摘要： A method for increasing the quantity of dissolved oxygen in water includes addition of an oxidant to the water to increase the oxidation-reduction potential (ORP) of the water to between about 400 and 850 mV, followed by electrolysis to generate oxygen gas. The voltage applied to the electrolytic cells during electrolysis is less than 300 mV. The dissolved oxygen content of the water exiting the electrolytic cell is about 90% of saturation to super saturation.

摘要： The present invention relates to a method for managing the polarity-reversal frequency of at least one pair of electrodes in an electrochemical reactor for water electrolysis, wherein in said method: a fluctuation in the hydrogen potential (pH) of the water is observed while carrying out a comparison of the pH measured at a given moment with a previous measurement or a predetermined initial value; an amount of treatment agent, in the form of an acid or base, is injected into the water on the basis of said observed pH fluctuation so as to adjust the pH to around a defined set point; the polarity-reversal frequency of said electrodes is calculated on the basis of the temperature of the water, said pH fluctuation, and said amount of agent injected, said method being characterized in that it involves: estimating the total alkali strength on the basis of said injected amount and said pH fluctuation so as to keep the complete alkalinity titration (CAT) at a minimum level; and anticipating the fluctuations in the pH relative to the preceding estimates of the amount of treatment agent injected so as to stabilize said pH at a set point, and readjusting the complete alkalinity titration estimate and the calculation of said polarity-reversal frequency.

摘要： The invention relates to a method, device and use of said method for biological elimination of metal elements present in water. According to the inventive method, the water which is to be treated is partially oxygenated by specific aeration prior to percolation, using a biological filter comprising a bed of filter material supporting bacteria. The inventive method comprises a step involving the measurement of at least one parameter which is constituted by the oxidation reduction potential of the aerated water prior to passing through the biofilter, a stage in which the measuring signals are transmitted to a calculator and a comparison is carried out for the signal representing the value of the parameter which is measured at at least one lower limit determined according to the measurement carried out in a second measurement stage for a parameter representing the pH, and a stage in which the air flow is corrected by a signal which is determined by the calculator according to the two previous stages.

摘要： A central controller is used in a treatment method and system for removing at least one of nitrogen or phosphorus from wastewater. Based on data received from a plurality of sensors, each of which is coupled to a component of a wastewater treatment system, a control signal is sent from the central controller to at least one chemical delivery system, which dispenses at least one chemical compound into the wastewater in an amount effective to reduce the level of nitrogen or phosphorus in the wastewater.
