Real-time ion sensor/analyzer for Ca2+, Ba2+, SO42- and SiO2

An automated, real-time sensor/analyzer for saline waters that measures calcium (Ca2+), barium (Ba2+), sulfate (SO42-) ions and silica (SiO2), ScaleSense was specifically developed to work with the toughest waters, after conventional real-time sensors failed to meet our needs.


Real-time sensors provide direct measurement of ion concentrations on a continuous basis. However, most struggle with the presence of total dissolved solids (TDS) >50,000 mg/L. ScaleSense overcomes this limit and is not impacted by TDS. 


Measuring scaling ions real-time enables process optimization. Use less water, make more water, generate less brine. See our spec sheet for more information.

Introducing Saltworks’ ScaleSense

Real-time scaling ion measurement and control can help you optimize your process: save money & reduce your water footprint, see the examples below.


ScaleSense is robust and configurable for Ca2+, Ba2+ or SO42- ions, or SiO2. It functions accurately and precisely, even at extremely high-TDS.


We can help you to integrate ScaleSense in your process: process assessment, drawing updates, PLC programming, training, and support.

injection disposal wells for wastewater

Disposal Wells

Saltworks reduces fluid volume by treating it with a range of solutions and products, depending on your needs. Upon mixing, some waters pose a risk of precipitating and plugging active disposal wells. We can protect disposal wells from plugging with our real-time sensors, by detecting incompatible wastewaters and preventing co-mingling.

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).

Cooling Tower Blowdown

Cooling Tower Blowdown

Saltworks can solve your cooling tower blowdown challenges. We can add novel sensors and controls to your cooling tower to minimize water consumption and blowdown production. We can treat blowdown for re-use at your cost-optimized freshwater recovery or achieve zero liquid discharge.
