BlendAir
BlendAirTM uses custom designed disks to create a vortex to efficiently mix solids or liquids and/or transfer gases into water.
Rapid mixing with BlendAir increases reaction rates, reduces required reaction tank volume, improves use of reagents, and reduces costs of consumables such as polymer, ozone, chlorine, acid, or alkali. High shear on the disks prevents surface fouling, but low shear in the mix tank protects fragile flocs or liquid polymers. By drawing headspace gas into the liquid via BlendAir, problems encountered with conventional aeration or mixing systems such as foaming, release of odours, or splattering of aerosols are prevented.
Low energy and easy maintenance requirements with BlendAir minimize on-going costs and may be top-, side-, or bottom-mounted and can be retrofit onto existing tanks or installed on lakes, ponds or lagoons.
BlendAir requires less resistance to spin the mixing and aeration disks, consuming less energy at lower capital and maintenance costs. No blades means that BlendAir is inherently safe and is not prone to cutting or damaging either equipment or people.
BlendAir floating units can be tethered in place, offering flexibility for ponds or lagoons of varying shapes and depths. Adjusting the stack of BlendAir’s top disks and/or bottom disks is used to address specific mixing requirements. Modular in design, the number of BlendAir units can be increased as warranted. BlendAir is mechanically simple, and will reliably operate year round in any climate.
BlendAir’s dual function of mixing and gas transfer is ideal for sludge ponds where aeration of bottom sediments results in in-situ microbial destruction of solids.
- Aeration and/or mixing of tanks, ponds, or lagoons
- Aerobic biological oxidation to destroy sludge and eliminate odours
- Augment overall treatment capacity of wastewater treatment plants
Sizing: Each 8” BlendAir unit has a working diameter for efficient mixing of approximately 50 m in ponds. This rule of thumb is a starting point for pond upgrade with BlendAir. However, the amount of oxygen transfer needed to attain a dissolved oxygen concentration to address challenges such as odour, algae, and organic overloading is site specific.
