Analysis and simple treatment tests of industrial wastewater<\/h3>\n\n\n\n

Industrial water and wastewater technology often requires treatment tests to be carried out on a laboratory scale for process engineering reasons or regulatory requirements, as process engineering and\/or system engineering design parameters are not available in the required quality. The experimental tests in the laboratory for ion exchanger processes are usually carried out as column tests in the downflow in accordance with an investigation program that may be adjusted on the basis of interim results. The samples obtained during the tests are analyzed. During the evaluation and documentation of the tests carried out, the design parameters required for the design of the process and system technology are also determined where necessary. When recirculating rinsing water and\/or treating partial (wastewater) streams or when post-cleaning the treated wastewater, meaningful results can already be achieved with the help of laboratory tests that enable the upscaling process. In some cases, however, it is advisable to secure this process via an intermediate step with a pilot or technical centre system. For the monitoring of process-relevant individual steps, the required measurement technology and\/or the analysis methods to be used can be defined on the basis of the test results. <\/p>\n\n\n\n

When inspecting existing systems, the capacity of the ion exchangers<\/a> used is tested according to standardized procedures and allows the current state of the system technology to be assessed and provides information on any deficits that may still need to be verified through targeted treatment tests.<\/p>\n\n\n\n

Depending on the application, it may already be sufficient to determine one parameter, e.g. a monitoring parameter for industrial wastewater treatment in accordance with the German Wastewater Ordinance (AbwV)<\/a>, which is relevant for discharging the treated wastewater into the municipal wastewater treatment plant (indirect discharge<\/a>). If this parameter has been complied with, documentation of the value is sufficient. If an in-house inspection is not possible, this can also be carried out externally by DECKER. <\/p>\n<\/div>\n\n\n\n
