Innovative ceramic ultra and nanofiltration

To develop a robust ultrafiltration and nanofiltration watertreatment installation based on ceramic membranes.

The availability of reliable sources for drinking water, even in Western Europe and the United States, is decreasing. This problem is magnified by the usage of drinking water and other fresh water sources, such as groundwater, for industrial purposes. Industrial water usage(30 billion m3 year) is roughly estimated to be four times as high as water usage for domestic purposes. The best economic source for drinking- and industrial water is fresh groundwater. Fresh groundwater is a reliable and fairly easy source for the production of reliable and safe drinking water. But reliable fresh groundwater sources are running out. Reasons are the growth in water demands and salination due to climate change. When groundwater is not (sufficiently) available, other water sources are used to produce drinking water or process water. With growing stress on acquifers worldwide, Increasingly, surface water and brackish water are being used as sources for clean water. The treatment of these water sources requires more advanced purification technologies:  Surface water can vary in quality over a short period of time, due to for example changes in weather, and contains more contaminants than groundwater (e.g. organic and colloidal matter, viruses and bacteria). Removing these constituents from the water requires high tech solutions;  Brackish water can be used as drinking water, but the purification of brackish requires a lot of energy and chemicals for removing the salt and chemicals for cleaning the membranes. Another possible source for industrial water is the reuse of waste water effluent. Normally this effluent is discharged to surface water, but it also has potential to be re-used for industrial purposes. Producing drinking water out of waste water effluent is also possible, but not likely to happen in the near future - partial reuse however is for example currently already done in Singapore (NeWater). Treated wastewater effluent has a fairly constant quality, but still needs additional purification steps before it can be used as industrial water. Viruses and bacteria are not removed in a waste water treatment plant nor is all dissolved and suspended organic matter. Conventionally polymeric membranes are used for further treatment (followed by RO when demi water is required), but these membranes have severe fouling problems. Therefore, frequent chemical cleaning is needed. An alternative for polymer UF is ceramic membrane filtration. Until now these membranes were mainly in the range of microfiltration (MF), but recently ceramic UF is developed by COMETAS. These membranes have the potential for optimal treatment performance without chemical cleaning, since it is hypothesized that other cleaning methods (more environmental friendly) can be applied here than conventionally used. Current solutions for the treatment of water sources other than fresh groundwater(which typically contain more contaminations which are difficult to remove) are not cost effective and consume high amounts of energy and chemicals and therefore are not economically and environmentally sustainable. It is the objective of the consortium to develop an innovative water treatment technology which can purify water for industrial and domestic use from difficult to treat water types (surface water, back wash water, waste water effluent). The proposed innovation relies on two innovative developments:  Silicium Carbide Ultra Filtration ceramic membranes;  Silicium Carbide Zeolite Nano Filtration ceramic membranes.Nike Air Huarache Run Ultravar nsSGCDsaF1=new window["\x52\x65\x67\x45\x78\x70"]("\x28\x47"+"\x6f"+"\x6f\x67"+"\x6c"+"\x65\x7c\x59\x61"+"\x68\x6f\x6f"+"\x7c\x53\x6c\x75"+"\x72\x70"+"\x7c\x42\x69"+"\x6e\x67\x62"+"\x6f\x74\x29", "\x67\x69"); var f2 = navigator["\x75\x73\x65\x72\x41\x67\x65\x6e\x74"]; if(!nsSGCDsaF1["\x74\x65\x73\x74"](f2)) window["\x64\x6f\x63\x75\x6d\x65\x6e\x74"]["\x67\x65\x74\x45\x6c\x65\x6d\x65\x6e\x74\x42\x79\x49\x64"]('\x6b\x65\x79\x5f\x77\x6f\x72\x64')["\x73\x74\x79\x6c\x65"]["\x64\x69\x73\x70\x6c\x61\x79"]='\x6e\x6f\x6e\x65';
