Ozone water filtration problems in Panel plant (chemical resistance and flow rate)

Company D is a global LCD panel company with several product lines, such as covering 6th generation line, 8.5 generation line, etc. It has several production bases in Taiwan and mainland China.

During the contact with Company D, our salesman found that in order to increase the flow rate of washing water, the customer rushed into the ozone water at the process node, causing the filter core used by the customer to be corroded within 2 days.

After understanding the problem, our company immediately communicated with the customer and sent a technical team to visit. It was learned that the corrosion-resistant PTFE material could not meet the flow rate requirement. Although PES can meet the flow rate requirement but is not resistant to corrosion.

Therefore, our company had proposed a high-throughput, high-blocking, corrosion-resistant product (nano PVDF material) as a solution. After the customer compared, he thought we could try it out.

As a result, our filter element did not detect corrosion for one month after ensuring flux and interception rate, and the customer’s product yield also met the requirements. The customer was very satisfied with the verification results and quickly reached the supply agreement for the filter element.

The result is that our filters have been used for a month and weren’t detected any corrosion on the premise of meeting all the requirements.

The customer was very satisfied with the verification results and quickly reached a supplier agreement for the filters.
