VACUUMING UNITS «AQUASTREAM VU»

Installations for sludge slurry vacuumization are designed to intensify the biochemical processes of nitro- and denitrification, the acceleration of sedimentation of suspended solids in secondary settling tanks and to prevent sludge carry-over with wastewater.

Application:

Biological wastewater treatment technology, including the processes of nitri-denitrification and biological dephosphatization.

Advantages:

• Intensification of biological treatment by 20-30% by increasing the concentration of activated sludge in the aeration tank to 4-6 g/l;
• No flotation and sludge removal from the secondary settling tank;
• reduction of the size of the sedimentation tank due to 15-20% increase in the sedimentation rate;
• easy maintenance;
• low capital and operating costs - alternative to MBR and MBBR.

Equipment:

• Stainless steel vacuum tower;
• vacuum pumps;
• heated container for vacuum pumps;
• Stainless steel piping;
• Instrumentation and control system.
