“…This low membrane fouling phenomenon for 1 and 2 kDa membranes was probably the result of a favorable relationship between CFV, pore size and rejected matter. As reported, [17] particles rejected by small pore size membranes could roll off under the forces generated by cross-flow, therefore, not causing membrane blockage. In the case of 500 kDa membrane, flux decline is most probably the result of particles migration through the pores, subsequent adsorption causing enhanced pore blockage or plugging.…”

“…Prior to further chemical cleaning, the normalized flux was measured with DW to determine chemically reversible fouling. [10] The CIP procedure was determined according to the literature [17,[21][22][23][24] and some preliminary trial-and-error tests with different chemical agents, concentrations and temperatures. After the CIP process, normalized flux with DW was observed again and any remaining membrane blockage was considered as chemically irreversible fouling.…”

“…This could be the consequence of the different adsorption and desorption mechanisms of the foulants based on different chemical compositions of the membrane active layer. [17] Table 5 represents the influence of temperature on fouling formation and removal for both membranes. It is obvious that the recovery of membrane flux was more effective at higher temperatures; therefore, temperature is an important operational tool when adopting a CIP strategy.…”

Textile wastewaters are rated as one of the most polluting in all industrial sectors, and membrane separation is the most promising technology for their treatment and reuse of auxiliary chemicals. This study evaluates the performance of three types of tubular ceramic ultrafiltration membranes differing by mean pore size (1, 2 and 500 kDa) treating textile mercerization wastewater from a textile mill at different operating conditions: cross-flow velocity (CFV) and temperature. Acceptable results were obtained with 1 kDa ceramic membrane, with rejection efficiencies 92% for suspended solids, 98% for turbidity, 98% for color and 53% for total organic carbon at 20°C and 3 m s −1 CFV. Highest fouling effect was observed for 500 kDa membrane and lowest CFV. According to the observed results, 1 kDa membrane could be used for the treatment of wastewater from the textile mercerization process in terms of permeate quality. ARTICLE HISTORY

“…Pre-treatment of spentwash with ceramic membranes prior to anaerobic digestion is reported to halve the COD from 36,000 to 18,000 mg/l (Chang et al, 1994). The total membrane area was 0.2 m 2 and the system was operated at a fluid velocity of 6.08 m/s and 0.5 bar transmembrane pressure.…”

LAPIŠOVÁ K., VLČEK R., KLOZOVÁ J., RYCHTERA M., MELZOCH K. (2006): Separation techniques for distillery stillage treatment. Czech J. Food Sci., 24: 261-267.The separation of stillage was tested by means of the pilot plant ARNO 600-BIO using three-channel ceramic membranes with the pore diameter range from microfiltration to ultrafiltration (1.4 µm-5 kDa). The permeate from the last membrane step was able to be recycled as technological water. The best results were achieved in the arrangement of series using 0.2 µm membrane as the first step supplemented by ultra-filtration membranes (50 kDa and 15 kDa), predominantly, where the reduction of the chemical oxygen demand (COD) extended 80%. With this process, we try to get some advantages over the conventional process in terms of eliminating both land and energy costs for the wastewater treatment process and improving the quality of the discharge water. The main goal in this study is to analyse different separation steps and conditions to find both the best separation options for the decrease of the final volume of distillery stillage, and the way how to make the bio ethanol production more profitable.
