Components specification
| Vacuum generation block - n° 2 liquid ring ( anello liquido ) vacuum pumps - aspiration flow rate: 200mc/h at 213 mbar - installed power: 5,5 kw with 4 poles - n° 1 recycling water tank made of zinc plated steel, painted, 300 litres capacity, with upper inspection flanging |
 |
Liquid collection and discharge tank Preset for direct lying underground, sized to resist to an internal depression of – 100Kpa, entirely made of stainless steel AISI304, with the following features: - Capacity: 7mc - Diameter: 2360 mm - Thickness: 6 mm - Height: 2100 mm N° 2 underwater electro pumps with the following features: |
 |
| Depression pipelines The pipelines net are always under a constant internal level or relative negative pressures of about – 40/-70 kPa (-4/-7 m.c.a.). The vacuum pipelines create a completely sealed circuit; the material used is high density polyethylene (PEAD) PN6-10, with specific accessories that grant operationality to the implant. The high density polyethylene's flexibility grants the realization of the project profile without any special additional parts. |

Interface traps - capacity: about 600 litres - flow rate: 120 l/cycle (adjustable) - material: PEAD - curb box: spheroidal cast iron D400 UNI-EN 124 class - size: int. Diameter 700 mm, height 1500 mm. - users drainage: N° 3 antiextraction joints D= 125 mm - vacuum net: N° 1 pipe D= 75 mm Pneumatic components - PVC PN10 aspiration block - D63 mm – 2” pneumatic valve - floating activator Operational conditions It's good to estimate during the sizing process that a trap works an aspiration cycle every hour (120 litres x 24 cycles/day) for a total flow of 2900 l/day, for this reason the project will consider a trap every 12.5 inhabitants (2900 l/day : 230l/inhabitant) |
