  • Outfall Water Quality Compliance
  • Cost/Effective Metals Removal
  • Optimal Selenium Mitigation Programs
  • Discharge Stream-Bed Staining Alleviation
Treatment Program

Our comprehensive location survey and lab support conducted by experienced personnel allows us to provide you with the most cost/effective treatment solutions for your process. Chemstream will perform a no-cost system evaluation and provide recommendations to resolve your water treatment situations and provide recommendations that enable you to be in compliance at the lowest possible cost.

Water source/quality 

Underground or mine pool water is generally oxygen-depleted and contains high levels of dissolved carbon dioxide, which increases acidity, lowers pH, and increases chemical demand. This situation increases the concentration of dissolved metals in your water sources. We will analyze and propose the best treatment options for outfall compliance.

Aeration 

Water with elevated levels of carbon dioxide acidity will benefit by aeration prior to chemical treatment. Off gassing the carbon dioxide will reduce the acidity of the water, thus reducing the consumption of alkaline pH treatment chemicals.

Treatment 

Chemstream can supply liquid caustic soda at various concentrations as an alkaline treatment choice to effectively raise pH to achieve effluent compliance. Chemstream also has a full line of flocculants and coagulants that can aid in the removal of suspended metals and/or clays. These products will increase floc size thus decrease settling time allowing for a cleaner discharge.

Retention 

Maximizing the surface area of a pond to increase the retention time of the water and will allow for lower contaminates in the discharge. Chemstream can provide pond partitions/curtains built and sized custom for your pond. Using pond curtains will also decrease the dissipation energy of the water allowing the floc to grow larger and entrain more particulate upon sedimentation.

Monitoring 

Chemstream installs and maintains state-of-the-art monitoring systems that utilize pH sensors, PLC’s, and wireless router modems that allow the pH and other parameters to be viewed remotely on your computer. In addition, our system can increase or decrease the chemical feed rates as the flow rate of the water varies. This promotes consistent water treatment results and clarified water that is in compliance all at lower treatment economics.

We supply several patented chemicals and innovative feed equipment designs to address your specific needs.

CF-1

A proprietary PAC blend used to treat for suspended solids (clays, sediment, coal fines), as well as dissolved metals.

CF-36 

An anionic solution polymer that improves floc size and integrity thus promoting rapid settling of suspended metals (iron, manganese, aluminum). This product can also be used as a secondary coagulant/coagulant aid in conjunction with CF-1 to quickly settle suspended solids when retention time is low.

CF-36X

A cost-effective, unique hard water scale inhibitor that prevents outfall stream staining, while keeping discharge water quality in compliance. Please click on the learn more link to view images and more detailed information.

Selenium Guard Stage 1

A proprietary, patent pending blend, that is capable of remediating both selenate and selenite to non-detectable levels. The Chemstream/Enviromine Selenium Guard program requires less space and is a fraction of the cost compared to other selenium remediation technologies.

Specialty Treatment Programs
AMD Treatment

A dual oxidizer that raises pH and oxidizes metals to effectively reach outfall compliance. Contact the Chemstream/Enviromine office or representative near you for more detailed information.

AMD-4

This product is a more powerful dual oxidizer than AMD Treatment for unique situations which may require unique chemistry. AMD-4 quickly raises pH and remediates dissolved metals. Again, please contact the Chemstream/Enviromine office or representative near you for more detailed information.
