Boudreau Pump Station

Promising results from the Chatham site

A phosphorus removal and recovery system being tested at a municipal pump station west of Chatham is showing promising results after less than a year of data.

 

“We’re confident in the technology because the data shows that it is working,” says Chris Jowett, Head of Technology & Government Relations at Waterloo Biofilter Systems Inc. 

 

The company is using a patented technology called the Waterloo EC-P™ that has been successful in extracting phosphorus from sewage wastewater.

 

A shipping container has been installed at the pump station. Inside are several tanks – two for settling out the solids and silt from municipal drain water and a third that contains electrodes made from iron between which a low voltage electrical current is passed.

Medway Creek

December 2019 Update

Site:

A 100-acre farm in row crops with a tiled field. It has a small barn that is used for wintering 20 head of beef cattle. The test site is at the northeast corner of the property where a single tile delivers water through the small pasture to Medway Creek.

 

Partners:

Upper Thames River Conservation Authority (UTRCA) will be responsible for the site and the Thames River PRC will provide research and weather data support.

 

Research description:

A capsule containing a combination of crushed stone and slag (leftover material from smelting metal) will be inserted into the tile to capture phosphorus (P) from the water that flows out.

 

Water will be sampled before insertion, and the UTRCA will take samples at regular intervals, and especially after major rain events.

Amprey: A New Way to Remove Phosphorus from Agricultural Water Sources

The Ontario Federation of Agriculture (OFA), through the Thames River PRC, is working with the University of Western Ontario (Western) and Muddy River Technologies Inc. to determine how a new technology can remove dissolved phosphorus from a number of water sources.

Muddy River’s  technology is called “Amprey”. 

 

It uses electricity to dissolve particles to form hyper-reactive charged metal ions that attach onto phosphorus and remove it from water. The solid that is formed contains phosphorus and magnesium and can be used as a fertilizer for agriculture rather than being sent to the landfill as waste. The Amprey technology is being tested at a London site with access to Medway Creek.

Woodstock

Site:

A 70-acre farm with vegetable, row crops and alfalfa. Crops are rotated based on strips used for strawberries and other green vegetables. In areas other than the vegetable growing area (e.g. hay, corn, soybeans), manure is applied annually. The farm has a municipal drain on the property with three blind inlets.

 

Partners:

GAPS is responsible for installation, sampling and monitoring through Honeyland Ag Services.  The Thames River PRC will provide sample result compilation under the supervision of the Ontario Ministry of Agriculture, Food and Rural Affairs.

 

Research description:

One of the municipal blind inlets drains about 50 acres in an alfalfa field. In this test, an inlet cover is equipped with five Hickenbottom intakes which contain MetaMateria, a sponge that absorbs phosphorus (P), through which water infiltrates.
