“Penurunan Kadar Besi Dengan Variasi Luas Trap Cascade Aerator Dan Debit Pada Air Gambut”

---

ABSTRACT
Fe content is a metal that is quite high in peat water. One technology that
can be applied to remove Fe content is aeration. Aeration is the process of
adding oxygen to water so that it can cause Fe oxidation reaction which will then
cause Fe(OH)3 deposition. This study aims to determine the ability of the cascade
aerator to remove Fe content in peat water with discharge variations of 4, 4,5,
and 5 l/min with a variation of the trap area of 1,8 m2 and 2 m2. Also calculated is
the value of the gas transfer coefficient (KLa) in the aeration process using a
cascade aerator. Fe content before aeration was 1,22 mg/l. The results showed
that the highest efficiency of removal of Fe content occurred at a discharge of 5
l/minute at a trap area of 2 m2 with an efficiency of 81,16%. The highest gas
transfer coefficient value was obtained at a discharge of 5 l/minute on a 2 m2 trap
area of 0,111/minute. The research results obtained have met the clean water
quality standards PERMENKES RI No. 32 years 2017.
Keywords: Cascade Aerator, Iron (Fe), Discharge, Trap Area, The Coefficient Of
Gas Transfer (KLa).
