Abstract
Cleaning in place (CIP) in the brewhouse and CIP and disinfection in cellar plants are very intensive and expensive procedures, since many cleaning solutions are needed. New types of cleaning technologies are required to comply with the environmental protection, safety, cost concerns, and stewardship issues that are part of the modern business climate. A new highly disinfectant, pH neutral, metastable water agent with high bactericidal, viricidal, and fungicidal properties has been developed based on an electronic chemically activated module. Using optimized diaphragm cell electrolysis, Annolyte is produced from water and salt on two electrodes (anode and cathode) directly in the CIP plant and can be stored in a small tank and recovered as concentrate and final solution. The solution has a high redox and cleaning potential, is nontoxic, and has a chemical-physical effect on microorganisms. No trichloromethane is formed, so the formation of chlorophenol is not possible. Corrosion formation is also not possible, and stainless steel and elastomers are not attacked. The aims of this new cleaning and disinfection technology is the replacement and reduction of traditional cleaning and disinfectant solutions; lowering of AOX (absorbable organic halides) values in wastewater; prevention of reinfection via the fresh water rinse; perfect cleaning and microbiological values without having to worry about health concerns to the user; no storage and logistics costs; lowering of consumption costs; and simple integration into the plant, as well as increased process security.

S�ntesis
Limpieza en sitio (CIP) en el cocimiento y el CIP y desinfecci�n en las cavas son procedimientos muy intensivos y costosos, considerando que se necesitan muchas soluciones diferentes de limpieza. Nuevos tipos de tecnolog�as de limpieza son necesarias para cumplir con la seguridad, protecci�n del entorno, costos y temas gerenciales que son ahora parte del clima empresarial moderno. Se ha desarrollado un agente meta estable en agua con propiedades altamente bactericidas, viricidas y fungicidas; este agente poderosamente desinfectante y con pH neutro est� basado sobre un m�dulo electr�nico activado qu�micamente. Annolyte es producido de agua y sal utilizando electr�lisis optimizada con c�lulas en forma de diafragmas. Se usan dos electrodos directamente en la instalaci�n del CIP y puede ser almacenado en un peque�o tanque y recuperado como un concentrado o como una soluci�n de uso. La soluci�n tiene un alto potencial redox y fuerte potencial limpiadora, pero no es t�xico; su efecto sobre los microorganismos es qu�mico-f�sico. No se forma triclorometano por lo que no es posible que se produzca clorofenol. Acero inoxidable y elast�meros no son atacados ya que no es posible que cause corrosi�n. Los objetivos de esta nueva tecnolog�a de limpieza y desinfecci�n es la sustituci�n y reducci�n del uso de soluciones tradicionales, reduciendo los valores AOX (hal�genos org�nicos absorbibles) en los efluentes; la prevenci�n de reinfecci�n mediante el agua fresca de enjuague; excepcionalmente buenos efectos microbiol�gicos y de limpieza sin un efecto da�ino sobre el usuario; cero costes de almacenaje y log�stica; reduciendo los costos de consumo; mayor seguridad para el proceso e integraci�n sencillo a las operaciones de la planta.
