K-Patents has released a new application note on Total Organic Carbon (TOC) Content Monitoring in Effluent. Excess organics, or Total Organic Carbon Content (TOC), e.g. alcohols, proteins, sugars, fats, etc. in various wastewater streams in the corn sweetener and beer brewing industries can incur fines and penalties. In severe cases the plant can even be closed.
As these effluent streams typically contain high levels of TOC (up to 10,000 PPM) the Refractive Index technique has proven to be a very successful measurement method for this purpose.
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 can be frequent breakdowns in their operation.
K-Patents Teflon Body Refractometer PR-23-M provides reliable measurement for alarming of incoming dissolved solids (indication of high organics). Wastewater treatment plant knows incoming TOC and can keep treatment process in proper operation and compliance.
