DIRECT NANO FILTRATION (dNF) SYSTEM

Hardness & Metals removal - COD/BOD/TOC removal - Color & Toxic substances removal - Waste water reuse

dNF - direct Nanofiltration membrane, the pioneer product of NX Filtration (Netherland), with advanced technology, excellent capability and european quality standards, creates the powerfull water treatment solutions, simple configuration but high effectiveness and realibility.

Direct Nanofiltration (dNF) membranes offer the unique combination of a low fouling hollow fiber configuration with the ability to remove organics and salinity (hardness) from water in one simple step. Other than a strainer, no further pre-treatment is required. dNF are produced with a patented layer-by-layer process, where multiple nano-scale layers are deposited on a membrane support. This method enables very precise and controlled rejection and flux properties of the membrane. A unique solution for troubled water.

WASTE WATER REUSE

with WMC200 dNF-40 System

REVERSE OSMOSIS (RO) SYSTEM

Produce purified water - Salt (brine) removal - Water treatment for reuse.

Reverse osmosis filtration technology are more and more commonly due to its ability to remove almost substances in water, technology development helps RO membrane runs at lower pressure (less power consumption), higher stability (less scale formation) and lower cost for investment as well as operation.

SMALL RO SYSTEM

Small RO system are designed and produced by VATECH JSC, with fully pre-treatment (filters, chemical dosing and Ultra-filtration), piping & accessories, electrical & control, on a plug-and-play skit. This compact system are ready to use, make it easily and save time for installation as well as operation & maintenance.

SPECIFICATION

Small footprint, no intermediate tank, pumps and AC Filter / softener.

Total scale & oxidization protection by professional Hydrex chemicals

Ultrafiltration pre-treatment guarantees for long-term operation of RO system

Low-pressure RO membrane guarnatees for low cost operation

Clean-in-place (CIP) unit is equiped for system cleaning at site

APPLICATION

Small capacity RO systems are widely used in industrial plants, to treat high-quality water, bottled water, direct drinking water, and cooking water. The small capacity RO system of VATECH JSC is also perfectly suited to the pure filtered water needs of the smokeless industry, such as high-end restaurants, hotels, resorts & homestays...

With the use of Veolia's Hydrex chemical, which meets FDA requirements and regulations, VATECH's Industrial RO system fully meets the requirements of chemical safety used in food, beverage and pharmaceutical production.

WATER TREATMENT EQUIPMENT AND MATERIALS

Ultrafiltration Membrane (UF) - Dosing pumps & online measuring devices

VATECH JSC cooperates with many domestic and foreign partners, develops products, equipments and supplies for the water industry, used in VATECH systems, and simultaneously deploys market development. Some of the featured product lines are as follows:

LITREE UF MODULE

ULTRAFILTRATION (UF) MODUL

VATECH selects high-end ultrafiltration membrane products from the world's leading membrane manufacturers, with big brands such as HYDRAcap (NX Filtration), Litree..., integrated into Modules according to the requirements of each customer. products, projects. The module can be assembled in Vietnam, or imported raw from the manufacturer, depending on the customer's request.

SPECIFICATION

Hollow fiber membrane filter housing, PES (NX Filtration) or PVC / PVDF (litree) material. The average filter slit size is 0.01 micron (50000 Dalton).

Pumps, technology pipes, operating valves and electric controls are integrated on the Module, allowing easy connection to other items of the water purification system.

APPLICATION

Since the filtration capability is limited to filtration and handling of large solids (> 0.01 microns), Ultrafiltration (UF) Membrane Modules are not usually used alone in water treatment technology. It can be applied as the final stage of the treatment chain (in water treatment of buildings, hotels, resorts...) or as an intermediate stage (pre-treatment for RO water purification systems).
