This document discusses OxyblueTM, an advanced wastewater treatment system combining ozonation and biofiltration to allow for water reuse. It operates by using ozone to break down refractory COD, followed by biofiltration to eliminate biodegradable COD. Case studies show it can remove over 60% of COD to sufficiently treat wastewater for reuse applications like at a Petrochina plant in Chengdu, China, where it treats 1,600 m3/h of their wastewater for reuse.

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.

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.

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
