“…The differences between reverse osmosis, ultrafiltration, nanofiltration, and microfiltration are outlined [5,6], highlighting the significance of pore size and selectivity to their use in desalination and, in some situations, water and wastewater treatment [7]. The article explains which membrane type is best for what, from large-scale desalination to eliminating micro-pollutants and pathogens [10]. The effectiveness of membrane filters is significantly influenced by material science (See Figure 2).…”

Granular filters and membrane filters, two essential filtration methods in environmental engineering, are thoroughly examined in this study. These techniques greatly aid air pollution control problems and water and wastewater treatment. The first section of the study outlines the basic ideas that underpin each filtration technique. The mechanical particle trapping mechanisms of granular filters, their wide range of applications in water treatment, and design factors, including media kinds and layers, are all examined. On the other hand, membrane filters are closely scrutinised because of their size exclusion principles, variety of types (from microfiltration to ultrafiltration), and vital function in industrial waste treatment and desalination processes. The study goes into additional detail about the maintenance, clogging, and financial ramifications that different filtering techniques must deal with. A comparison analysis provides insights into each method's applicability for various environmental engineering applications by illuminating its efficacy, affordability, and application specificity. The study's conclusion considers the potential for growth and current and upcoming technical developments in the filtration industry. This study lays the groundwork for forthcoming advancements and uses in the field of environmental engineering while also highlighting the significance of these filtering methods in modern ecological engineering.

“…A circulating granular filter system (CGBF-CLPs), using a dust/collector particles separator to regenerate the collector granules, was designed and investigated by Bai et al It was found that the fine particles partially returning to the granular bed filter reduced the bed voidage, as well as increased the dust collection efficiency. On the other hand, external field, such as electrostatic, acoustic and magnetic field, are also employed for enhancing the particle removal efficiency considering the fact that the field force increases the collision chance of particles. ,, A research on the use of a continuously counter-current moving bed filter with the electrostatic enhancement was carried out at 850 °C and 10 bar by Delft University of Technology …”

A compact dedust scheme coupling a cyclone with a built-in circulating granular bed filter (C-CGBF) for continuous hot gas cleanup is introduced. The effects of the operation parameters including the inlet dust concentrations, the inlet gas flow rates and the granules circulation fluxes on the separation performance of the C-CGBF are experimentally investigated using the FCC catalyst particles in a cold model setup. Experimental results reveal that stable/ high collection efficiency, generally higher than 98%, is achieved. A real-time monitoring method is developed for timely reflecting the instantaneous variation of the granules circulation flux, in which way a notable critical flux is observed as the transition from the fixed bed into the moving bed regime. The individual separation contributions of the cyclone and the built-in granular bed are both estimated. The particles collected by them are also analyzed respectively for comparing their size distributions.
