Abstract: The present invention relates to a water remediation system and accompanying method. The method comprises remediation by reducing the concentration of nutrients in the water and dosing the water with metal ions. It has been found that through a combination of reducing nutrients present in the water and treating with metal ions, the requirement to treat with high chemical dosages is removed.

Abstract: L'invention concerne un procédé de renouvellement d'eau dans un circuit de filtration pour piscine. Le procédé de renouvellement d'eau met en oeuvre les étapes suivantes: - mesure de la précédente quantité d'eau renouvelée dans le circuit de filtration (2) de la piscine; et - mesure d'un paramètre de propreté (C) de l'eau présente dans le circuit de filtration (2); puis - renouvellement d'une quantité d'eau (VRj) dans le circuit de filtration (2), en proportion de la valeur d'un produit entre, la précédente quantité d'eau renouvelée (VRj-1) dans le circuit de filtration (2) et un facteur correctif (Cj), le facteur correctif étant un rapport entre le paramètre de propreté (C) mesuré et une valeur de référence du paramètre de propreté.

Abstract: A heating system of a managed fluid system can include a heat exchanger and a first temperature sensor device that measures an inlet temperature of a fluid flowing into the heat exchanger. The heating system can also include a second temperature sensor device that measures an outlet temperature of the fluid flowing out of the heat exchanger. The heating system can further include a controller communicably coupled to the first temperature sensor device and the second temperature sensor device. The controller can receive inlet temperature measurements made by the first temperature sensor device and outlet temperature measurements made by the second temperature sensor device. The controller can also evaluate the inlet temperature measurements and the outlet temperature measurements using at least one lookup table and at least one algorithm. The controller can subsequently determine an input rate of fuel used to heat the fluid flowing through the heat exchanger.
