Furnace Slag

The suitability of iron-ore and blast furnace slag for subsurface flow (SSF) constructed wetlands was studied over a period of four months. Dairy farm wastewater (TP 45 mg l-1) was percolated through buckets planted with reed (volume 9.1 l; hydraulic load 15 l m-2d-1). One group of buckets was kept under aerobic conditions and the other group under anaerobic conditions, monitored by continuous redox potential measurements. Even at high mass loading rates of 0.65 g P m-1d-1 the slag provided 98% removal efficiency and showed no decrease in performance with time. However, phosphorus fractionation data indicate that the high phosphorus retention capacity under aerobic conditions is to a great extent attributable to unstable sorption onto calcium compounds (NH4Cl-P). Phosphorus sorption of both the slag (200 μg P g-1) and the iron-ore (140 μg P g-1) was promoted by predominantly anaerobic conditions due to continuous formation of amorphous ferrous hydroxides. None of the substrates had adverse affects on reed growth.

Retention Capacity

The phosphorus retention capacity of 24 New Brunswick soils and interrelationships with clay, organic matter, iron, and aluminum were investigated. Retention capacity varied from 7.1 to 59.6 mmoles per 100 g with a mean value of 24.9 mmoles. On the basis of partial and multiple regression analyses, it was concluded that aluminum plays a dominant role in phosphorus retention. A significant relationship was also found between retention capacity and organic matter but no relationship with clay or iron.
