Ultrafiltration (UF) Systems:

These Ultrafiltration (UF) membrane treatment systems use UF Hollow Fiber Membranes and are designed to produce clean, purified water from various sources waters, including rivers, lakes, industrial ponds, secondary effluent, well water, and seawater. UF filtrate is used for drinking water, utility water, reclaimed water, food and beverage production, and pretreated source water for RO desalination systems. Skid Mounted or Containerized Mobile Units.

  • Low fouling membrane modules
  • Excellent filtration performance with high flux
  • High chemical resistance and temperature tolerance for effective membrane cleaning
  • Very fine nominal pore diameter (0.02 µm)
  • High removal efficiency of bacteria & viruses
  • Dead-end or concentrate bleed flow capabilities
  • Can be periodically back washed and air scoured to improve performance and extend operating life by removing the fouling layer
  • Simple, vertical, modular design allows low cost, compact systems
  • UF Outside-In or Inside-Out Configuration allows for less plugging and higher solids loading, higher flow area and easier cleaning
  • SS High pressure components, SS Pump
  • Touch Screen PLC Operation

Electrodeionization (EDI) Water Purification Systems:

EDI Series Electrodeionization Water Purification Systems are designed to polish the permeate from a reverse osmosis system. The quality of the product from these EDI systems will depend on the incoming feed water quality to the Electrodeionization System. Product quality up to 18 megaohms is possible with these systems.

The EDI System is superior to a conventional mixed-bed deionization system both in ease of operation and maintenance. In addition, no chemicals are used for regeneration.

The EDI Systems are modular, so they can be designed for various capacities and easily expanded when required.

EDI Systems are used in applications such as ultrapure water, USP grade water, water for injectables (WFI), and removing trace quantities of contaminants.

Self-Cleaning & Backwash Filter Systems: 

  • FF Series Filtration Systems: Uninterruptable Self-Cleaning Filter System: Our automatic self-cleaning filtration systems are cost-effective, produce minimal wastewater, and will not interrupt your process flow during the cleaning cycle. These systems are dependable, low-maintenance, and a highly efficient way to provide sustainable solutions to our customers. No matter what your industry or what your needs we can save you time, water, and money.
  • Back-Wash Filtration Systems: Automated Filtration Systems with reusable filter elements.  Backwash or Back-flushing based on differential pressure.  Custom systems using bags, cartridges, screens, or spinning discs – depending on the application. Various micron ratings, pressures, and removal efficiencies.  Multiple technologies and solutions.

Zero Liquid Discharge (ZLD) System: 

(Click Here for Technical Data Sheet)

Radically New Filter System that utilizes NASA derived, patented Advanced Nano Technology. Smaller footprint and much less expensive that conventional UF & MF filtration systems with No Waste-Stream, No Backwash routine, and No Need for Chemical Cleaning. Removes particulate and biological/pharmaceutical contaminations such as bacteria, viruses, and even DNA. Also removes Iron and other metals. Perfect for Bottle Water Producers, Demineralizer & Ion Exchange Protection, Make-Up Water, and any other application requiring clean, pure water.  Economical Pre-RO system that removes biological burden on RO membranes and extends on-stream life.
