I'm working on a soil vapor extraction (SVE)/sub-slab depressurizatation system. I want to use 2" PVC pipe routed through the building space to connect the roof mounted blower to the SVE points on the floor. I'm wondering if anybody has a refference for pipe air flow limits for silent...
Thanks for such a quick reply.
Your right that the GW pH is unusual, it is do to past waste acid releases/"disposal". The price difference for the largest of the four pumps (model 150S(N)75-4) is $2,000 vs $3,500. (The formula for cost of 316ss for all Grundfos submersables is 1.5 x 304ss...
I'm working on a pump and treat system for a contaminated groundwater site with low pH (3.1-4.5). My consern is with the material compatibility and life span of the well pumps. It is predicted that the system will operate for 15 years. Grundfos claims that the typical application is pH...
