Abstract: A blending system includes one or more tank platforms. The tank platforms are transportable via road, rail, or vessel. One or more bulk containers are located on the tank platforms. The bulk containers are capable of storing and handling concentrated fluids. A blending platform may be coupled to the tank platforms. The blending platform is transportable via road, rail, or vessel. A blending unit is located on the blending platform. The blending unit blends the concentrated fluids with one or more of the additive fluids and water to continuously produce fracking fluids as needed (e.g,. fluids are continuously produced on an on-demand basis). The fracking fluids may have a selected concentration of concentrated fluid, additive fluid, and/or water.
