The document describes the HaGun Treatment Plant, which is designed to capture dust and clean air from coal combustion. It works by arresting waste dust from furnaces using low-pressure wet steam in a steam room. The air is then further cleaned in a "raining room" that mimics the cleaning effects of rain. This results in clean air that can be safely released into the environment. The HaGun Treatment Plant aims to solve issues with previous electrostatic precipitator and wet scrubber methods that still left microdust and waste gases contaminating the air. It provides a more effective solution inspired by the air-cleaning effects of natural rain.

Abstract
HaGun TREATMENT PLANT as a dust catcher and the air cleaner coal combustion products. Waste dust from
the furnace was arrested using a low pessure wet steam at the steam room. Furthermore, in the clear air at room
raining. The results of this screening is clean air to be released into the environment.
Keywords: HaGun TREATMENT PLANT, steam room, raining room.
Abstrak
HaGun TREATMENT PLANT sebagai penangkap debu dan pembersih udara hasil pembakaran batubara.
Limbah debu dari furnace ditanggkap menggunakan wet steam low pessure at steam room. Selanjutnya udara di
bersihkan di raining room. Hasil dari penyaringan ini adalah udara bersih untuk dilepaskan ke lingkungan.
Kata Kunci: HaGun TREATMENT PLANT, steam room, raining room.

1. Pendahuluan
Batubara sebagai sumber energi utama di industri dan power plant. Hasil pembakaran batubara berupa debu dan
gas buang yang berpengaruh terhadap keseimbangan ekosistem.

Selama ini, untuk pengendalian debu dan limbah gas hasil pembakaran batubara dengan menggunakan
Electrostatic precipitator.
An electrostatic precipitator (ESP) is a highly efficient filtration device that removes fine particles, like dust and
smoke, from a flowing gas using the force of an induced electrostatic charge minimally impeding the flow of gases
through the unit.
In contrast to wet scrubbers which apply energy directly to the flowing fluid medium, an ESP applies energy only
to the particulate matter being collected and therefore is very efficient in its consumption of energy (in the form of
electricity). http://en.wikipedia.org/wiki/Electrostatic_precipitator
Wet scrubber. The term wet scrubber describes a variety of devices that remove pollutants from a furnace flue gas
or from other gas streams. In a wet scrubber, the polluted gas stream is brought into contact with the scrubbing liquid,
by spraying it with the liquid, by forcing it through a pool of liquid, or by some other contact method, so as to remove
the pollutants. http://en.wikipedia.org/wiki/Wet_scrubber
Electrostatic precipitator mempunyai kemampuan untuk menangkap debu, namun belum sampai untuk
pembersihan udara yang akan dikeluarkan ke lingkungan, karena debu micro dan gas limbah belum ditanggulanginya.
Akibat dari sistem Electrostatic precipitator, lingkungan di kawasan indistri masih terkontaminasi oleh debu micro
dan gas limbah.
Pengalaman di lingkungan, hujan mampu menjadi pembersih udara. Hal ini terjadi karena air hujan dan unsur
terkandung didalamnya mampu mengikat polutan yang ada di udara.
Bagaimanakah cara hujan membersihkan udara?

HaGun Treatment Plant dirancang meniru pola hujan dalam membersihkan udara. Sehingga udara dari proses
indistri akan dilepas ke lingkungan dalam kondisi bersih.
Berdasarkan ungkapan di latar belakang, maka dalam hal ini, perlu di lakukan penelitian tentang proses pembersihan
udara menggunakan HaGun Treatment Plant.
