This is the sound that the compressor makes when standing right beside it! It is not that noticeable especially when removed from it.

Turtle Mountain Conservation District

Derksen Hyde Dam – Aeration

Goal– to improve conditions of water and increase Dissolved Oxygen so that the body of water can be stocked with fish.

Installed – spring 2014

RM of Tache

Lorette – 3 Retention Ponds in newer development – 3- subsurface fine bubble aeration systems, bacteria and pond dye.

Goal- to improve the water quality, reduce algae, weeds and smell to please residence around the retention ponds. These ponds are thick with aquatic weeds and several feet of muck.

Installed– June and July of 2016

Red Algae has been an issue in the past

 

 

Treated water less than one year later – Lorette, MB

City of Winnipeg

Millennium Library Pond –  Shallow Water aeration, beneficial bacteria and pond dye

Goal – improve water quality and reduce care and maintenance. Reduction of algae present in the water.

Installed – July 2013

RM of East St. Paul

Silver Springs

Pilot project to prove the effectiveness of fine bubble aeration. System was installed in August 2016. Aeration installed. The West end of the pond was targeted only. Water was quite turbid with considerable aquatic growth.

Installed – August 2016

LG Sonic

The LG Sonic® technology controls algae, biofilm and some types of bacteria by sending ultrasonic sound waves of several specific frequencies into the water, which control the algae by resonance and sound pressure.

The LG Sonic® devices will emit ultrasonic sound waves, which are inaudible for humans. The ultrasound waves will travel through the water reservoir, bringing algal cells in vibration on its path. When brought into vibration these algal cells will rupture leading to the death of the algae.

Effected algae cells will sink to the bottom of the water reservoir, where they will be degraded by the bacteria present in the soil. After 3 to 4 weeks, the LG Sonic® devices control the growth of new algae with 70 to 90%.

It has been noted that when bacteria and algae use the same nutrient source and algae are controlled, more nutrients are available for the bacteria present. Therefore, bacteria will grow and multiply faster resulting in a greater reduction of nitrogen and phosphorus in the water. Thus, controlling the algae will have a positive influence on the nutrient issues within the water body.

Aeration – fine bubble subsurface

Many of our projects consist of the  LS60, 230V, fine bubble Aeration system is comprised of two 1/2HP rocking piston compressors and six ProAir4 diffuser plates. Each ProAir4 diffuser plates can handle between 1 and 6 CFM of air and circulates approximately 4000 gallons of water per minute. The systems are calibrated to deliver 1.93 CFM air per plate with a total of 11.6 CFM for the entire system.  The LS60 compressors are very energy efficient. Using a cost of $.07/kilowatt per hour, the estimated electrical consumption cost is only $51.00/month to operate the system 24/7.  In addition to a white finned filter on each compressor, the compressor cabinet has an air filter which supports longevity of the system.

In addition to cost savings to operate these compressors and the systems ease of maintenance, another very exciting component of the system is a built-in restart which provides peace of mind that even after a power outage the aeration will be up and running again. During times of power failure, the system will sit idle for 7 minutes allowing air pressure to escape before starting automatically.

The ProAir4 diffuser plates outperform other micro-bubble plates on the market and are really what sets it apart from a more traditional course-bubble aeration system. Course-bubble systems are designed to create open water during the winter months in order to promote dissolved oxygen levels. The ProAir4 diffuser plates do the same; however, they improve the quality of the water by stimulating breakdown of organic matter found on a lake’s bottom. The self-weighted, patented ProAir4 diffuser design has four air tubes with tiny holes 360 degrees around each tube to create micro-bubbles. The membrane on each tube is PTFE coated making it much less likely to clog. This coating also helps the membrane to maintain its integrity of the tiny bubbles as compared to a rubber membrane that tends to stretch and produce larger bubbles.  The micro-bubbles from these tubes keep the diffuser plate clean and are very effective in pulling water from along a muddy bottom, whereby lifting the gases to the surface and bringing dissolved oxygen back down.  Each diffuser plate comes with a back-water valve to prevent water from entering the airlines when the system is not running. The plate’s snowshoe like design allows the plate to sit level on the lake’s bottom and prevents it from sinking in muck. The self-weighted air lines and the diffuser plates don’t require anchoring which makes them easy to pull up for any required maintenance or for re-positioning if desired.
