A review of plant fibers and their sorption property for wastewater treatment and water filter production
摘要
While the industrial revolution has promoted the quality of human life, today we have been affected by its environmental consequences. Industrial wastewater is one of the major sources of pollution that should be decontaminated before entering into the nature or being reused. Since most conventional filters are oil-based and non-renewable, this review focuses on the sustainable filtration process. Plant fibers can be used to produce water filters by which individuals can perform a healthy water filtration. Among such plants, milkweed, kenaf, flax, coir, Luffa, Agave, jute, etc. can be noted. These biodegradable fibers can be the ideal replacement for man-made, synthetic, and petroleum-based fibers. Lignocellulosic fibers are able to decontaminate the polluted water through the sorption of the contaminants. In this paper, we review the history of natural fibers' applications in wastewater treatment and the role of each plant in water purification is described. We also examine relevant patents to demonstrate the industrial applicability of natural fibers. By using sustainable methods, we hope to achieve the harmony with the environment.
