Hi i work at PCB shop in New Zealand and i am looking at waste treatment options and water savings for the whole factory. By now i am totally confused :-), there are so many options and possibilities to create a total waste treatment system. i would like to hear what other people are doing in way of water reduction and waste treament. We are looking at a number of different things such as water cooler for recirculation of cooling water, different plating cells and RO/ion exchange systems for recirculation of rinse waters. It is just very hard to determine what is the best way of doing it so i would love to talk to all of you guys who are already involved in this to figure out what direction we should be heading. There must be a lot of peopleout there doing a lot more than we are here in New Zealand. Our environmental laws are not that strict yet as in other parts of the world but they are definatly on the way and we want to be ahead of the requirements. So please guys help me out here with some ideas and what you are doing. I'll be most grateful. Many kind regards Marie Holmgard ############################################################## TechNet Mail List provided as a free service by IPC using LISTSERV 1.8c ############################################################## To subscribe/unsubscribe, send a message to [log in to unmask] with following text in the body: To subscribe: SUBSCRIBE TECHNET <your full name> To unsubscribe: SIGNOFF TECHNET ############################################################## Please visit IPC web site (http://www.ipc.org/html/forum.htm) for additional information.
