| The BioTector TOC Analyzer was originally developed to measure waste from a Wood Processing Plant discharging into the sea. The entire analyzer is therefore developed as an On-line TOC Measuring Device, which is capable of handling particulates of up to 2mm in size in a salt-water environment. |
All sample tubes and sample valves are sized with a minimum interior diameter of 3mm, this includes the bore of the ARS Valve which directs the sample into the reactor. In-line filters, screening devices or homogenising devices are not used.
The Oxidation process, which uses Ozone and Hydroxyl Radicals, will totally reduce any soft particles during the 3-minute oxidation period.
The Oxidation process is extremely aggressive and is therefore totally self cleaning (Hydroxyl Radicals at an oxidation potential of 2.8 is only below fluorine). The reaction is unaffected by Chlorides (salts) up to 30%. The system can also handle oils, fats and calcium up to 12.5%.
The reactor is simply a mixing chamber constructed of Stainless Steel or Hastelloy (Hastelloy if HCL is used as an acid or if chlorides are present). The reactor is fully welded and never requires cleaning, service or replacement.
The sample system uses a variable volume method with samples of 10ml for 0-125mgC/l down to 0.4ml for ranges up to 5000mg and 0.08ml for ranges up to 25,000mgC/l. A single instrument can therefore operate across a very wide range as follows:
 |
0-10mgC/l to 0-12,500mgC/l |
| Measuring Frequency: typically 6 minutes | |
 |
0-10mgC/l to 0-25,000mgC/l |
| Measuring Frequency: typically 10 minutes | |
 |
0-5mgC/l to 0-1,000mgC/l |
| Measuring Frequency: typically 6 minutes |
A 2mm particulate will pass freely through all sample components to the reactor, and such a particulate may even be present within the smaller sample selected for the higher ranges.
The absence of filtering ensures that the BioTector measures a fully representative sample. This in addition to providing a more accurate TOC measurement also means that a good co-relation to laboratory BOD or COD measurements can be achieved.
Due to the self-cleaning technology, the large system tubing and the absence of filtering, service is required only two times per year.
The BioTector TOC Analyzers have been installed in over 500 applications Worldwide, many of which would have been considered unsuitable for On-line TOC Analysis prior to the advent of the Biotector Self Cleaning Technology.
Difficult applications include:- Dairy Plants on cream or casine lines, Pulp and Paper Plants on process water lines, Raw Sewage Measurement and many applications within the Pharmaceutical/Chemical industry with high salts, high sludge etc.
