Water management of two shallow urban eutrophic lakes Available to Purchase

The efficiency and effects of aluminium sulphate on water quality of two shallow urban eutrophic lakes of Madrid (Spain) is reported. Almost all the controlled variables improved with the treatment, especially nutrients, pH and transparency. The application of the method during spring and summer reduced nutrient content for the remainder of the seasons. However, phytoplankton density in both lakes needs supplementary measures for long-term control. The treatment seems not alter fish populations.
