Taprogge system

Additional capital costs for injection equipment will also be involved if it is thought necessary to dose one or both streams with additives to reduce the fouling problem. Consideration of on-line cleaning (see Chapter 15) such as the Taprogge system for cooling water, will also involve additional capital. It has to be said however, that on-line cleaning can be very effective and that the additional capital cost can often be justified in terms of reduced operating costs. 

The use of recirculating sponge rubber balls (for instance the Taprogge system) has found wide application in the power industry for the mmntenance of condenser...

Fig. 16.S is a simplified flow sheet of a power station equipment with a sponge rubber ball cleaning system (e.g. Taprogge system). The technique is described in some detail in Chapter IS. The technique reduces the problem of biofouling, scale formation and particulate deposition. The system requires suitable pumps, filter screens and storage for cleaning devices. In addition to the mechanical treatment (only applicable to the condenser tubes) chemical treatment is also required to combat fouling in other parts of the system.

Computer programmes are used by the system suppliers (e.g. Taprogge) to optimise ball type, hardness, diameter, frequency and cleaning period for given conditions.
