Removal of Oily Wastewater Using Chitosan-filled Filter Media

The aim of this research is to evaluate the feasibility of the fibrous media for removal of total suspended solid and oil grease from palm oil mill effluent (POME). Wet lay-up method was adopted for filter fabrication where empty fruit bunches (EFB) were matted together with chitosan in non-woven manner. Chitosan-filled filter media were tested for their ability to reduce Total Suspended Solids (TSS) and Oil & Grease (O&G) from palm oil mill effluent. Filtration process results indicated that chitosan-filled filter media filtration only removed up to 28.14% of TSS and 29.86% of O&G.

Palm Oil Mill

The purpose of current study was to examine the ability of electrocoagulation in decreasing chemical oxygen demand (COD) and total suspended solid (TSS) constituted in palm oil mill effluent. Bench-scale batch reactor containing two aluminum or steel plates (10 cm width × 30 cm height with 0.1 cm thickness) serving as electrodes with the interval distance of 3 cm was set up. The wastewater with COD concentration of 68,425 mg L-1 was treated in the reactor under the varied direct currents (0.3-1.3 A) and contact time (30-120 min). Sodium chloride was added to the wastewater to obtain the final concentration of 2 g L-1 (conductivity of 10 ms) prior to being fed into the reactor. The results showed that higher treatment efficiency when the aluminum was used as electrodes compared to the steel. COD removal efficiency was directly proportional to the contact time. The maximum COD and TSS removal observed at 1.3 A current input and 60 min contact time are 74.1 and 77.0%, respectively.

Palm Oil Mill

Palm oil processing is a multi-stage operation which generates large amount of palm oil mill effluent (POME). Due to its potential to cause environmental pollution, POME must be treated prior to discharge. Electrocoagulation (EC), adsorption (AD), combined EC and AD, and EC integrated with AD have demonstrated great potential to remove various organic and inorganic pollutants from wastewater. Up to date, no study has been found on POME treatment using EC-AD hybrid process. Therefore, this study aims to investigate the feasibility of applying EC-AD hybrid process as an alternative treatment for POME. The EC-AD hybrid process achieved higher removal of total suspended solid (TSS), chemical oxygen demand (COD) and colour as compared to EC and AD stand-alone processes. The EC-AD hybrid process reduced 79% of TSS, 44% of COD and 89% of colour from POME. The adsorption kinetics of TSS, COD and colour were best interpreted using pseudo-second-order model, which indicated that the adsorption rate was mainly controlled by chemisorption. Overall, the EC-AD hybrid process could be recommended as an alternative treatment for POME.

Batch Treatment

Batch treatment of palm oil mill effluent (POME) was investigated using physical, chemical and biological methods. Physiochemical parameters such as pH, sulphate (SO42-), total dissolved solids (TDS), total suspended solid (TSS), chloride ion (Cl-), biological oxygen demand (BOD), chemical oxygen (COD) and metals (Fe2+, Zn2+, Ca2+ and Mg2+) concentrations were determined using American Public Health Association (APHA) methods. The results revealed that significant treatment was achieved at each stage. However, the biological method proved to be the best with percentage reductions of 45.6%, 97.6%, 71,0%, 50.1%, 80.4%, 93.8%, 72.0%, 85.4%, 93.2%, 77.7%, 86.2% and 85.7% for pH, SO42-, TS, TDS, TSS, Cl-, BOD, COD, Fe2+, Zn2+, Ca2+ and Mg2+ respectively. The concentrations after treatment were in conformity with the minimum acceptable standard of FEPA and WHO.
