Summary

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.

Study Type Environmental

The research aim was to remove as many microfibres, microplastics and harmful bacteria as possible from the polluted water to produce suitable water for reuse. The test water was the effluent from the municipal wastewater treatment plant in Shalek Valley. A pilot plant with a ceramic SiC filter for membrane filtration and ozonation of filtered water was set up to remove suspended solids, micro-fibres, microplastics, and harmful microorganisms. The Microfibers Detection System was developed to identify microfibers on-site. The results showed that the microfiltration system combined with ozone treatment effectively removed total suspended solids, microfibres, microplastics and microorganisms. A detection system method for identifying microfibres and microplastic particles was used to determine how many microfibres and microorganisms were identified by membrane filtration and ozonation. The study showed that membrane filtration successfully removed all microfibres, 88% of total coliforms and 93% of E. coli . After additional ozonation, we achieved a 100% removal rate of total coliforms and a 100% removal rate of E. coli . The treated water (effluent from the municipal wastewater treatment plant) can be used for specific purposes, such as agricultural irrigation or enhancing bathing waters near the plant's water effluent.
