ZERMEG II – Zero emission retrofitting method ... - Fabrik der Zukunft

6 The optimisation approach of ZERMEGZERMEG wants to reach these requirements through following elements:Methodical approachIdentification of the „ideal“: the minimum possible consumption of water andchemicals with the existing configuration of the plantSupport through calculation programsSupport through reference data and standardised descriptions of technologiesOffering of a discussion platform for an exchange of experiences, for the furtherdevelopment of the model and for the diffusion of data (www.zermeg.net )The methodical approach consists of nine steps (table 1, Fresner 2004 c).No. ofstepDescriptionActivities1 Analysis of current situation:Measuring the water consumptionand the usage of chemicals2 Analysis of current situation:measuring of drag out3 Analysis of current situation:Definition of the rinsing criteria4 Calculation for comparison:Calculating the waterconsumption5 Calculation for comparison:Calculation of the consumption ofchemicals6 Definition of possible externaldisposal and recycling options forspent process solutions7 Definition of possible recyclingoptionsCreation of a flow chartdocumentation of the water consumption bymeteringdocumentation of the consumption of chemicalsby data of the accounting departmentimplementation of a bath-specific documentationof the usage of chemicalsThrough measuring, calculation or estimationTarget values from the literature for rinsingcriteria and/or conductivity of the last rinsingwatercalculation of the necessary rinsing criteria frommeasurements in the plantWith the program ZEPRAWith the program ZEPRAContact with potential customers and suppliers,e.g. manufacturers of chemicals for watertreatment and waste water treatmentUse of the register of technologies of closingwater cycles8 Evaluation of the options Evaluation according to financial and sustainablecriteria9 Optimisation of the waste waterplantTab. 1: The ZERMEG Method11
