Nanofiltration processes are finding wide applications in several 'wet' industries, such as water/wastewater treatment, water re-use, textile industry, diary industry, food industry and the pulp and paper indsutries. Despite this, no definitive book exists which covers the principles of the techniques and their potential and actual applications.

'Nanofiltration: Principles and Applications' is edited by three well-known specialists from Australia, and contains chapters from top international authorities. The result is a comprehensive and up to date account which will be essential reading for membrane designers, manufacturers and end-users worldwide..

Description:
The aim of this paper is to analyze effect of operating conditions (duration, flow rate, temperature and transmembrane pressure) on the purity ratio, colour changes and turbidity changes of the permeates obtained by ultrafiltration (UF) and nanofiltration (NF) applied for the clarification and purification of sugar syrup solution. The analysis was based on the results of experiments performed in batch conditions, with 2 L of the initial syrup., on two types of the flat, cross-flow membranes: polyethersulfone for the UF process, and polyamide for the NF process. The plan of the experiments was in accordance with a full factorial design, and the 12-parameter polynomial proved adequate for data processing in all the examined cases. It was found that the response surfaces do not have extremes. However, the conclusions towards optimization of operating conditions, in most cases, were as follows: (1) process duration could be shortened, (2) flow rate should be kept at the lower boundary and (3) transmembrane pressure should be kept at the upper boundary of the investigated experimental space. Temperatures in the previous stages of the process mostly determined temperature at separation. The higher the temperature at separation, the lower the effect of separation. .

Description:
This paper investigates the utilisation of nanofiltration (NF), agitation (by pump or sonication), freezing and acetone extraction methods to purify paper machine o-water. The results were judged by regained pulp brightness and reduction of various components. In the NF experiments the brightness was almost totally regained. Also the reduction of most measured components like lignin and carbon were retained well by the membrane (PES). The metal ions (Si, Al, Mg, Na, K, Mn, Ca, Fe and Cu) were reduced in the permeate (retained by the membrane) to the level found in the clear filtrate. This indicated that the metal ions (Si, Al, Mg, Na, K, Mn, Ca, Fe and Cu) were not brightness-reducing components. The flux was rather low for a commercial application because the membrane was a low-flux membrane. The reduction of sugar, colour and lignin residuals was quite high (>80%), and it was considered that these were possibly brightness-reducing components. It was found that by treating the fines with acetone and then returning them to the original water, the colour was reduced to a high enough degree that approximately 50% of the brightness reduction was recovered. It was considered that coloured contaminants that were absorbed on the fines were removed or destroyed. The brightness recovery was >50% for both the TMP and PK4 o-water. The brightness recovery was greater using NF, but in that case so many substances were reduced in the permeate that it was difficult to determine which were the brightness-reducing substances. However, in the case of acetone washing, the only component that was reduced was the colour. For both o-water PK4 and TMP the colour was reduced by 50% and the brightness recovery was 50%, suggesting a direct correlation. Agitation of the water samples by the means of a pump and sonication showed no change in the water, which included no changes in the brightness. The same was also found for water samples that were frozen. These experiments also showed that temperature changes did not affect water composition. .

Description:
This work addresses the evaluation of nanofiltration (NF) and the minimization of NF membrane fouling in the treatment of surface water for drinking water production. The fouling characteristics of the natural organic matter (NOM) present in the surface water are dependent on the feed water composition and on the NF operating parameters. NF experiments were carried out in a DSS Lab-unit M20 with a membrane surface area of 0.216 m^2. Permeation experiments were performed both in total recirculation mode in order to optimize the operating conditions of pressure and recirculation flow rate and in concentration mode for design and optimization purposes. The concentration mode experiments were carried out at 15 bar and at a recirculation flow rate of 554 L/h. The water recovery rates (WRR) ranged up to 75%. A NF model was developed based on solute (NOM) and solvent differential mass balances and incorporating experimental data of the variation of permeation fluxes and total organic carbon (TOC) rejections with WRR. This model was used for the design of a NF plant with a permeate output of 100,000 m^3/d. The NF treatment cost was estimated to be @?0.214/m^3. .

Description:
Nanofiltration is an effective technique in improving the organic matter removal from coagulated surface water, but the process should also be economically feasible and environmentally sustainable when applied. Cost and environmental impact of nanofiltration installed after conventional surface water treatment were calculated and evaluated at different operating parameters in this study. The installation of nanofiltration after conventional surface water treatment would increase the cost of treated water in a minimum by 0.11 @?/m^3 in the studied case. The least cost was gained at the higher studied recovery (83%) at the driving pressure of 6 bar, where also the total environmental impact was well balanced. However, the installation of nanofiltration would increase the environmental impact of water treatment remarkably and improvements should be done to minimise these effects. The main ways to minimise the cost of nanofiltration were related to recovery of the process, energy consumption, membrane lifetime and membrane cleaning, whereas the environmental impact minimisation was mostly related to recovery of the process and energy consumption. .
