Dolphin Water Treatment?

Our company is constructing a new facility and the Mechanical contractor is trying to push the Dolphin Water Treatment System to us. I have one contractor that has worked with it and wasn't to impressed but the facility doesn't have regular scheduled maintenance on the system( put it in and forget it). Anyone work with the system before have any pro or con comments? I've always worked with chemical treatment and find it good can't find a reason to swith from what we know works

    Could U clarify to us what is the Dolphin Water Treatment system?

    Is it a new method / new way to treat the waste water?

  • In reply to thekatyusha:

      The Dolphin Water Treatment is used in cooling towers.  It send an electric charge through the water as it is pumped through the tower.  this eliminates scale build up and won't allow susppended particles to attatch to coils.  This is what it claims, I remember claims of magnetic rods that would do the same but never heard of anyone bragging of the method.

    tdiver,

    Sorry, but these "electric" or "magnetic" water treatment schemes are just that....a scheme.  They aren't supported by any credible agency, academic or industry findings.

    You didn't say whether or not your cooling tower was an open or closed design, but it's best to stay with reputable industrial water treatment companies.  The type of treatment you will need depends on the design and the quality of the make up, type of piping, general geographic location, etc.

    A professional water treatment company can help you answer these and other questions.

     

     

  • There is no reason to switch from chemical treatment, your water needs to be chemicaly treated.  Dolphin system does not change the hardness, only makes water feel softer.  Thus still causing cooling towers and piping to form major scale build up and costing thousands of dollars in repairs to pumps and valves.  Take it from someone who had installed both systems and seen the results first hand.  Your company is better off spending the time and money with a chemical treatment system that works. 

  • Take my advice, run do not walk, away from the Dolphin System as fast and as far as you can.  My company has been approached on different occassions by vendors offering non-chemical treatment systems.  We even tried one early on.  I don't remember the name but is was a magnetic system designed to strap on the pipe and generate a magnetic field to keep solids from attaching to the piping.  The scale that was created during use is unbelieveable and we found out later that the supplier went out of business very shortly after installation.  Probably having changed their name to better prey upon another unsuspecting company.  A properly maintained chemically treated system does not have to cost a lot.  We have managed to reduce our expenses through training staff to conduct more frequent tests and repairing water leaks when ever they occur.

    We had a 1950 Hospital that had use chemicals most of its life. The last five years I switched to the Dolphin System. I have pictures of before and after. The system dose as the say but their are pros and cons. Pros: We had less equipment failure (Traps, Leaks) with the system. Did not worry about hard water so tube leaks were not a problem. Being in a old building that was a big deal to enclude Traps. The Cons: you use more water, change the bottum tubes almost yearly due to leaks, Weld all tubes to keep from leaking. We had boilers that you could alternate so they would cool down when they were off. I talk to a Navy Hosptial and they say it the best system they have ever seen. They keep all of their boilers hot so they never get cold. And they change tubes yearly.
