Phosphonate removal from membrane concentrate by electro-coagulation

In this study, the efficiency of electrocoagulation (EC) with iron electrodes was applied to remove two phosphonates, 1-hydroxyethylidene-1, 1-diphosphonic acid (HEDP) and nitrilotris(methylene) triphosphonic acid (NTMP) from concentrates. This work provides a detailed description of the experimental procedure and results on phosphonate...

Insignificant impact of chemotactic responses of Pseudomonas aeruginosa on the bacterial attachment to organic pre-conditioned RO membranes

We investigated the impact of conditioning compositions on the way bacteria move and adhere to reverse osmosis (RO) membranes that have been pre-conditioned by organic compounds. We used humic acid (HA), bovine serum albumin (BSA), and sodium alginate (SA) to simulate conditioning layers on the RO membranes. First, we investigated the...

The Effects of Fluctuating Operation on Reverse Osmosis Membranes

Directly coupling renewable energy to reverse osmosis may be the most cost effective solution to supply potable water to remote and isolated areas that lack infrastructure and safe drinking water. These systems do not use batteries but rather operate only when sufficient energy is available and store any excess energy as water. Since reverse...
