DESCRIPTION AND WORKING PRINCIPLES

X2 Solutions have developed, with the useful support of branch experts, the project and the construction of low-speed surface aerators called OXAIR. Surface aerator OXAIR type is an optimal solution for aeration in waste-water treatment plants. Characteristics of this aeration system are:

Easy planning and building of oxidation tanks

• Oxygen supplying easily adaptable to process conditions
• Low plant cost
• Low operating cost
• Low maintenance
• Optimal operational regularity and reliability

FIELDS OF APPLICATION
Surface aerator OXAIR type is planned to supply oxygen in sludge oxidation tanks with a high mixing capacity. Its optimal field of work is:
*Activated Sludge tanks in biological waste-water treatment.
*Pre-aeration in homogenization basin
*Tanks for aerobic sludge stabilization
*Aeration of lagoons
OXAIR Aerator type can be installed on fixed platform or on floating pontoon.

IMPELLER

Radial vane centrifugal impeller of semi-closed channels type, with dynamic and static balancing, is made of welded carbon steel or stainless steel. This impeller type guarantees a high oxygen transfer efficiency and a high pumping capacity.
Impeller is projected to obtain a control of oxygen transfer by changing:

• Sense of rotation
• Immersion of impeller

Rotation speed
Oxygen supplying is comprised in a 30% to 100% range of maximum capacity.
