How to Treat Hard Water

09/23/2009 8:23 AM

One of our facilities in eastern Indiana employs well water for the manufacture of liquid dish detergents. The water hardness has changed gradually over the past year or so and is now quite hard at about 275 ppm. Not surprisingly, this is beginning to affect the performance of the end product as hardness would be expected to reduce detergency. Short of installing an expensive water softener to treat 80,000 to 100,000 pounds of water daily, would it suffice to add EDTA-sodium or something similar in a calculated amount to counteract this hardness problem? This is sometimes done anyway with cleaning products to enhance "softness" of a product. Thanks for any suggestions.

Add lime to increase your water pH to 10.5 to 11.0. This will precipitate out hardness. After precipitating out the hardness, bubble carbon dioxide gas through the water until the pH drops to 7.0. This will precipitate out any remaining dissolved calcium as insoluble calcium carbonate. You can then filter the softened water for use.

Hi miketheboilerguy,

GA to you Sir

For a good alternative choice to the first one of lime to make water with a higher PH.

Your System does work though I have only seen it once. I am surprised it is not fitted as standard?

I could certainly do with it where I live.

Take care.

Ah, Miketheboiler guy is on point. The previous post with the addition of lime would o the job. Asumming you have a large 100,000 gallon resevior holding the water when lime is to be added. This would also take some time to bind and fall out of solution.

That is the easy part, after it is nonsoulable and rests on the bottom you have to remove it. This requires pumps, bottom vaccume system, filter press or some means to remove the bound minerials from the water.

As Miketheboilerguy post the electronic WET2400

This technology can be used to bind the positive mineral to its oppisite ion where in line bag filtration could remove the majority. In the event you move to EDR membrane filtration, the WET2400 will keep the membrane film scale free for easy rinse of reject.

No Caustic or precleanning needed for EDR system.

KUDOS to the boiler guy.

Hi Anocholas,

You need to try one of Monsanto's product, called Dequest 2006. It requires a touch and the water is soft enough to be used for many occasions. Be careful using this very alcaline liquid, pH around 12 and higher. Also, this product cleans oily dirt. Good use of this product will help you as an excellent detergent, Gil.

Hi, I noticed no one has offered you a solution. The system you seek can be located at http://www.bdh-consulting.com/products.html

The WET2400 is the new product designed for many situations. This equipment is the cut and polished diamond from all the testing of parent equipment from around the world. The equipment is designed and programed by use of software to each water application's site analysis. There is one problem with the older designs, that were not smart enough. Some applications did work very well, others didn't, the diffrentence was the minerials in the water were at diffrent concentrations.

Give this 21st Century equipment a shot, I beleive you will be happy with the results. Finally, you can come back to this and other threads and give your positive testimony to all the other closed minded (claim to experts) engineers. Water analysis is required to pre set the controller for your situation.

Hello H20,

I think your post is a little unfair.

Please see post 1 and 3. Post # 1 mentions Lime and post # 3 mention WET.

Take care and no offence.

Edta would be the most efficient and economical way to treat the hardness in your water. We used edta in all of our formulae for dish and liquid laundry detergents. Our water tested over 300 ppm of Ca and Mg hardness.

THE NO SALT,NO CHEMICAL WATER TREATMENT ELECTRONIC DESCALER IS THE RIGHT ANSWER OF YOUR PROBLEM.IN CEBU CITY PHILIPPINES THE WATER HARDNESS OF WELL WATERS HERE WILL REACH 500 PPM.TO 650 PPM. CURRENTLY I HAVE FOUR INSTALLATION AND IT REALLY SOLVE THE ISSUE,..REMOVED SCALE BUILD-UP IN WATER HEATERS AND PIPES AND ON THE OTHER HAND IT PREVENTS TO FORM NEW SCALE FORMATION....BIG THANKS TO THE NEW EVOLUTION OF ENVIRONMENTAL FRIENDLY WATER CONDITIONING SYSYTEM,...I STRONGLY RECOMMEND " SCALEBLASTER" FROM CLEARWATER ENVIRO TECHNOLOGY..............
