Abstract

The status of indonesian palm oil industry in the world to be the fi rst one that built a modern palm oil industry. There is a trend of palm oil industry in the future time to be the dominan industry. On 2005 was increse to be 5.597.158 ha with CPO production about 12.451.000 ton which is spread in 20 provinces. The increasing of palm oil production give impact to solid and liquid waste potential. All the waste can be used as energy alternatif, beside that the potency of solid and liquid waste will give contribution to CO2 emission of global warming.Key words : palm oil.

Abstract

Soya bean sauce waste water is an high organic wastewater and has dark colour, therefore it is diffi cult to degrade it biologically. Base on as mentioned above, it is tried to process it with coagulation and fl okulation use Alumunium sulphate and PAC which is added to wastewater with several dosis variation of Alumunium sulphate: 100, 200, 300. 250, and PAC with dosis 50, 100, 150, 200 ppm. Experiment result shows the experiment which use a match Alumunium sulphate and PAC as coagulant could give a good quality of processing and suitable with the treshhold of wastewater. The application of fl okulan Aquaklir 240 could help the performance of coagulan that can be seen from the fl oc size form.Key words : fl occulation, coagulation.

Abstract

Seeding in Fixed Bed anaerobic reactor are infl uenced by several condition such as the growth rate total population of microbial, bacterial adaption to infl uent and the retention of biomass in reactor. The aim of this observation is to fi nd out the seeding and acclimation process in anaerobic process by using plastic as support material. Seeding and acclimatization process run smoothly can be seen from the increasing of infl uent or substrate and following by the increasing degradation of soluble COD, beside that the decreasing of VSS concentration indicates that microorganism are all ready fi x in support material, therefore reactor can be operated continuously and the acclimatization process can be stopped.Keywords : anaerobic seeding, acclimation anaerobic process
