A new sales opportunity, along with the improved repeatability of K-Patents PR-23 Refractometer, can be found in the in-line safety monitoring of Total Organic Carbon (TOC), e.g. alcohols, proteins, sugars, fats, etc. in various wastewater streams in the corn sweetener and beer brewing industries.
As these streams typically contain high levels of TOC (up to 10,000 PPM) the Refractive Index technique has proven very successful for this purpose.
The wastewater treatment plant needs to know the incoming TOC to keep the treatment process in proper operation and in regulatory compliance. An early alert of incoming excess TOC is very important, since excess organics in the discharge from the plant can incur fines and penalties. In severe cases the plant may even be closed.
TOC has traditionally been measured both on- and off-line. Conductivity and non-dispersive infrared (NDIR) are the two common detection methods used in on-line TOC analyzers. These analyzers are expensive to maintain and calibrate and there are frequent breakdowns in their operation. Laboratory off-line samples and testing are used to confirm the TOC analyzer readings. However, if the sampling frequency for the laboratory analysis is too small, potential TOC excursions can be missed.
K-Patents process refractometers provide reliable measurement for alarming of incoming dissolved solids (indication of high organics). Plant operators can take timely corrective actions to the treatment process. Ask the plant utility manager: "Do you monitor incoming TOCs?" "What issues are you having measuring the TOC?" "Would real-time TOC signal for alarming be helpful?" And please note that K-Patents refractometer can measure dissolved solids typically in 1,000 PPMs; not in PPBs.
