WATERTEC UF plants are built with hollow fiber membranes, to purify surface or groundwater from suspended solids, colloids and all kind of micro-organisms such as bacteria, virus, protozoa, germs and larvae. Ultrafiltration is also commonly used as a reverse osmosis plant pre-treatment. Physically functioning, water ultrafiltration is filtration system by hollow fibers membranes which has a cut-off of 0.01 µm. Our hollow fiber membranes have cut-off equal to 0.01 µm whether 10,000 times less thin than a human hair. All smallest microorganisms are retained at fiber surface. Our ultrafiltration cartridge are made up of thousands of hollow fibers and dispose of an huge filtration surface allowing important flow rate of treatment for a low cost investment in addition to be able to do compact system. The ultrafiltration allows to design water treatment station with a high flow rate of treatment and very low pressure needs (0.5 bars to 1.5 bars). This means that operating costs are low in addition to a low starting investment. Due to a possibilities to backwash the membranes, to high resistance to chemical and chemical agression and to a low pressure need, UF membranes have very good life time.
Ultrafiltration (UF) membrane treatment systems are manufactured 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.
Ultrafiltration (UF) Systems are available in complete and skid mounted form. These systems are tested before delivery.
WATERTEC Ultrafiltration Systems are available in two configurations:
Outside-In Configuration UF Systems: They use DOW UF low fouling Hydrophilic Polyvinylidenefluoride (H-PVDF) hollow fiber ultrafiltration membranes, and is recommended for applications with feed water higher than 150 ppm total suspended solids.
Inside-Out Configuration UF Systems: They use Inge dizzer® XL low fouling hydrophilic MPES hollow fiber ultrafiltration membranes. Dizzer XL UF membranes are provided with Multibore® technology for superior membrane integrity (robust membrane).
Ultrafiltration Systems Using inge Hollow Fiber Ultrafiltration Modules
Multibore® Membranes: The patented Multibore® membrane technology combines seven individual capillaries in a highly robust fiber - an arrangement that significantly increases membrane's stability and eliminates risk of fiber breakage. The membrane provides a secure barrier against suspended solids, bacteria, viruses and other microorganisms and supplies a consistently high level of filtrate quality, even in cases where the composition of original water varies.
Dizzer® Module: Compact and high-capacity ultrafiltration. Due to an optimum hydrodynamic design combined with treatment efficiency of Multibore® membrane, dizzer® module sets new standards in ultrafiltration technology.
T-Rack®: T-Rack® is an integrated, ultra-compact rack system that is equipped with dizzer® XL ultrafiltration modules. The inlet and outlet lines are already integrated in end caps - a design feature that makes system's footprint considerably smaller.
HYDRAcap products contain capillary fiber membrane made from a hydrophilic polyether sulfone, with a nominal molecular weight cutoff of 150,000 Daltons. Feed water enters the center (lumen) of fibers and permeates through membrane radially outward, producing a filtrate turbidity typically less than 0.07 NTU. The HYDRAcap modules in these systems are operated in directional flow (dead-end) method, where all of the feed water is converted to filtrate. The ultrafiltration modules are regularly backwashed to restore permeability, which declines as solids build up on the membrane. The pH tolerance (1.5-13.0) of membrane allows for addition of chemicals for cleaning and chemically enhanced backwashing.
Designed to produce clean, purified water from tap or well water, these wall-mounted systems use high efficiency ultrafiltration membranes. The filtered product water is used in commercial and residential POE / POU applications such as water stores, RO pretreatment, whole house, laboratories, bottled water and other similar applications.
Selection of a plant depends on application, water quality and water consumption. Our water experts are at your service to ensure the best customized solution.
