Purpose: The study aims to determine the effect of the backwash time on the parameters of the mesh self-washing filter. Theoretical framework: The duration of the backwash process can significantly affect the operation parameters of the mesh self-washing filter Method: During the study, experiments were carried out using a laboratory stand on which a mesh self-cleaning filter was installed. In the experiments, the filter operation parameters were measured at different values of the backwash time. Mathematical modelling methods were also used to determine the filtration efficiency. Results and conclusion: The results of the study showed that the backwash time significantly impacts the operation of the mesh self-washing filter. The optimal backwash time is from 20 to 30 seconds, while the percentage of filter clogging due to removing impurities during backwash is reduced by 20-25% compared to a shorter or longer backwash time. Research implications: These filters work on the principle of direct filtration when water passes through a sieve to remove suspended solids. The filter material is periodically cleaned by backwashing, which involves changing the direction of water flow through a sieve to remove accumulated solid particles. Originality/value: Water purification by suspended solids with a size of more than 100 microns is carried out by an amount of more than 99.5%. The filter provides reproducible cleaning quality, and the cleaning efficiency does not decrease from cycle to cycle.

Nanotechnology is an exciting area with great potential for use in biotechnology due to the far-reaching effects of nanoscale materials and their size-dependent characteristics. Silver and other metal nanoparticles have attracted a lot of attention lately because of the exceptional optical, electrical, and antimicrobial characteristics they possess. Silver nanoparticles (AgNPs) stand out due to their cost-effectiveness and abundant presence in the earth’s crust, making them a compelling subject for further exploration. The vital efficacy of silver nanoparticles in addressing environmental concerns is emphasized in this thorough overview that dives into their significance in environmental remediation. Leveraging the distinctive properties of AgNPs, such as their antibacterial and catalytic characteristics, innovative solutions for efficient treatment of pollutants are being developed. The review critically examines the transformative potential of silver nanoparticles, exploring their various applications and promising achievements in enhancing environmental remediation techniques. As environmental defenders, this study advocates for intensified investigation and application of silver nanoparticles. Furthermore, this review aims to assist future investigators in developing more cost-effective and efficient innovations involving AgNPs carrying nanoprobes. These nanoprobes have the potential to detect numerous groups of contaminants simultaneously, with a low limit of detection (LOD) and reliable reproducibility. The goal is to utilize these innovations for environmental remediation purposes.
