Water costs can send your shop’s bottom line down the drain if not managed strategically.
From cutting fluids and washwater to rinse tanks and even floor scrubbers, industrial process water circulates throughout the facility. But without a sound management strategy, process water can become a costly liability. As environmental regulations become stricter and haul-away costs skyrocket, managing water has become a critical consideration.
Inefficient Water Management Has a (Steep) Price
The cost of disposing of hazardous fluids can be staggering. For high-volume manufacturers, this number could easily run into the hundreds of thousands of dollars every year.
At PRAB, we know that managing water isn’t only about improving your process or maintaining compliance—it’s about staying profitable.
By optimizing your industrial process water, you can turn a costly waste stream into a reusable, valuable asset, helping your shop cut expenses and stay compliant and efficient.
If you’re facing challenges with water use, you’re not alone. Every metalworking shop deals with them. But those challenges are also opportunities for big efficiency improvements.
Here are some common process water problems and how we’ve implemented the right PRAB systems at different points of the process to address them.
Problem 1: High Volume of Oily Wastewater and Excessive Haul-Away Fees
Large volumes of oily water from parts washers and machining centers can result in exorbitant disposal costs.
Problem 2: Contaminated Vibratory and Tumbling Deburring Water
Vibratory finishing creates a slurry of metal fines and particles that fouls water and ruins part finishes.
Problem 3: Fluctuating Wastewater pH and Heavy Metals
Inconsistent chemical use during cleaning can cause pH spikes and metal contamination, damaging municipal infrastructure and resulting in heavy regulatory fines.
Problem 4: Scale Buildup and Reduced Coolant Performance
Hard water minerals react with coolant concentrates, causing scale buildup on machines and tools.
If efficiency and cost savings are the goal, metalworking operations must implement the right equipment for specific applications to reclaim water and improve profitability. Key systems that help serve this function include:
Ultrafiltration uses a pressure-driven process to separate emulsified oils and suspended solids from water. This is a tried-and-true method for treating washwater, rinsewater, and floor scrubber waste.
Reverse Osmosis units are counted on when high-purity water is required for coolant make-up or sensitive rinsing. The unit presses feedwater through a semipermeable membrane to remove dissolved salts and minerals.

Continuously monitor and regulate your water’s pH in real time with an automated pH Adjustment System that delivers the consistency needed for effective water management.
Designed to remove free and mechanically dispersed oils, these systems are often the first line of defense against downstream equipment damage.
For facilities aiming for Zero Liquid Discharge (ZLD), vacuum evaporation is an ideal solution. These systems boil water under a vacuum to distill clean water from contaminated waste streams.
The Bottom Line
Managing your process water is a strategic business decision that brings numerous cost and resource savings. Whether you are dealing with vibratory finishing slurry or high-volume washwater, the data is clear: optimizing your water usage leads to a safer shop, an improved finished product, and a significantly stronger bottom line.
