Abstract
Meningkatnya usaha laundry di Kota Surabaya
menyebabkan peningkatan limbah cair yang dihasilkan. Hampir
semua limbah cair dari usaha laundry tersebut dibuang melalui
selokan atau tangki septik tanpa proses pengolahan terlebih
dahulu sehingga berpotensi menimbulkan pencemaran tanah dan
badan air di sekitarnya. Limbah cair usaha laundry memiliki nilai
TSS 560 mg/L dan surfaktan 186,4 mg/L yang melebihi baku
mutu mengikuti Peraturan Gubernur Jawa Timur No. 72 Tahun
2013 yakni 100 mg/L untuk TSS dan 10 mg/L untuk surfaktan.
Salah satu cara mereduksi kadar pencemar dalam limbah cair
adalah dengan menggunakan filtrasi membran. Zeolit dan kitosan
merupakan bahan yang sering digunakan sebagai bahan
membran karena memiliki kemampuan yang baik dalam dalam
membentuk film, pengolahan mudah dan ketersediaan yang
melimpah. Penelitian ini bertujuan untuk menganalisis pengaruh
penggunaan membran dari sintesis zeolit dan kitosan terhadap
nilai fluks, rejeksi kadar TSS dan surfaktan pada limbah cair
usaha laundry.
Proses filtrasi menggunakan aliran cross-flow karena
memerlukan biaya operasi yang lebih rendah. Variasi yang
dilakukan dalam penelitian ini yaitu perbandingan komposisi
massa zeolit dan kitosan 1:1; 2:1 dan 1:2 (Z1C1; Z2C1 dan
Z1C2) dengan total massa yang digunakan yaitu 15 g, serta
variasi tekanan 1,5 bar dan 2 bar. Sedangkan limbah yang
ii
digunakan yaitu limbah cair laundry dengan konsentrasi 100%
tanpa penambahan air suling atau pengenceran.
Dari penelitian diperoleh data perbandingan komposisi
zeolit dan kitosan optimum, nilai fluks dan nilai rejeksi membran.
Perbandingan komposisi membran yang terbaik yaitu
perbandingan zeolit dan kitosan 2:1 (Z2C1). Nilai fluks tertinggi
didapatkan dari membran Z1C1 tekanan 2 bar pada menit ke-10
yaitu 39,99 L/m2.jam. Sedangkan efisiensi removal TSS dan
surfaktan tertinggi masing-masing pada membran Z2C1 tekanan
2 bar pada menit ke-20 dan membran Z1C2 tekanan 1,5 bar pada
menit ke-60 yaitu 90,71% dan 97,67%. =========== The increasing number of laundry industries, has caused
the increase of wastewater generation. Nearly all wastewater
from the laundry busines is disposed of through a sewer or septic
tank without any advance processing, so that potentially caused
contamination of soil and water. Laundry wastewater has a
concentration of TSS 560 mg/L and surfactant 186,4 mg/L where
the levels exceed the quality standards in East Java Province of
100 mg/L for TSS and 10 mg/L for the surfactant. One method to
reduced the pollutant in wastewater was using membrane
filtration. Zeolite and chitosan were materials that have been often
used as membrane material because it have a good ability in the
film-forming, easily processing and availability of abundant. The
aim of this research is to analyze the effect of using membranes
synthesized from zeolite and chitosan for flux and removing
pollutants mainly for the parameter of TSS and surfactant in
laundry wastewater.
The filtration process used cross-flow method because it
required lower operating costs. Variations in this research were
the mass composition ratio of zeolite and chitosan 1: 1; 2: 1 and
1: 2 (Z1C1; Z2C1 and Z1C2) with a total mass used of 15 g, and
variations in pressure of 1,5 bar and 2 bar. Where as the
concentration of wastewater used in the process was 100%
without the addition of distilled water or dilution.
iv
The research data showed composition ratio of optimum
zeolite and chitosan, the membrane flux and rejection or removal
efficienciy. The optimum compotition ratio of zeolite and chitosan
was 2:1 (membrane Z2C1). The highest flux in membrane
filtration was membrane Z1C1 in pressure of 2 bar at 10th minute
that was 39,99 L/m2.jam. Where as the highest TSS and
surfactant removal efficiencies at Z2C1 membrane pressure of 2 bar at 20th minute and Z1C2 membrane pressure of 1,5 bar at 60th minute were 90,71% and 97,67% respectively.
