Phosphorus removal using nanosized titanium dioxide

Purifics设计的单一集成平台系统可过滤、破坏和回收污染物，实现零液体排放。Purifics系统可以解决的特定水问题清单很广泛，包括金属，细菌，病毒，油，颗粒和其他化学物质，但磷，无论是正磷酸盐还是有机磷化合物，尚未被Purifics工程系统解决或测试。磷是一个主要的水处理问题，代表着Purifics潜在的增长销售市场。Purifics现有的工程产品包括Photo-Cat系统可以重新用于除磷。测试现有的Photo-Cat系统代表了利用二氧化钛纳米颗粒的拟议研究的第一阶段。就样品检测进度而言，将首先检测简单磷酸盐，然后 有机化合物和最终的真实的流出物。有机磷化合物不使用传统的水处理去除，这一系统将代表一个显着的改进，目前的做法。一旦现有的Photo-Cat系统配置经过测试，该项目将进入第二阶段，即研究新型纳米颗粒“配方”，其中将包括当前Photo-Cat系统中使用的默认二氧化钛以外的其他金属氧化物。这项研究将证明，如果纯化的照片猫系统，目前配置，或改进的版本，可以在除磷有用。

Purifics engineers single integrated platform systems that filter, destroy and recover contaminants with zero liquid discharge. The list of specific water issues that can be resolved with Purifics systems are extensive, including metals, bacteria, viruses, oil, particles and other chemicals but phosphorus, either as orthophosphate or as organic phosphorus compounds, has not yet been addressed or tested by Purifics engineered systems. Phosphorus is a major water treatment issue and represents a potential growing sales market for Purifics. Existing engineered products at Purifics including the Photo-Cat system could be re-purposed for phosphorus removal. Testing the existing Photo-Cat system represents Phase I of the proposed research utilizing titanium dioxide nanoparticles. In terms of a sample testing progression, simple phosphate will be tested first, then organic compounds and finally real effluent. Organic phosphorus compounds are not removed using conventional water treatment and this system would represent a dramatic improvement over current practices. Once existing Photo-Cat system configurations are tested the project will move to Phase II, the study of novel nanoparticle "recipes", which will include other metal oxides than the default titanium dioxide used in current Photo-Cat systems. This research will demonstrate if Purifics' Photo-Cat system, as currently configured, or an improved version, can be useful in phosphorus removal.
