leachate scale in pipe


Mineral scale and inorganic hard scales can lead to any number of problems, including lost production, increased maintenance and utility costs, poor product quality and unscheduled downtime. FlowScience Scale Control Systems control the formation of virtually any type of scale, including common calcium scale and less common barium, magnesium, manganese, silicate and sulfate scales. We custom design our systems to be a permanent solution to chemicals, jetting and pipe replacement without affecting your operations.  GUARANTEED.

Scale Precipitation is governed by several key factors:

1) pH: Most calcite precipitation occurs under alkaline                  conditions from pH 8.7 to  9.5

2) Temperature

3) Chemical strength of  leachate/saturated and unsaturated        condition

4) A catalyst (e.g. urease or carbonic anhydrase), and

5) The flow regime

6) Bacteria

certain groups of bacteria capable of precipitating calcium carbonate do exist and can survive the extreme conditions of high concentrations of inorganic salts and highly alkaline pH regimes that are characteristic of leachate

Catalyst:  “highly-loaded” leachate with higher concentrations of organic acids and cations

Thus, the composition of the leachate (e.g. organic acids, inorganic cations and suspended solids concentrations) entering the LCS has an important role to play with respect to the rate of clogging

Accelerators: Ash, Aluminum Dross, High Temps, High pH

Treatment Pads attach to the exterior of all types of pipes.  The control hub produces a pulsed field that changes the charge of dissolved and suspended solids changing nucleation physics.  Dissolved solids become the path of least resistance and form microscopic seed crystals that pass through solution.  As a bi-product of the charge; billions of nano CO2 bubbles dissolve existing scale from surfaces.

The FlowScience system uses advanced signal generating technology applied to water via proprietary web induction treatment pads that are attached to piping, pumps or custom designed reaction chambers. This technology produces an electrically generated surface active catalytic effect in water that neutralizes the natural charge of suspended solids.

The technology, in effect, creates billions of available nucleation sites out of the suspended solids in the water that were previously unavailable due to their natural charge. When nucleation occurs, the dissolved calcium carbonate follows a path of least resistance by precipitating as microscopic seed crystals onto the suspended solids that are in solution with it and travelling at the same rate, rather than onto static piping or equipment surfaces.

Dissolves & Eliminates Existing Scale

1.  The precipitation reaction previously outlined above transforms the previously supersaturate solution into a lesser or undersaturated solution that has greater ability to dissolve existing calcium carbonate scale and carry it in solution.

2.  Descaling can also be attributed to the liberation of dissolved CO2 from leachate solution as CO2 nanobubbles. These nanobubbles have a localized low pH in the range of 4 to 4.5. Physical contact of the acidic bubbles with existing scale promotes a carbonic acid affect that softens existing deposits. These bubbles have little affect on the bulk pH solution
