- Dr. Drizo is one of the four world pioneers who established the research on the use of various iron, aluminum and calcium based materials (both natural and industrial by-products) for phosphorus removal from wastewaters in early 1990s [1-2].
- PhosphoReduc Filtration Media are modified natural materials that have the following characteristics:
2) Higher Phosphorus retention capacity compared to other materials used in commercial products.
4) Add on value as a phosphorus rich soil amendment that can be used instead of chemical fertilizers.
