How do I know which cleaning method to use to clean my membrane system?In order to get the best cleaning results, it is important to choose the right cleaning agent and cleaning procedure, as incorrect cleaning can actually deteriorate the system performance.Why is the pH of the RO produced water lo Read More

What is the relationship between influent TDS and conductivity?When a feed water conductivity value is obtained, it must be converted to a TDS value so that it can be entered in the software design. For most water sources, the conductivity/TDS ratio is between 1.2 and 1.7. For ROSA design, a ratio o Read More

Treat high turbidity water with a membrane designed for greater solid tolerancesVeolia's（Suez） immersed ZeeWeed 500 membrane is specifically designed for difficult-to-treat water sources. Drinking water, wastewater, water reuse, and industrial applications can all benefit from Veolia's strongest Zee Read More

What kind of pretreatment is generally required for RO systems?The usual pre-treatment system consists of the following, coarse filtration (~80 microns) to remove large particles, addition of oxidants such as sodium hypochlorite, followed by precision filtration through a multi-media filter or clari Read More

1. Forward Osmosis (FO) technologyThe principle of forward osmosis (FO)The solvent is separated from the solution by a semi-permeable membrane that can only pass through the solvent but not the solute molecules. The solvent molecules will spontaneously pass through the membrane from the solvent side Read More

What is a split membrane bioreactor?Separate membrane bioreactors use the membrane module as a separate unit from the bioreactor, the mixture is pressurised by the system into the membrane module, the permeate of the membrane module is the effluent of the system and the concentrate of the membrane m Read More

PTFE (Polytetrafluoroethylene, trade name "Teflon", commonly known as "King of Plastics") was discovered in 1932 by Dr. Roy Plunkett, who came to the United States after graduating from DuPont to work on organic fluorine. In the summer of 1938, he discovered the white powder polymer polytetrafluoroe Read More
