REQUIREMENT

The Ajman Sewage Private Company Limited (ASPCL) contacted

Azzuro to solve performance problems with an existing biological

odor control system that had previously been installed to treat

extremely high loadings of H2S. Due to the inability of the existing

system to process these high concentrations, significant deposits of

elemental sulphur developed on the synthetic media. This caused

constant clogging of the media, which had an adverse effect on

performance.

The operator had been forced to routinely open up each of the 8

reactors, remove the media packs and tediously clean each media

pack with a high pressure wash and vibrators. This process was

obviously not efficient and it was wasting thousands of man hours

per year on unnecessary maintenance. ASPCL needed a more

capable process and higher quality media that would eliminate this

expensive problem and meet the strict emission requirements.

SOLUTION

The original layout of the system was for 8 biological reactors. Azzuro

was able to exchange the existing media with its Spacious Wire Pac

Media. Only 6 of the 8 reactors were needed to meet the stringent

performance requirements set forth by ASPCL. Not only did ASPCL

solve the emissions and maintenance problems by using the Azzuro

system, they now have 2 reactors left on site to use if needed for any

future expansion of treatment at the facility.

The Azzuro Spacious Wire Pac media has shown excellent results and

is removing 800 to 1.200 kg per day of Sulphur! Due to the unique

structure and design, the Azzuro media promises to never clog and will

not need the constant cleaning like the previous media. The operators

have been relieved of the maintenance associated with this system and

can now focus their efforts on other parts of the facility.

REQUIREMENT Sand Island WWTP (operated by The City and County of Honolulu, Hawaii) contracted with Azzuro in late 2007 to replace their existing carbon scrubbers with the more cost effective Azzuro Biological Odor Control System. Carbon replacement costs had became too much of a burden on the City’s budget at over $100,000/year. The Azzuro system promises to be much more cost effective over its lifespan as the biological system requires no media change out and almost zero maintenance. The Azzuro system needed to be robust and have the ability to handle large sudden spikes of H2S which had been exhausting the previous carbon at a rapid pace.

SOLUTION A total of thirteen (13) Azzuro TR36-6 bioreactors were installed to treat over 120,000 cfm of foul air. The foul air originated from Headworks (40,000 cfm/4 reactors), Primary Clarifiers (50,000 cfm/5 reactors) and Solids (30,000 cfm/4 reactors). The system has met performance every step of the way even during sudden spikes of H2S which have become commonplace at the plant. The owner is delighted with the ease of operation of the Azzuro system and obviously enjoying the cost savings that have been provided. The City is working with Azzuro again to find even more ways to optimize their plant and increases savings.

AZZURO

REQUIREMENT The Western Treatment Plant treats about 54% of Melbourne’s sewage. Raw sewage is delivered to the plant via the Western Trunk Sewer (gravity sewer). After a series of manholes, the sewer converted to an open channel. Prior to construction of the odour control facility, a single fan drew foul air from the sewer and vented to the atmosphere via a 30m high vent stack. This dispersion offered by the stack served Melbourne Water’s objective of no odour at the boundary. Melbourne Water’s plans to develop land in the north-east corner of the WTP for residential purposes meant the existing arrangement of the vent stack no longer met it’s objective. Therefore, an odour control facility was built to reduce odourus compounds and reduce the risk of odour complaints from the new residential development. Contractor: John Holland Pty. Ltd. Engineer: Sinclair Knight Merz & CH2M Hill

INTERVIEW WITH OPERATOR Q: After 8 years of operation, has there been any down time or

problems with the Azzuro system? R: Nothing significant. One time we had to take a tower offline

because a valve in the water cabinet was leaking. After replacement of the valve, the tower was brought back online and perfomrance was restored back to normal in the same day

Q: Do you still have the same performance? R: Yes. Even though we have seen our ingoing H2S

concentrations increase from 26 ppm to 100-150 ppm, the system is exceeding guaranteed performance.

Q: After 8 years of operation, do you have any pressure drop

issues? R: No, the pressure drop was guaranteed to be below 1000 Pa

and is consistently under 700 Pa

How does Azzuro’s High-Performance Torrenta Bioreactor work?

Contaminated air is introduced at the bottom of the reactor The air passes upward through one or more microbial beds and clean air is discharged at the top of the unit Humidification is accomplished by way of an advanced water spraying system designed to maximize growth of the biomass Foul air/Odorous air compounds are quickly degraded by the microorganisms, eliminating the emission problem
