QATAR - WASTE WATER AND DRINKING WATER TREATMENTS

THE IOW assured a mission of training session for the new employees of the company DEGREMONT in the purpose which they know and understand the processes of treatment of water used by DEGREMONT

CONTENT

DRINKING WATER TREATMENT

• - Resources and impurities (SS, turbidity, colloids, organic matter, bacteria, hardness, alkalinity….)
• - Procédés de traitement eau souterraine et eaux de surface
• - Principle of processes
• . Pré-traitements

. Clarification (coagulation, flocculation, sedimentation, sand filtration, flotation) : Pulsatube, Pulsazur Densadeg, Aquazur, Mediazur, Flotazur, AquaDAF, SeaDAF, Seaclean…)

• . Oxidation and disinfection (ozone, chlorine, chlorine dioxide, UV)
• . Activated carbon adsorption (Carbazur)
• . Membrane filtration : ultrafiltration Ultrazur and Cristal process
• . Desalination : reverse osmosis
• . Mineralization treatment : remineralisation (degassing, lime, soda, limestone filter)

WASTE WATER TREATMENT

• Pollution parameters ( SS, BOD₅, COD …)
• - Types of treatments
• - Principle of biological waste water treatment : free cultures (activated sludge process), fixed cultures (Biofor) and mixed cultures (Meteor)
• - Aims and principles of preliminary treatments : Arénis process, greases treatments (Biomaster and Carbofil)

- Primary settling: Sedipac D and 3D and Densadeg

- Activated sludge process and aeration systems: fine bubbles (discs and tubes), mechanical aerators (Actirotor) and submerged aerators (ABS and INVENT).

• - Biofilters cases : Biofor example
• - Tertiary treatment : Densadeg, Aquazur and Filtrazur
• - Reuse of waste water : disinfection, UV treatments
