Defoaming
TrumpJet Mixing of Defoamer
The good mixing of defoaming agent is vital for effective removal of excessive entrained air from white water and for the prevention of foam build-up. TrumpJet Poco for defoaming agents optimizes the usage of additives and significantly reduces consumption. It guarantees effective foam control, a cleaner and more stable process with less dirt deposits in the process and on fabrics.

Increase the efficiency of defoamer by fast and homogeneous mixing
The uniform distribution of defoaming agent throughout white water plays a pivotal role for its effect.
The mixer TrumpJet Poco is specially designed to mix very small chemical flows into large process streams. It guarantees homogeneous distribution of the defoamer, which is usually so small in volume that it is difficult to mix properly with conventional methods. No need to wait for the process tray water to make a complete loop/circulation for a decent effect.
With TrumpJet Flash Mixing for defoamer, the process is stable and the entrained air and foam are in control.
Reduce defoamer consumption by half and avoid the adverse effects of overdosing
Good mixing and flow homogeneity significantly improve the performance of defoamer, allowing the desired effect to be achieved with a considerable reduction in consumption, often about 50%.
By enabling much lower defoamer consumption, TrumpJet easily prevents numerous runnability and quality issues caused by severe overdosing, a common practice to compensate for the inefficiency of poorly mixed defoamer.
It prevents the accumulation of dirt and tacky deposits, reducing washing needs and extending the lifespan of machine fabrics. It also prevents the negative impacts that too much defoamer has on the performance of sizing agents, retention aids, and dry strength agents, in this way optimizing the effectiveness of all additives, leading to a 50% reduction in consumption.
