WATER REUSE CHALLENGES

• To preserve the natural environment• To manage water resources• To relieve the traditional resources• To propose alternative water resources

Countries that are concerned: the United States, Australia, China, Singapore, Spain, Middle-East Countries, North Africa…

REGULATIONS:•No real consensus in the world•Many countries with the greatest water stress have developed standards or regulations to develop Reuse.

OPERATING PRINCIPLE

Oxyblue™

Ozone is the most powerful chemical oxidant used in water treatment.

In Oxyblue™, ozone attacks the refractory COD.

OZONATION

REUSE

77

OPERATING PRINCIPLE

Oxyblue™

Compact biological filtration system, BioforTM, integrating fixed biological cultures (expanded clay beads on which micro-organisms develop).

In Oxyblue™, the bioreactor eliminates biodegradable COD produced during the first treatment step.

BIOFILTRATION

Oxyblue™

Oxyblue™ ADVANTAGES

• ENVIRONMENT:– Up to 60% of COD eliminated as well as trace pollutants,– Allows effluent discharge possible into sensitive zones.

• SAVINGS:– Competitive technology as tertiary process compared with

the usual other usual competitors technologies : ozonation and absorption on activated carbon,

– Significant reduction of wash reactive consumption and increase ultrafiltration equipment longevity thanks to membrane reuse treatment.

• FLEXIBILITY IN USE:– Small footprint and modular design supports rapid,

adaptation to the variations of loads and flow rates.

Case study : PETROCHINA, CHENGDU, CHINA

CONTEXT :

• Construction of a water treatment plant on the Petrochina industrial site in Chengdu

• Objective : The restricted water resources and the regulatory discharge limits, particularly on the COD, led the company to reuse close to one third of its wastewater from its plant which will treat 60.000 m3/d

• Commissioning on going

DESIGN :

• Oxyblue™ is intended to improved the reliability of the functioning of membrane ultrafiltration and reverse osmosis stages and to treat the osmosis concentrate produced for discharge into the natural environment

• Respective treatment capacity : 1 600 m3/h and 430 m3/h
