A team of researchers from the Consejo Superior de Investigaciones Científicas (CSIC) has demonstrated that applying alperujo, one of the waste from the production of olive oil, soils contaminated with trichlorethylene achieved a remarkable reduction of pollutant . The study represents at once a solution for managing alperujo and for the treatment of soil contaminated with hydrocarbons. The research is published in the journal Environmental Science & Pollution Research.
"The alperujo treated vermicompostaje reduced by one month 30% of the contaminant, avoiding passing the deeper layers of the soil and reducing the risk of contamination of groundwater. Furthermore, it was degraded completely absorbed in the soil , "explains Emilio Benitez, of the Experimental Station of Zaidín (center of the CSIC in Granada).
Any process that must be monitored sensors required to know the variables of a process in real time. If required to monitor a large number of process variables in the same proportion will require a large number of sensors for these variables. The sensors are expensive, require maintenance and may be calibrated to be very sensitive, plus they need a "hardware" that connect to the monitoring unit. Would not it be better if you could spare some few sensors and still be able to monitor the entire process?
This is the aim of so-called "virtual sensors" or "Software Sensors", better known in the control engineering as "observers" or "state estimator". Observers are computer programs from the measurements obtained by a number of real sensors, to estimate the process variables that does not have its respective sensor. The program reproduces the observed system giving you the information of what the stimuli (inputs) that receives the actual process. A second source of useful information for the observer is the data received from the monitoring system performance (outputs).
METTLER TOLEDO Safeline, the worldwide leader in metal detection equipment and X-ray inspection, introduced Tablex 2 metal detector to detect metal contaminants in pharmaceutical and nutraceutical tablets in accordance with Good Manufacturing Practices.
There are several ways of introducing physical contaminants in pharmaceuticals and nutraceuticals, for example, through raw materials suppliers, broken or crushed mixing blades, damaged screens and sieves and process modeling of capsules and tablets as metal on metal. Good Manufacturing Practice (GMP) need to have protection product inspection in critical control points in the process, including the Board of mixing / grinding, the Board of tablets and final packaging areas.
