Impressive results for Indian lake restoration with Canadianpond.ca’s Bubble Tubing

This is the case study of the restoration of the hyper-eutrophic Pushkar lake in India, via CanadianPond.ca’s ¾” micro bubble tubing following the fish kill of September 2008.  This case study was provided by our client Randhawa Brosons Enterprises whose project it was.

Pushkar is a small town of about 14,000 people.  The total size of the Pushkar Lake is 4.5 hectares, and was about 2 meters in water depth until reaching the start of the 1 – 2 meters of benthic muck in 2008.

Pushkar Lake's fish kill of 2008

Pushkar Lake’s fish kill of 2008, before aeration

Pushkar Lake is one of the most sacred lakes of the Hindu Religion. Pushkar Lake finds mention on coins as early as the 4th century BC.

Being that Pushkar is one of the oldest currently inhabited cities in India, it is safe to reason that organic offerings have been made into the lake for thousands of years. Thus, the solution had to be engineered to deal with over a meter of organic benthic material that had accumulated over centuries, without stirring it.  If stirred it would have drastically reduced the already poor water quality.

To create a solution that would dramatically increase the Dissolved Oxygen while not churning the benthic material at the bottom of the lake, 600’ of CanadianPond’s ¾ inch micro bubble tubing was used as the main technology.

Pushkar Lake – After aeration (Jan. 2009)

Post Aeration, we received no reports of the usual people falling ill after drinking the water or bathing in the lake. More so, the visibility of the water cleared up dramatically after a few months, to where one could see the sandy bottom; whereas, before aeration one could not see an inch into the water due to pollution and cyanobacteria. The local people, priest, pilgrims, and

tourist all enjoyed the newly aerated Pushkar Lake, as it did not smell of sewage, nor did it smell anaerobic digestion as clearly stated in the appreciation letters.

You will find in this amazing case study :

  • Full presentation of the project and history of Pushkar Lake
  • Parameters of the water quality before aeration
  • Description of solution and products
  • Before and after pictures
  • Test results reports
  • Appreciation letter from the government, the Municipality Customer and the Congress Party

Orca whales and the power of social medias

Killer whales in Inukjuak

As I opened the most recent edition of McLeans magazine, in which there is a review of the year in pictures, I caught my breath as I saw a stunning double-page pictures of the pod of orca whales who found themselves trapped in ice last January in Inukjuak, Quebec.
It reminded me of how closely we were able to follow this story, practically minute by minute, over a short period of 24 hour, through our social media accounts.

We saw firsthand the power of social media to bring people together, contribute support and ideas and share up to the minute updates on a situation that was close to their hearts, and ours!

Let’s recall what happened then…

January 9 2013– Afternoon

A post appears on our Facebook news feed stating that a small pod of orca whales seem trapped by ice sheets somewhere in Northern Quebec. As the evening went on, it quickly became evident that in their efforts to keep the hole from freezing over, the orcas whales were putting themselves in danger of exhaustion. The only breathing hole for the orca whales was the size of a large pick-up truck.

January 9 2013 – Early evening

Big Miracle movie poster

Remembering a similar situation that occurred in Alaska in 1988 (on which the movie A Big Miracle was based, see poster), where grey whales trapped between ice sheets were rescued with the use of deicers. Being based in Quebec ourselves, the president of our company, Mario Paris of Canadianpond.ca, decided to directly contact the mayor of Inukjuak to offer him help in the form of water circulators, bubbler systems and staff. Petah Inukpuk kindly took note of the offer but had to meet with town officials before taking any decision as to the course of action.

January 9 2013 – Late evening

Following the meeting, it was decided that Andy Moorehouse from Air Inuit would coordinate the efforts. So we also offered our help to Andy. However the decision was made to wait a little longer to intervene as nature might just take its course. On the advice of the Elders based on traditional knowledge of wind and ice shifting patterns, it was their hope that shifting winds following the moon cycle might create a break in the ice allowing the whales to escape to freedom.

January 10 2013 – Morning

Anxiously awaiting news to find out if we should organize the shipment of our deicers and linear bubblers system, we kept our eyes on our social media accounts where we were stunned to see the outpouring messages of support and the fast sharing of any information in the form of pictures, videos and updates. At around 9:30 am the following day, Mayor Petah Inukpuk confirmed in a phone message that the whales had left the area and were on the move early in the morning. Instant relief for everybody was quickly followed by more worries as the whales’ troubles seemed to not be over. There was roughly 1000 km between the pod and open Atlantic water, and people were still concerned for their safety as the ice cover was shifting and growing.

January 10 2013 – Afternoon

An aerial survey from Inukjuak revealed no trace of the orca family that had been trapped in the ice with just one small breathing hole.

In the next few days, more aerial surveys were conducted and they confirmed the whales somehow managed to find their way to safety.

Facebook messageSuch situations where whales get trapped by ice may be more common than we think but this case received a lot of attention as it was so close to a village. It would be unrealistic to hope this won’t happen again, but if it does, our deicers and bubbler systems remain available. We’ll keep our eyes peeled and if you hear about it first… …just send us a Tweet, and we’ll be there!

3 Bubble Tubing™ International Distributors

Bubble Tubing™ linear aeration tubing now has distributors globally.

Our distributors offer our excellent Canadian made bubble tubing diffuser for waste water aeration, bubble curtains, lake aeration, river and canal restoration, sound wave attenuation, mixing and deicing.

1. Randhawa Brosons Enterprises is our distributor based in India doing wetland, lake and river restoration.

Pushkar Lake in 2008

Pushkar Lake in 2008

Canadianpond.ca has developed a long standing relationship with Randhawa Brosons Enterprises who, since 2008 has been our sole distributor of Bubble Tubing in India. They have worked tirelessly to improve surface waters in India, specializing in restoring India’s lakes, rivers, canals and sacred sites. Eliminating the need for expensive dredging in many lakes by using aeration to quickly and efficiently degrade decades of accumulated organic sediments, is the way to go in a country facing polluted waters like India. Convincing officials that aeration saves money, saves time, improves water quality, increases basin depth without harming lake bed morphology, and helps purify water, should be easy as the public and the politicians want India’s waters to be the best they can possibly be. Here are some examples of how aeration with Bubble Tubing has helped Indian waters:

  • Improving water clarity for bathing and drinking in a Buddhist temple where every day, the monks feed bread to the catfish . Aeration plays an important role in pathogen reduction.

    Pushkar Lake - After (in Jan. 2009)

  • Water clarity, increased visibility in many rivers and lakes after aeration. Currently there are several large bodies of water where water clarity has climbed from 0 to over a metre within one year of installing aeration systems using our Bubble Tubing technology:

    “This lake gets sewage from time to time, and only gets 8 hours of electricity a day. Regardless of those problems, it has gone from opaque to 44 inches of visibility. And we have not heard of any of the temple bathers getting sick after their “holy bath” and this only a few months after install.”

  • Aeration has reduced algae, coliforms, odour and increased water quality, allowing indigenous species to thrive in previously polluted waters (Lucknow project).
  • Rejuvenating some larger iconic lakes of India.  Randhawa Brosons Enterprises have proposed Bubble Tubing for dozens of projects, all awaiting proper approvals.  Not being deterred by the difficulties involved in improving the environment in India, our partners keep pushing ahead.

3. Coastworks serving Scotland and the UK uses the bubble tubing to create bubble curtains on the sea floor.

Bubble curtains such as those used by Coastworks are an excellent way to:

  • Prevent marine life from entering underwater blasting sites;
  • To block jellyfish from nuclear power plant intake pipes;
  • To attenuate wave and blast effects;
  • To protect marine wildlife from the hazards of marine construction.

Watch Coastworks video: Coastworks designed and installed a “bubble curtain” around the cooling water intakes at Hunterston Power Station. The bubbles prevent jellyfish from being sucked into the intakes and blocking the filters by “blowing” them gently to the surface.

Canadianpond.ca is our home base and where we designed Bubble Tubing™. We supply our distributors and clients in industry, government, commercial and private clients. Contact us or our distributors for information on Bubble Tubing™.

Discover 5 New Applications for Bubble Tubing™

Undersea fine bubble wall

Jellyfish blocked from water intake pipes by Bubble tubing fine bubble curtain

In water, air bubbles reduce transmission of noise. A simple curtain of bubbles (a line of bubbles that rise to the surface from our weighted linear bubble tubing installed on the sea floor) in a marine application limits the propagation of sound waves and the effect of undersea blast shock that can harm marine life. Also known as Bubble Screen, Air Curtain, or Bubble Plume, the applications that require a bubble curtain are numerous:

In France, the École Nationale Supérieure de Techniques Avancées (ENSTA, Brittany) has developed Masters and PhD level projects around these issues using our Bubble Tubing™; see article Bubbles to dampen sound (available in French only) . However, this application for Bubble Tubing™ is still rather unknown here in Canada. Understanding more about wave and sound attenuation using bubble curtains would certainly make an interesting study for Canadian university students in the fields of marine biology, oceanography or environmental sciences.
Made in Canada since 2003 by Canadianpond.ca Products Ltd and primarily designed for aeration applications (see quotation below) and de-icing, bubble curtains made with Bubble Tubing™ have an enormous potential that warrants further research, toward the protection of the environment and marine life.

Industrial deicing: At Canadianpond.ca we are serious about bubbler deicing!

Deicing technologies involve the physics of water and the blending of specific gravities in relation to water temperature (calories) and depth.  In the video below, the OctoAir-10 diffuser (with our proprietary Bubble Tubing embedded in the industrial grade, stainless steel, weighted base) is used to demonstrate an industrial deicing installation.  As the bubbles are released from the OctoAir-10 on the bottom of a lake, they help lift up the dense, heavier and warmer  water (usually 4 Celsius) to the surface, creating a constant vertical lift to the surface water.  This continuous current in effect pushes the colder water away, helps melt or weaken the ice cover and prevents new ice formation.  Once the energy of the current is released, the somewhat warmer and heavier 4 Celsius water sinks back on its own by gravity to the bottom in an endless deicing loop. The size of the hole being deiced is affected by: the quantity of calories in the water, the water depth and the ambient air temperature, as demonstrated in the video. Thawline deicer Imbedded in the OctoAir-10, is our proprietary bubble tubing (pictured below in blue). Bubble tubing can also be laid in a linear fashion (as along a mining wharf) in order to de-ice around or through structures, around boats or barges, submerged walls or wherever ice formation is undesirable. Bubble Tubing is available in 1 ¼”, ¾” and ½” I.D. In many installations, bubble tubing for deicing has saved thousands of dollars in operational costs and extended industrial operation period long into winter where it was not possible before.

Thawline Bubbler or Kasco Deicer? That is the question!

Fall is upon us, but we have delayed discussing and planning how to protect the new dock at the cottage from the ravages of winter ice.  I know we have choices of an impeller type system de-icer from Kasco, that can be suspended from the dock or a linear deicing bubbler like the Thawline system. I have contacted Canadianpond.ca, the company I trust most for advice on aeration, bacteria and now for deicing.Deicers at CanadianPond

If I go with a Kasco de-icer, we could suspend it from the end of the dock because it is fairly deep there, and it will keep a nice sized hole in the ice all around the structures we want protected. I like this option because installation will be easy, cost to run the unit is low and my neighbor has one and likes it.

But I have another choice with the Thawline deicer that uses Bubble Tubing. I really like this option because we can leave it in all year and it will help keep the muck down where we swim. The problem is the slope; it is very steep at our shoreline. I would rather install this when the water is warmer, that way I can make sure the tubing all goes in at the same depth. Thawline is also easy to install, it is affordable to purchase and operate.
