  • Small domestic wastewater treatment using waste materials

    Phosphorus pollution of groundwater from small wastewater system is often considered as a major threat for aquatic habitats. Recirculating biofilters are often used to treat small wastewater systems without significant removal of phosphorus. In this paper, a low-cost waste material (dried alum residual) in pre-treated effluents from recirculating biofilters was examined. Two different types of ...
