As part of a webinar focused on enhancing biological filtration processes – How Filtralite can enhance your biological wastewater and drinking water filtration process, organized by Filtralite and Smart Water Magazine – Geir Norden, Research and Development Manager at Filtralite, provided a detailed exploration of Filtralite’s advanced capabilities for contaminant removal. Norden began by explaining the unique properties of Filtralite, stating, “Filtralite is a ceramic material that is crushed and sieved into particle sizes typically ranging from 0.8 to 5.0 mm. Due to its highly porous structure, we recommend soaking before use. With a specific surface area exceeding 1500 m²/m³, Filtralite is exceptionally well-suited as a biofilm carrier.”
He highlighted Filtralite’s ability to optimize biological processes such as nitrification and denitrification, supported by its high specific surface area, which facilitates robust biofilm growth. Case studies from Norway and China underscored Filtralite’s effectiveness. At Norway’s VEAS treatment plant, it helped reduce COD, BOD, and suspended solids, while in Hong Kong’s Tai Po facility, it achieved ammonia reductions of 80-90% and manganese reductions of 75%, significantly cutting chemical usage. Norden noted that Filtralite’s lightweight composition simplifies transportation and installation, and its lifespan of up to 25 years reduces replacement needs and environmental impact.
In drinking water applications, Norden emphasized Filtralite’s ability to simultaneously remove ammonia, iron, and manganese using biologically driven processes. He shared data from Olofström, Sweden, where Filtralite reduced manganese levels by 90%, demonstrating its versatility across diverse settings. Norden concluded by highlighting Filtralite’s role in reducing operational costs and enhancing sustainability, making it a reliable and effective solution for municipal and industrial water treatment.
