Biological methods of removing phosphorus compounds from wastewater as applied currently at treatment plants may no longer be regarded as sufficient. They can therefore be augmented by physico-chemical methods raising the efficiency of the wastewater treatment system. Indeed, almost all large urban wastewater treatment plants practise precipitation of phosphorus using salts of iron and aluminum in the form of chemical coagulants. The search is nevertheless ongoing for new ways of assisting with the removal of the biogenic element from wastewater, e.g. by dosing bentonites, fly ash and post-technological sludge from water treatment stations, or even unconventional organic sorbents such as rice husks. A further unconventional material in P-removal from wastewater may take the form of powdered mineral materials. Against that background, the work presented here offers the results of laboratory-scale trials on P-removal using brick dust and powdered keramsite (expanded clay).
