Opis:
This paper presents a study on the effect of cleaning factors on the energy consumption of the cleaning process in a CIP system, and the correlation between single components of electricity necessary to perform this process and the cleanliness degree obtained. Studies were carried out in a laboratory cleaning station, wherein a plate heat exchanger contaminated with hot milk was included. The research program was developed according to a 5-level statistical plan. Based on the results, obtained with Experiment Planner 1.0, a regression function of energy requirement considering variables such as: cleaning time, temperature and flow rate of the cleaning liquid via the cleaned exchanger has been developed. Describing this relationship, linear and quadratic functions with double interactions were used. Significance level for the analysis was established at α = 0.05. Correlation analysis between components of the electricity necessary to perform the cleaning process (pump drive and heating of the cleaning agent) and the resulting degree of cleaning of heat exchanger plates was performed.

Opis:
On the base of literature data as well as authors works a review of the state-of-the-art in ablative laser cleaning of surface layers of various constructional materials with encrustation produced in physical and technological processes is presented in the paper. The process and mechanisms occurring in the ablative laser cleaning are described. Three types of the most frequently used lasers offer characteristic advantages understood as average power, pulse operation, wavelength, optical feedback with materiał processed, and fiber delivery. The process of surface layer cleaning of materials and machine elements can be carried out in various -ways. In general, when using pulse laser radiation, five different mechanisms of removal of particles, encrustations, or coatings can be applied. So, the process of removal can be performed via following physical processes: surface vibrations, particles oscillations, thermal expansion of particles (or encrustation), generation of so called detonation wave over surface being cleaned, and laser ablation. Lasers are especially useful for removal of layers from many types of substrates like wood, metals, plastics, composites, stones, ceramics, leather, and others. The important advantage of laser cleaning and surface modification is the capability of processing automation which is related to process repeatability, ease of parameters controlling, possibility of strengthening in zones difficult to access, high precision of interaction and high efficiency as well.

Opis:
The paper presents the selected results of tests on ablational laser removal of polymer lacquer coating with metallic filler (aluminium plates). The fibre laser with the Galvo head of the following parameters: the radiation wavelength λ = 1064nm, the exposition time of the laser impulse τ = 25ns, and the repetition frequency 30-500kHz was used. By changing the power thickness, repetition frequency, and scanning speed various effects of varnish, coating removal were obtained. The melting of the colourless lacquer coat was observed when small power thickness was applied. Multiple scanning with the laser beam of higher power thickness resulted in sequential removal of several to tens of micrometers of the lacquer coating. This technology brings very good perspectives for the renovation of lacquer coating systems in present vehicles (bodies, frames).

Opis:
There are several operations which must do to maximize the performance of tank cleaning. The new advanced technologies in tank cleaning have raised the standards in marine areas. There are many ways to realise optimal cleaning efficiency for different tanks. The evaluation of tank cleaning options means to start with audit of operations: how many tanks require cleaning, are there obstructions in tanks (e.g. agitators, mixers), what residue needs to be removed, are cleaning agents required or is water sufficient, what methods can used for tank cleaning. After these steps, must be verify the results and ensure that the best cleaning values can be achieved in terms of accuracy and reliability. Technology advancements have made it easier to remove stubborn residues, shorten cleaning cycle times and achieve higher levels of automation. In this paper are presented the performances in tank cleaning in accordance with legislation in force. If tank cleaning technologies are effective, then operating costs are minimal.

Opis:
Ultrafiltration (UF) is one of the membrane processes which is mostly used in the dairy industry for the separation and concentration of whey components or fermentation broth. Fouling of UF membranes in the food industry is primarily due to a deposition of microorganisms, proteins, fats and minerals on the membrane surface. Thus, cleaning of the membranes is an essential step of UF separation. The results from investigations of chemical cleaning of a ceramic UF membrane fouled by precipitation of whey components and yeast contained in the fermentation broth are presented. The effect of cleaning procedure on the degree of permeability restoration by the fouled membrane was studied. The results demonstrated that a combination of sodium hydroxide, phosphoric acid and sodium hypochlorite as a disinfectant could be successfully used to achieve an optimum recovery of the membrane properties.

Opis:
Purpose: Presenting how blood pressure cuffs are cleaned by nurses and which disinfectant agents are used in cleaning the cuffs will allow conducting detailed studies that can establish a standard procedure for cuff cleaning. However, there is no study on the views of nurses and application procedures regarding the cleaning of blood pressure cuffs. Therefore, this study aimed to determine nurses' attitudes regarding cleaning the blood pressure cuffs in Turkey. Materials and methods: The study sample was composed of nurses working in Turkey who were invited and agreed to participate in the study from February to March 2021. This study was completed with 286 nurses with 90% power. Research data were collected online via Google Forms. Results: In the study, 64.3% of the nurses stated that the cleaning staff should be responsible for cleaning the cuffs. 29.4% reported that the cuffs were cleaned several times a month, and 20.3% stated that cuffs were cleaned only when they were infected. 52.1% reported that alcohol was used for cleaning the cuffs. Conclusions: Nurses agreed on the necessity of cuff cleaning and that the cuffs could be a source of infection when they were not cleaned. Since nurses have an important role in infection control, they should play an active role in cuff cleaning and receive training on this issue.

This paper gives a brief overview of the challenges wafer cleaning technology is facing in the light of advanced silicon technology moving in the direction of non-planar device structures and the need for modified cleans for semiconductors other than silicon. In the former case, the key issue is related to cleaning and conditioning of vertical surfaces in next generation CMOS gate structure as well as deep 3D geometries in MEMS devices. In the latter, an accelerated pace at which semiconductors other than silicon are being introduced into the mainstream manufacturing calls for the development of material specific wafer cleaning technologies. Examples of the problems related to each challenge are considered.

Opis:
Consideration of ultrasonic cleaning as a process with distributed parameters enables reduction of power consumption. This approach is based on establishment of control over the process depending on fixed values of ultrasonic responses in set points. The initial intensity of radiators is determined using a three-dimensional (3D) interval type-2 fuzzy logic controller essentially created for processes with distributed parameters, as well as complex expert evaluation of the input data. The interval membership functions for the input and output data consider the space heterogeneity of ultrasonic cleaning. A rule base is formed, which is 2D and not dependent upon the number of input and output parameters. A model illustrating ultrasonic cleaning with a 3D interval type-2 fuzzy logic controller is designed. Comparative analysis of the output parameters of the proposed model and the traditional method indicates an increase in the energy efficiency by 41.17% due to application of only those ultrasonic radiators that are located next to the contamination.

Opis:
Objectives: Cleaning products are considered less hazardous than those used in other sectors. Suppliers and distributors are less conscientious when it comes to informing users on health risks. The aim of the study was to elaborate on the usefulness and clarity of information in the safety data sheets (SDS) for cleaning products, and considering if the use of these SDSs can be seen as a risk factor towards occupational exposure to hazardous chemicals in the sector. Material and Methods: Safety data sheets were selected based on the risk level of the product assigned in an industrial sector scheme. 320 SDSs for cleaning products were reviewed. Constituent components found in the products over a given threshold were listed and available information thereof used to assess the perceived non-hazard consideration of the chemicals. Results: The contents of the SDSs was generic and mostly incomplete. Safety measures and health information lacked sufficient specificity despite varying compositions and concentrations of components. There is generally incompatibility between mentioned sections on the suggested non-hazardous nature of the products and health effects. Not all substances used in these products have harmonized classifications, which makes them open to various classification of the products and the suggested safety measures. This results in different companies classifying similar products differently. Risk management measures and suggested personal protective equipment (PPEs) are given haphazardly. Physical properties relevant to risk assessment are not included. Conclusions: The safety data sheets are ambiguous, and they lack relevant and important information. Inadequate information and risk assessment concerning the products can lead to workers being exposed to hazardous chemicals. Underestimation of the hazard contribution of the components of the products and the insufficient, non-objective mention of appropriate control and protective measures are the major contributing elements. There is a need to test the products in order to establish health effects and product specific safety measures.
