Industrial Nanofiltration: Precision Separation for Demanding Applications

Vontron's industrial nanofiltration elements deliver exceptional performance across a wide spectrum of applications. The VNF1 and VNF2 series (8040, 4040, and 2540 configurations) offer rejection rates of 97-98% with permeate flows up to 10,500 GPD, making them ideal for water treatment and softening applications. The TAPU municipal water series (4S, 4HS, 6HS) achieves rejection rates of 95-96% with flows up to 12,000 GPD, specifically engineered for municipal water treatment with mixed salt solutions (NaCl, MgSO₄, CaCl₂). For specialized material separation, the MASE series (SP, SL, PS) delivers 90-98% rejection at 1,200 GPD, providing precise molecular-level separation for industrial processes.

Industrial Ultrafiltration: Robust Filtration for Challenging Feedwaters

Vontron's ultrafiltration membrane elements are available in spiral-wound, flat sheet, and hollow fiber configurations. The VUF8040 spiral-wound series offers permeate flows from 6,500 to 25,000 GPD with molecular weight cut-offs ranging from PEG 4,000 to BSA, providing flexible solutions for various filtration requirements. The hollow fiber UF elements (VUF-2860, VUF-2880) feature PVDF membrane filaments with nominal apertures of 0.02 μm or 0.08 μm, manufactured using both NIPS and TIPS processes to deliver system fluxes of 30-120 LMI. These elements are widely used in wastewater treatment, RO pretreatment, and surface water filtration.

Residential RO and NF: Pure Water for Millions of Homes

Globally, more than 70 million households trust Vontron residential elements for their drinking water needs. The HP Series (1812, 2012, 3012 configurations) delivers permeate flows from 50 to 600 GPD with rejection rates up to 99%. The High TDS Series (HT3-1812, HT3-2012) is specifically designed for challenging feedwaters with high total dissolved solids. The Mempro Series and ULP Series (ultra-low pressure) offer energy-efficient operation with flows from 75 to 1,000 GPD, while the HOR Series provides reliable performance for standard residential applications. For homeowners seeking selective removal of specific contaminants, the residential NF series (VNF-1812, VNF-2012, VNF-3012) offers an ideal solution.
