As an alternative to the Vacuum system with prefabricated raceways we realize sewage evacuation systems with buried underground lines adequately sized and made up of pipes and T-fittings for the discharge of sewage.
We pay particular attention to the type of pipes and fittings used to ensure correct operation and long life. Therefore we use heavy components with high thickness and equipped with gaskets, contrary to what is often seen on the market.
MANURE EVACUATION CHANNELS
We produce various types of prefabricated channels in R.C . for the conveyance of sewage from the pits. A correct sizing and positioning of them guarantee a complete evacuation of the sewage from the sub-pit thanks to the vacuum discharge operation.
1. Useful dimensions: 0.70 x 0.26 H. With any Ø200 / 250/315 hole.
2. Useful dimensions: 0,57 x 0,26 H. With any Ø200 / 250/315 hole.
3. Useful dimensions: 0.50 x 0.15 H. With any Ø200 / 250/315 hole.
We realize prefabricated tanks of different sizes and types for different uses in breeding farms. I can be monolithic if small or composed of more elements if larger.
On request they can also be equipped with a rigid floor.
Can be used for the collection of sewage sectors from warehouses (such as storage backup) before th relaunching in the storage tanks and in separation or nitrogen treatment plants.
They can also be used to receive the exhausted manure from storage tanks through automatic valves with working with float that allow the extraction by tankers without forcing the operator to get off the tractor.
We produce solid-liquid separation systems for sludge from farms through the use of screw separators designed to last over time.
It is made of stainless steel and cast iron with 5.5HP motor (kw 4.1) 400V 50Hz, stainless steel micro-slit filter, stainless steel compression cochlea with hard metals and provided with cleaning brushes and mechanical system of compression of the separated solid at counter-weight.
Because of the new regulations and the increasing nitrate density of farms and biogas plants is increasing the number of farms that do not have enough land to be able to use all its waste as fertilizer products.
When the amount of produced manure exceeds the disposal capacity of the soil, it takes the form of contaminant. The action you have high pollutant content of nitrogen and organic matter is biodegradable and is manifested by the passage of wastewater into surface water via direct discharge or leaching into the groundwater.
To solve these problems we propose a pre- treatment plant with biological nitrification and denitrification to the nitrogen present in the manure, in order to allow farmers to spread on their land slurry that, reducing nitrogen up to 70% , will require less than a third of the fields which would not need this type of plant.
The proposed plants use natural biological reactions, without any chemical additive and operate with the utmost simplicity.
We produce rectangular liquid manure storage tanks with heights up to 4 meters. The prefabricated panels rest on continuous cast-in-place foundations; the tightness of the joints between components is guaranteed not only by elastic sealants resistant to chemical attacks, but also by an anti-shrinkage concrete filling placed in a special seat between the panels. The concrete used for the manufacture of prefabricated components is in exposure class XA3 and is resistant to liquid manure chemical attacks: this guarantees durability over time. The use of prefabricated components allows accurate and timely monitoring during the production phase, and allows building the tanks in a very short time compared to those made on site.
Our prefabricated circular tanks are made of reinforced concrete with walls up to a height of 8 meters and with a flat or lowered bottom. We adopt an innovative system consisting of prestressed prefabricated panels positioned vertically that rest on continuous foundations created on site; the assembly of the walls takes place through the use of harmonic sheathed strand steel which, after being post-tensed during assembly, acts as a “belt”. This construction system makes it possible to have more streamlined walls and foundations in absolute safety, and therefore to reduce the cost of construction compared to the tanks built on site. The hydraulic seal is guaranteed by a long series of measures and accurate technical choices. The walls are produced in the factory with concrete C40/45 in exposure class XA3, in a controlled and managed environment in full compliance with current product standards and certifications.
