Abstract

Pengolahan air limbah industri crumb rubber dengan sistem lumpur aktif menghasilkan limbah berupa lumpur padat (Crumb Rubber Sludge) yang membutuhkan penanganan. Industri crumb rubber juga menghasilkan limbah padat lainnya berupa tatal karet yang tidak diolah kembali. Pada proses pengolahannya, selain industri crumb rubber yang menghasilkan limbah padat, terdapat industri kelapa sawit yang juga menghasilkan limbah padat berupa abu sawit. Salah satu cara untuk mengatasi dampak yang ditimbulkan oleh limbah padat indutri adalah dengan memanfaatkan limbah tersebut sebagai adsorben. Adsorben adalah suatu padatan yang memiliki fungsi untuk menyerap suatu komponen tertentu dari suatu larutan. Air limbah industri crumb rubber merupakan salah satu penyebab terjadinya pencemaran lingkungan. Paramater kunci air limbah industri crumb rubber salah satunya BOD (Biological Oxygen Demand), COD (Chemical Oxygen Demand) dan TSS (Total Suspended Solid). Apabila parameter tersebut nilainya melebihi baku mutu dan tidak dilakukan pengolahan, berpotensi menyebabkan pencemaran khususnya sungai sebagai badan air penerima. Hasil penelitian menunjukkan bahwa adsorben modifikasi Crumb Rubber Sludge dan tatal karet (CT) dapat dijadikan adsorben dengan daya serap yang tinggi, sehingga nilai persentase penyisihan berada diatas 80% dengan menggunakan variasi massa 0.5 gr, 1gr, dan 1,5 gr dengan waktu kontak 90 menit pada kecepatan pengadukan 120 rpm.

Abstract

Sewage sludge is a major by-product of the wastewater biological treatment process. Wastewater Treatment Plants at Palm Oil Mills (PKS) produce a lot of sewage sludge and until now it has not been optimally utilized. This study aims to examine the potential of PKS sewage sludge as an adsorbent for the removal of kromium (Cr) by the fixed bed column method. The study will also analyze the effect of recirculation on the reduction of kromium levels. The sludge was carbonized in a furnace at 300°C for 2 hours. Synthetic kromium wastewater was made at three concentrations of 2000 ppm, 3000 ppm, and 4000 ppm. The sludge adsorbent used was 100 grams which was filled into the fix bed column. Recirculation of kromium wastewater was performed 3 times. Adsorption isotherms were analyzed using Langmuir and Freundlich models. The results showed that the best removal without recirculation occurred at a kromium concentration of 3000 ppm with a removal efficiency of 48.07%. Furthermore, recirculation was carried out 3 times and resulted in varying removal values at the 1st, 2nd, and 3rd recirculation of 37.9%, 40.06% and 35.4%. The highest removal occurred in the second recirculation. The addition of recirculation led to a decrease in the sorption of chrome as the adsorbent had reached saturation point. This allows the release of kromium ions that have been adsorbed and causes the removal efficiency to decrease. A suitable adsorption isotherm model for sludge adsorbent is the Langmuir model, where the adsorption process occurs in a single layer and is homogeneous.
