TDS Peak Shaver

Optimized TDS Discharge Management

Reduce the total dissolved solids (TDS) in your wastewater discharge and stay in compliance, while only treating as much as you need to. Saltworks can help you to take full advantage of your TDS or specific ion discharge allowance, while minimizing treatment required and residual waste generated.

Don’t Treat the Full Flow

To maintain TDS compliance, you may not need to treat the full flow, to the full extent. This allows ‘peak shaving’ opportunities, i.e. lowering the TDS by the optimal amount so that you remain in compliance, while still taking full advantage of your discharge limit.

 

Peak shaving requires sound process engineering and control, as well as high recovery systems to minimize TDS waste shaved from your peaks. If your project is reaching or exceeding your TDS discharge limit, Saltworks can help.

TDS Peak Shaving Example

Your process may be permitted to discharge 3,000 mg/L TDS, but you may see discharges approaching 4,500 mg/L. To resolve this, you don’t need to fully treat the entire flow. You only need to treat and manage the waste generated from the difference (i.e. 4,500 – 3,000 = 1,500 mg/L). We have options and solutions for you:

  • Identify the primary source of the TDS at its highest concentration, and target treatment at that point
  • Treat a portion of the flow, and re-blend to meet the final discharge requirement 
  • Minimize the brine generated with our high recovery membrane and thermal systems such as XtremeRO and SaltMaker AirBreather  
  • If your TDS load changes over a 24 hour basis (e.g. from over during the day, to under during the night, there may be a novel and low cost means to manage that brine waste.

Peak Shaving: Ask Us How

We can help you work through a TDS Peak Shaving analysis. Together we can strategize to lower your treatment costs, while also producing less residuals such as concentrated brine or solid salt. Contact us with your wastewater analysis, treatment goals, and flow rates.

 

If your TDS discharge fluctuates, be sure to let us know. We may be able to save you money and waste generated through sound process control.

How to Manage Brine Disposal & Treatment

The many options for managing brine, a term for saline wastewater from industrial processes, fall under two categories: brine treatment and brine disposal. Brine treatment involves desalinating the brine for reuse and producing a concentrated brine (lower liquid waste volume), or residual solids (zero liquid discharge).
