Abstract
PDAM adalah perusahaan yang melakukan pengolahan air baku untuk mendapatkan air bersih yang berkualitas dan aman. Air bersih yang berkualitas adalah air yang telah lulus uji dari Peraturan Menteri Kesehatan Republik Indonesia Nomor 736/Menkes/PER/VI/2010 dan Peraturan Menteri Kesehatan Republik Indonesia Nomor 492/Menkes/PER/IV/2010. Untuk mendapatkan air yang lulus uji perlu dilakukannya pengolahan air baku yang melalui unit kanal, prasedimentasi, koagulasi-flokulasi, clearator, clarifier dan filtrasi. Namun dikarenakan adanya sebuah kendala pada unit tersebut dapat menyebabkan unit pengolahan tidak berjalan secara optimal, meskipun tetap memenuhi persyaratan uji parameter. Salah satu unit di IPAM yang memiliki kendala yaitu unit clearator dan clarifier. Oleh karena itu, tujuan dari penelitian ini adalah menganalisis dan mengevaluasi kinerja unitclearator daan clarifier untuk mendapatkan faktor-faktor yang dapat meningkatkan kualitas air bersih. Metode yang digunakan pada penelitian ini yaitu dengan pengamatan hasil parameter kekeruhannya selama 3 minggu dalam bentuk persentase. Hasil yang didapatkan pada penelitian ini adalah terdapat beberapa faktor yang berdampak pada kinerja unit clarifier dan clearator, termasuk lamanya waktu pengurasan, kualitas flok yang kurang optimal, serta perubahan posisi tube settler.
PDAM is a company that treats raw water to obtain quality and safe clean water. Clean quality water is water that has passed the test of the Regulation of the Minister of Health of the Republic of Indonesia Number 736/Menkes/PER/VI/2010 and Regulation of the Minister of Health of the Republic of Indonesia Number 492/Menkes/PER/IV/2010. To get water that passes the test, it is necessary to treat raw water through the canal unit, prasedimentation, coagulation-flocculation, clearator, clarifier and filtration. However, due to an obstacle in the unit, it can cause the treatment unit to not run optimally, even though it still meets the parameter test requirements. One of the units in IPAM that has constraints is the clearator and clarifier unit. Therefore, the purpose of this study is to analyze and evaluate the performance of the clearator and clarifier units to obtain factors that can improve the quality of clean water. The method used in this study is to observe the results of the turbidity parameter for 3 weeks in percentage form. The results obtained in this study are that there are several factors that have an impact on the performance of the clarifier and clearator units, including the length of drain time, suboptimal floc quality, and changes in the position of the settler tube.
