JOEUN ENVIRONMENT (www.rcf.kr) participated in 'ECO EXPO(www.ecoexpo.or.kr)', a cyber ECO Expo and showcased RCF (ROLL CONTROL FILTER) System.

'RCF (ROLL CONTROL FILTER) System' is a filer upgraded from existing one. Cleaning amount is innovatively reduced so filtration time can be lasted for a long time.

In addition, filter fibers are coiled around filter drum as roll type, so suspended solids are filtered by passing this filter drum from outside to inside.

Meanwhile, 'ECO EXPO', an innovative online eco expo supervised by Ministry of Environment and hosted by Korea Environmental Industry&Technology Institute, supports overseas market entry and promotes superior technologies and products of Domestic environment companies. They make digital contents for promotion by participating in ENVEX 2012 (The 34th international exhibition on environment technology & green energy) held June 11-14 for four days.
