The purpose of aerating wastewater is twofold:
1. To supply the required oxygen to the metabolizing microorganisms; and
2. To provide mixing so that the microorganisms come into contact with the dissolved and suspended organic matter.
Proper aeration is also a proven strategy for preventing hydrogen sulphide formation and controlling odour in wastewater. The Patented Double Bubble Technology™ utilized by the ARES Aerator is designed specifically to mix and aerate in one portable unit. The ARES utilizes fine bubble diffusers to efficiently supply oxygen while attaining a high level of aeration energy efficiency. A coarse bubble static tube creates the mixing. This allows the microorganisms to contact with the dissolved and suspended organic matter.
Our aeration systems for water treatment are designed to provide efficient mixing and oxygenation for municipal and industrial facilities alike.
The Ares Lagoon Aerator cut its teeth in Municipal Wastewater Treatment over a decade ago. With both mixing and aeration incorporated into one portable aerator, the Ares can be successfully utilised in:
• Wastewater aeration lagoons
• Treatment tanks
• Flow equalization basins
• Reclaimed water storage reservoirs
• And much more.
Our ARES Lagoon Aerator is one of the leading aeration systems for water treatment, combining fine and coarse bubble technology for optimal results.
Let us put our 30+ years of wastewater engineering experience to work for you!
Extensive independent testing has proven that the Ares Aerator has a best-in-industry Standard Aeration Efficiency (SAE). The MARS is 50-60% more energy-efficient than high-speed surface aerators and 40-50% more efficient than coarse bubble diffusers.
Energy efficiency is further enhanced by the patented Double-Bubble Technology which allows custom optimisation of each system’s fine bubble (oxygenation) and coarse bubble mixing demands.
The Ares Aeration System includes a broad range of product models and options. Our engineering team designs systems that are customised to meet your facilities unique requirements while also targeting the fastest possible project payback period with significant energy savings. This payback period often falls within 12-36 months.
1. Aeration, Mixing and Portability. – The Ares Lagoon Aeration System provides aeration and mixing in one portable unit. Utilising both fine bubble aeration and coarse bubble technology, the Ares is able to achieve efficient aeration and thorough mixing of the water column.
2. Easy Installation. – Ares Aerators are simple to install to any wastewater lagoon facility. Each self-weighted unit is connected to an on-shore air supply via flexible weighted tubing and lowered into the water.
3. Simple Maintenance. – Maintenance of the Ares Aeration System is equally as simple and can be completed from the surface without incurring system downtime. This hassle-free modular design allows for the MARS to treat any size wastewater facility.
1. Coarse Bubble Mixing: Large bubbles are released at the bottom of the static tube creating a draft effect that pulls water and liquefied organic matter up from the basin floor. . This results in complete system mixing by thoroughly churning and circulating the water column.
2. Fine Bubble Aeration: Fine bubble diffusers surround the static tube, maximising oxygen transfer efficiency (OTE) while minimising energy consumption. Enhanced by the mixing effect of the coarse bubble, this combination provides the ideal environment for biological treatment.
The ARES Lagoon Aerator incorporates fine bubble diffusers wastewater technology to provide efficient oxygen transfer for optimal aeration and enhanced biological treatment.
Our wastewater treatment systems feature these fine bubble diffusers to maximize oxygen distribution and further improve overall aeration efficiency.
3. Optimised Energy Distribution: The Ares’ modular design allows for treatment to be evenly distributed throughout the entire lagoon, mixing and aerating from the basin floor to the surface.
1. Ease of Maintenance: Each Ares is a portable aerator that is self-weighted and equipped with a stainless steel tether and locator float. When necessary, individual units can be easily lifted to the surface for servicing without the expense of dewatering or the inconvenience of system downtime.
Each unit uses fine bubble diffusers wastewater technology, minimizing fouling and maintenance requirements while enhancing oxygen distribution.
2. Centralised Air Supply: Air can be supplied to the entire Ares Wastewater Lagoon Aeration System by a single, centralised on-shore blower. If needed, additional blowers can be provided to meet sizing, layout or redundancy requirements. For further energy savings and control, Variable Frequency Drives (VFD) and Dissolved Oxygen (DO) meters can be incorporated.
3. Anti-Fouling Design: The MARS Aerator resists fouling, clogging and general ‘wear-and-tear’ in several ways:
A. Utilising self-checked fine & coarse bubble diffusers
B. Using self-cleaning EPDM fine bubble membranes
C. Elevating the diffusers above accumulated solids
D. Eliminating all submerged moving parts.
Fine bubble diffusers such as our Bubble Tubing® produce many tiny air bubbles (less than 1 mm in diameter). Tiny bubbles rise steadily from the floor of a wastewater treatment basin or the bottom of waterways and canals, ponds, lakes or lagoons. These bubbles provide substantial and efficient mass transfer of oxygen into the water. This oxygen, combined with the food source, sewage or sediment, allows naturally occurring bacteria to produce enzymes. Enzymes help break down waste or sediment made of accumulated organic matter.
The size of the bubble matters greatly for the application as we have noticed in our work. The fine bubbles (microbubbles) are critical for achieving precise results whether oxygenating a waste water treatment plant, using aeration to biologically remove excess nutrients, or using aeration for fluid mixing. Air bubble curtains applications that rely more on mixing and moving water also benefit from billions upon billions of microbubbles produced by Bubble Tubing®. Not only do bubbles transfer oxygen and decontaminate water by oxidation, but they also move and mix, clarify, and de-stratify water. Thus the same technology has many diverse applications.
Bubble Tubing® optimises oxygen transfer and lifts water which aids in total circulation throughout the water column. As it functions without moving parts or electricity in the water, it increases performance efficiency while significantly reducing electrical and maintenance costs in comparison to other aeration systems. This tubing, made of highly resistant yet flexible PVC, is non-kinking and holds no memory when deployed.
Compressed air enters the tubing creating an inner pressure. It is released through the perforations thanks to the precision holes found along both sides of the entire length of tubing. The ensuing micro-bubbles are efficient in preventing clogging and fouling (typically found in porous diffusers), of the entire length of tubing. They form a bubble curtain of uniform and evenly dispersed fine bubbles.
No matter the scale of operations the same basic principle applies: A compressor’s heat hose is attached to the airline delivery hose which itself is connected to the Bubble Tubing® equipped with a check valve. The compressor pushes the air through both the feeder hose and the diffuser tubing that releases the air uniformly into the water.
We offer all the necessary products from start to finish, to fully set-up a reliable and efficient aeration system for you. We can size the compressor for the application, suggest tubing layout, suggest cost effective design modifications, and offer to troubleshoot. Our experience designing aeration and deicing systems with Bubble Tubing® is substantial, and our expertise is sought for many aeration projects.
Bubble curtains also meet the requirement for containing silt and turbidity for in-situ work where sediment containment barriers are mandatory. When operating in a stream, river or lake, marine construction and dredging companies are required to install a physical curtain called a floating turbidity barrier.lick on picture to enlarge
These obstacles do not allow free passage for boats and work equipment. Whereas a bubble curtain does both: it allows movement of boats and equipment over the barrier while retaining sediment and other suspended matter. In this case, a bubble curtain installed from the stream, river or lake bed will mitigate the migration of silt and other suspended sediments through the water column.
Our Bubble Tubing® has proven to be very useful as a silt barrier and turbidity curtain during these applications. Also, in this article, research is currently underway to validate the effectiveness of bubble curtains in altering stream dynamics. Water currents in the outer curves of riverbeds are slower allowing for sediment deposition and accumulation. Over time, a sand bank can be created, making shipping impossible without dredging under certain circumstances. By installing a bubble curtain in this outer curve, this creates a sufficient current to prevent sediment buildup.
These are a few of the applications for Bubble Curtains. We look forward to working closely with engineers, scientists and water managers to find bubble curtain applications to protect wildlife and the environment so projects can move forward in an environmentally responsible manner.
