DWG ASSOCIATES provides objective, independent, unbiased, and cost effective engineering services, plant operations assistance, and training programs for the wastewater and water treatment marketplace. We specialize in pure oxygen wastewater treatment processes like the UNOX and OASES Systems and water treatment systems using oxygen gas.
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 or properly evaluating your aeration equipment. Our design simulation software combines IAWQ biological models with multicomponent gas phase mass transfer models, allowing us to model and/or design any covered aeration system. With DWG ASSOCIATES you won't need to guess at aeration power requirements, you’ll know exactly what you need to efficiently accomplish your objectives.
Cryogenic oxygen generation is NOT standard environmental or wastewater engineering. If you’re baffled by what goes on inside a cryogenic coldbox, 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.
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 high purity oxygen things. 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 can help with annual PSA tune-ups and cryo plant turnarounds too.
