Specialities to be considered in the commissioning of biological sewage treatment plants

The ever increasing demands in the area of environmental protection are causing industry and especially the food processing industry to invest large amounts in this area. One of the biggest tasks that companies are confronted with is the realisation of the advanced waste water treatment that meets not only todays demands but also the increasing demands of the future. A high standard in construction and process technology is achieved by using experienced environmental engineers in the planning as well as specialized firms to carry out the project. High investments are needed in order to construct such systems with todays technical standards. The commissioning of such a system and the fine tuning in regard to the optimal cleansing conditions, the minimizing of the running costs and energy used has to a large extent been nelgected up to date. The construction of a sewage treatment plant does not necessarily mean that the plant functions properly. This becomes possible after a professional commissioning, optimization and the running by specially trained personnel. An important point in the commissioning of such a plant is the training of company personnel as well as the writing of a practical instruction manual. These things, as well as the further support of the commissioning company will ensure that the sewage treatment plant will function for many years to come. (orig.)
