PENJERNIHAN AIR LIMBAH BINATU (LAUNDRY) MENGGUNAKAN ALAT SEDERHANA

Abstract

ABSTRAK: Pesatnya pertumbuhan bisnis laundry di kota Palembang akan merusak lingkungan jika air limbah yang dihasilkan tidak dikelola dengan baik. Bahan aktif yang banyak terkandung di dalam limbah laundry mengakibatkan penurunan kualitas air. Sistem penyaringan berulang dan karbon aktif sangat efektif untuk mengurangi dampak pencemaran akibat air limbah . Pengolahan air limbah laundry bertujuan untuk mengetahui efektifitas penurunan konsentrasi Chemical Oxygen Demand (COD), tingkat kekeruhan air dan bau. Secara keseluruhan dari penyaringan berulang dapat mengurangi tingkat kekeruhan air sedangkan karbon aktif cenderung efisien dalam menurunkan kadar COD dan bau air limbah laundry.

Kata Kunci: Laundry, COD, kekeruhan, bau, karbon aktif.

ABSTRACT: The rapid growth of the laundry business in the city of Palembang will damage the environment if the wastewater produced is not well managed. Active ingredients in laundry waste cause a decrease in water quality. Repeated filtering systems and activated carbon very effectively reduce the impact of pollution due to wastewater. Laundry wastewater treatment aims to determine the effectiveness of decreasing the concentration of Chemical Oxygen Demand (COD), the level of water turbidity and odor. The results obtained from repeated filtering reduce the level of turbidity of water while activated carbon tends to be efficient in reducing the level of COD and the odor of laundry wastewater.

Key Word: Laundry wastewater, COD, turbidity, odor, activated carbon.
