MABR technology may help to upgrade Italy sewage treatment mode

Italy Borghetto Church of the Holy Spirit - a tourist attraction managed by SPA environmental services company. It has been a 10-month neutral wastewater treatment pilot site, has been in the first 6 months has achieved good results.

In order to increase the number of plants with a daily processing capacity of 30,000 m3 / day, SPA Environmental Services has launched a pilot project since December 2016 to see if the Zee Lung Membrane Aeration Biofilm Reactor (MABR) How much energy is saved.

The pilot also tested GE's first improved LEAP primary treatment technology for GE Water Technologies. At the same time it has been established as a pilot plant for the MABR process test.

Within six months of the start of the pilot project, Zee Lung's MARB technology has shown its potential for energy neutrality. Including the following:

Compared to fine bubble aeration energy 4-5 times;

When the same emission limits are reached, 50% of the biomass is saved compared to conventional activated sludge processes;

Up to 80% nitrogen removal can be achieved without internal nitrogen cycling.

SPA Environmental Services will continue testing the GE Water Treatment Company's equipment at the pilot before the summer of 2017.

So far, Zee Lung technology has demonstrated the use of only 2 meters of water level can be achieved up to 40% of the oxygen conversion rate. In contrast, the traditional fine bubble aeration system efficiency is only 6-8 percentage points.

In addition, due to the simultaneous nitrification-denitrification reaction in the Zee Lung reactor, the pilot is studying the denitrification process parameters.
The following are the same as the "
"In the ongoing pilot project, GE Water Technologies' unique solution helps us to understand the ability to increase water treatment and eutrophication while not expanding space and reducing energy consumption," said Giovanni Paolo Paganelli, general manager of SPA Environment. This helps to control costs and improve operational efficiency, making the plant better and more economical to run.

"SPA environmental companies are really leading the way for future wastewater treatment because they are able to achieve energy neutrality and see that our Zee Lung MABR technology is helping them to increase their energy consumption while increasing their energy consumption," said Chris Jeffery, Global Sales Director, GE Engineering. The goal of denitrification is really exciting, and it turns out that the pilot project is working very well. "
