The Performance of Different Anti-Sealants on Silica-Scaling in Reverse Osmosis Plants
The effectiveness of anti-sealants for calcium carbonate and calcium sulphate is often determined in laboratory tests like the NACE Standard Test Method 03-74. Due (o the different chemical scaling mechanisms of the calcium hardness and of silica these test methods are not found reliable to simulate silica scaling. To investigate the performance of different anti-sealants for silica at a reverse osmosis plant, a new membrane-based test method was developed and applied.Figure 1 and 2 show the typical curve obtained for the permeance versus time. Figure 1 gives an example of the results obtained without using an anti-sealant, while Figure 2 shows an example where an anti-sealant has been applied.
