Bagless recycling: General Industry Coverage

When operating a waterjet machine, the cutting water typically goes down the drain. However, water recycling systems can virtually eliminate this water loss, according to Benjie Massara, marketing director for WARDJet Inc. One problem is that traditional systems that filter workpiece particles and abrasive materials have a high operating cost because they consume large quantities of filter bags and include a deionization process, he added.

Therefore, machine builder WARDJet introduced the WRS-3000 modular system to recycle water without using filter bags and make deionization optional.

The recycling process begins by removing particles larger than 10µm through a multimedia filter. “The water runs through a number of different media without using something that’s consumable,” Massara said, noting that users recharge the multimedia filter every year or two by adding media material, such as anthracite.

The WRS-3000 modular system from WARDJet recycles water from a waterjet cutting machine without using filter bags.

He added that the waste that’s removed contains no excess water, making waste disposal easy. “We have the system running on our floor and we’re reclaiming more than 85 percent of our water on average,” Massara said.

After the 10μm particles are removed, the water flows through a bank of four filters, removing particles from 5µm to 0.2µm in size.
