Extrusion International USA 4-2020

44 Extrusion International 4/2020 PIPE EXTRUSION a frequency variator and the other will be equipped with a variable fre- quency modulator capable of doing the same from the direct current of photovoltaic solar energy. Filtering equipment: Consisting of 2 batteries of 24 units each of self- cleaning 3 “ring filters with a 100 mi- cron pitch, or equivalent system that must maintain a filter surface of 24.24 m 2 , all on polypropylene collec- tors of PN10 and 300 mm diameter or of material of equal or better reli- ability. E. Bombeo Building: The pumps and the filtering equipment will be housed in a building with a 25x10- meter metal structure on the ground floor, vertical enclosure using a pre- cast reinforced concrete panel and a metal sandwich-type roof. Power supply: The grid power sup- ply to the EB will be made with a 312.2-meter medium-voltage over- head line, a medium-voltage under- ground input line to the 400 KVA compact outdoor type transforma- tion center (CTIC). of power, and low voltage installation. The photovol- taic solar energy supply will be made from an isolated ground-based plant of 594 panels of 300 Wp, with a pow- er of 178.2 kWp, which will be able MOLECOR ® molecor.com/en Filtering station. The filter station will consist of 4 batteries of 32 units of 3 ”self-cleaning ring filters with a 100 micron pitch, which must main- tain the filter surface of 64.64 m 2 and will be equipped with a wash water recovery tank to its subse- quent injection at the inlet of the filtrate, by means of an impulsion electric pump. The electrical sup- ply for this filtering station will be made through an isolated roof pho- tovoltaic solar plant, made up of 40 panels of 300 Wp and a power of 12 kWp. Transfer pipeline between the regulating reservoir of the sector of the present project and that of sector 1, 1,924.50 m long, made up of PVC-O pipes of PN12.5 diameter 400 mm. Automation: remote units will be used to control hydrants and valves, which will communicate with con- centrator units (one in the delivery area and the other in the gravity area) via radio. Conclusions Molecor manufactures Oriented PVC (PVC-O) pipes and fittings ap- plying ecodesign, achieving pipes with a very high useful life, reduc- ing the consumption of natural resources, both raw materials and energy during its manufacture, thanks to the development of a new very energy efficient manufac- turing technology. to provide 257,570.2 kWh/year annu- ally, with a use of 54,7% of the total annual production, on the energy to pay if all of it came from the grid. The plant will also have a system to store energy with stationary batteries, with the capacity to deliver 450 kWh/day. Hydraulic networks: • Branched distribution network of the Impulsion Zone of 8,190.2 m in length and diameters between 400 mm and 90 mm, in PVC-O series 500 and HDPE (PE-100). • Distribution network of the Grav- ity Zone of 21,778.35 m in length and diameters from 800 mm to 90 mm, with the following materials: PVC-O series 500 and HDPE (PE-100). • Connections: They are projected in high-density polyethylene (HDPE or PE100). • Collective and individual hydrants: 41 will be installed in the delivery area and 98 in the gravity area. There are a total of 371 in the delivery area and 868 in the gravity area. • Tertiary pipes: will be in charge of carrying the water from each individ- ual hydrant to each parcel or farm. They are projected in HDPE with di- ameters between 32 mm and 250 mm with an approximate length of 179 km.
