The Treatment of Water Using Activated Carbon Adsorption and Sand Filtration: Physical Characteristics Analysis for Clean Water Production
AI summary Read the abstract
Researchers in Indonesia tested a simple, low-cost filter made of sand and activated carbon (like the material in home water filters) to clean up polluted river water. The filter made the water noticeably cleaner—reducing cloudiness and dissolved pollutants while keeping a safe, stable pH—showing it could help supply safer water for things like farming, livestock, and recreation in areas without access to advanced treatment plants. This matters because contaminated river water is a major health risk in many developing regions, and affordable filtration methods like this one could offer a practical way to reduce exposure to pollutants and waterborne germs.
The Kalibaru River in Indonesia faces significant pollution challenges due to industrial and human activities, threatening ecosystem balance and water quality. To address this, a sand and carbon filter-based water filtration system is employed to improve water quality to grade 2 clean water standards.The method involves filtration using sand filters, carbon filters. Results show improved water quality with parametersThe decrease in turbidity from 6 NTU (March) to 5 NTU (June) indicates the filtration system's ability to remove suspended particles. Additionally, the decrease in electrical conductivity from 179.83 umhos (March) to 173.41 umhos (June) and TDS from 95.9 mg/L (March) to 92.7 mg/L (June) shows the system's ability to reduce dissolved ion concentrations.The stability of pH between March (7.58) and June (7.38) indicates that the filtration system does not affect the water's pH balance, remaining within the class 2 water quality standard (6-9). The relatively stable water temperature between March (27.5°C) and June (27°C) also shows that the filtration system does not significantly affect the water temperature with Indonesian Government Regulation No. 82 of 2001.The system effectively removes contaminants, reduces turbidity, and kills pathogenic bacteria, making the water suitable for recreation, freshwater aquaculture, livestock, agriculture, and other uses. Regular monitoring and maintenance are necessary to sustain water quality.Indonesia's river water quality has been declining due to industrial pollution, pesticide and fertilizer use, and plastic waste. To combat this, efforts are being made to improve wastewater management, promote sustainable agriculture practices, and enhance public awareness.

The Treatment of Water Using Activated Carbon Adsorption and Sand Filtration: Physical Characteristics Analysis for Clean Water Production
AI summary Read the abstract
Researchers tested a simple filtration system using layers of sand and activated carbon (like the material in some water pitcher filters) to clean up polluted river water in Indonesia. The filter reduced cloudiness and dissolved particles while keeping the water's pH and temperature stable, meeting safety standards for uses like farming and recreation. This kind of low-cost filtration could offer a practical way to make polluted water sources safer in areas without access to advanced treatment plants.
Performance Characteristics of Biological Activated Carbon Adsorption and Filtration in Removing Microparticulates and Natural Organic Matters from River Water
AI summary Read the abstract
Researchers found that a special water filter using activated carbon (like charcoal) can remove up to 94% of microplastics and other contaminants from river water that regular filtration systems often miss. The catch: running water through the filter too slowly for too long causes it to clog, so treatment plants need to find the right balance between cleaning the water thoroughly and keeping the system running smoothly. This matters because it points to a practical way to reduce microplastics and other pollutants in the water we drink, which is increasingly showing up in rivers that supply our tap water.
Performance of Powdered Activated Carbon Adsorption/Membrane Filtration System for Treating the River Water with a High Particulates and Natural Organic Matters
AI summary Read the abstract
Researchers evaluated a combined powdered activated carbon (PAC) adsorption and membrane filtration system for treating river water containing high levels of micro-particulates including colloids and microplastics, as well as natural organic matter such as total organic carbon and taste-and-odor compounds. The system demonstrated improved removal of both particulate and dissolved contaminants compared to conventional clarification processes.
Detection and Characterisation of Microplastics in Waste-Water Treatment Plants, Kashmir, India.
AI summary Read the abstract
Researchers found tiny plastic particles (microplastics) in wastewater treatment plants in Kashmir, India, which matters because these plastics can end up in our water supply and potentially harm human health. The good news: they tested a cheap, simple filter made from sand and charcoal that removed over 99% of microplastics, offering a promising low-cost solution for communities without access to expensive water treatment technology.
Microplastic pollutants in water: A comprehensive review on their remediation by adsorption using various adsorbents
AI summary Read the abstract
This review covers the different materials scientists are developing to filter microplastics out of water, including biochar, activated carbon, sponges, carbon nanotubes, and newer hybrid materials. Each material has trade-offs in terms of cost, effectiveness, and environmental impact, but combining different approaches shows the most promise. The research is important because better water filtration methods could directly reduce the amount of microplastics people consume through drinking water.
