PHILOS is an R&D-focused membrane manufacturing company that has produced various kinds of membrane-related products and systems for almost two decades. It carries a long experience in providing solutions for the water treatment industry as until now, PHILOS has mainly focused on MBR and UF membranes for wastewater treatment, water treatment, separation, and concentration respectively. Not only limited to the water, but PHILOS has currently developed and is producing air dehumidification and humidifiers for hydrogen fuel cells, as wells as membrane bio-reactors for cell culture. In addition, PHILOS also produces systems related to the R&D and production of membranes. All in all, PHILOS strives to provide its customers with a total solution related to the membrane.


Our History

PHILOS was founded in Korea in 2002. In the early days of its founding, it has mainly focused on research equipment related to membranes. From 2004, membrane development and production began. PHILOS commercialized composite membrane using braid as a support for the first time in Korea. In 2004, PHILOS was selected as a “technology innovation company” by the Korean government. Since 2006, PHILOS has become a subsidiary of Korea Water Purification Industry, the number one water company in Korea, and has commercialized and widely distributed membranes suitable for pure water production, water reuse, and seawater desalination of power plants. In 2012, PHILOS separated from Korea Water Purification Industry and started a new leap forward. Now it has grown into a company specializing in membrane materials and systems.

Our Products

PHILOS's products can be classified into three categories; membranes, membrane manufacturing systems, and consumer products. PHILOS produces state-of-the-art technology and design for all of its products. In the case of membrane products, we provide Hollow fiber MBR and UF membrane for water treatment and wastewater treatment. Similarly, we also offer a dehumidification membrane for controlling air humidity, a humidifier membrane for fuel cells, and a bio-reactor for cell culture. Likewise, PHILOS also offers pure water purifiers and containerized systems for water and wastewater treatment. In addition, PHILOS is also actively working on developing research devices that manufacture and evaluate the performance of both hollow fiber and flat sheet type membranes. On the other hand, PHILOS's daughter company, Wellspring is working on providing portable water purifiers, long-term disinfectant coating agents, enzyme sanitizers, and SC (Supercapacitor) batteries. Moreover, It also provides and supports water purification systems related to appropriate technology for underserved communities around the world.


Our Vision

The vision of PHILOS is to become a specialized company in membrane development society by producing and providing total solutions for membrane technology. We envision providing not only world-class membrane module products but also membrane development systems that possess advanced technology and design to solve the problems related to air and water fields. In addition, through our technology and business, we aim to provide appropriate technologies to people around the world including underserved communities so that they can lead a quality life with happiness and satisfaction. 


Our Technology and Core Strength

Founder of PHILOS Dr. Jeong-Hak Kim has been researching membrane manufacturing for 40 years since 1982. He is the first in Korea to commercialize membranes. Therefore, until now, PHILOS has been developing and commercializing various membranes for 20 years. Moreover, PHILOS also has many ideas for the new fields in separation technology. It also holds 50 patents related to membrane manufacturing and application with more than 1000 references in membrane and system installations.  So far, more than 20 government-sponsored projects have been successfully carried out as well. The core strength of PHILOS is, above all the “diverse experience, creativity and knowledge in membrane technology”. PHILOS has already had enough of experiences in this field, so many of our customers have mentioned about having a pleasure working with us.
