SNIT is the key technology for low-carbon and clean wastewater treatment

Unconventional method for treating municipal wastewater leads to positive environmental impact.

The four stage project’s aim is to take one more step towards self-sufficiency of wastewater treatment plants.

SNIT results in cleaner wastewater treatment

Considering global challenges of environment protection the project addresses interdisciplinary problems. Shorter nitrogen path removal from wastewater means longer life for planet Earth.
O 2

Reduced oxygen demand

Up to 30% lower energy consumption in nitrification process

O 2

Increased biogas production

Lesser demand of denitrification for organic compounds lead to enhanced methane production

Clean rivers

Significantly lower concentration in wastewater treatment plant effluent

Shortcut nitrification in mainstream – fresh perspective on wastewater treatment

Abstract

Water and energy are popular topics around the world, due to the difficult environmental situation, as well as growing concerns about global warming. One place where these two resources are inextricably linked is the wastewater treatment plant. Improving the quality of treated wastewater is usually achieved through increased energy consumption – e.g. for raising the oxygen concentration in the reactor, or capital expenditure – e.g. for an external organic carbon dosing installation. At the same time, it is routine at larger facilities to produce energy from the combustion of methane gas generated in the sludge digestion process. The SNIT project, addresses both issues and aims to improve the quality of treated wastewater and increase digester gas production with moderate investment. The key to this is the use of nitric acid to induce partial nitrification in the main-stream, as well as to disintegrate the sludge to increase the organic load, which is the substrate for the fermentation. By removing nitrogen via nitritation, the consumption of oxygen and organic carbon in the biological reactor will be significantly reduced, and the shortened denitrification will allow for deeper nitrogen removal.
