Ultra Pure Water Filtration
Global Filter offers a complete range of filtration solutions for applications requiring ultra pure water.
As a French manufacturer of filtration elements,we help our customers achieve the highest purity standards by designing filtration systems that ensure reliable,
consistent water quality fully compliant with international regulations.
Ultra Pure Water : a Matter of Quality and Compliance
With a global market expected to exceed $13.5 billion by 2030, ultra pure water is no longer just a technical requirement, it is a true competitive factor. Regulations such as FDA, USP, AAMI ST108, and European directives 1935/2004 and 10/2011 demand a superior level of control.
Water quality has a direct impact on product performance. Achieving 18 MΩ resistivity, removing bacteria and endotoxins, or guaranteeing sterility is only possible with a properly engineered filtration chain.
Typical Applications
Pure Water
- Mixed Bed Ion Exchange
- Water Conductivity Systems
- Boiler Feed Water
Ultrapure Water
- Semiconductor Manufacturing
- Water For Injection (WFI)
- Laboratory Grade Water
Ultra Pure Water Production Process
Producing ultra pure water is not achieved by a single filter. It requires a sequence of filtration barriers, each playing a specific role in securing the process. Every installation is unique: influent water quality, required flow rate, and regulatory constraints directly influence the choice of filtration solution. That is why we design tailor-made systems adapted to the specific needs of each customer.
Clarification and Particle Removal
At the first stage, water is cleared of sediments and coarse particles. Our polypropylene pleated cartridges (PP, PPE, PPI series), high-flow (HFPP), or microglass pleated cartridges (FG, FGE, HFFG series) efficiently filter particles above 10 microns and down to 1–5 microns. These filters protect reverse osmosis units, deionization systems, carbon beds, and ion exchange systems (IEU). For additional pretreatment, depth activ carbon cartridges – GCCB+ Series effectively remove organic impurities from the influent. For high-flow applications, our meltblown cartridges (GWTB, GCTB, GATB) provide a robust and economical solution.
Tank and Vessel Protection
Storage tanks are a critical contamination point. Hydrophobic PTFE membranes (GGPTFE, EPTFE, BRPTFE, PPTFE series) and hydrophobic polysulfone membranes (PSH) ensure sterile venting by retaining airborne bacteria and particles down to 0.2 micron, preventing contamination of the tank and its contents.
Pre-Filtration of Sensitive Systems
An intermediate 5-micron filter can be installed between ion exchange units and storage tanks to prevent the introduction of fine particles, such as fractured resin beads. Our polypropylene pleated cartridges (PP, PPE, PPI series), high-flow (HFPP), or microglass pleated cartridges (FG, FGE, HFFG series) are ideal for this critical role.
Polishing and Bio-Burden Filtration
The final stage aims to virtually eliminate microbial contaminants and meets the strictest requirements, such as WFI production or semiconductor manufacturing. Polyethersulfone membranes (GEPES for electronics, GFPES for food & beverage, PPES for pharmaceutical, BRPES for bio-burden reduction) retain microorganisms and particles down to 0.2 micron. For the most critical applications, our Nylon BRHNY+ membranes deliver proven endotoxin removal, with >9 log reduction validated under ASTM F858-15a testing.
Endotoxin Filtration and Removal
Endotoxins, derived from Gram-negative bacteria such as E. coli or Salmonella, are insoluble, heat-resistant, and cannot be destroyed by boiling.
They represent a major risk in fine chemicals, pharmaceutical, and food industries.
Our BRHNY+ cartridges, featuring positively charged Nylon 6.6 membranes, capture and remove endotoxins down to undetectable levels (<0.005 EU/ml).
Independent tests have demonstrated 100% retention of endotoxins, even after 20 cycles of pyrogenic water filtration.
