TVTS is the exclusive representative and distributor of ROCHEM RO membrane technology in Vietnam.

1. Introduction to ROCHEM RO membrane technology

The RO ROCHEM brand is an industrial RO membrane product of the ROCHEM Group, Germany. A look at the development of RO ROCHEM membrane technology over time:

• 1973 – RO-ROCHEM membrane was born and provided a solution for seawater treatment for the navy
• 1886 – Research and development of PFRO module
• 1989 – Using PFRO technology to remove impurities in leachate has been widely applied worldwide
• 1992 – Widely serving the navy with PFRO desalination module
• 1999 – Achieved ISO 9001 certification
• 2001 – Pioneered the direction of wastewater treatment difficult for reuse
• 2005 – Developed STRO module to increase the amount of water recovered for the treatment process
• 2014 – Developed TSRO technology for water treatment to improve recovery efficiency on each module

3. Fields of application and applications

Most of Rochem RO membrane systems are being applied to thoroughly treat difficult wastewater. This type of water contains high levels of COD, BOD, Nitrogen, Ammonium… for industries such as: Landfill; Distillation; Pharmaceutical; Textile and dyeing; Pesticide production; Chemical waste treatment; Nuclear….

RO Frame-Disc membrane evaluation clearly outperforms other methods such as evaporation and secondary treatment. Rochem RO membrane system confidently brings high economic efficiency in the fields of:

• RO membrane is specialized for reusing textile wastewater.
• Application for treatment and reuse of leachate, landfill wastewater, landfill.
• Treatment and recirculation of pharmaceutical wastewater
• Treatment of food wastewater
• Treatment and recirculation of electroplating wastewater
• Treatment of hazardous wastewater
• Treatment of difficult industrial wastewater

4. Description of ROCHEM industrial membrane technology characteristics

The material rejection capacity of the RO membrane is in the range of 0.0001 to 0.001 µm. And the ROCHEM RO membrane is constructed with a membrane pore size of 0.0001 µm. With this size, only water molecules are allowed to pass through.

4.1 Hệ thống màng RO Rochem – Đức

Rochem RO Membrane Module System – Germany is provided by TVTS. It is a system designed based on membrane technology specialized for treating difficult wastewater. With an open channel design, the system allows the system to separate waste streams with very high COD and BOD without encountering clogging problems like conventional RO membrane filtration systems. Rochem RO Module is a unique module line in the world with a design that is highly resistant to membrane clogging. Rochem RO membrane systems have been used worldwide for over 3 decades. Of which, a large number of systems are operating with wastewater with COD and BOD levels up to 140,000 ppm. We are confident to be the leading supplier of reverse osmosis filtration systems with difficult wastewater treatment requirements, with high pollution levels. The system also allows the treatment of seawater into fresh water. Serving on warships, submarines, drilling rigs, passenger ships and commercial ships to provide clean water.

4.2 Basic advantages of Rochem membrane technology

• Limit clogging.
• The quality of treated water always meets the discharge and reuse standards.
• The technology has been proven effective worldwide.
• Can treat wastewater containing very high levels of COD, BOD, Nitrogen, and Ammonium.
• Ensures optimal operating costs, low total operating costs for the entire product life cycle.
• Long membrane life.
• Total investment and operating costs are lower than traditional treatment systems with the same flow rate.

ROCHEM’s RO membrane module uses a specialized Reverse osmosis membrane for wastewater filtration. The difference between ROCHEM’s RO membrane module and other RO membranes is due to the tube module structure design combined with open channels and vortex flow.
