ecuador; biohaven; streambed; guayaquil

VITA Water Tech (Lethbridge) installed 4,200 sq ft of BioHavens and two streambeds in an estuary in Guayaquil to decontaminate the heavily polluted water from sewage. After 6 months the estuary was safe to swim again and marine life returned.   In contrast to the installation picture (July 2017 - see below) the aerial picture taken July 2018, shows how the plants have prospered. The floating treatment wetlands (FTW) comprise plants, an extreme high surface area of the BioHaven matrix for the development of a biofilm and a streambed; all together they are a powerful tool to remediate water bodies. A streambed is an 'active' BioHaven that incorporates forced waterflow and aeration, improving greatly the performance of FTWs.

BioHaven; floating treatment wetland, FTW, floating island

In certain locations with extensive waterfowl populations such as Canada geese, the young plant plugs initially installed on the floating islands are vulnerable to destruction by these types of birds. In one pond close to the Lethbridge (AB) airport the plants were struggling for the first season until the second season when we installed the protective cages as seen on the picture. Since then the plants have been thriving.  The cages are made of conduit and chickenwire and blend in the landscape. After that vigorous growth, the plants are strong enough to resist plucking by the geese. If desired, cages can easily be removed.

BioHaven floating wetland, island, wastewater study

The University of Calgary conducted a two year study on the effects of floating treatment wetlands (FTW) in a wastewater lagoon. The study  sponsored by Alberta Environment & Parks and Environment Canada demonstrates that FTWs remove naturally and effectively contaminants from a wastewater facility. This study focused on the fate of phosphorus, nitrogen, organic carbon, and suspended solids, as well as the change in water temperature, pH, electrical conductivity and dissolved oxygen. All of these parameters can have a negative impact on water quality, if not managed properly. View a summary here...of the master thesis highlighting the convincing results and the poster here...with layout of the on site tests.

Wetland Plants are blossoming on the floating islands at the wastewater test facility

July 07, 2016

Thriving wetland plants on BioHaven floating island at wastewater test facility

The sedges and rushes planted as small plugs about a year ago (see news below, June 2015) on the BioHaven floating treatment wetlands (FTW) are now flourishing and doing their 'work'. The rigorous research project led by the University of Calgary using floating wetlands in wastewater from the Carseland, Alberta, lagoons is clearly demonstrating the effectiveness of this natural ‘technology’. Contaminants such as phosphorus, ammonia, nitrate, total nitrogen and BOD are significantly reduced.

This passive technology requires no maintenance, is long lasting and therefore more cost effective than other systems. The BioHaven floating treatment wetlands can reduce the required space for new lagoons, can retrofit existing lagoons to increase their capacity or ensure non-compliant lagoons to improve their parameters.

BioHaven floating island wetland with biochar Lakeland College

Lakeland College in Alberta launches an experiment  to assess the use of biochar as a soil medium on floating islands. However, water sampling and testing was carried out for the duration of this experiment to measure nutrient loads in the water as well. Regarding soil mediums, coconut coir is a popular choice in floating islands as it is a readily available and relatively inexpensive natural product derived from the coconut husks during processing. Biochar is a solid, carbon-rich product derived from the pyrolysis of waste biomass, typically forestry or agricultural residues. This experiment aims to determine whether or not biochar is a suitable soil medium alternative to coconut coir.

Joint Venture Announcement with Clearflow Enviro Group

October 10, 2014

Clearflow Enviro Systems Group

VITA Water Technologies and the award winning Clearflow Enviro Systems  Group have entered a Joint Venture to provide an integrated solution to improve and maintain water quality in stormwater ponds.  Clearflow technology addresses soil and water challenges.  The technology separates suspended and colloidal pollutants, metals and toxic materials from water prior to entering the pond. The Clearflow technology in combination with BioHaven floating islands extends the life of stormwater ponds through reduction of sediments at the inflow.  Maintenance costs for sediment removal are also reduced. For new ponds, the combined technologies enable a reduced pond footprint and a resulting lower investment cost. From an environmental perspective, the greatest overall benefit is the long-term health of the pond.

Floating Islands in Taber pond; School science project

September 12, 2014

Taber Pond

Students from Taber Christian School helped prepare and launch several BioHaven floating islands in the pond of a new housing development. Vita Water Technologies of Lethbridge, worked with students to establish a science project that will involve periodic water testing to gauge the islands’ effectiveness in improving water quality.

“I think every school kid in Alberta should do it, or Western Canada or North America, where instead of complaining about the environment, you go out there and learn what’s going on with our water,” Sid Tams, owner of the development  said as he watched students prepare the islands. “This is the future of storm water. You can’t just run it into the river.” Cory Armfelt, Taber’s director of planning and economic development who also watched the launch, said the town supports the concept of a floating laboratory for students. “It seems more holistic to treat water like this,” said Armfelt.

Olds College is interested in verifying the survival rate of the Horsetail plant (Equisetum fluviatile) on BioHaven floating concentrated wetland. In the previous season the Horsetail plant had a 100% failure when installed on the pond shoreline. The Horsetail plant seems to be excellent at absorbing heavy metals as present e.g. in tailing ponds of oilsands extraction facilities. To date,  mid September  2014, the plants on the BioHaven are thriving. Olds College has an extensive wetland research facility with 19 different ponds. The water quality of each pond is remotely monitored in real time for 13 variables.
