Wastewater Treatment

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 wastewater lagoon aeration and mixing in one portable aerator. 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 System 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 System 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 produces wastewater mixing by highly agitating the water column, thoroughly churning and circulating the entire basin.

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.

3. Optimised Energy Distribution: The Ares’ modular design allows for treatment to be evenly distributed throughout the entire wastewater 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.

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.

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 wastewater 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.

• Bubble Tubing® is flexible, it holds no memory and will not kink, is easy to install and is safe for the environment (does not contain lead).
• Made exclusively in Canada to our exact specifications, impressive 5-year warranty.
• High oxygen transfer rate. A full evaluation of the oxygen transfer capabilities by independent firm available.
• Applications range from farm ponds to the largest industrial projects.
• Suitable for fresh and saltwater applications, from shallow to deep waters.
• Inner pressure prevents clogging; tubing is low maintenance, anti-fouling.
• No moving parts or electricity in the water.
• Highly resistant PVC (chemicals, salinity, temperature).
• Weighted and non-weighted formats available.
• Tubing can be purchased with all the necessary hardware, ready to be installed.

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.

When added to a lagoon, SELECT-Oxypack^® – Lagoon Oxygen Booster sinks down into the sludge layer. As the pack dissolves, peroxide liberates the sludge and punches holes in the muck layer. This increases the surface area and allows new pathways for the bacteria to get deeper into the sludge. The effect on the sludge layer is similar to core aerating your lawn. It also adds oxygen to the often anaerobic muck layer, to minimize odour production.

SELECT-Sediment^® and SELECT-Oxypack^® are also a good combination for wastewater operations with percolation ponds and rock filters.

Percolation ponds and rock filters tend to build up with sludge and dead organics. These clog the surface and prevent water from trickling through them. The use of both these products and help break up and digest organic matter so the water starts flowing again.
