A reactor arrangement for performing, by means of at least one solid reaction member(s), a biological or chemical transformation, or physical or chemical trapping from, or release of agents to, a fluidic media in a continuous process. The arrangement comprises at least one reactor with a cylindrical reaction vessel (11) in which at least one reactor a transformation device (100) has been mounted. The vessel (11) comprises at least one inlet port (30) in the vicinity of its bottom wall (18) and at least one outlet port (40) arranged in the vicinity of its upper end portion. Each inlet port (30) is connected to a fluid supply member (300) configured to be submerged below the fluid surface level in a pool or a pond. The fluid supply member (300) comprises at least one inlet opening (301) configured to continuously supply a fluid from the pool or the pond to the vessel (11). Each outlet port (40) is configured to continuously let out the fluid from the vessel (11) to the pool or the pond via the outlet port (40). Further a method of using the reactor arrangement is provided.

A method of treating a sulphate-bearing stream which includes the steps of hydrolysing aluminium sulphate to produce a chemically-reactive aluminium trihydroxide and sulphuric acid, adding lime to immobilize the sulphuric acid as gypsum and using the aluminium trihydroxide to remove sulphate from the sulphate-bearing stream without interference of sulphate derived from the aluminium sulphate used as an aluminium source in the hydrolysis step.

An improved system and method for extracting volatile organic compounds (VOCs) such as ammonia from leachate water. Uses specialized pressurization of leachate water to extract VOCs which may then be recaptured in more highly concentrated water to reduce overall volume of contaminated water.

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.

Produced in an ice that can be added to water or drink to improve the flavor thereof. Provided is a mineral-containing composition containing potassium ions the concentration of which is the highest of the metal ions present in the mineral-containing composition.

A floating dispenser holder having a platform supporting a dispensing cartridge in a dispensing condition and a canopy extending over the dispensing cartridge located on the platform.

Provided is a method of producing a liquid mineral extract containing an abundant amount of potassium that is a mineral component extremely important for humans. A mineral is extracted from activated carbon of a plant-derived raw material using an aqueous solvent.

Compounds, compositions and methods are provided for reducing, inhibiting, or preventing corrosion of a surface, using a polyester polyamine compound. The polyester polyamine compound having a structure corresponding to Formula 1 or 2, or a salt thereof:

##STR00001##

wherein R.sub.1 is independently alkylene; R.sub.2 is independently hydrogen or —COR.sub.4; R.sub.3 is independently alkyl, alkenyl, aryl, or alkaryl; R.sub.4 is independently alkyl or alkenyl; R.sub.10 and R.sub.11 are each independently hydrogen, alkyl, or alkaryl; m is an integer from 1 to 10; n is an integer from 3 to 10; and wherein at least one R.sub.2 is —COR.sub.4.

A process is provided for separating hydrophobic material from a mixture of hydrophobic and hydrophilic material using peptide-based amphiphilic organogelators.
