Abstract:

Water quality monitoring is of great importance in managing drinking water lakes or reservoirs. However, developing such an effective monitoring system used in evaluating water quality is difficult, due to spatial and temporal variation in water quality that are usually hard to interpret. Principle component analysis (PCA) and canonical correlation analysis (CCA) techniques were used in this study to determine the principle water parameters, and explore the relationship between the physical and chemical water parameters, respectively in Macau Main Storage Reservoir (MSR) that is experiencing a

Abstract:

The textile industry is one of the largest environmental polluters in the world. Although waste management via anaerobic digestion (AD) is a sustainable strategy to transform waste into clean energy and water recovery, the efficiency of the AD process is reduced by the presence of recalcitrant materials, chemicals, and toxic contents. This study aims to investigate the performance of several chemical, physical, and biological pretreatments applied to improve the biodegradability of textile waste. We performed a meta-analysis with 117 data extracted from 13 published articles that evaluated the

Abstract:

The paper concerns the problem of the occurrence of failures of the high-pressure ammonia water pipeline of the coke oven battery complex, which is affected by chemical and thermal factors as well as the operating pressure occurring during its use. Pipeline failures manifested themselves as leaks (leakage of the medium) due to cracks in the area of the pipeline thermal elongation compensators. The conducted tests included, among others: visual inspection, penetration tests, macroscopic and microscopic tests as well as chemical analysis of the material. The study includes microscopic photograph

Abstract:

Water is crucial for shaping the land and affecting the weather. It is essential for life, characterized by its physical features, ingredients, and life-related qualities. Due to fast industrial growth and the widespread use of fertilizers and pesticides in farming, water quality is taking a hit. People using polluted water face waterborne diseases. This study assesses the quality of water in the Kushalgarh block, Banswara Rajasthan.

Currently, as many as 45% of Indonesian people use well water to meet their daily needs. However, problems with the use of well water occur due to increasing population growth, resulting in increased water pollution. Waste generated by human activities can seep into the ground and contaminate well water. This research was conducted to determine the feasibility of well water as consumption water in the Kos area of Jember Regency. The method used in this research is a descriptive observation method. The study used seven samples of well water originating from the Kos area of Jember Regency an

Water quality is a condition that indicates the quality of water in a body of water, water sources and river basins. Water quality requires testing and analysis by considering its physical conditions, chemical content, and biology. Aik Nyet natural tourist attraction is one of the famous water sources in the Lombok area, West Nusa Tenggara. Bathing and swimming activities in this area can potentially cause pollution of water quality, but until now there has been no information regarding the quality of water in this natural tourist attraction.
