Centrifugal Liquid Recycling

The Discovery of Gravity Cleaning of industrial fluids with Centrifugal Technology STA Centrifugal Separators are using the physical effect of phase separation in centrifugal fields for the cleaning of process fluids. Even unfilterable media are reliably cleared from particles or secondary liquid phases without use of disposables. The removed solids are dry and pure. Centrifugal Separators are relatively compact systems and easy to be integrated; they fit a wide range of applications.

Working principle of solid separation and 3-phase separation (liquid-liquid-solid) inside the centrifugal separator Right and Tight The high acceleration forces also result in an optimum compression of the separated solids. The sludge is dry and can be reasonably disposed or even recycled. ^ Through its rotation the accelerator hub transfers liquid into the rotor. Liquid is accelerated and moved outwards. ^ Particles settle on the inner rotor wall. ^ Backflow of clarified liquid via peeler tube (5 m pump head) 0 In the 3-phase separator a secondary light fluid phase (e.g. tramp oil) is separated...

Centrifugal separators Semi-automatic Aqua Plus version** 1 One for All - the mobile solution STA Separators are very compact and space saving, on top of this they can be done mobile, to be even more all-purpose and flexible. Due to their own backflow pressure there is no installation works necessary apart from connecting two tubes. 2 Ready for take-off within 3 minutes Manual solid discharge is done with almost a flick of the wrist. After only 3 to 5 minutes the separator is ready again for operation. 3 Struck Oil! NZ-50 • compact • direct drive • pressureless discharge fluid-dynamically designed...

Centrifugal Separators Fully automatic 1 The drives: maximum performance and efficiency The innovative drive concept responds to today’s demands for energy efficiency. The inverter controlled 100 Hz drive is more compact than ever, hence very silent and wearless. As an option power modules with low harmonics energy feed-back can be used – saving money and improves solids discharge rate by even shorter the breaking times. 2 Improved casing and valve design Residual liquid drain and sludge drying Thanks to the rinse liquid drain that has been moved upward and the special centrifugal valve design...
