Analisis Potensi Pemanfaatan Limbah Cair Industri Ransum Makanan Hewan PT. X di Provinsi Jawa Timur

Analysis of the Potential Utilization of Liquid Waste from PT. X's Animal Feed Industry in East Java Province

Abstract

PT. X merupakan industri yang bergerak di bidang ransum makanan hewan. Dalam kegiatan operasionalnya PT. X menghasilkan air limbah domestik dan air limbah industri. Air limbah industri akan diolah menggunakan unit pre-treatment sebelum diolah bersama di IPAL domestik bersama air limbah domestik. Limbah cair yang dihasilkan PT. X sebanyak 11,18 m3/hari dan akan dimanfaatkan untuk penyiraman RTH sebesar 10,68 m3/hari serta pencucian kendaraan operasional sebesar 0,5 m3/hari, sehingga efisiensi pemanfaatan sebesar 100%. Limbah cair yang dihasilkan mengandung parameter pencemar berupa BOD5, COD, TSS, NH3-N, Minyak Lemak, Total Coliform, TDS, Fenol, (Cu), dan (Fe), sehingga diperlukan pengolahan melalui IPAL domestik agar memenuhi baku mutu yang dipersyaratkan. Teknologi yang digunakan pada IPAL PT. X yaitu Anaerobic Baffled Reactor (ABR). Setelah dilakukan pengolahan, effluent yang dihasilkan dimanfaatkan untuk penyiraman RTH dengan dosis penyiraman sebanyak 0,35 L/m2/hari.

PT. X is a company engaged in the animal feed industry. In its operations, PT. X generates both domestic and industrial wastewater. The industrial wastewater undergoes pre-treatment before being combined with domestic wastewater for treatment in the domestic wastewater treatment plant (WWTP). The total liquid waste produced by PT. X amounts to 11.18 m³/day, which is fully utilized for irrigation of green open spaces (10.68 m³/day) and washing operational vehicles (0.5 m³/day), achieving 100% utilization efficiency. The wastewater contains pollutant parameters including BOD5, COD, TSS, NH3-N, oils and fats, total coliform, TDS, phenol, copper (Cu), and iron (Fe), necessitating treatment through the domestic WWTP to meet the required quality standards. The technology employed in PT. X’s WWTP is the Anaerobic Baffled Reactor (ABR). After treatment, the effluent is used for irrigation of green open spaces at a dosage of 0.35 L/m²/day.
