Figure 8.18 Consistent dosage control of antisealant based on the 3D TRASAR system. Note the relatively narrow range of antisealant dosages resulting in few underfed or overfed episodes. Figure 8.18 Consistent dosage control of antisealant based on the 3D TRASAR system. Note the relatively narrow range of antisealant dosages resulting in few underfed or overfed episodes.
For practical purposes, it generally makes sense to use sodium softeners for RO feed flow rates of less than about 20 gpm rather than conventional, flow-proportional control difficulties in feeding based on flow control are exacerbated at low flow rates because of limited turn down on proportioning chemical feed pumps at low flow rates. However, when Nalco Company s 3D TRASAR technology is used, antisealant can be fed to RO systems operating feed flow rates as little as 3 gpm.2... [Pg.309]
