Scrubber systems are a diverse group of devices that are used to control air pollution, and can be used to remove some PM and/or gases from industrial exhaust-gas streams. Traditionally, the term scrubber has referred to pollution control devices that use liquid to wash unwanted pollutants from a gas stream but, more recently with the evolution of gas cleaning operations, the term has also been used to describe systems that inject a dry reagent or slurry into a dirty exhaust stream to remove acid gases, such as carbon dioxide and hydrogen sulfide which elevate scrubbers to be one of the primary devices that control gaseous emissions, especially acid gases.

due to the complexity of this device, what is the alternative device for air pollution control if someone wants to used it in a mini-factory that emit harmful gases to the environment

This video shows how the electrostatic precipitator functions. Usually, they are large, industrial machines but I'm sure they could be made smaller. This guy seems to be thinking along the same line and has several videos where he experiments with small DIY air cleaners.

De-Sul by Green Framework Ltd

US-based start-up developed a system called De-Sul , which drastically reduces the Sulfur levels from the heavy fuel oil and made them compliant with new IMO regulations. Although it weighs 55 tons and is still an expensive system, it is much smaller and costs significantly less than its scrubber competitors, which makes it adequate for "smaller players" in the industry. It also opens new markets and revenue options by selling the collected slur. You can watch the presentation of the De-Sul system here (from 3:00) for more information.
