TWT NON-CHEMICAL TREATMENT FOR WASTEWATER
Application Triangular Wave Technologies Benefits
Chlorine Injection Pumps
Pump deposits Often pumps used to feed chlorine into the treatment stream become full of scale and must be cleaned.  Triangular Wave Deposit Control systems keep the scale particles suspended in the fluid and off of the pump surfaces.
Nitrate / Nitrite Removal
Resin Bed Triangular Wave Deposit Control systems keep calcium carbonate ions in solution, prevent the calcification of the resin bed, and the formation of channels in the bed that leads to ineffective treatment.
Pumps, filters, and sensors Triangular Wave Deposit Control systems keep the scale particles suspended in the fluid and off of the equipment surfaces.
Downstream of removal system Triangular Wave Deposit Control systems will protect the discharge line, keeping it free of scale caused by heavy concentrations of calcium carbonate.
Lime or Soda Ash Treatment Soda ash is the most commonly used treatment for low pH in wastewater streams; inexpensive, safe, and able to be sewered without EPA concern, it is actually also raw, uninhibited scale!
Mixing tank Using lime to treat high pH water or soda ash to treat low pH water present some of the greatest scale control challenges.  The lime or soda ash is mixed with water to form a slurry that is then pumped into the water to be treated.

The mixing tank is prone to scale deposition on the sides and the mixing propeller gets scale build up, too.  A Triangular Wave Deposit Control System to treat the water to be mixed will keep the tank sides and propeller clean of scale.

Wastewater treatment plant gains significant performance improvement and reduces operating costs by over $100,000 per year
Slurry pumps The pumps used to pump the slurry into the water stream are subject to scale buildup to the extent that two pumps are needed; one to pump while the other is being cleaned.  A Triangular Wave Deposit Control system placed on the suction side of the pumps will prevent scale deposition on the pumps.  The savings on labor for just a few weeks will pay for the deposit control system.
