ClearThe application of different methods for indirect microbial development assessment in pilot scale drinking water biofilters
Researchers evaluated methods for monitoring biofilm growth in biological activated carbon filters used in drinking water treatment. Different indirect measurement approaches varied in accuracy and practicality. Reliable biofilm monitoring is important for maintaining filter performance and ensuring treated water is free from microbial and chemical contaminants.
Performance of Conventional Drinking Water Treatment Plants in Removing Microplastics in East Java, Indonesia
This Indonesian study tested two conventional drinking water treatment plants in East Java for their ability to remove microplastics, finding that full multi-stage treatment achieved significant reduction but did not eliminate all particles. The results show that conventional water treatment partially protects consumers but may not prevent all microplastic ingestion through drinking water.
Comprehensive Evaluation of Advanced Water Filtration Techniques: Assessing Efficacy in Removing Hazardous Contaminants and Inhibiting Bacterial Proliferation
Researchers designed an innovative eco-friendly filtration system and compared its performance against reverse osmosis, activated carbon, and LifeStraw filters for removing nitrates, nitrites, and sulfates from water sources while assessing bacterial presence post-filtration.
Microplastic Contamination in Drinking Water Treatment Systems: A Case Study of Bedadung River Jember
Researchers traced microplastic contamination through the Bedadung River water treatment chain in Indonesia, from intake to consumer taps, at seven sampling points. MPs were present throughout the system, with concentrations declining through treatment stages but not reaching zero, indicating residual MP exposure in treated drinking water.
Comprehensive Evaluation of Advanced Water Filtration Techniques: Assessing Efficacy in Removing Hazardous Contaminants and Inhibiting Bacterial Proliferation Translational Medical Science
Researchers designed an innovative eco-friendly filtration system and evaluated its performance against reverse osmosis, activated carbon, and LifeStraw filters for removing nitrates, nitrites, and sulfates from water while monitoring bacterial levels post-filtration.
Water Quality Analysis And Instant Filtration & Disinfection In Bottle (BRAINY BOTTLE)
This study examined water quality challenges and waterborne disease risks from contaminated water sources, proposing an in-bottle filtration and disinfection system as an accessible solution for providing safe drinking water.

Researchers characterized microbial community composition in a wastewater treatment system, examining how treatment stage and operational conditions shape bacterial diversity and functional potential relevant to pollutant degradation.
Assessment of microplastic contamination in drinking water from an italian plant: An analytical study
Researchers analyzed microplastic contamination at multiple treatment stages in a drinking water plant in northern Italy that processes turbid river water supplemented with groundwater, quantifying particles through sedimentation, flocculation, sand filtration, activated carbon adsorption, and disinfection stages.
Effectiveness of Screening Models in Improving the Quality of Cenrana River Water as a Drinking Water
This study assessed the water quality of the Cenrana River in Indonesia as a potential drinking water source and evaluated the effectiveness of different screening and treatment models, identifying key contaminants and recommending suitable treatment approaches for the community.
Microplastics Removal from Treated Wastewater by a Biofilter
Researchers evaluated a pilot-scale biofilter for removing microplastics from secondary wastewater treatment effluent, finding it effectively polished treated wastewater before environmental discharge by capturing particles across multiple filter zones.
Microfibres and coliforms determination and removal from wastewater treatment effluent
Researchers tested a ceramic silicon carbide filter pilot plant for simultaneously removing microfibers, microplastics, and coliform bacteria from municipal wastewater treatment plant effluent. The ceramic filter achieved high removal efficiency for both microplastic particles and fecal indicator bacteria, demonstrating a combined treatment approach suitable for producing reclaimed water for reuse.
Identification of microplastics and their removal efficiency in drinking water treatment plants in tropical areas: a case study of the Dago Pakar drinking water treatment plant, Bandung, Indonesia
This case study tracked microplastics through different treatment stages at a drinking water plant in Bandung, Indonesia, finding that plastic levels were higher during the rainy season and that particle sizes between 300-1000 micrometers dominated. The treatment plant reduced microplastic counts, but the study assessed how effectively each treatment step performed across seasons and times of day. The findings contribute to understanding how well conventional water treatment removes microplastics in tropical developing-country settings, where infrastructure may differ from Western facilities.
Improving Quality: Exploring Ceramic Water Filters in Developing Communities
This dissertation investigated the manufacturing quality and performance of ceramic water filters (CWFs) used in developing communities, using empirical models based on flow rate and pore diameter to predict microbial removal efficiency and identify key quality control factors.
A solution for controling microplastics in drinking water
Researchers developed and tested a system for controlling microplastic contamination in drinking water, reporting on removal efficiency at levels relevant to public health. The approach offered effective microplastic reduction from drinking water sources including tap and bottled water.

Conventional and biological treatment for the removal of microplastics from drinking water
Researchers examined microplastic removal by a full-scale drinking water treatment plant, finding that conventional coagulation-flocculation-filtration processes and biological filters with granular activated carbon effectively reduced microplastic concentrations in treated water.
Removal efficiencies of microplastics of the three largest drinking water treatment plants in Bangladesh
Researchers evaluated the three largest drinking water treatment plants in Bangladesh and found that while conventional treatment removed a significant portion of microplastics, treated water still contained plastic particles. Removal efficiency varied depending on the treatment process used, with some plants performing better than others. This highlights that current water treatment infrastructure may not fully protect people from microplastic exposure through drinking water.
