1. Introduction
In August 2009 it was agreed that BIONEST would supply an évaluation unit to ALDAR to assess the
performance of BIONEST technology and equipment in treating wastewaters.
The location of the trial was agreed as Al Bandar project offices at ALDAR's Al Raha Beach Project. Grey
and Black water from the project offices would be treated to Abu Dhabi irrigation use standards as the
first benchmark. Ability to treat to a higher standard such as drinking water standards would be
assessed.
The test period would be monitored by BIONEST professionals in liaison with ALDAR's HSSE
environmental specialists. Ail equipment and shipping costs would be borne by BIONEST with port and
custom charges borne by ALDAR. A Technical Overview of the BIONEST process is attached at Appendix
A.
2. Order and Commissioning
1. Trial order placed with BIONEST July 2009
2. Trial Unit despatched Montréal, Canada August 2009
3. Trial Unit arrivai Abu Dhabi, UAE 11 October 2009
4. Trial Unit transferred to Al Bandar 18 -19 October 2009
5. Trial unit hook-up and commissioning 20 October 2009.
6. BIONEST unit operational at Al Bandar 20 October 2009
7. The unit has been on trial and operating without fault for 9 months
BIONEST Unit Established
3. The Trial
The trial was established at Al Bandar Project Offices to sub-sample and treat mixed grey and black
waters generated by office based staff. Approximately 300 staff works at the Al Bandar project offices -
working in shifts.
The BIONEST containerised treatment unit was established on hard standing in the project office
compound. The unit drew grey and black waters from the adjacent underground storage tank serving
the project offices. Flows for the trial were a sub-sample of total flow and this was controlled by a timed
pumpcontrol unit.
BIONEST Internai Framework
Approximately 7m3 of mixed greyand black waters per daywere sub-sampled and passed through theBIONEST treatment unit. As at End May 2010some 1560m3 (circa. 345,000 Imp. Galls) of mixed greyandblack water has been treated on site at Al Bandar. This has produced savings in both financial and
and improving conditions socially by reducing vehicle congestion on local highways.
Opération of the unit has continued for at least 8 months with little maintenance or other intervention
required. Periodic renewai of chlorinator tablets for final disinfection of outflow, as required in UAE, has
been the only real attendance need. An ozone generator, in lieu of chlorinator, has also been trialled as
chlorine disinfection of outflow is prohibited in other markets. Again this has been demonstrated to
workfaultlessly.
Installation and Trial of Ozone Generator
Throughout the trial period the electrical and mechanical components of the unit hâve operated to low
powerconsumption requirements.
Treated outflow has been shown to comply with applicable irrigation water standards and also local
drinking water standards. For the trial the outflow has been utilised for dust suppression and for vehicle
cleaning.

Plant Installed and Running
Prior to the trial, a daily collection of ail grey and black waters generated was necessary, because the
storage tanks at the Al Bandar project compound possessed limited storage. Approximately 225 tanker
collection and disposai journeys hâve been avoided - and typically thèse may hâve cost 220 Dhs per
collection. This equates to some 50,000 Dhs collection and disposai savings over the period of the trial.
4. Water Quality Testing
Throughout the trial period BIONEST professionals hâve regularly attended the unit to undertake site
based quality testing of the treated water.
Thèse site based quality checks hâve been verified and validated by sample testing at quality approved
and accredited laboratories. Irrigation water compliance has been confirmed as has drinking water
standard compliance. Copies of the test certificates are included at the end of this report as Appendix B.
High Quality Reclaimed Water Delivered
5. Treatment Costs and Disposai Savings
Over the period, the trial has diverted nearly 1560m3 (345,000 gallons) of effluent from tanker transport
and treatment off-site. Transport and treatment cost savings are assessed as follows.
• TankerJourneysSaved
• Tanker/Treatment Costs Saved
• Trial Costs to ALDAR
225
Circa 50,000 Dhs
Circa. 30,000 Dhs
So, it is clearly demonstrated that the trial was at no cost to ALDAR. In fact a saving has been delivered
to ALDAR in undertaking the trial.
For more permanent installations, savings will support investments in quick time, and preferential crédit
terms can be offered by BIONEST - backed by the Canadian Government. In essence opération of the
units will generally cover investment costs fully in a staged payment arrangement with payback in less
than 15 months.
Thereafter, larger annual savings will accrue to ALDAR as the capital investment will hâve been paid off.
ALDAR, through Export Development Canada (EDC), already has an approved crédit line for purchasing
Canadian products and services. BIONEST will secure attractive payment terms structured in the form
20% initial payment with the residual 80% financed upfront by EDC. This gives ALDAR the flexibility to
pay the outstanding amount through 18 equal monthly instalments free of interest. Thèse arrangements
are confirmed by the Abu Dhabi Division of EDC.
Considering that the typical payback period will be of the order 11 -14 months, this crédit arrangement
is extremely attractive, as ALDAR will be able to balance savings against outlay.
In addition BIONEST is very happy to support ALDAR and Abu Dhabi in moving forward under Plan 2030.
BIONEST looks forward to meeting with ALDAR senior management teams at the earliest opportunity to
discuss mutual opportunities in respect of spécifie operational, development and marketing initiatives.
BIONEST is particularly focused on the benefits that joint venture arrangements can bring to support
wider roll-out of Systems within Abu Dhabi.
Test Reports confirming compliance with Abu Dhabi water quality parameters are shown at Appendix B.
6. Business Case
The Business Case in support of use of the BIONEST technology is summarised as follows:
Environmental
• Alignment with Corporate Policy Statement on Environment and CSRalong with ALDAR Vision
• Réduction in Carbon Emissions
• Préserves Water Resources
• Treatment at Source
• Sustainable Approach based on Sound Science
• LEED / ESTIDAMA (potential for innovation and water conservation crédits)
• Turks and Caicos - Caribbean BIONEST has garnered around 80% of the market - mainly resortsin sensitive environments as BIONEST's ability to deliver low BOD effluent is a strong selling
point - particularly where protection of corals is a prime focus.
• BIONEST effluent meets or betters the world's highest effluent treatment standards - Europe /US - NASF certifications. See website for further information:
• Other innovations - which can include recirculation of treated waters for toilet flushing. Use ofdrinking standard waters in ALDAR ready mix concrète production.

De-centralised treatment at source - avoiding pipelines and pumping to central treatment sites
Re-use in Ready Mix Concrète production - préserves water resources
Distribution and Rental initiatives-commercial returns
Landscaping
Re-use of water for toilet flushing (only)
8. Conclusions
The BIONEST technology has been proven to be efficient, robust and reliable.The unit has low power
and consumables (chlorlne tablets) consumption.
Test data has confirmed achievement of local standards for both irrigation and drinking water purposes.
Technically there is no reason why this technology cannot be adopted by ALDAR -subject to BIONESTand its supporting partners obtaining the requisite approvals for spécifie installations. This will include
satisfying regulators on user competencies in opération, monitoring and reporting. ALDAR has already
proven its credentials in this regard and is a licence holder with Abu Dhabi Régulations and Supervision
Board (RSB).
Options for commercial collaboration are also available. BIONEST is keen to discuss distribution
partnering arrangements with ALDARto roll-out this technology wider in Abu Dhabi.
9. Recommendation
On a project by project basis the incorporation of BIONEST technology can now be readily considered by
ALDAR's Project Teams. Indeed in certain circumstances, such as remote locations, this containerised
and stand-alone treatment approach may be the most applicable option. This may apply to remote
areas of ALDAR's Operative Villages, remote residential villa complexes, resorts - not connected to main
sewerage.
Close liaison with BIONEST technical professionals is recommended to ensure Systems are fully tailored
to project requirements - in terms of population, wastewater volumes, adéquate pre-settlement tank
volumes, optimised gravity designs, underground or surface mounting of treatment equipment, odour
control, permits, commissioning, spare part inventory, monitoring, maintenance, O&M Manuals and the
like.
Early use of BIONEST technology can deliver savings throughout the construction phase of a project. The
units can then be relocated to the next upcoming project.

APPENDIXa - Overview of BIONEST System
BIONESTTechnology
The BIONEST System is a submerged fixed film bioreactor which uses a proprietary non-biodegradable
média. The treatment process takes place in two tanks installed in séries. The primary treatment
comprises a conventional two compartment septic tank with effluent filter. The second tank is also two
compartments and is the "bioreactor" which contains a spécifie quantity of proprietary BIONEST média
within each compartment.
Continuous aération of the first compartment of the "bioreactor" is achieved through a linear air pump
and fine bubble air diffusers. A recirculation pump is installed in the last compartment of the bioreactor
and part of the treated effluent is returned to the septic tank.

Summarv of Analvtical Test Reports on Water Quality
Across the board the foregoing results display System performance far exceeding régulatoryrequirements. The analvtical test reports shows compliance to both irrigation water standards withinAbu Dhabi and also for drinking water standards when compared to applicable Gulf and World HealthOrganisation (WHO) guidelines.
For irrigation waters the pHvalue at 25°C is within the range accepted by Abu Dhabi authorities. TotalSuspended Solids are less than half of the allowable limit as are Total Dissolved Solids. The ChemicalOxygen Demand is less than 25% of the maximum allowance and Biochemical Oxygen Demand wasreported at40% of the maximum limit. Metals were consistently reported at less than laboratorydétection limits. Fecal coliforms were not detected in a number of the laboratory analysis and returnedlower than allowable limits in the remaining analyses.
For drinking water, appearance was reported as Clear and odour Normal when reported against Gulfstandards for unbottled drinking water. For pH and Conductivityat 25°Cthèse were reported withinacceptable limits. Total dissolved solids were detected at less than half of allowable concentration. Theparameters chloride, sulphate, calcium, magnésium and total hardness were ail reported withinacceptable levels. For a suite of metals thèse fell within the accepted limits.
Potable water submitted for bacteriological analysis was described as - "ofsatisfactory quality andwithin the specifled limits"-when compared against WHO guidelines.
