WebNov 17, 2014 · Scale Factors: Reducing Corrosion in Pipelines with Electronic Water Treatment. Increasing pressure loss in the pipeline is often caused by scale corrosion or product fouling of the internal surfaces. As such, Electronic Water Treatment is a non-invasive, environmental and cost-saving solution to treat these pipelines so that damaging … WebSoluble Na Scale in FF Evaporators Slide 9 and Concentrators •Falling film evaporators are notsusceptible to burkeite scale •Concentrators typically operate where dicarbonate fouling can occur •All concentrators are crystallizers –Want crystallization on suspended solids, not heater surface –Dicarbonate crystallizes only on dicarbonate
WebJun 1, 2024 · The increase and the movement of differential signal as function of reaction time are associated with the deposition of the CaCO 3 scale layer and an increase in the thickness of the fouling layer. WebFor determining the biofilm formation by the fouling setup, two small stainless-steel tubes, from the fouling loop (Figure 2, component 7), were removed each day of the 5-day biofilm medium circulation to monitor the development of robust biofilm. Each stainless tube was aseptically placed into a 50-mL screw-cap vial containing 25 mL of 0.1% ...
