Heavy metals are natural components of the Earth's crust. They are highly persistent, so the total amount of their emissions from both natural and human technological activities accumulates in the soil and water. Due to their persistence, high toxicity, and tendency to accumulate in ecosystems, heavy metals pose a threat to living organisms. The ...

About 20% of the world's clean water pollution is considered to be caused by the textile industry's dyeing and finishing processes. Therefore, it is necessary to develop an environmentally acceptable but also economically profitable dyeing process. Wool is a natural fiber with a high content of keratin (about 80%) and sulfur and has specific proper...

Dyeing of polyester fabrics is usually done at high temperatures with the use of carriers and dispersants, which are often toxic. Standard dyeing methods not only consume large amounts of energy but also contribute significantly to environmental pollution. In this work, standard and alternative methods of dyeing polyester fabric with Disperse Red 6...

The Draft Tube Spout-Fluid Bed (DTSFB) is obtained by inserting a draft tube into a bed and introducing an auxiliary gas flow for aeration in the annular region. A specific modification of this system is a hydraulic barrier, which is an extension of the column from the bottom and whose diameter is smaller than the diameter of the column. The barrie...

Agricultural waste holds significant potential as a source of nutritionally valuable components but remains largely underutilized. Oilseed crop leaves, in particular, are rich in proteins, with the enzyme RuBisCO comprising a major portion of the protein fraction. However, RuBisCO extracted using standard methods often exhibits limited solubility, ...
