Abstract

PAM Ngagel III merupakan salah satu instalansi yang mempunyai air bersih di wilayah Surabaya. Sehingga penting untuk menjaga unit-unit pengolahannya agar tetap terjamin baik dari segi kualitas, kuantitas, dan kontinuitasnya. Pencucian filter merupakan suatu proses untuk menjaga kualitas air pada unit filter. Proses pencucian filter seluruhnya menggunakan sistem backwash dan sebagian surface wash. Hal ini mengakibatkan kebutuhan air untuk proses pencucian filter menjadi sangat fluktuatif. Berdasarkan permasalahan di atas dilakukan penelitian untuk mengetahui keefektifan waktu backwash pada waktu pencucian filter. Penelitian ini memvariasikan waktu pencucian mengikuti operasi yang ada di instalansi dengan parameter warna, kekeruhan dan oksigen terlarut. Variasi waktu dimasukkan ke perhitungan program dinamis dan diperoleh waktu optimal untuk backwash I = 9 menit, backwash II = 10 menit dan tanpa menggunakan surface wash. Kualitas air yang dihasilkan sudah sesuai dengan KepMenKes No. 907/MENKES/SK/VII/2002. Kesimpulan dari penelitian ini bahwa pencucian filter tanpa menggunakan sistem surface wash dapat menghemat kebutuhan air sebesar 1.447 m³/hari.

PAM Ngagel III is one of the installations which supplies fresh water in Surabaya. It is very important to maintain the units of installation to get fresh water in a good quality, quantity, and continuity. The wash of filter is one of processes to keep the good quality of water in filter. The wash of filter completely used the backwash and surface wash system. This resulted in the requirement of water in the wash process becoming very fluctuating. Based on the problems, a research was conducted to know the effectiveness of backwash time when washing the filter. This research has aimed to vary the time of filter wash to follow the unit of installation with the colour parameter, turbidity and dissolved oxygen. The time variation has been included into the resulting dynamic programming and obtained the maximum time for the backwash of I = 9 minutes, backwash II = 10 minutes and without using surface wash. The quality that was produced was according to Kepmenkes No. 907/MENKES/SK/VII/2002.The result shows that washing the filter without using surface wash system can economize the amount of water equal to 1,447 m³/day, which is allocated to process the filter wash.
