摘要:
The invention relates to an apparatus for the production of oxidizing biocides. The apparatus can be used as a remote production system where the product is stored use or it can be an in situ production system where the product can be in fluid connection with the system being treated. The preferred product of the system is chloramine, which can be produced in a stable form with this apparatus.
摘要:
The invention relates to a method for preparing a solution including monochloramine, which includes the steps of: a) in an electrolyser including an anode area and a cathode area separated by a membrane limiting the migration of hypochlorite ions, forming hypochlorite ions in the anode area by means of the oxidation of chloride ions in an aqueous solution, and forming ammonium ions in the cathode area by means of the reduction of nitrate and/or nitrite ions in an aqueous solution; and b) reacting the ammonium ions with at least one portion of the hypochlorite ions, with a molar ratio of hypochlorite ions to ammonium ions no lower than 1, resulting in the formation of monochloramine.
摘要:
The invention concerns a synthesis method for a solution with high grade chloramine obtained by reacting a hypochlorite solution on a compound ammonia mixture.
摘要:
An apparatus and methods to produce synergistic mixtures (or combinations) of haloamines to control growth of microorganisms in aqueous systems are disclosed. The apparatus and methods to produce synergistic mixtures entails producing a batch quantity of a haloamine and converting part of the haloamine to a second haloamine species to form the synergistic mixture.

A process and reactor for the gas-phase reaction of commercially available gases in the presence of an inert carrier gas to from product gas. The reactor (10) has an outer shell tube (12) and an inner tube (16), both of which feed reaction chamber (18). At last one first commercially available fed gas is fed to outré tube (12) via first inlet (13). One or more inert gases is fed to outer tube (12) via second inlet (14). In the case of chloramines gas formation, chlorine gas reacts with ammonia. Gas at reaction zone (20) in reaction chamber (18), which is heated by one or more heating elements (22). The product gas stream exits reaction chamber (18) via discharge tube (26).
摘要:
The present invention provides a method for producing chlorine dioxide by reducing sodium chlorate with a reducing agent in the presence of a strong acid comprising feeding ammonium salt to the reactor to produce also chloramine. The present invention also provides a method for disinfecting water.
摘要:
The invention relates to a production method for producing stable chloramine. The method allows for the production of stable chloramine with the use of concentrated Chlorine source and concentrated amine source and agitation during production. The method produces a chloramine that has a pH of at least 5 with a most preferred pH of at least 7 or greater.
