Worksite Improvement Case Studies

Semiconductor and precision instrument workplaces

Hoses for discharging chemical waste degrade quickly, requiring frequent replacement.

At a factory producing printed boards, the effluent had to be brought to a certain pH level in the discharge process to prevent water pollution. Their process involved injecting sulfuric acid, hydrochloric acid and sodium hydroxide to adjust the pH level. This caused their PVC hoses to become brittle and otherwise degrade quickly. Because they needed the hoses to be flexible, they had to replace the hoses frequently.

They used the long-lasting flexible TOYOFUSSO SOFT, which is chemical resistant, and cut down on replacement frequency. Problem solved!
