Peat soil - a cheap adsorbent and filtration medium for palm oil mill effluent treatment

Mohd. Asri Mohd. Nawi, . and Mohd. Nawi Ab. Rahman, . (1991) Peat soil - a cheap adsorbent and filtration medium for palm oil mill effluent treatment. In: Malaysian forestry and forest products research: proceedings of the conference. Forest Research Institute Malaysia, Kuala Lumpur, Malaysia, pp. 167-178. ISBN 967-9991-563

We explored the use of tropical peat specifically to treat palm oil mill effluent (POME). At present POME is treated via anaerobic pond system. Our study revealed that the treated water dispensed from some of these ponds are still below the standards stipulated. We designed a system to complement the ponding system for the treatment of secondary POME. Sapric peat from Gunung Jerai which was treated with H,SO, and used in fresh form works best as adsorbent. A semi-fluidized bed mode in conjunction with a sand-gravel bed filtration column was used. Parameters such as BOD, COD, TS, DS, ammoniacal nitrogen, oil and grease and colour were measured before and after treatment. In all, our system showed promise in improving the quality of the discharged effluent. Here, we also discuss the chemical composition of the peat, chemical modification and parameters investigated for its optimum effectiveness.

We designed a system to complement the ponding system for the treatment of secondary POME. Sapric peat from Gunung Jerai which was treated with H,SO, and used in fresh form works best as adsorbent. A semi-fluidized bed mode in conjunction with a sand-gravel bed filtration column was used. Parameters such as BOD, COD, TS, DS, ammoniacal nitrogen, oil and grease and colour were measured before and after treatment. In all, our system showed promise in improving the quality of the discharged effluent. Here, we also discuss the chemical composition of the peat, chemical modification and parameters investigated for its optimum effectiveness.
