국가물산업클러스터 사업단이 ‘해외현지 성능평가’를 앞세워 입주 중소기업들의 해외판로를 개척하고 있다. 우수한 기술을 보유하고도 해외 판로개척에 어려움을 겪는 기업을 발굴한다. 실증화 플랜트에서 제품 성능을 검증하고 그 결과를 해외 수요처에 제공해 신뢰성을 높여 ‘제3자 성능검증’을 진행한다.
Water companies such as CJK and ARK were selected for overseas local performance evaluation through expert evaluation following open recruitment in 2022 and last year.
사업단은 CJK와 ‘리튬배터리 양극제 제조공정 엔-메틸 피롤리돈(NMP) 리커버리 패키지 역삼투압(RO)시스템 최적화’ 과제를 수행했다. 약품주입 최적화를 통한 분리막 회수율 증가, 오염방지 및 세정 최적화, 마이크로 버블 세정장치를 이용한 RO모듈 우수 세정효과 발현을 목표로 한다.
In consideration of Hungary's inflow water quality, which has a higher hardness than Korea's, the optimization system that increases the RO operating recovery rate from 601 TP3T to 701 TP3T by injecting scale inhibiting chemicals and reduces the amount of wastewater generated by more than 101 TP3T, and the technology that reduces the amount of wastewater and waste generated using micro bubbles were verified locally. The company signed a contract worth 5.5 billion won in the year of performance verification, and is expected to expand sales in overseas markets such as the United States and Canada through participation in the global water industry expo Aquatec.
“To expand our export market, we have hired 13 new employees to create both sales and jobs,” said Kim Sang-wook, CEO of CJK.
클러스터 사업단은 에이알케이와 ‘슬러지 처리용 Decantercentrifuge 개발’ 과제에서도 실질적 성과를 냈다.
The product was modified to increase the contact area between sludge and flocculant by using an inlet pipe type dehydrator with protrusions to facilitate mixing. As a result, the amount of flocculant injected was reduced and the moisture content of the dehydration cake was lowered due to less flocculant residue inside the dehydration cake, resulting in a product with higher dehydration efficiency. The cost of chemicals was reduced by more than 301 TP3T, and piping and installation costs were also reduced. It was manufactured to reduce noise and vibration even at high speeds, and was contracted and installed at the Song Da and Hue water treatment plants in Vietnam, worth about 1 billion won.
“We are operating a decanter centrifuge test vehicle in Vietnam, and based on Vietnam, we are promoting the expansion of dehydrator installation in emerging developing countries such as Malaysia,” said Hong Sang-heon, CEO of ARK. “We will participate in European environmental exhibitions such as IFAT in the future to provide a market for our excellent technology.”.
