In the WATER project the German Aerospace Center, and the Universidade Federal de Uberlândia, analyse the possibilities of treating paper mill effluents by solar photocatalysis for the paper mill of the Brazilian paper producer Votorantim Celulose e Papel, VCP, at Luiz Antônio, SP, Brazil. The degradation of the bio-polymer lignin is a vast problem in paper production. The tests have shown that treatment by the photocatalyst TiO2 and solar radiation is an ecological future oriented approach to solve this problem. The treatment of lignin containing process water by solar photocatalysis was optimised and the economics for solar treatment plants of different sizes was estimated to check the possibilities for implementing the technology in industrial processes.
在“水项目”中，德国航空航天中心和乌贝兰迪亚联邦大学针对巴西圣保罗州路易斯安东尼奥市的巴西纸制品生产商Votorantim Celulose e Papel（VCP）造纸厂，分析了利用太阳能光催化处理造纸厂废水的可能性。生物聚合物木质素的降解是造纸生产中的一个大问题。测试表明，使用光催化剂二氧化钛和太阳辐射进行处理是解决该问题的一种面向未来的生态方法。对含木质素工艺用水的太阳能光催化处理进行了优化，并估算了不同规模太阳能处理厂的经济性，以检验在工业生产过程中应用该技术的可能性。
