APPENDIX A: GENERAL WORKING OF THE BACTCONTROL
The concentration of E.coli, coliforms and total activity are determined based on the
presence of enzymes which are specific for these bacteria. Each enzyme has its own
optimum so the measurements must be done separately, meaning that during each
sequence only one type of enzyme can be detected.
The sample goes through the inlet into the reaction chamber, where is concentrated in
the ceramic filter and is brought into the temperature, depending on the enzyme to be
determined. For a general view of the BACTcontrol flow scheme see Figure 31.
