Green Incinerators

Restrictions on land application, increased transportation costs, and concerns about greenhouse gas emissions have sparked wastewater utilities’ interest in alternative solids processing technologies. At the same time, incineration facilities have become more fuel-efficient and
environmentally friendly. But can incinerators be considered “green” alternatives for solids processing? The answer is yes. 


No Space? No Problem!

No Space No Problem!

What do you do when a growing community is replacing aging septic systems with new, centralized wastewater infrastructure, but space constraints at the existing treatment plant limit expansion? Marco Island, Fla., replaced its contact stabilization process with modified Ludzack–Ettinger
(MLE) and membrane bioreactor (MBR) processes. The upgrades not only increase treatment capacity from 3.5 to about 5.0 mgd (13,200 to 18,900 m³/d) but also provide high-quality reuse water suitable for irrigating condominium landscapes and golf courses.
