APPLICATIONS
CRYSTOLITE

CRYSTOLITE – Microfiltration Media has been developed after several years of extensive, real-world and field-testing to ensure an unrivaled degree of harmful solids and heavy metals removal from water systems. It reduces conductivity levels which is caused by micro-solids. Additionally, CRYSTOLITE – Microfiltration Media can provide water filtration 5 – 8 times greater reduction of harmful-solids & SDI reduction than its closest competitors. Using CRYSTOLITETM media in a pressure vessel to provide a microfiltration effect, the CRYSTOLITETM media allows the water to flow through the top distributor on the top of media layer, when suspended solids are held on the highest surface area of the media allows only clean water to flow through the CRYSTOLITETM media. As a result, CRYSTOLITETM can be used to filter down 0.5 microns without clogging. It allows all suspended solids to accumulate on the surface of the CRYSTOLITETM media and are easily backwashed to drain.

The system can be designed either manual backwash or by using automatic backwash cycle, the backwash cycle is maximum of 10 minutes which uses 80% less water than any traditional anthracite or multimedia filters, it is because 90% of the solids are captured on the surface and not inside of the CRYSTOLITETM media-bed. This results if the High-tech filtration that can filter solids and particles down to submicron levels at 10 to 15 times the flow rate of all traditional filters. Backwash water reduction is up to 80%.

QUESTIONS

CRYSTOLITE™ is a unique, high-performance microfiltration media manufactured in Germany. It is a reddish crystalline granular material designed to filter out suspended solids and particles down to 0.5 microns, serving as a robust and cost-effective alternative to membrane systems and cartridge filters.

CRYSTOLITE™ provides exceptional microfiltration, effectively removing particles down to 0.5 microns.

The media works by surface filtration. Suspended solids and microparticles are captured on the large surface area of the media granules, allowing only clean water to pass through. This surface capture makes it highly efficient and easy to clean via backwashing.

  • Much finer filtration (0.5 µm vs. 15–20 µm)
  • Significantly higher flow rates (15–30 m/h)
  • Up to 80% less backwash water usage
  • Longer lifespan (10–15 years)
  • Smaller, more compact system footprint

Yes. One of its main applications is as a pre-filter for RO and UF, where it reduces the Silt Density Index (SDI), protects membranes from fouling, and extends membrane life.

Because most solids are held on the surface of the media and not deep in the bed, they are easily dislodged. This leads to shorter, more efficient backwashes, using up to 80% less water.

Optimal service flow is 15–30 m/h, which is 10–15× higher than sand filters. Backwash velocity: 20–25 m/h for 5–10 minutes.

In addition to fine particle removal, CRYSTOLITE™ can also remove:

  • Ammonium ions (pH-dependent & Oxydes; best results at pH 8.5–9.0, capacity ~250 mg NH₄⁺/L media)
  • Heavy metals such as copper and zinc (up to 98% Cu and 95% Zn removal at 15 mg/L).

10–15 years, depending on application and conditions.

Yes. CRYSTOLITE™ is highly resistant to chemicals and oxidants and operates within an inlet water pH range of 3–12.

Yes. CRYSTOLITE™ is certified to NSF/ANSI/CAN 61.
Available certification from Water Quality Association (WQA) and The International Association of Plumbing and Mechanical Officials (IAPMO).
