Uses Soda Ash in the briquette form facilitates the use and handling of Soda Ash. The primary use of
Soda Ash Briquettes is for Acid Neutralization in industrial settings. Examples of which would be
wastewater treatment and coal mining acid drainage water treatment. In treating acid mine drainage water,
the soda ash briquettes are generally placed in a plywood or fiberglass feeder box where the flow of the
acid drainage water, through the bottom of the feeder box, dissolves the briquettes which neutralizes the
acidity in the drainage water. The drainage water usually has an initial pH range of 3.0 - 5.5. Soda Ash
briquette treatment usually increases the pH range to the range of 7.0 - 9.0. The upper end of the pH range
is usually desired if the drainage water is blended with other drainage water where the pH may be below
neutral lever of pH 7.0. Soda Ash briquettes are also used as a flux of desulfurizer in the foundry industry
and for pH and alkalinity control in swimming pools.
Packaging Briquettes are packaged in 25 lb. or 50 lb. net multi-wall. plastic lined paper bags or 50
lb. net polyethylene bags and are palletized 50 bags per pallet (84 on 25 lb. bags). Special 25 kg. (55 lb.)
multiwalled paper bags are also available.
