EPS MOLDING - STEAM SYSTEM & COOLING WATER TREATMENT RESULTS

The EPS molding facility in Lower Mainland was using phosphate based chemistry for steam boilers water treatment and sodium hypochlorite for cooling water treatment. Due to scale build-up on boiler tubes, they were also using an online cleaning chemical to remove the deposits. 

Another major problem was severe biological growth in the cooling water which required frequent cleaning of strainers to maintain cooling water flow. Bio-film formation also increased iron level in cooling water due to microbiological induced corrosion (MIC).

Since 2005, our treatment program has delivered following results:

1. Installation of automatic controls for blow-down and chemical feed has helped us improve the efficiency of steam system by optimizing make-up water and chemical usage. Boiler inspections for last 3 years show reduction of previous deposits and excellent overall condition.

2. Steam boiler make-up water usage per cycle has reduced by 20%.

3. Chemical cost for boiler water treatment per cycle has decreased by 35% as compared to the previous supplier.

4. Natural gas usage per cycle has reduced due to reduction in make-up water usage leading to savings of $20,000.00 per year.

5. Adding a passivating amine to treatment program has reduced iron level in condensate from 1 – 2 ppm to less than 0.1 ppm.

6. Ozonation system (rather than hypochlorite) as cooling water treatment has dramatically improved cooling water quality by controlling biological growth. It has also reduced iron level in cooling water from 3 - 4 ppm to 0.1 ppm.

7. Shift engineers spent 15 minutes every 2 hours cleaning all cooling water strainers in the plant due to slime build-up. The frequency has reduced to once per shift leading to significant savings in man-hours and improved efficiency.   

In conclusion, we have been able to improve the efficiency of steam boiler & cooling system and reduce treatment cost for steam boilers & cooling system.
