Sodium Carbonate (Na2CO3), usually known as Soda Ash, is commonly used in water treatment to increase the pH of acidic water.  Soda ash systems are employed to act as first a pH adjuster with the added benefit of softening of the water.  The carbonate ion is utilized to precipitate out the hardness in water. The primary advantage to using soda ash is that it acts as a water softener, since carbonate can precipitate the calcium and magnesium ions present in "hard" water.  

These systems normally include:

  • Storage Silo – Sizes range from 8’-0” up to 15’-0” in diameter.  Shipping regulations and obstacles determine the limit of the overall width, height and weight of shipments.  Factory assembled systems can be shipped as one piece or in sections depending on silo height.

  • Storage Silo (field welded) - Sizes range from 16'-0'' to 36'-0'' in diameter.  Partially assembled parts, rolled plate and steel structure are shipped to the construction site on standard flat bed trailers.

  • Pneumatic Silo-fill pipe and NEMA 4X operator station.

  • Dry product level monitoring devices.  Continuous level and/or point level indication device(s) are available.

  • Roof-mounted dust collector (bin vent).

  • Roof-mounted dehumidifier.

  • Bin activator or vibrators.

  • Rotary lump breaker.

  • Volumetric screw feeder with inverter-duty drive motor and variable frequency drive.

  • Solution make-down/storage tank complete with all level monitoring devices, agitator, required nozzles, and dust and vapor (D&V) removal system.

  • Feed pumps as specified.

  • All piping, valves and instrumentation.

  • Local system control panel complete with programmable logic controller (PLC) including pre-programmed system logic.  All systems are factory tested to the greatest possible extent before leaving the factory. 

  • Silo systems are provided with ventilation fans, heaters and lighting.  Silo skirted interior is insulated.
