[Visit the National Product Industry Cluster] [3] ’Overseas Local Performance Evaluation' Opens Export Markets for Chinese Companies
The National Water Industry Cluster is pioneering overseas sales for resident SMEs through the ‘Overseas Local Performance Evaluation‘ program. It identifies companies that have excellent technologies but have difficulties in developing overseas sales. It verifies product performance at the demonstration plant and provides the results to overseas customers to enhance reliability and conduct 'third-party performance verification'.
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.
The project, ‘Optimization of Reverse Osmosis (RO) System for N-Methyl Pyrrolidone (NMP) Recovery Package for Lithium Battery Anode Manufacturing Process,’ was conducted with CJK. The project aims to increase the recovery rate of separator membrane through optimization of chemical injection, optimize pollution prevention and cleaning, and express excellent cleaning effect of RO module using micro bubble cleaning device.
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.
The cluster has partnered with RK to create a ‘sludge treatment Decanter centrifuge Development’ challenge also made real progress.
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 centrifugal dehydrator 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.”.
