A system and method for controlling the accelerated remediation of the water of an aquatic facility using at least one sanitizer sensor, a pH sensor, a temperature sensor and a chlorine dioxide sensor all interfaced with a programmable controller that is programmed to implement an accelerated remediation cycle and configured to calculate a Ct value of the water chemical feed system. The programmable controller activates a chemical feed system to supply an acid, an oxidizer and a chlorite ion donor to a conduit to form chlorine dioxide that is supplied to the water until a desire Ct value is reached.

A floating sports equipment pool chlorinating system dispenses a sanitizing chemical into a body of water for sanitizing water. The system includes a sports equipment-shaped housing, possibly shaped as a helmet or ball. The housing has an outer and inner shell arranged in a spaced-apart relationship. The space between the shells is filled with a closed-cell extruded polystyrene foam, like Styrofoam, which enables the housing to float. The inner shell forms a cavity that is sized and dimensioned to receive and retain a sanitizing chemical, such as a chlorine tablet. The shell has a top region that forms a slot, a bottom region that forms multiple outlet holes, a front region that forms a front opening. All the slots, holes, and openings are in fluid communication with the cavity. The top region of shell, has a spherical shape sufficiently large to enable wind to carry the housing across the water.

An exemplary, nonlimiting embodiment of the present invention relates to a water treatment and filtration system for reducing the concentration disinfection byproducts within drinking water treated by municipal drinking water treatment plants. This water treatment and filtration system reduces the concentration of disinfection byproducts, which may include trihalomethanes (THM) and haloacetic acids (HAA5), in drinking water using a clever sequencing of treatment techniques that intentionally promote formation of the disinfectant byproducts prior to filtration to effectively remove disinfection byproduct precursors and prevent subsequent formation of disinfection byproducts downstream during distribution. Moreover, this water treatment and filtration system can be retrofitted to a variety of municipal drinking water treatment plants and is designed to easily scale if demand for drinking water within the municipality increases.

A swimming pool water sanitizing unit with an ozone generator and a separate ultraviolet (UV) reactor chamber within the same housing unit. The ozone generator may include a water jacket gap between the ozone generator chamber and the outer casing that passes pool water through the gap for cooling. Either of the ozone generator and the UV reactor chamber may include UV intensity sensors to help predict the life of the UV bulb therein. The UV reactor chamber may include rotating water paddle blades to stir up the water within the chamber for enhanced exposure to the UV light. A diverter valve enables diversion of ozone enriched fluid to the pool pump in addition to the UV reactor chamber.

The present invention relates to a method for recovering metals using an adsorbent, which comprises preparing a leachate comprising metal ions and cyanides, wherein the metal ions comprise gold ions and copper ions; and in a state where the leachate has a cyanide (CN) concentration of 0.1 ppm or greater, adding to the leachate an adsorbent, which has an open circuit potential value between the open circuit potential value of the gold ions and that of the copper ions; and selectively adsorbing the copper ions to the adsorbent.
