Sulphurnet was founded after a simple observation that the world has changed. So many new developments were available, and the industry simply did not keep up with these ideas. The design of the process was decades-old. We concluded that the old technology was outdated and we had to rethink the best way to introduce these new solutions to our customers. Most of our clients were using old, so called “proven” technology, and we needed to convince them that things could be done differently. We decided to combine the latest technology and all the tools that are needed to deliver a complete filtration process with turnkey service to make this transition painless. www.sulphurnet.com
