Scale Removal 

Although scale can be, to some extent, eliminated by controlling flow rate, pressure, temperature, inducing precipitation, and adding acids or threshold chemical scale inhibitors, these methods can impact environment, lifespan of facilities, operation, and production negatively, and also they are generally very costly and cumbersome because of requiring hard and extensive labor works.

Utilizing ultrasonic methodology, the Morko USP has provided a new, cost-effective, physical solution for the elimination of scales lining the surface of metallic pipes. As the USP device adopted fundamentally different paradigm from existing technologies, it has achieved great success in preventing and eliminating various scale minerals in pipes. 

Scales have numerous invisible micro-cracks within their buildup on pipe walls all the times. This can be attributed to the difference in thermal expansion coefficient between scales and metals. As almost all of thermal facilities and their associated equipment commonly undergo frequent temperature changes, they are subject to repeated thermal expansion and contraction. Due to this phenomena, the micro-cracks develop and grow within scales or along boundary between scale and substrate.  

Numerous small bubbles (air bladders) generated due to cavitation process infiltrate into micro-cracks as shown below, and repeatedly explode with very high energy force within the cracks. Due to this high powered energy that is generated locally by explosion, scales are broken down and eventually dropped off from its substrate.
Scale Problems

Scale is a common and persistent nuisance in various industrial fields. Scale problems are often caused by the deposition of precipitate(s) from solution supersaturated with respect to scale mineral(s). The accumulation of scale mineral(s) commonly disturbs fluid flowing due to the blockage of tubing or pipelines.

To date, two most common scale-forming minerals which has been a 'pain in the neck' to field engineers are calcite and struvite. Frequent cleaning of pipelines to remove these minerals results in substantial increase of operating cost.

Scale Prevention

In order to prevent or minimize scale deposits, various attempts have been made. A common method is to utilize special chemicals called 'threshold scale inhibitors'. These chemicals help prevent the nucleation and formation of scale minerals formation by lowering their concentrations in solution through reactions with chelating agents. In general, this method seems to be  very costly and also is not free from environmental issues.

The Morko USP is a device designed to prevent scale formation within pipeline or thermal facilities. Unlike prevailing chemical solutions, this device utilizes the vibration energy of ultrasonic sound waves generated by 
a USP generator and transmitted by its transducers. Solid metals in contact with these transducers and surrounding fluids in flow are both subject to continuous vibrations and acoustic streaming whereby the formation and accumulation of scales can be substantially surpressed. This is a very cost-effective and environmentally friendly method to prevent scales and could pave a new way of achieving it.
