How can we control biofilm growth in drinking water pipeline without increasing disinfectant dosing as WQ standards and not to end up with disinfectant byproducts due to excess disinfectant?
1160 ViewsPosted by Muthukrishna vellaisamy Kumarasamy on 06 Jul 2015 at 03:23Disinfectants obviously controls biofilm growth. But increasing dosing pose health problems as well. In addition, unpleasant taste and odour are results of increased dosing. Are there any other methods to control biofilm growth. Some studies say biofilm growth improves the efficiency o ...
Are there any practical tests done to precipitate fog artificially with fog-seeding as a potential water source in arid and semi-arid areas?
520 ViewsPosted by mussie fessehaye on 13 Jul 2015 at 06:04Fog-water collection with Large Fog Collectors is a proven method of water harvesting system in arid and semi-arid coastal areas but is there any practical test being made to precipitate fog artificially with fog-seeding at a larger scale as a potential source of water?

123 ViewsPosted by Andrew Kazantsev on 13 Jul 2015 at 08:46Yes, the great work was made by FogQuest group and MIT. However there is more global solution - AirHES (or Cloud Power) as a new huge source of renewable energy and fresh water worldwide. Look at this PDF for references: http://barixa.net/Mesh_airhes_en.pdf

82 ViewsPosted by Lincy P. on 13 Jul 2015 at 06:27Primary way of control biofilm is disinfection using chlorine and monochloromines. But these chemicals induce toxicity if concentration increases. It can be avoided by practicing some activities like 1. limiting residence time in collection systems 2. maintaining disinfectant residuals, ...

Magnetic polarization treatments reduces biofilm in pipes
134 ViewsPosted by Florent Perrin on 07 Jul 2015 at 08:42Hello, We have experienced very good results with our magnetic polarization treatment in pipes, primarly in internal networks like hospitals, but more recently in drinking water pipeline. Our treatement is originally designed for reducing scaling via cristalization changes from calcite to ...
