Controlled formaldehyde fumigation system

Controlled formaldehyde fumigation system.

A comparative study of formaldehyde (HCHO) fumigation was carried out by controlled vaporization, using an electric vapor generator, and by the Formalin-permanganate method. Determination of vapor levels as well as bactericidal action showed the generator to be more effective. Maximum achievable fumigant levels were temperature dependent and related to the equilibrium vapor concentration of HC...

Automated Fumigation and Neutralization Systems for Formaldehyde Gas

Decontamination of poultry or animal housing areas over the last few decades has often involved the use of formaldehyde gas which, although very effective [l, 2,3,4], is a known carcinogen [4]. Various approaches have been used to release the gas, which is usually generated by adding formalin to potassium permanganate. The process by which the gas is generated has varied over the years from man...

Comparative efficacy of 3rd generation quaternary ammonium compounds and formaldehyde for fumigation of operation theatres

Objectives: The aim of this study was to evaluate and compare the efficacy of 3 rd generation quaternary ammonium compounds and formaldehyde for fumigation of operation theatres. Materials and Methods: Fumigation and fogging of operation theatres by formaldehyde and 3 rd generation quaternary ammonium compounds respectively were done by standard procedures. A total of 144 samples (swabs as well...

Disinfection of hatching eggs by formaldehyde fumigation – a review Desinfektion von Bruteiern durch Begasung mit Formaldehyd – eine Übersicht

Microbial contamination of hatching eggs is a main concern of poultry producers as it causes poor hatchability and chick performance. It is evident that high standards of hygiene must be practised in hatcheries in order to minimise the soiling of eggs but, further disinfection of eggs is also necessary to limit bacterial numbers. Methods used include the application of disinfectants by wiping, ...
