A method involving a sorbent designed to capture specifically virus-inactivating solvent-detergent mixtures is described. Its specificity allows the adsorption of these undesirable chemicals with a high capacity in order to treat large amounts of inactivated biological fluids in small-sized columns. Typically, the volume of sorbent that can be used repeatedly is between one quarter and one tent...

As an environmentally friendly method, water jet (WJ) technology plays a significant role in the field of remanufacturing cleaning. The cleaning capacity WJ is severely restricted by pressure, while impact force will be too large and may damage cleaned substrate as well cause energy waste if pressure high. However, adding abrasives, low-pressure (LPWJ) considerably improved. Although abrasive (...

Plate heat exchangers (PHEs) were introduced in the 1930s and were almost exclusively used as liquid/liquid heat exchangers in the food industries because of their ease of cleaning. Over the years, the development of the PHE has generally continued towards larger capacity, as well as higher working temperature and pressure. Recently, a gasket sealing was replaced by a brazed material, and each ...

Data cleaning is, in fact, a lively subject that has played an important part in the history of data management and data analytics, and it still is undergoing rapid development. Moreover, data cleaning is considered as a main challenge in the era of big data, due to the increasing volume, velocity and variety of data in many applications. This paper aims to provide an overview of recent work in...

Food industry cleaning operations must efficiently mitigate any risk of remaining unwanted contamination without consuming large amounts water, chemicals and energy. This study's originality was in analysing the capacity flowing foams to remove Bacillus spores from stainless steel surfaces. A set-up designed allow formation wet flow under three differing regimes: bubble-size rearrangement obser...

Laser cleaning experiments exhibited a higher cleaning efficiency of the laser cleaning upon application of electrochemical potential on an oxidised iron surface. The objective of this study is to clarify the role of such an electrochemical control on cleaning efficiency. Therefore a study by optical spectrometry at normal incidence in the relevant conditions was performed. From these measureme...

BACKGROUND In recent times, it has been proposed to classify endodontic files as single-use items due to a perceived inability to adequately clean the instruments. The purpose of the present study was to quantify the surface debris on files removed from the manufacturer's packaging, and after cleaning using an ultrasonic bath or a thermal disinfector. METHODS Stainless steel and rotary nickel...

Surgical instruments are often strongly contaminated with patients' blood and tissues, possibly containing pathogens. The reuse of contaminated instruments without adequate cleaning and sterilization can cause postoperative inflammation and the transmission of infectious diseases from one patient to another. Thus, based on the stringent sterility requirements, the development of highly efficien...

Campylobacter is responsible for human bacterial enteritis and poultry meat is recognised as a primary source of infection. In slaughterhouses, cleaning and disinfection procedures are performed daily, and it has been suggested that disinfectant molecules might select for antibiotic resistant strains if shared targets or combined resistance mechanisms were involved. The aim of the study was to ...
