Analisa Limbah Cair Pada Sistem Pengolahan Industri Tepung Tapioka

Sari

In the era of the revolution industry 4.0 the process production of goods became easier with a faster time. One of the applications of the industrial revolution is in the tapioca industry.  Beside producing tapioca flour, it also produde waste which is one of the problem. The waste can cause environmental damage if it is not treated first. The purpose of this studi is to analyzed liquid waste in the processing system of tapioca flour industry. Liquid waste tapioca flour before dumped into the environmsent done processing first through some stages namely through the acidification, the anaerobic primary, the anaerobic secondary, the aerobic, and the precipitation. This waste treatment aims to reduce the content of compounds that exist within liquid waste. After going through some this stages done testing the content of BOD, COD, TSS, and pH on the liquid waste and compared with a quality standards waste safe for dumped into the environment. Based on the result of research is known that the liquid waste in the industry tapioca after done processing contains chemicals meet a quality standards based on the minister of environment the republic of Indonesia number 5, 2014.
