AI Technical Summary
Existing quartz sand filter media presents challenges in water treatment applications, necessitating the development of high-precision, fouling-resistant, long-life, and low-cost filter media to drive the water treatment industry towards a more environmentally friendly and efficient direction.
Using recycled waste glass as the base material, high-precision anti-fouling filter media is prepared through magnetic separation, crushing, sieving, calcination, activation treatment and nano-coating technology. The particle size and shape are controlled, and a hydrophilic and oleophobic surface is given and a permanent negative charge is formed.
The prepared high-precision anti-fouling filter media has high filtration accuracy, can effectively remove suspended solids and oil from water, has stable chemical properties, will not cause secondary pollution to water quality, and has significant economic and environmental benefits.
