Perancangan Pembangunan Instalasi Pengolahan Air Limbah pada Industri Frozen Food

Abstract

Air limbah industri frozen food mengandung bahan organik, padatan tersuspensi, minyak dan lemak, Amonia, serta deterjen sehingga berpotensi mencemari lingkungan jika tidak diolah optimal. Penelitian bertujuan merancang Instalasi Pengolahan Air Limbah (IPAL) 600 m3/hari dengan pengolahan pre-treatment, primary treatment, secondary treatment, hingga tertiary treatment. Hasil perencanaan menunjukkan sistem mampu menghasilkan efluen yang memenuhi baku mutu dengan konsentrasi COD 84 mg/L, BOD 56,1 mg/L, TSS 68,9 mg/L, minyak dan lemak 6,7 mg/L, Amonia 1,6 mg/L, dan MBAS 0,2 mg/L. Profil hidrolis dirancang melalui kombinasi gravitasi dan pompa sesuai kebutuhan elevasi. Sehingga IPAL yang dirancang dinilai efektif mengolah limbah terpadu hingga memenuhi baku mutu yang ditetapkan.

Wastewater from the frozen food industry contains organic matter, suspended solids, fats and oils, Ammonia, and detergents, which have the potential to pollute the environment if not treated optimally. This study aims to design a 600 m³/day Wastewater Treatment Plant (WWTP) incorporating pre-treatment, primary treatment, secondary treatment, and tertiary treatment processes. The design results show that the system is capable of producing effluent that meets quality standards with concentrations of COD 84 mg/L, BOD 56,1 mg/L, TSS 68,9 mg/L, oil and fat 6.7 mg/L, ammonia 1,6 mg/L, and MBAS 0.2 mg/L. The hydraulic profile was designed using a combination of gravity flow and pumps as required by the elevation. Consequently, the designed wastewater treatment plant is considered effective in treating integrated wastewater to meet the established quality standards
