| Solids and sludge, which are input by the pump in the direction of the external cylinder contact, make vortex at high speed and move up along the space in the cylinder. At this time, strong shear happens because of the frictional force among fluids or with the internal cylinder and the difference of shear speed. As a result, solids or microorganisms of sludge influenced by collision, impact, and shear force while moving become corpuscular or solubilized by destruction of membranes. And when they pass through the internal cylinder, cavitation is made; and when cavitation bubbles collapse solids and sludge dissolved, oxidized, and crushed by the local formation of high temperature (about 5,000 ¡É), high pressure (severa Gpa) and radical; then the properties of solids are changed. With cavitation device of an orifice type installed at the back, Powermax can expedite solubilization using its simple structure and multi-functions. |
(1) Spillover Effects
¡Ü Improvement in environment
- Possible to solve such environmental problems as pollution by abandonment of wastes into the sea, atmospheric pollution by incineration, and pollution of underground water by reclamation; Possible to be applied to various fields.
¡Ü Economic effects
- Possible to create energy by reducing and solubilizing sludge at low cost
- As a simple and multi-functional device, economical and cost-effective to maintain. |
(2) Practical application
¡Ü Compact pretreatment facility to produce bio gas and reduce sludge
¡Ü For changing the properties of high-concentration organic solids and improving the biological treatment function (anaerobic & aerobic)
¡Ü Not required to enlarge the existing overloaded biological treatment plant
¡Ü For research of cavitation and application of computation fluid dynamic model (CFD: Fluent) |
