PERENCANAAN PENGOLAHAN AIR LIMBAH SISTEM TERPUSAT (STUDI KASUS DI PERUMAHAN PT. PERTAMINA UNIT PELAYANAN III PLAJU – SUMATERA SELATAN)
Abstrak: The level of
pollution is the same comparable to the rate of population growth in the
region. The more densely populated an area, the potential of the damaged
environment will be even greater. This addition led to increased quantity and
quality of wastewater generated, so the installation of better waste water treatment
is necessary because the current management isn’t up to standard. To reduce the
impact of pollution, a plan to build a wastewater treatment facilities in the
domestic communal housing of PT. Pertamina UP III Plaju is like Wastewater
Treatment Plant (WWTP).This study aims to calculate (1) the next 10 years
population projection, (2) the total volume of waste water generated, (3) the
dimensions of the channel carrier and wells collector, and (4) the dimensions
planned of the IPAL unit and its area of land required for construction of
the plant. The methods used for collecting the data are field surveys,
documentation and review of the literature relating to the subject matter. The
results of the calculation of wastewater discharge to the next 10 years is
equal to 6.574 L / sec. Pipes used as main pipe is a kind of PVC pipe with a
diameter of 216mm (8 ") with the roughness Manning coefficient of 0.009.
Based on the selection criteria for the wastewater treatment process in
accordance with the conditions of the location, the time for planning is to be
used with aerobic – anaerobic waste water biofilter. The dimensions of the main
processing of waste water building is 8 meters wide with a depth of 2 m below
the ground surface and 1.5 m above the ground. The length of the initial
settling basin is 15 m, 14 m anaerobic biofilter tank, 12 m aerobic biofilter
tank, and 15 m final settling basin. Equalization tank made into 2 tanks with
each 10 m wide and 16 m long.The land required to build the installation is
approximately 70 m x 20 m square.
