Membranes

Separates Aqueous Solutions

NDT Products' wastewater filtration equipment uses membranes to separate aqueous solutions, emulsions, and suspensions.  Membrane filtration can either:

• Recycle the valuable chemistry for re-use
• Minimize waste volumes by extracting the water for discharge
• In close-looped systems; discharged water can be recycled

NDT Products' membrane elements are offered in a variety of pore sizes, dimensions, and feed spacer thicknesses to fit almost any wastewater application.

Key Features:

• Polymeric, thin-film membrane
• Patented back-to-back, FleerFlo™ feed spacers
• Uniform pore size and a high degree of porosity
• Smooth surface desirable for fouling reduction
• Smaller pores near surface, control rejection
• Good resistance to pH and temperature
• 94 mil. pore size; other pore sizes available

Applications:

Nano-Filtration Membranes (product numbers ending in '232')

• Dye penetrant applications

Ultra-Filtration Membranes (product numbers ending in '444')

• Aqueous (water-based) cleaners from parts washers, floor cleaning, equipment wash-down, etc.
• Machine coolants and water-soluble cutting oils
• Air compressor condensate
• Water-based ink washed from printing
• Oil/water emulsions
