Abstract A compact three-in-one water treatment process, combining a flocculant, a fibrous super-bridging agent, and a screen-based floc retention system, simultaneously improves water treatment and sludge dewatering.The presence of fibrous materials allows for the Sweatpants formation of very large flocs, efficient floc separation via screening (without settling), and sludge dewatering through a compact press-filter system.The implementation of this three-in-one process is possible due to the formation of very large fiber-based flocs.The sludge containing fibers was subsequently dewatered using a screen-based press filter without further chemical addition.The use of fibers also significantly improved the removal of total organic carbon, nanoplastics, and microplastics.

This three-in-one process could be used for decentralized water treatment in drinking water and wastewater applications in small cities, marginalized communities, and developing countries.The compact process, which also performs sludge Glassware Cleaning Brushes dewatering, would reduce the risks associated with mismanaged sludge to the environment and human health.
