What Is Scrubber And How It Works To Prevent Air Pollution

YOGYAKARTA - An industry that does not install a scrub as an air pollution control tool will receive strict sanctions from the government. President Jokowi conveyed the warning of the obligation to install the scrub firmly. So what is a scrub and how does it work to reduce air pollution?

Scrubber is an exhaust air system that functions as an air pollution controller. The way the scrub works is to clean the exhaust gas before it is transmitted into the atmosphere.

The working principle of the scrub is to smoke air/vapor using a blower (from connected equipment), use a pipe (dutching), then air is sprayed with water. The air from the scrub will be released into the neighborhood by train after filtered using the High Efficiency Particulate Air (HEPA) filter.

The use of scrubs can help industry owners to clean up gas waste which is a threat to cleanliness and environmental conservation. This is because pollution from factories is very dangerous for health and disrupts the comfort of the surrounding community.

The existence of a scrub can neutralize pollution resulting from waste from the industry so as not to pollute the environment. This technology can also be used to control gas emissions, which are currently increasingly occurring.

Here are some types of scrubs that have different characteristics and functions:

Dry scrub serves to prevent acid rain by cleaning acid gas through the help of dry substances such as hydrogen sulfide. The way dry scrub works is by spraying dry substances on the drain flow.

Wet scrub is almost the same as dry scrub, but uses liquid/liquid to clean pollutants. Fluids that are often used in water wet scrubs.

Scrubber ventures are used to clean up dust, solid, aerosol, and steam particles in industrial exhaust gases. This Scrubber is the same as a wet scrub, namely using water in the process of cleaning pollutants.

Scrubber cyclone is used to clean particles on the gas without using a filter through vortex splitting. This Scrubber combines motion and gravity to separate fluid drops from the gas flow.

The technical provisions for using the scrub have been regulated in the Minister of Environment and Forestry Regulation Number 5 of 2021 concerning Technical Issuance Procedures and Operational Feasibility Letter for Environmental Pollution Control.

President Jokowi warned industries that have yet to install a scrub. This policy is implemented as an effort to improve air quality in Jakarta and its surroundings.

"Sanctions are certain and can be closed. Yesterday at the meeting it was conveyed, if you don't want to repair it, don't install a scrub, be firm for this, because the health price we have to pay is very expensive," said Jokowi during a visit at SMKN Central Java, Semarang, on Wednesday (30/8).

Jokowi said that handling air pollution in the capital needs to be done together from all elements. Starting from priority use of public transportation to planting trees.

The government has also implemented programs or steps to deal with air pollution, namely by operating weather modification technology, vehicle emission control, and supervision of the industry and PLTU.

Demikianlah review tentang apa itu scrubber dan cara kerjanya. Presiden Jokowi dengan tegas mengingatkan kepada para pemilik industri agar memasang skubber untuk mencegah penghinaan udara. Industri atau pabrik yang tidak menerapkan scrubber terancam bisa dijatuhi sanksi keras hingga ditutup.
