NORAM holds a number of patents for VERTREAT™ (VERtical TREATment), a high-rate activated sludge process, and VERTAD™ (VERtical Thermophilic Aerobic Digestion), an auto-thermophilic, aerobic sludge digestion process.The VERTREAT™ process provides high-quality effluent from industrial and municipal waste streams. Efficient oxygen transfer and low power requirements reduce operating costs by 50% compared to conventional systems. The VERTAD™ process achieves greater than 40% volatile solids reduction in a four-day detention time, producing pathogen-free Class A biosolids faster than any competing digestion process. Both VERTREAT™ and VERTAD™ use an in-ground vertical aerated shaft, a patented design that offers compelling cost and operational advantages. This design results in a smaller reactor volume and reduces overall energy consumption by more than 50%, giving VERTREAT™ significant capital and operating cost advantages over conventional treatment systems. The in-ground installation of the processes requires only one-tenth to a third of the land needed for conventional treatment systems, offering flexibility in site selection and reduced visual impact of the treatment plant. The enclosed nature of the processes eliminates nuisance odors, allowing installation at sites in close proximity to residential areas.
