A method and apparatus is provided for treating water with already-slaked lime to arrive at a lime slurry that is in a solution or suspension, and delivering the thus treated water to a separating device which separates grit particles therefrom, to recover a high quality lime/water solution or suspension. An automated system controls the addition of lime and water to a lime mixing vessel. An acid wash system is provided which comprises an automated method and apparatus for removing scale buildup, for delivering an acid wash solution to the lime mixing vessel, the lime slurry holding tank and/or the delivery system, or any of them, thereby dissolving the scale buildup.

An ion removal system includes: an ion removal device including a hard water storage configured to store hard water and a fine bubble generator configured to generate a fine bubble to supply the hard water storage with the fine bubble, for removing a metal ion from the hard water by adsorbing the metal ion in the hard water to the fines bubble in the hard water storage and crystallizing and precipitating the adsorbed metal ion; and a particle feeder configured to bring a particle containing a same element as that of the metal ion into the hard water at a feeding point, the feeding point being located upstream of the hard water storage or located in the hard water storage.

The present invention relates to a water treatment apparatus (1), in particular for supplying water-conducting and/or water-heating household appliances or appliances for producing and preparing food and/or beverages using treated drinking water, e.g. automatic drinks machines, automatic coffee machines, ice machines, cooking and baking appliances, steam generators or high-pressure cleaners, air conditioners or the like using treated water, comprising an agent (3) present in solid form for reducing mineral precipitates. It is characterized in that a first medium which influences the dissolution behavior of the agent for reducing mineral precipitates is provided.

A chemical delivery system is provided. The chemical delivery system includes a strand of material having a plurality of chemical delivery tablets secured thereto. The strand of material can be inserted into a drain pipe opening and retained within the drain pipe by a retention disc and/or a removable cap. The chemical delivery tablets are measurably consumed as fluid or other condensate material flows through the drain pipe. The strand of material may then be readily replaced with a new strand on a period basis without necessitating disassembly of the pipe thereby preventing growth of algae or other organic material in the drain pipe.

A method and system for the in situ treatment of at least one contaminant in soil or water is disclosed herein. The method comprises placing an opening into the soil and into at least a portion of subsurface water and thereby filling at least a portion of the opening with the water, placing a reactant in the opening, and moving a portion of the water proximate the bottom of the opening toward the water proximate the top of the opening, thereby increasing the homogeneity of the reactant in the water.

Methods of treating bodies of water or wastewater are disclosed herein. The method can include providing one or more water treatment compositions comprising a compound with a peroxide group or a carbonate salt, a binder, a fibrous material, and an inert material, where the compound, binder, the fibrous material, and the inert material are combined into the form of an integral product, and immersing the integral product into a body of water or wastewater. The method can include a dispensing apparatus for holding such integral products such that the step of immersing the tablets into a body of water or wastewater is accomplished by immersing the dispensing apparatus into the body of water or wastewater. The dispensing apparatus can be arranged such that when integral products are placed in the apparatus the integral products form a vertical column.

A device for treating harmful algal blooms using modified clay includes a power system, a screw conveying storage bin storing and conveying modified clay to a mixed flow system, the mixed flow system that continuously disperses the modified clay in water which is pumped in in site and endowed an impulse so that an adjustable turbulence is formed to instantly adopt the fed powder and then make sure the slurry uniform and ripened, a high-pressure sprinkling system for pressurizing a ripened modified clay slurry and sprinkling the slurry onto the surface of the bloomed water, and a central control system that controls the whole auxiliary device.

A system and method for delivering silver ion biocide is described herein. The systems described relate to passing water from a water system through a silver ion release module and optional high-concentration silver ion release module. The system includes an analyzer, detector, and/or controller for monitoring the concentration of silver ion and adjusting the flow path, flow rate, temperature and/or pH of the water in order to obtain the desired concentration of silver ion. The system optionally includes other metal ions released into a water system, the concentration of which may be used to automatically calibrate the described system and/or cause the system to take actions based on the measured concentration of silver ion or of the second metal ion.

The present invention discloses a method for controlling surface-inhabiting pests in an aquatic system, in particular cyanobacteria and harmful algal blooms (HABs), comprising spreading on the surface of the aquatic system a buoyant composition comprising a water disinfectant, preferably an oxidizing compound, and a floating agent. The invention further relates to compositions and methods for their preparation and use.

Disclosed is a device for services related to providing hot water, to water treatment, to the cleaning of any fixed or mobile surfaces like lines for proving potable water or food liquid, remarkable in that it is mobile, includes an internal chassis housing in the lower part a tank for recovering possible fluids and a subassembly for producing hot water with at least one condensing boiler associated with at least one module for supplying gas formed by a plurality of gas cylinders of the carburation type storing in their internal volume the gas in the liquid state in the lower part and in the gaseous state in the upper part, the gas cylinders being disposed in the internal chassis substantially horizontally and with the opening orifice oriented upwards so that the end of the pipe for passage of the gas opens onto a larger elongated gaseous part.
