Technical Discussion: New Technologies for Circulating Cooling Water Treatment (Biological Enzymes)
Thread Content
This post was last edited by hesonchang214 on 2011-6-18 at 18:51. New technologies for circulating cooling water treatment make use of natural biological enzymes: protein-degrading enzymes, grease-degrading enzymes, fiber-degrading enzymes, as well as hydrolytic and oxidizing enzymes, to naturally regulate water quality and achieve the optimal balance within the system! Differences from traditional chemical agents: 1) Easy to purchase. This product is a biologically-based agent that combines corrosion inhibition, scale prevention, and sterilization in one – it is non-toxic, harmless, and does not cause secondary pollution! 2) Easy to manage. Add it once every one to two months. The addition amount is 0.002% to 0.005% of the retained water content. Just add the chemical directly to the collection tank! 3) Low operating costs. It saves about 20% on operating costs compared to traditional chemical agents. High concentration ratio! Effect of use: 1) Areas severely affected by bacteria and algae will continue to be decomposed until the old dirt is completely removed ； 2) The sediment at the bottom of the water tray begins to decrease until it is completely decomposed ； 3) Capable of operating normally at high concentration ratios ； 4) The pH value will be maintained within the slightly alkaline range (7.5~8.5) ； 5) The growth of bacteria and algae on the heat sink plates, tube walls, and water pans is suppressed. 6) Maintain water clarity through continuous control, significantly reducing wastewater discharge ； 7) Continuous use will improve the operating efficiency of the host and reduce power consumption ； If you, esteemed engineers, are interested, you can try it out for free at this factory! You can send me a message inside the site again! Please include your power plant’s full name and contact information!

Not bad! Saved! Thanks for your hard work, OP!

Reply to 2# houmeihong11: We have been using it at a steel plant in Gansu for a year now; it is safe, reliable, and the system remains stable. The concentration factor can reach up to 11.6 times. However, after calculations, manufacturers find that a concentration ratio of 6 to 8 times offers the best cost-performance ratio! The unit price is quite high; it involves eight years of R&D and a high level of technology, with a cost of over hundreds of thousands per ton. But the most conservative guarantee we can give you is 1) it will not be inferior to chemical agents. 2) The operating costs are lower compared to chemical agents, and the operation and management are simple. I wonder what the annual operating costs are for your factory? And what is the water retention capacity?

In the recirculating water system, before adding biological enzyme agents: pH, turbidity, conductivity, TDS, iron, total phosphorus; concentration ratio. September 10: 8.45, 132, 2910, 1483, 1.62, 1.72, 1.0. September 13: 8.44, 120, 2080, 1034, 2.03, 2.62, 1.28. Water quality parameters after adding biological enzyme water stabilizers: September 25: 8.8, 160, 1798, 897, 0.89, 1.9, 1.2. September 28: 8.18, 93.6, 2250, 1135, 0.75, 1.59, 1.4. October 12: 8.78, 91.2, 2080, 1188, 0.84, 1.9, 3.2. October 19: 8.74, 84.8, 1722, 954, 0.49, 1.85, 5.9. October 26: 8.08, 56.3, 557, 244, 0.34, 1.21, 8.7. November 3: 8.41, 34.9, 363, 280, 0.53, 1.52, 9.4. November 9: 8.52, 13.7, 468, 267, 0.49, 1.34, 9.8. November 16: 7.41, 6.52, 584, 265, 0.54, 0.95, 10. November 23: 8.4, 12.6, 584, 309, 0.49, 0.97, 10.2. December 2: 7.92, 13.5, 768, 347, 0.43, 0.91, 10.8. December 8: 7.97, 18.7, 714, 340, 0.42, 0.86, 11.5. December 15: 8.08, 11.6, 668, 352, 0.46, 0.87, 11.9. Finally, the plant chose a concentration ratio of 6 to 8 times as the most cost-effective option for its needs!
Regarding new technologies, I hope all the senior engineers will share their opinions!
I’m in the same field and aim to learn more. I have some questions regarding your approach to handling this issue: 1. Is it similar to the chemical treatment method, where biological enzymes are added regularly to the circulating water? Should they be used in combination with chemical agents? 2. Could you explain the principle behind this treatment? My understanding is that the main components of scale are calcium carbonate and magnesium hydroxide, both of which are inorganic substances. How do the biological enzymes you mention act on these scales, and how is the hard scale removed from the system? Through what means is it removed from the circulating water? 3. My original understanding was that biological enzymes are used to break down organic substances; for example, some laundry detergents work very well at breaking down protein-containing stains. Is there any essential difference between biological enzymes and traditional enzymes? What about factors such as temperature and pH, enzyme specificity, and whether these enzymes can undergo structural changes? 4. As a reference for determining the dosage you use, what criteria are used to decide the dosage of your biological enzymes? I won’t ask about the cost of treatment
