The key demands on manufacturers in the modern-age markets globalisation are: (i) short development cycle, (ii) cost effectiveness, (iii) excellent product quality, and (iv) in-built product variability and upgradability. Development of new products under such dynamic market conditions necessitates an integrated approach to all stages of company operations, including product design, prototyping, productionising...
This paper presents efficient treatment methods for dairy wastewater using membrane techniques and applying the biological utilization of secondary wastes. The influence of ultrafiltration (UF) and both ultra- and nanofiltration (UF/NF) systems on the removal efficiency of the contaminants was determined. It has been found that the UF enables the removal of larger organic compounds, whose presence...
The impact strength tests of adhesive joints loaded for cleavage using a wedge-shaped impactor are generally described in the Polish Standard PN-EN ISO 11343. In order to conduct the tests, it is necessary to prepare bonded samples consisting of two specially formed elements. To form sample elements, it is necessary to take advantage of a special device, which is not adequately described in the standard...
One of the most effective ways of shaping the operating parameters of functional elements is the modification of the surface layer by modern surface engineering technologies. The most perspective directions in the development of surface engineering solutions are multilayer coatings. The appropriate selection of parameters of multi-layered structure such as thickness, chemical composition, microstructure,...
Closing technological cycles by means of reducing the amount of waste and its management is one of the main issues addressed in manufacturing companies. Low temperature heat is an example of technological waste which may take the form of hot flue gases, cooling liquids from industrial processes, or hot water from heating vents or operating installations. One of the methods of managing low temperature...
In the dynamic development work in the use of plant waste to produce biocarbons, the assumed sorption capacity resulting from the chemical structure of the surface determines the need to adapt the advanced spectral methods to test the quality of newly-manufactured materials. In this paper, the usefulness of X-ray energy dispersion spectroscopy (EDS), infrared spectrophotometry (FTIR), and Raman spectroscopy...
The paper presents a method for defect detection in tableware glass products using a structural backlight system. In the first part of the article, the designing of the imaging system is described. Furthermore a real-time system for generating pattern images is presented. Finally, laboratory tests carried out using the developed system and algorithms for image processing and analysis are described.
In the article, the authors present the results of erosion tests of five different material solutions of surface engineering, i.e. multilayer coatings type Cr/CrN/(CrN-Me1Me2N)multinano/(Me1Me2N-VN)multinano, where metals Me1 and Me2 were chosen from Al, Cr, Ti, Zr and Si. Multilayer coatings used for testing were deposited by the Arc Evaporation method. The research methods presented in the article...
This article describes a method for vision monitoring of the glass surface inside a glass furnace with its main advantages and limitations. It presents the structure of a vision monitoring system developed by the authors with a dedicated vision head and the operator’s stand. The elements of this monitoring system have been installed in a glass factory. The experimental research which has been conducted...
The article presents a heat exchanger with thermoelectric generators, which consists of two single sheet heat exchangers, between which thermoelectric generators are placed. The heat exchanger in question is used to convert waste heat energy into DC electricity. The construction of the heat exchanger is described in detail in the article, and the study of temperature distribution of both the high...
This study investigated the efficiency of synthetic dairy wastewater treatment using three commercial activated carbons (AC) originating from various raw materials and prepared with different granulations, such as powdered activated carbon and granular activated carbon from wood and granular activated carbon from coconut shell. The additional step after the treatment with AC was ion exchange using...
Businesses today are incredibly data rich, and dealing with large amount of data, so making some inferences and conclusions, depending on the organisation size and complexity of its processes, it has been a challenge, especially that the next disruptive phase in manufacturing, i.e. Industry 4.0 (I4.0) is already underway. Business Intelligence (BI) and Enterprise Resource Planning (ERP) have become...
