Quality aspects of the plants by Rota Guido

8. Continuous gas control;

For the control in real time if the biogas conditions and, therefore, the fermentation inside the digestors have proceeded properly, or otherwise it indicates about further and necessary intervention.

7. Gas treatment with cooling and final filtration;

The gas treatment with special filters at refrigerator cycle and active carbon offers the benefit coming from an almost total level of biogas purity, that turns into less oil changes and lower maintenance costs of the cogenerators.

6. Biological desulphurization with wooden roof;

The biologicas desulphurization inside the digestor through desulphuring bacteria has the advantage of reduce almost completely the sulphuric acid, while reducing also the costs of the remaining treatment through safety active carbon filters, protecting the engines and reducing the costs of service.

The pressure domes can be made in plastic material rubbed in doouble memebran and in patented elastomer material and in both cases they are equipped with safety systems and gas connection.

4. Riscaldamento con serpentine inox e/o PEOC;

The heating system has no connection inside the digestor but everything is on the external side, by means of special collectors. The functioning ensures the correct thermostating of the mass with insignificant variations for the aims of a perfect anaerobic fermentation both in mesophile and thermophile.

3. Mixing with Paddelgigant mixer;

The mixing system iso ne of the most important elements for a good fermentation. The Paddelgigant at horizontal axis and with blades of d. 3,7 m grants an homogenizing effect on the biomasses, with immediate breaking of the surface scab and improvement of the
formation and outlet of the biogas.

2. Loading of the solid fraction with special "Vielfrass";

The system loads every type of product avoiding any block, through a system of three screws, of which two are mixing screws and a big volumetric screw.
The storage container contains great quantities of product that is automatically taken by the system and recalled inside the primary digestor.

1. Loading of the liquid fraction with pumps and capacity controllers;

Allows the loading of the liquid fractions from various origins with dry matter content up to 10% by fixing the volume and times during the moments of the day, so to avoid thermal leaps to the bacterial flora.

ROTA GUIDO, THE SAFE AND RELIABLE PARTNER THAT KEEPS ITS PROMISES.

THE QUALITY ASPECTS OF THE PLANTS BY ROTA GUIDO

So you can rely on us during all the stages, from the research, the planning the realization and the start-up of the plant, up to the maintenance to the highest levels of efficiency and production.

Our personnel and our technical means are ad your full disposal, as we understand that only a perfectly running plant gives the best
performances and incomes.

Our technical team is always by your side both in the moment of the start-up and during all the following maintenance operations to keep your plant at the highest running levels. The final installation and the perfect result will be reached in the shortest possible time, as well as our care to help you with useful directions every time that it is necessary.

WE GRANT FOR THE RESULT

All the plants are equipped with a computerized system that controls the efficiency of the process in terms of quantity, quality and times of immission of the single products with a constant control – also in remote mode – of the single performances. All the production's level and the quality of gas are supervised, as well as the efficiency of the single components, the ideal parameters and the cogenerators' performances.

A COMPLETE RANGE OF PLANTS FOR THE BEST PERFORMANCE 
A complete range of cogenerator of different types and powers, offers to each customer the opportunity to realize a plant that meets perfectly with the specific situation of the farm.

CUSTOMISED PLANTS TO MEET WITH ALL YOUR NEEDS!

9. Gas lines and safety valves;

Collection and feed gas lines from the digestors to the cogenerators that, equipped with their safety valves, filters and gate valves, grant the correct balancing and the correct feed to the engines.

10. Inspecting glasses with light;

They allow the full and necessary visual control for the direct inspection of the level of mass, formation of foams or hair on the surface, the correct mixing and the formation of fermenting bubbles from the gas production.
In case of irregularity, it is possible to act with a quick intervention to restore the functional parameters of the plant

11. Biogas and bi-fuel cogenerators:

The cogenerators are the equipments for the transformation of biogas into electric and thermal energy.
Their performance level, added to the production level of biogas, give the best total efficiency and the best economic income.
Therefore it is essential to have a wide range of types, both biffe and only gas, so to adopt the most convenient solution on a technical point of view

12. Collectors for the thermal recycling;

They provide the proper hydraulic distribution of the thermal energy to the digestors, and they leave further excesses for subsidiary consumers or for plants that use at best the thermal energy in excess.

13. Transfer and for digestate unloading pumps;

The transfer of the digestate from the primary to the secondary digestor and from this to the following treatments and storage, is granted by single-screw pumps, fully reliable, that control automatically the different stages of the process through level probes.

14 Final separation treatments and potential nitrogen reduction;

Treatments to be carried out on the digested effluent to help its management in case of nitrogen excess compared to the surface of distribution, systems of nitrogen reductions can be adopted in order to remain i the legal parameters.
In particular, they are separation, flotation, nitro-denitro and stripping systems, depending on the necessary level of reduction.

These plants must be balanced according the specific needs of each farm or group of farms, to optimize the productivity and grant economical sustainability.

As previously reminded, biogas cannot be released in the air as it is a carbon gas much more dangerous than carbon dioxide. When it is impossible to use biogas, it has to be burned in flare.

There are different types of flares, essentially according to the combustion temperature, the presence in isolation and air feeding, with natural or forced ventilation.

OUR TECHNICAL TEAM IS AT COMPLETE DISPOSAL FOR THE BEST SUGGESTIONS AND TO BE CLOSE TO
YOU during the control of the correct energetic production of the single matrix used, the change of further substrates, the control of the correct fermentations, the optimization of the processes and efficiency, during mainteinance and service, during the development and enlargement of your installation.


The loading system of the solid matrix with volumetric screw for the immission under the surface and mixing screws is a crucial element for the efficiency of the installation. Reliable, low-consumption, fast to load, automatic in the management, helps the stabilization of the biochemical process and the productivity's increase. Different capacities from 10 to 100 m include brilliant solutions for the needs of your installation.
The mixing system is an absolute news and an essential element to grant the ideal productivity of your installation. Total reliability to avoid any intervention inside the digestors means no necessity to stop the plant and so no waste of time and money.
