SIDEM products
Barrel
The Barrel™ is a multi reverse osmosis (RO) element vessel which allows the RO process implementation to be strictly identical to that of current RO pressure vessels, ensuring the fresh water produced meets all desalinated water quality standards.
Spidflow
The flotation is made possible with a white water production (air and water mix under 5-6 bars) capable to generate fine air bubbles which are released in the system to occur the low density particules flotation. The Spidflow® hydraulic design has been particularly optimized with the help of CFD (Computerized Fluids Dynamics) calculation simulations. Some hydraulic management devices, associated downstream to a coagulation/flocculation stage, allow Spidflow™ to reach high clarification rates in the range of 30 to 50 m/h.
Advanced Technologies
DAF Filter
Combined High Rate Floatation and Media Filtration. The DAF Filter - patented as Spidflow Filter ® - is the unique re-engineered combination of Veolia`s two best-seller processes: SPIDFLOW® and FILTRAFLO TGV®. Long term performance of our DAF Filter has been assessed during extensive operation in challenging raw water conditions in different locations of the Gulf region.
M&C Filter
A compact pre-treatment solution for SWRO plants. M&C Filter consists of an innovative combination of dual media pressure filter (DMPF) and cartridge filters (CF). This feature reduces the footprint of the pre-treatment. This unique two-in-one pre-treatment solution allows to remove high turbidity and suspended solid particles from the feedwater. RO membranes are therefore protected and the risk of biofouling is highly reduced.
