pH Water Treatment

Drinking Water Acidifier

Lower water pH without a bitter taste

As the strongest animal feed grade mineral acid available, PWT® requires a low addition rate to acidify drinking water to biologically effective low levels. The low addition rate allows water palatability to be maintained to promote optimum water consumption in birds and livestock. PWT poultry water treatment can also be used to manipulate pH in order to maximize chlorine effectiveness for waterline cleaning and sanitation.

Why Choose PWT - pH Water Treatment

PWT (sodium bisulfate) is the most widely used and proven effective mineral acid on the market. As an FDA-approved GRAS product that also qualifies for use in EPA Safer Choice-labeled products, PWT is effective, safe, and suitable for use in antibiotic-free and conventional production programs.

Maintain Palatability to Optimize Consumption

Due to its strength, PWT is able to lower water pH at a low addition rate so water is acidified without imparting a bitter taste. Birds prefer water at this low pH, which optimizes water consumption.

Low Addition Rate Means Greater Value

PWT is a dry, granular acid that is easy to mix and effective at a low addition rate, which saves money.

Maximize Chlorine Efficacy

By reducing pH, PWT works to maximize the efficacy of chlorine. When used to clean waterlines between flocks, the product helps dissolve lime and scale to restore and maintain full function of waterlines for optimum flow.

PWT Frequently Asked Questions

Addition Rate

How Much PWT Is Too Much?

The pH of the drinking water should not go below a pH of 3.0.

How Do I Decide What Rate To Use?

Two factors determine how much PWT is needed on a given farm: end-use of PWT (crop acidification or chlorine management) and characteristics of the water source (pH and alkalinity). Refer to the rate chart for the appropriate amount in each situation.

Product Use

Is PWT approved for animal consumption?

Yes. PWT is approved by the FDA as an animal feed additive.

What is the difference between PWT and citric acid or vinegar?

PWT is a strong, mineral acid while citric acid and vinegar are weak organic acids. PWT has a low addition rate and a pleasing taste to birds while organic acids such as citric acid taste bitter causing birds to reduce water consumption.

How long should I run LS-PWT?

LS-PWT2 should be run for the first 7-10 days the birds are placed in the house, around feed changes, and prior to processing. More information about usage for different types of birds can be found here.

I have never run PWT before. Is it ok to run it mid-flock?

If you have never used PWT before, it is recommended to use it for the first time while the house is empty.

Because PWT cleans the water lines so thoroughly, dislodging lots of biofilm and residual material in the lines, a high pressure flush is needed to remove that debris from the water lines.

Using PWT with birds in the house for the first time will make it difficult to remove all of the debris dislodged by the cleaning process possibly causing clogged nipples and birds to ingest the dirty material.

Do I need to make fresh solution everyday?

No. Unlike antibiotics and other water additives, PWT is very stable when mixed. A stock solution of PWT will maintain its potency for at least 30 days.
Water Chemistry

What is pH?

pH is the measure of the number of hydrogen ions in solution. The more hydrogen ions in a solution, the lower the pH will be.

Will birds drink water at a low pH of 3.5?

Yes, if it is acidified with a mineral acid such as PWT. Because mineral acids easily donate hydrogen ions into a solution, they have a low addition rate and a pleasing taste to birds.

Is alkalinity important when testing water?

Yes. Alkalinity is a measure of the carbonates in a water source that will bind to the PWT or any water acidifier. Only after all of the carbonates in the water are bound by the PWT will the pH begin to drop. The higher the alkalinity of a water source, the more PWT or any other acid will be needed to reach the target pH.

How do I properly test water to determine addition rate of PWT?

A sample of the water can be taken either at the well or at the entrance to the house. A pool test kit or test strips can be used to determine the pH and alkalinity of the water source. Once that is known, use the chart below to determine addition rate.
Waterline Cleaning

How long should I leave PWT in the lines when I clean between flocks?

The first time you use PWT in a house for cleaning, it should only be left in the lines about 8 hours due to the large amounts of debris that is removed during the cleaning process. This will facilitate the removal of this gelatinous material from the drinker system. After PWT has been used to clean the drinker system, then it can be left in the lines as long as 24 hours prior to flushing.

How often should I clean my drinkers?

At the end of every flock and after running any type of water additive such as electrolytes or vitamins.

Should PWT be run after I use electrolytes or vitamins?

Yes. This will remove any residual material from the water additives that can be a food source for bacteria

Will PWT clog my drinker lines?

No. It is the debris being dislodged from the dirty drinker system that could possible clog the lines if it isn’t flushed out promptly and thoroughly.
