Rumah Potong Hewan (RPH) Ternak Sapi Kota Pontianak berada di dekat Sungai Kapuas dan sudah dilengkapi dengan Instalasi Pengolahan Air Limbah (IPAL), namun sampai saat ini masih menimbulkan pencemaran terhadap lingkungan sekitarnya. Untuk itu perlu dikaji dan dievaluasi sistem pengelolaan limbah cair yang dilakukan pada IPAL RPH Ternak Sapi Kota Pontianak saat ini, meliputi tingkat efisiensi pada tiap-tiap unit pengolahan limbah cair, waktu tinggal, dan debit air limbah RPH serta dicari langkah-langkah yang diperlukan untuk mengarah pada sistem pengelolaan limbah cair RPH yang memenuhi standar mutu buangan yang sesuai dengan persyaratan yang ditetapkan oleh pemerintah. Evaluasi kinerja berdasarkan efisiensi, waktu tinggal, dan debit limbah cair. Penelitian dilakukan dengan cara mengambil sampel limbah cair pada tiap-tiap lokasi titik sampel yang telah ditentukan. Sampel dilakukan pengujian parameter di laboratorium berupa BOD, COD, TSS, Suhu dan pH. Hasil penelitian menunjukkan bahwa bak pengendapan awal dan bak aerasi kurang memadai karena waktu tinggalnya yang kurang dari standar, dan dimensi bak tidak sesuai dengan debit limbah yang dihasilkan. Sedangkan bak sedimentasi dan bak penampungan akhir sudah memadai, namun perlu ada perbaikan pada dasar bak sedimentasi. Efisiensi total unit pengolahan limbah cair dari parameter setelah percobaan terjadi peningkatan yaitu parameter BOD dari 93,98% menjadi 96,1%, parameter COD dari 88,54% menjadi 90,73% dan parameter TSS dari 86,38% menjadi 90,77%.

The Cow Slaughterhouse in Pontianak is located near the Kapuas river and it has been completed with Wastewater Processing Installation (WPI), however this slaughterhouse still cause environmental pollution. Therefore, it is necessary to study and evaluate the wastewater processing system that has been done by WPI slaughterhouse in Pontianak at this moment, those are including the efficiency level in every wastewater processing unit, the detention time and wastewater discharge the slaughterhouse and it’s necessary also to find some steps that are needed to lead to the slaughterhouse wastewater that meet the effluent quality standard which appropriate with the requirements that was set by the government. The work evaluation based on the efficiency, detention time, and the waste water discharge. The research was conducted by taking the wastewater samples in each location that has been settled. From those samples the BOD, COD, TSS, temperature, and pH tests were conducted. The result of the research indicated that early sedimentation unit and aeration unit were not sufficient enough due to the lack of the detention time that far from standard, and the unit dimension was not approriate with the wastewater that had been produced. Meanwhile the sedimentation unit and the last reservoir unit had been approriate, but it would need repairment on the bottom of the sedimentation unit. The total efficient of wastewater unit process from the parameter had been increased after the experiments were conducted the BOD parameter had increased from 93,98% to 96%, the COD parameter had increased from 88,54% to 90,73%, and the TSS parameter had increased from 86,38% to 90,77%.
