Waste water treatment

1. Water treatment: Vapor compression; water distillation; aeration of streams; lime-neutralization aeration; air flocculation for water purification; saline water desalinization; salt water desalinization.

2. Aquaculture: Aeration of fish tanks, transport trucks, and ponds; prevention of ice formation on ponds; removal of eggs from fish; agitation of washing tanks.

3. Dairies: Pressurizing tanks or trucks; evaporation for drying milk; aeration of milk wastes; gentle aeration in bulk storage to prevent butter fat separation; vacuum for milking machines.

4. Ice: Aeration of lakes and ponds for protection against freezing; agitation by bubbling water in marinas, dams, bridges, etc. where freezing may cause damage; aeration of  harbors to keep open for navigation; aeration of freezing tanks in ice plants to draw off impurities and to provide clearer cakes of ice; conveying crushed ice into ice bunkers on boats, ships, trucks, and railroad cars.

5. Paper Mills: Paper machine vacuum; head box pressurization; pneumatic conveying; waste treatment aeration; paper folding; vacuum pick-up of sheets; air glide or cushion for moving heavy loads on flat surfaces; vacuum cleaning/conditioning of felts; roll heading for wrapping; black liquor recovery.

6. Pulp Mills: Chip conveying; combustion air; vacuum filtration; pulp drying; black liquor recovery.

7. Sewage: Aeration in activated sludge plants --- industrial, municipal, commercial (hotels/motels/sub-divisions/ships, etc.); separation of grit from sewage; grit channel aeration (prevents settling of grit); pneumatic conveying; dewatering sludge on vacuum filters; recirculation of sludge gas; cake blowing; combustion air for incineration.

It is used for aeration and the stir in the water treatment plant.
