Water Solutions & Specialty Chemicals (WSSC)

Chemtrade’s WSSC business segment operates an extensive North American plant network, producing both traditional industrial chemicals and customized solutions for our customers. The Water Solutions segment consists primarily of inorganic salts, used as coagulants by municipal and industrial customers to treat water and wastewater. Additionally, the Water Solutions team produces a group of products used by poultry growers, as litter amendments, to control ammonia volatilization and improve bird health and productivity.

Along with coagulants and poultry litter amendments, WSSC produces Specialty Chemicals used in a wide range of industries including the paint (ink, pigment, etc.), oil & gas, pharmaceutical, nutraceutical, food & beverage, and tantalum refining industries.

CAL~FLO® (Calcium Hydroxide Slurry)

CAL~FLO® (Calcium Hydroxide)

Chemtrade’s CAL~FLO® slurry is a high-quality liquid calcium hydroxide used in various municipal and industrial water and wastewater treatment applications. We can supply CAL~FLO® slurry from multiple locations in North America. With a fleet of test trailers, we can offer full-scale, on-site product demonstrations with full technical support. Following a successful trial period, we are also able to provide technical assistance in the design and installation of equipment required to store and feed CAL~FLO® reliably into your process.

CAL~FLO® slurry has been used successfully in a broad range of applications in municipal water and wastewater markets. It is also used in a range of industrial processes that require reliable, accurate dosing along with safe and low-maintenance feed equipment.

Municipal Drinking Water

CAL~FLO® slurry meets NSF/ANSI/CAN Standard 60 requirements for chemical additives to drinking water. Through strict quality control in its manufacture, each CAL~FLO® slurry shipment is checked for suspension consistency. The most common application points for CAL~FLO® slurry in the drinking water industry are:

  • Clearwell/Filtered Water Line: CAL~FLO® slurry typically replaces liquid caustic soda (sodium hydroxide) for pH adjustment. It also provides alkalinity and calcium hardness to address potential corrosion concerns in the distribution system. CAL~FLO® slurry is a safe product for operations. Customers find their spend more consistent than when using caustic soda.
  • Raw Water Feed Line/Rapid Mix: CAL~FLO® slurry typically replaces dry lime for alkalinity adjustment, which can be required for more effective coagulation and minimization of metals residuals. The change to CAL~FLO® slurry eliminates the high maintenance and unreliable feed problems associated with dry lime and leads to more consistent treatment.

Municipal and Industrial Wastewater

CAL~FLO® slurry is a consistent source of alkalinity which can be required to neutralize acids, help biological processes, or increase pH for effective operations. CAL~FLO® slurry has also been used to improve solids stabilization and processing as well as address H2S concerns.
