A continuous method using gaseous carbon dioxide or a pressurized flow of liquefied carbon dioxide is described to reduce microbial andor enzymatic activity in a liquid product. An input picture 100 is read out in an amount corresponding to a number of lines required for wavelet transform and buffered in a memory unit 6. The SCA generator also includes a matching module configured to match a service identifier received with the input instructions to service metadata stored in the Metadata repository and a retrieving module configured to retrieve service parameters for the matched service. Said unit comprises a conveying device with a conveyor belt for advancing the containers in the direction of the longitudinal axis thereof, and rotating rollers that are provided with a surface area and can be moved from a neutral position into an identifying position in which said rotating rollers disengage the container from the conveying device and make the container rotate. Once calibrated, the detector circuit further provides an electrical bias to the APD to process or condition the electrical signal to produce a detector output.
