Abstract Algal Turf Scrubbers (ATS) are water treatment devices that use light and nutrients in the (waste)water to grow periphyton community; undesirable chemicals are removed by physical, chemical and biological processes. So far, most ATS systems were operated in water bodies with relatively high nutrient concentrations. Little is known about the performance of ATS under low concentration of phosphorous (P), yet there are potential applications where such conditions are met. The paper presents a series of experiments that focus on the implementation of small-scale ATS systems to eliminate P from natural swimming ponds (SP). SPs are typically subject to fluctuating P concentrations and require the maintenance of very low levels of P (< 10 μg L-1) in order to prevent undesirable algal growth. ATS systems proved to be capable of maintaining such low levels, both in laboratory and field conditions.
