PEMISAHAN PADATAN TERSUSPENSI LIMBAH CAIR TAPIOKA DENGAN TEKNOLOGI MEMBRAN ULTRFILTRASI

Abstract

The large of material to suspended solids that implied in the volume of liquid waste cassava starch is burden the most weigt of manufacture and this matter become challege method phisis of manufacture. The research method was that is the solution to bait channelled the pump passed the membrane module. The pressure is set by using pressure regulator valve, and the taking of the sample was carried out after the operation achieved time that was determined. Retentat results treatment was recorded by his volume and was analysed by his COD content in the laboratory. Results of the test showed the separation capacity of suspended solid of 57% with selektifitas COD 70.49 %. Total solid matter that was contained to the potential for the raw material, that is 16.4 gr/litre the dry season and 5.69 gr/litre the rainy season, most protracted solid matter that was contained inside permeat could unload pollution and alleviated the burden of the processing of the following waste water. Could be concluded that the membrane ultrafiltrasi could separate suspended solid and his application efforts could function and be useful. Key word : cassafa liquid waste, separation suspended solids, the way of applicate it’s.
