AQANA® CONCEPTS

An anaerobic process is a beautiful and simple natural occurrence. With the absence of oxygen waste is converted to biogas and only a small amount of sludge. But as in most cases, a human synthesis of a natural process ends up very complicated. Aqana® takes advantage of the bacterial property to attach to surfaces. The anaerobic bacteria are grown on a floating carrier. With this Aqana® makes the difference. By using a floating carrier bed the reactor design is that simple that it fits in any tank. Three concepts are the product of the research and collaboration with launching customers.

PARTNERSHIP

From our company in the Netherlands we operate worldwide in wastewater treatment. In achieving our goals we are continuously expanding our partnerships to share our technology and realize local projects.

In our specially developed partnership program, we closely collaborate with license partners and share the possibilities of the Aqana® system.

We are focused on companies active in wastewater treatment, who are missing the anaerobic technology in their portfolio.

REFERENCES

Together we would like to determine how Aqana® can share a wastewater solution. Without a doubt one of our concepts will fit your situation.

To realize your solution, you can count on the Aqana® team that represents top level experience in industrial anaerobic wastewater treatment. The Aqana team stands for years of experience.

From the Netherlands or through our local partners we can build a complete wastewater treatment plant. We also have the possibility to send a complete installation packed in shipping containers.

Successful pilot test with DACS in a brewery

Germany - Summer 2012

AQANA has run a successful test with its 100 l pilot plant in one of the largest breweries in Germany. It has shown that DACS can reach the same quality of effluent like other anaerobic technologies under high loading rates. Many breweries are searching for an upgrade of their wastewater treatment because most of them operate an aerobic pretreatment with significant energy input for aeration and sludge production. These plants can be converted into anaerobic systems without building new tanks thanks to the flexible configuration of DACS. These promising results creates a lot of interest in the European beer and beverage industry from Norway to Italy.

Second pilot test in potato factory

Germany - November 2012

AQANA starts up a second pilot test in a potato factory to confirm and specify design parameters for a DANA plant. Due to the fact that AQANA has for over a year of experience with potato wastewater, it will need only two months to secure promising performance expectations.

Finishing pilot test in potato factory

Germany - February 2013

AQANA has finished a very successful pilot test with its large scale pilot plant in a potato factory. Beside excellent conversion of dissolved COD it has shown that also large amounts of solids can be converted into biogas without disturbing the process of conversion of dissolved COD.

DIRECT BIOMETHANE from DACS

Netherlands - May 2013

Based on field measurements in the large scale pilots in Germany and Italy, it has been proven that DACS is able to produce biogas with very high methane concentration. This is due to its Downflow concept. During a pilot test in our research facility, it has been proven that DACS can covert organic solids directly into biomethane(results confirmed by certified lab). This feature will save enormous investment and operational costs of an upgrading plant for grid injection projects and will improve the economy of "green gas" projects.

AQANA DACS and Aqwise MBBR in an Italian paper mill

Italy - June 2013

AQANA finalized a successful pilot trial with its industrial scale pilot in an Italian paper mill. It has been shown that the combination of DACS and MBBR can reach significant lower effluent values than the existing MBBR. This allows the client to improve the water circuit and its energy balance.

First order for a full scale DACS in pulp and paper

Italy - July 2013

Based on the successful pilot results AQANA gets the first order for a DACS in the pulp and paper industry. The plant will be realized inside the existing concrete MBBR Tank. Erection of DACS will take place in spring of 2014.

Integrating DACS in an Italian paper mill

Italy - July 2013

AQANA's industrial pilot has been moved to a second Italian paper mill. Similar to the first mill, this client want's to improve performance and economy of his effluent treatment. Due to high Calcium contents of up to 600 mg/l, the pilot has been reconfigured.

Engineering order for DACS/MBBR in potato industry

Germany - July 2013

A BOOT contractor has granted AQANA the order for an unique large scale DACS/MBBR treatment plant for a potato factory. This DACS/MBBR has to be "mobile" to be able to move to another location within a few years.

Treating distillery effluent.

Netherlands - August 2013

AQANA has been testing distillery effluent at its research facility in Sneek. Due to the composition of the wastewater, all other established anaerobic systems need complex and expensive pretreatment. DACS has proven its potential to convert organic solids parallel to dissolved materials, in a stable anaerobic process. AQANA will provides a simpler concept essential for successful and economic solutions for small scale distilleries.

Results from AQANA INDOOR Pilot plant

Netherlands - August 2013

During the first six months of 2013 AQANA's pilot plant has been fully booked for testing. Waste water has been brought to the our research facility for testing under extensive lab and personal control. Some surprising differences between DACS and established systems have been confirmed as added value to this new solution for anaerobic treatment. Proven was that the DACS can withstand: high solids, high salt concentrations and strong fluctuations. Also carriers have been proven scaling free during these test.
