Why do I need water treatment
Breakdown of utilities
Effective Water Treatment
Helps ensure safe & reliable system operation
Minimizes energy, water & maintenance costs
Maximizes life of a major capital investment
Poor Water Treatment
Increases liability concerns Results in downtime & production losses Increases labor & maintenance costs Increases energy & water costs Results in premature equipment replacement
Effective Water Treatment Requires a Comprehensive Approach
Technical Expertise
The Right Feed & Control Equipment
Quality Treatment Products
Service Orientation
Dedication to Meeting Individual Needs

Effects of Corrosion
Effects of Microbiological
Cycles of Concentration Any dissolved solids that were in the water are left behind
& concentrate in the remaining water Cycles reflect the degree makeup impurities are
concentrated in system water
1 Cycle
Makeup Total Dissolved Solids (TDS) = 100 ppm
2 Cycles 3 Cycles 4 Cycles
TDS = 200 ppm
TDS = 300 ppm
TDS = 400 ppm

Bleed or blowdown is the deliberate discharge of system water to maintain the desired cycles (dissolved solids level)

Importance of Cycles
Why Treat Closed Loops• Water and Metal don’t mix!
• The metal surfaces of your closed loop system are meant to last decades and they can if they are properly protected. A chilled water system line can last 40 – 50 years with proper treatment, but they can fail in as little as a couple years without treatment. Hot water system lines have been known to fail in the first year without treatment.
• Hot Water Systems can become scaled.• Calcium deposits can form on heating surfaces in areas with high hardness. Proper
treatment can prevent any scale formation.
• Anaerobic bacteria can destroy a closed loop system.• Even though the system is not exposed to sunlight or air, bacterial can still grow in it.
• Glycols are more corrosive than water by itself.• The corrosion rate of carbon steels and copper alloys in a 30% glycol solution is 10-15
times greater than in plain water.
