Top 5 Reasons to choose Pall Pressure Systems over Vacuum Systems |
1. Pall systems power through process upsets due to turbidity spikes and cold source water.
Vacuum systems have a very limited operating pressure range and are therefore more susceptible to process-related shortcomings due to seasonal and storm related turbidity events and cold water flux reduction. Pall pressure systems, on the other hand, can operate at up to 45 psi, which translates into the ability to cope with any process upset. (The typical range is from 7 psi to 30 psi.)
2. Pall systems actually meet US EPA guidelines for integrity.
All Pall MF systems utilize a 20-30 psi pressure-hold integrity test that can detect a 3 ųm breach in 100 modules. This test exceeds the proposed US EPA requirements. Furthermore, because all of our modules are easily accessible, we can guarantee broken fiber repair within 40 minutes—a claim that cannot be made by our competitors.
3. Pall has the most robust membranes in the industry.
While Pall's Integrity Test is considered to be the easiest and most effective method to ensure and maintain system integrity, the truth is that most of our customers will rarely need to repair any fibers. Pall MF membranes are the toughest in the industry, with a chlorine tolerance >5000 ppm, and an empirical fiber breakage rate < 0.00005% per year. * No wonder we offer the longest warranty in the industry.
4. Pall’s cleaning methods are more effective and efficient.
Pall’s closed pressure systems, as opposed to open-tanked vacuum systems, enable the operator to accurately and evenly dose chemicals. Moreover, these solutions can be recovered with little loss or dilution, significantly reducing O & M costs and damage to the environment.
5. Pall systems are the lowest cost.
There are many functional benefits of Pall Pressurized MF plants; however, most purchasing decisions ultimately come down to cost, and that's where we have the competition scratching their heads. In project after project, our 20-year evaluated cost is lowest. Pall pressurized systems, unlike vacuum systems, don't require an overhead crane, don't require excavating and expensive basins, need far less building height (i.e., lower building cost), and are inherently less expensive to purchase and install without sacrificing quality.

With all these benefits why would anyone choose vacuum?
