Improving the working environment by dewatering waste dry film photoresist

Semiconductor package manufacturing plant

At this plant, waste dry film photoresist containing a lot of liquid was manually put into drums for disposal. Because dry film photoresist is highly alkaline, it is dangerous to carry and dispose of it. The company was looking for a way to improve the working environment by removing the liquid from the dry film photoresist for ease of handling.

Succeeded in stable supply of polymer to two equipment from one Polymer Make-up System

Meat Processing Factory

This customer was newly proceeding with a plan for installing a wastewater treatment plant. As the wastewater discharged from the factory contained much oil, the customer was planning to install a dissolved air flotation system in the wastewater treatment process. The VOLUTE™ Dewatering Press, having strong resistance against oil, was considered for dewatering of the sludge. We immediately tested the sample sludge and found that two types of polymer of both cationic and anionic polymer were needed to dewater the sludge. This means three Polymer Make-up Systems would be necessary; two for the sludge dewatering press and one for the dissolved air flotation system.
