“…An induction furnace is used in the remaining 11 iron foundries. PCDs used in iron foundries equipped with cupola furnaces include cyclones, venturi wet scrubbers, energy-e cient scrubbers such as spray towers or wet cap and dry cap collectors 4,9 . The PCDs used in iron foundries built into an induction furnace are the wet scrubber; the venturi wet scrubber, the bag lter, and the cartridge lter.…”

“…In this regard, a datasheet has been prepared to collect relevant data on the use of PCDs. By interviewing the managers of these iron foundries 4,9 , the data in this sheet is complete. In particular, the rejection rate, the GPS, and the pollutants before and after the implementation of the PCDs were entered into this sheet by questioning these o cials.…”

“…Thus, the contribution of the foundry industry is vital and crucial to many economies 6 . However, emissions from the foundry industry cause pollution [7][8][9] . These emissions are mineral dust and organic carbon emitted during the melting, sand casting, and cleaning of castings 4,10−13 .…”

“…These emissions are mineral dust and organic carbon emitted during the melting, sand casting, and cleaning of castings 4,10−13 . With the growing concern about environmental issues, the pollution problems caused by the foundry industry must be seriously and urgently investigated (Collina et al, 2017;Yang et al, 2020;Li et al, 2018;Yang and Zhang, 2018) Companies belonging to the foundry industry are more likely to come under public scrutiny, and therefore they are required to reduce emission levels by using pollution control Devices (PCDs). In this context, theorists and practitioners increasingly consider the need to install PCDs in the foundry industry (Mitchell, 2006;Rathi, 2003; Unnikrishnan and Hegde, 2007;Pham et al, 2019).…”

Right from the olden days, many products have been made according to foundry practices in order to generate prosperity in the societies in which they operate, while reaping these types of benefits through the operation of foundries. It is alarming that the emissions released by foundries affect human health. Therefore, foundries installed Pollution Control devices (PCDs), in accordance with this development; researchers examined the effectiveness of these PCDs in controlling emissions from foundries in different parts of the world. The emission control obtained by installing these PCDs is explained in this article based on the data gathered from the survey. The result of the study indicated that the cartridge filter built into the induction furnace achieves the best efficiency in controlling contamination from foundries. Interestingly, the operation of the cartridge filter has yet to be documented. Therefore, the construction, operation, the performance of the cartridge filter, and its efficiency in achieving contamination control in foundries are described. The article ends by emphasizing the need to conduct surveys in foundries in which a cartridge filter is installed. The results of this study will provide useful information on the use of cartridge filters in induction furnaces to reduce foundry emissions.

“…The input of mass entering into the scrubber unit method is 0.6 kg/sec. Generally, the wet scrubber is a pollution control device that reduces the power of the harmful gases coming out from the furnace [38][39][40] . The treated gas is passed into the chimney, and it was exhausted into the atmosphere.…”

When fine particles generated by the foundry industry are present in the atmosphere, they have an impact on the climate because of their influence on atmospheric radioactive phenomena. As a result of this scenario, there is a rising amount of legislation restricting the emission of pollutants from foundry industries and related businesses. In response to this situation, many researchers have concentrated on end-of-pipe technologies, one of which is the wet scrubber, which is a device that is primarily used in foundries to control pollution and is one of the devices that has been incorporated. The disadvantage of using this wet scrubber, on the other hand, is that it contributes to secondary pollution when it is used. In order to combat secondary pollution, a model of an enhanced wet scrubber system that incorporates a multi-sand filtering technology was developed. The performance of this redesigned wet scrubber system was evaluated with the use of computational fluid dynamics software. Because of the introduction of the filtration tank's computation, it was discovered that successful filtration was accomplished using sand filters, meaning that environmental chemicals and particles were totally filtered from 0.17 kg at the entrance to zero kg of particles at the outflow.
