Paper Mill Wastewater Treatment System

Paper Mill Wastewater Treatment System

Project Summary

A paper mill wastewater treatment facility uses diammonium phosphate to maintain a healthy microbial population. These microorganisms, which break down the organic matter, require the correct concentration of available phosphorus, without which the microorganisms are unable to grow and reproduce.

In an effort to reduce costs while maintaining the wastewater treatment plant’s efficiency, the mill replaced the DAP with Probiotic Solutions® SUPER PHOS®. The daily dose of SUPER PHOS® was 75 kg versus 600 kg per day of DAP.


Microbial Microscopical Examination


Replacing DAP with SUPER PHOS® reduced chemicals cost, the required storage space, and the cost of labor associated with moving and dosing the product. Treatment efficiency was maintained even with the significant reduction in the phosphorous dose. Effluent COD was maintained at 200 mg/L. Furthermore, a microscopic analysis of the sludge showed the microbiology to be more active and regrowth was more vigorous following the addition of SUPER PHOS®. In addition, by reducing the quantity of phosphorus being added to the system has reduced corrosion and deposits in pipelines further reducing operation and maintenance costs.

Product Summary

In response to the reactivity of phosphorous in wastewater, Probiotic Solutions® developed a phosphorous product scientifically complexed with Micro Carbon Technology®* called SUPER PHOS®. Over the years this product has proven to save money and improve plant performance by maximizing phosphorous bioavailability with minimum phosphorous input. SUPER PHOS® is an essential component of energy––carrying phosphate compounds (ATP & ADP), nucleic acids, several essential coenzymes, and phospholipids.

SUPER PHOS® starts out as white phosphoric acid that is pre-complexed with organic acids to ensure maximum availability to microorganisms. SUPER PHOS® has proven itself in wastewater applications where maximum performance is required and minimum effluent phosphorous concentrations are demanded.

* The base of all of our Probiotic Solutions® products and the secret to our high efficiency rates is Micro Carbon Technology®. It’s a proprietary blend of very small organic molecules that greatly enhance existing microbial activity in wastewater to reduce sludge, cut down on odor, and control BOD and COD levels.
