Abstract
Instalasi Pengolahan Air Minum (IPAM) adalah alat utama PDAM
Surya Sembada Kota Surabaya dalam melayani kebutuhan air bersih
para pelanggannya. Oleh karena itulah, IPAM harus bekerja secara
kontinyu 24 jam dengan kualitas dan kuantitas yang terjaga. Instalasi
PDAM Ngagel I dengan kapasitas 1300 l/dt.
Pada unit bangunan Instalasi PDAM Ngagel I ini, terdapat bagian
yang mempunyai peranan terhadap kualitas hasil produksi IPAM, yaitu
Clearator. Karena di Clearator ini proses penjernihan paling utama yang
terdiri dari flokulasi, koagulasi dan sedimentasi terjadi. Sedang pada unit
berikutnya yaitu filter lebih bersifat menyempurnakan dari sisa-sisa flok
kotoran yang belum terendapkan di Clearator.
Dari hasil evaluasi didapatkan data-data yaitu: Pada unit Clearator
parameter kinerja OFR (Over Flow Rate) belum memenuhi kriteria
desain yaitu 17.78 m3/m2/hari, Kinerja waktu detensi juga belum
memenuhi kriteria desain yaitu 50.27 menit, Gradien kecepatan
flokulator pada kompartemen I belum memenuhi kriteria desain yaitu
642.49 l/detik, Kompartemen II, III, kompartemen upflow memenuhi
kriteria desain yaitu 81.75/detik, 65.49 l/detik, dan 9.85/detik, pada
bilangan reynold belum memenuhi kriteria desain yaitu Nre= 218.83,
pada solid loading rate juga belum memenuhi kriteria desain yaitu 5.78
m/jam. ========== Drinking Water Treatment Plant (WTP) is the main tool PDAM
Surya Sembada Surabaya in serving customers needs clean water.
Therefore, IPAM must work continuously 24 hours with the quality and
quantity are maintained. PDAM Ngagel I installation with a capacity of
1300 l/dt newly constructed and operated is one of them
Installation building unit PDAM Ngagel I have, there is a section that
has the most decisive role to the quality of production IPAM, namely
Clearator. Because in this Clearator ultimate purification process that
consists of flocculation, coagulation and sedimentation occurred. Being
the next unit that filters are more complete than the remnants of floc dirt
that has not been deposited in Clearator.
From the results of the evaluation of the data obtained, namely: At
Clearator unit performance parameters OFR (Over Flow Rate) do not
meet the design criteria is 17.78 m3/m2/day, detention time performance
is also not meet the design criteria is 50.27 minutes, flokulator velocity
gradient in the first compartment not meet the design criteria is 642.49
l/sec, compartment II, III, upflow compartment meets the design criteria,
namely 81.75/sec, 65.49 l/sec, and 9.85/sec, the Reynolds number not
meet the design criteria that NRE = 218.83, on solid loading rate is also
not meet the design criteria that is 5.78 m/h.
