• New small and medium scale cost-effective “next-gen”technologies have become available but these often require moreexamples, proof of life and precedents before they are generallyaccepted.

• TUMWATER is a collaborative alliance for newly launched

technology companies to cooperate on a substantial level toprovide integrated solutions for the delivery of equipment andservices to general industry and to sustainable communities.

• TUMWATER Triple MMO™ Platform is being built to providecomplete integration of alliance partners technologies, productsand solutions offering (marketing, process simulations,economical and treatment performance projections).

• The TripleMMO™ interface caters to practitioners and will providethem access to configure manageable and affordable integrated

solution options to select, approve, fund, and execute at scalerenovation projects or new equipment installations.

Conventional Airlift Pump vs. Geyser Pulse Pump

Better Pumping, Lower Energy Requirements



Problems•Uneven flows (Flow Equalization and Recirculation forBNR)•Carbon starvation in bio-nutrient removal (BNR)•High energy consumption (Aeration)•Segregation/ Channeling/ Frequent shut downs•Grit Trapping/ Sludge Accumulation/ Reduction of capacity

Solutions

•Adjusted Flow Equalization and Recirculation rates•Eliminated grit and sludge build-up in all tanks/basins•Improved sludge mixing in anoxic zones, and in aerationprocess basins/tanks•Enhanced aeration efficiencies, better pumps and mixers
