Strategies to prevent silica fouling reducing costs in BWRO systems: Case study for 18,000m3/Day BWRO plant in Arica Chile
IMPACT OF OPERATIONAL STRATEGIES TO PREVENT SILICA FOULING IN REDUCING COSTS IN BWRO SYSTEMS: CASE STUDY FOR ARICA 18,000M3/DAY BWRO PLANT IN CHILE.In this paper cost savings of operational strategies adopted in Arica Desalination plant are calculated and presented. The importance of operational practices in reducing energy consumption is demonstra...
Cleaning biofouled membranes early improves plant operation. Comparison of autopsy and cleaning results on a small BWRO and large SWRO.
This paper discusses membrane element cleaning for a wide range of foulants and scales. The authors theorize that during the soaking process of a specific cleaning solution encourages natural osmosis of permeate water through the membrane to help remove biofilm and clay fouling layer. The paper also concludes for the cleaners tested that it was e...
The Role of Antiscalants in Improving System Performance
This presentation on antisaclants is from a preconference workshop in 2014 that discussed optimization in membrane plant performance. A preliminary discussion about scale formation along with it's importance in membrane systems is given. Diagnosing membrane system problems is given along with solutions to address each issue is discussed...
What?s New in RO Membrane Cleaning? Micro-Bubbles and High Ionic Strength Effervescent Cleaners Enhance RO Membrane Foulant Removal
The use of micro bubbles, effervescents, and high ionic strength cleaneres are explored for novel approaches for the removal of foulants on RO and NF membrane surfaces. The unique part of this is the use of venturi micro bubble generator in conjunction with specially formulated cleaning compound with the bubbles injected through a specially designe...
Practical examples of new ways to clean oil fouled membranes
This paper reviews current thinking on reverse osmosis (RO) membrane cleaning. It challenges preconceptions and describes novel approaches for the removal of foulants and scale deposits from membrane surfaces. Improved cleaning practices are required as membranes are increasingly used in extreme water associated with enhanced oil recovery and minin...
