Penurunan Kekeruhan dan Bakteri Coliform pada Air Sungai Cibanten Menggunakan Karbon Aktif Tempurung Kelapa Sawit dan Zeolit Alam Bayah Teraktivasi

Abstract

Zeolit alam Bayah Activated (ZeOavd) and Carnel shell  activated carbon using pretretment with hidrogen peroxide (KATKS/H₂O₂) are porous materials for application multimedia filters in river water treatment. The purpose of this study to reduce turbidity and total coliform in the Cibanten River using ZeOavd and KATKS/H₂O₂. Sampel of Cibanten River flowing at 100 ml per minute into the KATKS/H₂O₂ filter tank and then flows into the ZeOavd material. Sampling was carried out 5 minutes after overflow for turbidity and total coliform analysis. The best results were checked until 5 to 120 minutes in range of 15 minute . The best results showed of  Cibanten River water contacted with 2 kg of KATKS/H₂O₂ and 2 kg of ZeOavd was able to reduce total coliform from 240 MPN/100 mL to 0 240 MPN/100 mL. In addition, it was able to reduce turbidity from 57.1 NTU to 1.60 NTU.
