Long-term reduction of the nutrient content of the water flowing into the water reservoir.
Phosphorus precipitation is an effective method of reducing the nutrient content of the water column. It is therefore a suitable method of quality care, especially for bathing and ornamental water reservoirs. In some cases, it is advantageous to treat the water already at the inlet to the water reservoir.
Precipitation of phosphorus as an essential nutrient for the development of phytoplankton in stagnant surface waters at the inflow to a water reservoir is based on the same principle as precipitation of phosphorus on a body of water. By dosing the coagulant (precipitant), the dissolved phosphorus and phytoplankton cells are flocculated. This reduces the nutrient load of the reservoir and reduces turbidity (increases the transparency of the water column).
However, the difference is in the app. When precipitating phosphorus at the inlet, very small doses of coagulant are applied by means of a dosing pump into the inflow watercourse. Dosing is carried out over a longer period of time, usually from the spring filling of the tank to the end of the growing season.
An automatic precipitation unit equipped with a coagulant storage tank, a dosing pump, a control unit enabling remote control and probes for continuous monitoring of the basic parameters of the water (flow rate, pH, temperature, conductivity) is installed at the inlet to the water reservoir.

Water Dam Jordán
Near Tábor, we built an automatic precipitation station that continuously treats the water, feeding Malý Jordán and Jordán reservoirs with coagulant.
Tyrš Lido
The charming area of the natural Tyrš lido attracts the inhabitants of Rakovník and its surroundings on hot summer days. We have been helping to take care of water quality here since 2019.
