Nitrate Generation Unit

STC, partnering with a group of renowned scientists, has developed a new and innovative way to combat an on-going problem the industry faces with biogenic hydrogen sulfide (H2S) resulting from sulfate reducing bacteria (SRB) activity in water.

These scientists with decades of experience in biological remediation of H2S, have patented a technology for the on-site generation of nitrates. STC's engineers worked with this technology to create the ON-SITE Nitrate Generation Unit, or "NGU," that can be used in a variety of industries and applications to mitigate H2S.

The NGU enables the customer the ability to continously generate nitrates near the point of injection (therefore, ON-SITE) to treat for H2S, thus removing the need to depend on a variety of third parties to supply the nitrate to the site. The NGU is a self contained system that only utilizes air, electricity and water to operate.  Low operarting and maintenance costs are also key highlights of the NGU.
