Recruitment Information

  • Our business portfolio includes design, manufacturing, sales engineering and quality management (including after-sales service) of water treatment membrane modulesystems incorporating our proprietary PTFE filtration membranes.
  • Overseas customers, mostly in Asia, account for almost all our clients.
  • PTFE membranes are superior in strength, heat resistance and chemical resistance to membranes made from other materials. They are exceptionally effective for wastewater treatment under severe conditions, contaminated with oil and high levels of other contaminants discharged from petrochemical plants and oilfields. Our goal is to make PTFE membranes the standard in the wastewater treatment field.

  • Graduates in electrical/mechanical engineering or chemistry preferred
  • Experience in the water treatment business
  • Personnel assignment is slow in comparison with our business growth. We welcome people who are enthusiastic and have the determination to outperform our strongest competitors, making the most of the product's advantages.

  • The work involves negotiation with and presentation to overseas customers.
