<b>Abstrak</b> <p align=\"justify\">The development of textile industries more and more rise that goes along with the increasing of population growth. The rapid growth of industry cause to environment problems, especially textile industry. This problem have been this research background which it is used to investigate the influence of operation parameter, the modeling and the examining of the model toward the ability of microfiltration process in waste water treatment of dyeing process. The arranged model is a mathematics model which represent the mass transfer. The observed research is the influence of feed concentration as functions of the time. <p align=\"justify\"><br /> This research uses textile waste water with COD 917 - 1265 mg/L. The feed tank is made of stainless steel with volume of feed tank was 50 L. The main aid used to this research is microfiltration membrane hollow fiber which made of polyether sulfone material . It has 0,2 ;ma pore size, 0,2 mm thickness per fiber, 11n length per fiber, membrane area was 1 m² and it is made by X -flow By, Netherlands The feed solution is put into the feed tank, pumped pass through the membrane. The fraction that has already passed through the membrane leaves the process (for continuous operation) or recycled to the feed tank (batch operation). Then the fraction that penetrate the membrane (permeate) is analyzed its contents. The parameters measured toward the permeate quality are colour, TS, TSS, Fe, hardness and COD concentration. Continuous operation shows flux result and selection which similar with batch operation. The main assumptions built to solve the equation are considered completely mixed, fixed physical character of fluid, fixed flow debit, concentration input given once during simulation. The equation is numerically solved by Euler Explicit method. <p align=\"justify\"><br /> This researches result had shown that: (1) The elimination level of colour 93,6 %; COD 85,94%, hardness 33,17 - 42,6%, TS 50 - 56% TSS up to 100% and Fe 88 - 100%. All there data had shown that the elimination efficiency of the process is greater than conventional process. (2) The model which is built and simulated for 25 hours could be applied to estimate the concentration. (3) From numerical simulation results, the correlation of colour, hardness, COD, TS dan Fe concentration give 0,789; 0,63; 0,75; 0,91 and 0,54.
