Need assistance with covered aeration basins? DWG ASSOCIATES’ personnel helped invent high-purity oxygen (HPO) aeration in the 1960s and 1970s. We know how to convert manufacturer's air-based standard mass transfer efficiencies to a high-purity oxygen atmosphere. That’s the key to optimally sizing your aeration equipment. Our design simulation software includes IAWQ biological models with multicomponent gas phase mass transfer models that allow us to model, or design, any covered aeration system. With DWG ASSOCIATES you won't need to guess at aeration power requirements. You’ll know exactly what your minimal power needs are.
Cryogenic oxygen generation is NOT standard environmental or wastewater engineering. If you’re baffled by these behemoths, DWG ASSOCIATES can simplify things for you. Our personnel have made careers working in the industrial gas business. We understand reversing heat exchangers (even non-reversing ones) & switching valves, prepurifiers, expansion turbines, and the cryogenic distillation process that’s going on inside that coldbox. With our assistance you’ll not only come across as an oxygen production expert, you will be one.
Just need annual or five year turnaround help? DWG ASSOCIATES has the lowest cryo plant turnaround rates in the marketplace. Give us a try, you will not be disappointed.
PSA, VPSA, LOX, "New" Oxygen Processes, & BNR
High-purity oxygen (HPO) and water, that’s what we do! We know what’s new in the HPO wastewater and water markets as well as what’s old. We’re independent, unbiased, and expert in all things HPO. If you need help understanding what does or, maybe more importantly, what doesn’t work with oxygen wastewater and water treatment, that's our buiness. Whether you need to know about oxygen BNR, oxygen mass transfer equipment, oxygen production or supply, or what might be done with an antiquated HPO instrumentation system, we’re here to help. And don’t forget, we do annual PSA tune-ups (and cryo plant turnarounds) too.
