I am currently researching on UV applications for wastewater and main interest and questions being 1. what are the current practices of uv disinfection of wastewater in US and Canada for both municipal wastewater plants and industrial wastewater plants. 2. Regulatory guidelines w.r..t to uv disinfection requirements for wastewater in US and EUROPE , Canada and any data of each of the above regions. 3. Role of UV disinfection in wastewater considering it will play a significant role if wastewater is to be reused in downstream processess for recycling application. 4. Any plants in N. America, Europe or Asia adopting the Uv disinfection for wastewater for subsequent reuse application point of view. Thanks for your time and consideration Tejeet
