inoperability of disinfection and fluoridisation processes. Most of the significant parameters deduced a better performance in terms of removal efficiency (> 60 %) consistently, except for TDS, throughout the monitoring activity.

“…There are more than 700 manufactures comprised from the Thai natural rubber (NR)‐based industries to produce many types of latex products, for example, aircraft and automobile tires (mostly) along with gloves, condoms, foam rubber as pillow and mattress, elastic band, and clothing, etc. Concentrated latex is one of the important products with an annual production of ~4.47 million tons (Mt) in Thailand as of 2016 with a positive incremental trend 1,2 . Since 2003, Thailand (as the world's largest NR producer and exporter) has a share of about 35–40% of NR latex products all over the world 3 .…”

“… 11,12 Lower pollution, fewer dust levels, lower transportation and storage costs, lower combustion surplus, higher combustion efficiency, and higher energy density, with these kinds of advantages of biomass pellet fuels, can be used in combustion, which is better than the traditional biomass fuel (re)sources 13 . As the amount of latex CLS produced continues to grow, 2 and therefore, it would be a great environmentally, economic, and social auspicious, if CLS could be used further extensively as biomass pellet fuel to generate energy and its sustainable management as well. Hence, considering some issues, the present research is significant and potential to build up an advanced sustainable green and safe environment.…”

Natural rubber-based industries in Southern Thailand are generating concentrated latex sewage sludge (CLS), which is commonly managed by landfilling practice that is causing serious environmental hazards. The purpose of this study was to develop a method to produce pellets using CLS and para-wood sawdust as a potential biomass source for energy generation. The process started with dewatering the CLS through a decanter centrifuge. Then a flat die pellet mill was applied for copelletization. Finally, the pellets were investigated to evaluate the higher heating value and toxic heavy metals (Cu, Zn, Cr, As, Cd, and Pb) using proximate-ultimate analysis, fourier transform infrared analysis, scanning electron microscopy, calorific value, thermogravimetric analysis, atomic absorption spectrometer, and inductively coupled plasma optical emission spectroscopy. The results showed that the addition of the parawood sawdust resulted in higher heating value and lower ash content of 3,620 ± 12 kcal/kg and 4.93 ± 0.98%, respectively. Besides, it has increased the carbon content of the pellet from 28.23 to 46.26% highest among all the samples. Furthermore, the method developed in this study is not only environmentally friendly but also economically sound than the earlier management of CLS.
