STARpro – the platform for large and complex treatment plantsSTARpro is the professional and right choice for online control of large, complex treatment plants: Allowing comprehensive solutions integrating the control of treatment plant and sewer system. Highly robust solu-tion with precision control. Many control modules for hydraulically improved capacity utilization. Offers a good overview of a large number of modules and treatment plants within the same system.

STARlite – the platform for smaller systemsSTARlite is the cheaper alternative for access to the advanced and well-tested control modules and features used in STAR Control®. The control is developed for small treatment plants where the biological/chemical wastewater treatment takes place in one process line.

Documented advantages of STAR Control® Depending on the choice of modules, the following advantages can be expected with STAR Control® installed:

5-20 % increased treatment capacity10-30% increased hydraulic capacity20-50% improved treatment10-30% reduced energy consumption for aeration5-15% reduced excess sludge quantity20-60% reduced need for precipitant20-50% reduced carbon dosing20-50% reduced stormwater tank volume20-30% fewer overflows

The implementation of the STAR Control® modules will, among other things, allow the treatment plant to utilize optimally its existing process volume such that a planned extension of the plant capacity can be postponed, minimized or even avoided.

With a combination of, for example, ammonia and nitrate online sensors it is possible to reduce the operat-ing costs of the treatment plant to such an extent that the investment can be paid back within a few years. Hereafter it will be pure savings on the operating budget.

If a calculation of the savings potential is desired for a specific treatment plant or sewer system, Krüger of-fers to make a pre-study.

STAR Control® gives access to the latest know-how in “real-time” control of sewer systems and wastewater treatment plants – wheth-er in dry weather situations, in heavy rain or during periods with snow melt. The wastewater system is upgraded to effective utilization of available storage volumes and mechanical equipment with cutting-edge real time control technol-ogy. Infrastructural investments can be postponed or even avoided, at the same time as the operating economy and the environment can be signifi-cantly improved.

Modular systemSTAR Control® is a modular system that can be tailored to any wastewater sys-tem, whether there is a need for stand-alone online control of a wastewater treatment plant or sewer system, or a need for total solutions with integrated control of the entire wastewater system. The complexity of the control is also optional and ranges from radar-based forecast control to simple unit-based PID regulations.All modules in STAR Control® are compatible allowing, for example, a small treatment plant to start “small scale” with a few simple control modules, and then later extending with more control modules or more complex control modules, or possibly inte-grating the control of sewer systems and several treatment plants.The STAR Control® interface ensures uniform access to the processes in the various types of treatment plants and sewer systems that a utility company typically consists of. It is known from experience that this saves time and reduces the number of errors in the daily operation. At the same time, the educational interface gives a boost to the level of competence and knowledge.
