Disposal Well Protection
Saltworks can reduce 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.
Disposal wells are an important means to safely dispose of many of the most hazardous fluids deep underground. Disposal wells may face challenges such as:
- Plugging of active wells, caused by the mixing of different wastewaters with incompatible dissolved ions
- Regulatory limits to injection pressures and volumes due to seismicity or leaking risks
Saltworks can help with both of these challenges.
Protect Against Plugging
When two different wastewaters are allowed to co-mingle, a water-insoluble solid can be precipitated. This risks plugging the well. One example is the mixing of sulfate- and barium-rich waters, which react to form barium sulfate.
A real-time sensor can protect a disposal well by screening the wastewaters for high content of incompatible ions. Controls using our ScaleSense sensor can divert an incompatible flow into a separate stream, which we can inexpensively treat before disposal, for example with a product like BrineRefine.
Volume reduction options can help to achieve the best use of disposal well pressure and volume capacity. Our membrane products—such as XtremeRO—can produce a more concentrated, lower volume fluid. Our SaltMaker evaporators can reduce volume further, with options to suit your energy, chemistry, and capacity needs.
Saltworks’ volume reduction experts can help you to understand your treatment and disposal options, including discharge regulations and economics.
