The owner was not looking for the cheapest solution, just the best value and microBLOX fit that best value.
DESCRIPTION
Tucked into a private canyon in the Upper Napa Valley on a 157acre site marked by ancient oaks, majestic hills, a rockhewn stream and private lake.The 48room luxury resort captures the rich cultureof food, wine and nature inherent to the region.
With the existing Smith & Loveless Fast system failing, the owners considered MBBR and MBR. The Ovivo microBLOX™ MBR System was chosen for it’s superior quality, quick delivery and ease of installation.
The four stage process is completely contained within the single structure, which includes headworks through to and including disinfection. Process zones for PAX, PA, AXP and MBR provide the necessary treatment for tight nutrient limits.
