LemTec - Aeration Technology
LET Aeration Technologies promote biological oxidation and ensure that all water and microorganisms come into contact with oxygen, delivering maximum wastewater treatment results. LemTec™ Aeration Technologies are a complete line of durable, dependable surface and sub-surface aeration technologies, comprised of high-quality fine bubble diffusers, coarse bubble diffusers and mixers that promote the oxygenation and circulation necessary to meet our clients’ treatment objectives. LET aeration technologies can also be retro-fitted or implemented as an adjustable stand-alone solution to address the needs of specific sites based on their individual parameters.
Surface Aeration Technology
LET Surface Mixers agitate wastewater and allow it to come into contact with the air for effective, consistent oxygen transfer while creating controlled mixing patterns by effectively re-suspending solids and also eliminating the risk of short-circuiting. With a critical role in the biological treatment process, LET is able to achieve higher removal rates of BOD and suspended solids with easy to install, maintain and operate surface mixers.
Subsurface Aeration Technology
Exceptionally effective and energy-efficient, LET utilizes sub-surface Fine Bubble Diffusers to produce a large volume of tiny, slow-rising, buoyant bubbles that deliver substantial and efficient mass transfer of oxygen to the water, a key component in successfully treating wastewater. Reliable and effective, the sub-surface Coarse Bubble Diffusers are an essential component to the treatment process as well, providing turbulence and mixing action that re-suspends settled solids. This extends and maximizes the treatment process, helping to ensure that LET customers are able to successfully meet increasingly stringent effluent limits.
LET is committed to continuously advancing wastewater treatment processes and related technologies, including our LemTec™ Aeration Technologies. We do this by continuously improving and expanding upon our treatment designs and service offerings. Our “Circle of Innovation” philosophy ensures that the needs of our clients are met efficiently, effectively and cost-consciously as we work together with our municipal and industrial clients, protecting water resources now and for future generations.
