Improve Quality with Good Maintenance Procedures

Common problems and prevention/troubleshooting tips

Plugging

• Very common with use of reclaimed or white water
• Nozzles, lines and shower can plug due to debris and long fibers in the water
• Use proper water clarification devices
• Use strainers
• Be sure to specify nozzles with adequate free passage
• Conduct maintenance on a regular basis
• Use automated self-cleaning showers

Corrosion

• Many chemicals are extremely corrosive
• Specify nozzles in the appropriate materials: 316 or 304 stainless steel depending on chemical concentration. Avoid iron and mild steel

Scale Build-Up

• Control hardness level of the water
• Use chemical additives as needed
• Conduct maintenance on a regular basis

Slime and Odor

• Implement an effective biocide program to control biological growth
• Use chemical additives as needed
• Eliminate areas with stagnant water
• Conduct frequent wash-ups

Caking

• Build-up can occur inside the nozzle or on the exterior
• Conduct maintenance on a regular basis

Value of good maintenance procedures

If you neglect your nozzles, you’ll watch your energy, water and chemical costs increase. Even slight wear can cost tens of thousands of dollars annually in creased operating expenses. Assess your operations and determine maintenance frequency needed to preserve product or process quality. Good maintenance is an easy and inexpensive way to ensure optimal spray system performance.
