Mogi Mirim receives solar energy in sanitation

On Thursday (25) The first solar power generation system in the country's sanitation sector, the ETE Mogi Mirim photovoltaic plant, SESAMM (sanitation services of Mogi Mirim), the fruit of a consortium formed between SABESP, GS Inima Brasil, was started in operation. and ECS operations. As one of SESAMM's proprietary companies, SABESP will be able to bring the technology of the plates from China to other units.

"It is an extremely important partnership for Mogi Mirim and I am sure that Sabesp's presence in the SESAMM consortium brings great benefits to the population. We will gain even more quality for the sewage treatment of the municipality in the coming years, "said the mayor of Mogi Mirim, Carlos Nelson Bueno.

"The environmental impact of the inauguration of the photovoltaic plant at ETE Mogi Mirim is extremely positive, as we use clean and renewable energy. In this way, we will contribute to a more sustainable community and to a more responsible production and consumption. The project will serve as a benchmark to be replicated in other SABESP stations in the state, "said the superintendent of research, technological development, innovation and new business, Cristina Zuffo

"With the installation of the new technology we intend to bring even more sustainability to the unit, because we already have the service of reuse water and LED lighting in the facilities. With the installation of photovoltaic panels we will supply 30% of the energy supply, benefiting even more the station in this aspect ", stressed the CEO of SESAMM, Carlos Roberto Ferreira.

"Since the beginning of the partnership between SABESP and GS Inima Brazil, in 2008, there have been many advances. This time, we did technical studies on clean energy that pointed to the photovoltaic system as the most suitable for ETE Mogi Mirim. It is a great model, which will serve as an example for other regions of São Paulo, "said the president of GS Inima Brazil, Paulo Roberto de Oliveira.

Clean energy

The clean energy is produced from the solar radiation in contact with the 1,066 modules installed on the roofs and around the station. Silicon panels capture solar energy and convert it into electrical energy, meeting all ANEEL requirements. The plant produces 606 MWh (Mega Watt per hour), supplying 30% of the general electricity required for sewage treatment.

Currently, the station is capable of treating 150 liters of sewage per second and relies on prolonged aeration activated sludge technology. The investment in the Fotovoltáico system is R $1.8 million, fully realized by SESAMM.

The PERC Cell technology (Passivated Emitter and Rear Cell, or passive emitter and rear cell) has greater efficiency, resulting in a reduction of area occupied by photovoltaic modules and a more efficient generation of energy.

In operation since 2012, ETE Mogi Mirim is 100% automated and uses the Orbal Siemens surface aeration System, which provides the equipment shutdown at peak time, reducing the operational cost of the ETE. The station does not use drinking water in its processes, since all the water used is reuse water produced at the station.
