STP Tegal Gundil maximum capacity
Sebagaimana didetailkan di Bab 6.2.1, proses WSP eksisting di IPAL Tegal Gundil memadai untuk
mengolah limbah 2400 rumah tangga. Waktu retensi minimum yang direkomendasikan untuk sistem WSP
adalah 4 hari, untuk 2400 sambungan, waktu retensi di IPAL Tegal Gundil adalah 4 jam, sehingga
kapasitas pengolahan memadai untuk melayani rencana peningkatan zona pelayanan air limbah. Lihat
Tabel 6.5 untuk detail kalkulasi proses.

UASB reaktor IPAL Paledang
Kriteria desain dan desain reaktor UASB untuk tahun 2015 disajikan pada Tabel 6.6. Akan dibutuhkan 3
unit reaktor, berukuran panjang 21 meter, lebar 8 meter dan tinggi 5 meter. Sebagai alternatif, 2nam
reaktor fiberglas bertulang dapat juga digunakan. Masing-masing reaktor berukuran tinggi 5m dan diameter
10m. Unit ini dapat digunakan kembali untuk tujuan lain ketika IPAL Paledang tidak digunakan lagi saat
wilayah embrio sudah tersambung dengan pipa induk zona Pusat dan pengolahan air limbah dipusatkan di
IPAL Kayumanis.
