HOW IT WORKS

  • "Eutrophication" is an excess of nutrients in water, causing over population by harmful organisms and a decrease in water quality.

  • Eutrophication often results in fish and bird deaths and makes water unstuitable for human use.

  • Nitrogen (as Nitrites, Nitrates and Ammonium) and Phosphorous (as Phosphates) are the two main elements that cause eutrophication in water.

  • Eco-craft Floating Treatment Wetlands use a number of natural mechanisms to effectively remove nitrogen and phosphorous from the water.

Nitrogen Gas

Ammonia Gas

Particulate Phosphates

Dense root zone and biofilms.

Sedimentation of nutrients on soil and organic particles

Nitrates and nitrites in solution

To Sediments

The activities of bacteria in the biofilm oxidise ammonium into ammonia gas.

Biofilms (microbes) cover the many roots

Particulate Phosphates attach to biofilm and settle to the lake floor where they form complexes with clays/ metals.

The dense root zone and biofilm create zones of anaerobic and aerobic conditions which facilitate de-nitrification.

The rate of settling of suspended sediments is increased by the action of roots and biofilms
