Brockway, Pennsylvania-based Prochemtech has develped a process for removing pollutants from frac water. Working with Centre Hall-based Nittany Engineering Associates, Prochemtech has developed a patent-pending process which removes the highly toxic barium from the frac water as well as the scale forming minerals. This allows recycling of the water for additional hydro-fracturing.

The barium is precipitated out of the frac water by adding a sulfate to it which combines with the barium to create barium sulfate "chunks". These chunks are insoluble and non-toxic, and can then be removed from the water.

Calcium, iron, magnesium, manganese, and strontium are then precipitated out by reacting them with carbonates and hydroxides.

Tim Keister is Chief Chemist and President of the company.
