NORAM’s patented VERTREAT™ system is a proprietary, high-rate activated sludge effluent treatment process.
High on Environmental Friendliness
The low visual impact of VERTREAT™, self-contained and largely hidden from view underground, gives it a significant advantage over the large surface tanks
of a conventional plant. The subsurface and aerobic nature of the process provides a aesthetically pleasing and safe working environment with low maintenance
High on Land use Efficiency
VERTREAT™ typically uses 10-20% of the total land required for conventional activated sludge plants of equivalent capacity. This represents a considerable
savings in capital cost while significantly reducing environmental impact.
High on Performance
The high oxygen transfer in VERTREAT™ enables rapid treatment of high-strength waste streams. Even at high BOD loads, the VERTREAT™ process is not
limited by oxygen availability.
The VERTREAT™ process uses a submerged hyperbaric aeration system, which has been proven effective through more than 30 years of
commercial operation in biological processes.
The VERTREAT™ patented design gives it the following advantages over conventional effluent treatment systems:
• Very low VOC and odor emissions reduce environmental
impact and increase safety
• Highly efficient oxygen transfer (> 65% OTE). With this low
process air requirement, off-gas is minimized
• Effectively treats difficult waste streams, including streams
with fluctuating loads and streams prone to foaming
• Competitive on costs, both capital and operating. Low energy
requirements and low maintenance costs contribute to low
operating costs (roughly 50% of conventional systems)
• Minimal footprint requirement – the small size of VERTREAT™
facilities means more potential sites can be considered for new
or retrofits can be made to existing sites that have
insufficient space for expansion
