Waste water purifier, Rozzano

by
The Rozzano wastewater treatment tanks of the Rozzano wastewater treatment plant are made of the waterproof structure Drytech White Tank.

Water treatment tanks represent a double challenge for waterproofing systems.

This type of structure must in fact guarantee double impermeability: to the external water table and, obviously, to the water treated inside the tank.

The Rozzano Purification Plant is also located on a narrow strip of land between the southern course of the Lambro river on one side and a canal on the other, in the south-east area of ​​the Smeraldino Oasis.

So the theme of the watertightness of the work is, if possible, even more sensitive due to the environmental implications.

Made by the Intesa Costruzioni company in collaboration with Drytech, the new purification tank was built in just 120 days with the Drytech Tank system.

The waterproof concrete was formulated by Drytech Engineering based on the characteristics of the system chosen by the construction company, with the aim of ensuring, in addition to watertightness, chemical resistance to urban waste.

Similar resistance is obviously required for DRYflex resin, which, being expanding, waterproofs joints, cracks and crossings by pressure.

The resin is injected along the entire thickness of the structure, so it opposes the water with a corresponding barrier.

Furthermore, the compatibility of DRYflex with drinking water – certified by compliance with BS 6920-1: 2000 – allows for guaranteed use in structures in contact with drinking water.

The new tank of the Rozzano Purification Plant, which came into operation in February 2019, has a capacity of 1,700 m³ and treats a maximum flow rate of 360 m³ / h.

Sant’Anna Hospital, Como

The new Sant'Anna hospital in Como is located on an area of ​​over 80,000 m² south of the city of Como and a few hundred meters from the headquarters of Drytech Italia.

The new Sant’Anna hospital in Como is located on an area of ​​over 80,000 m² south of the city of Como and a few hundred meters from the headquarters of Drytech Italia.

The Como Polyclinic has two underground floors exposed to a 2-meter flap, which will also house the operating theaters.

The waterproofing was carried out with the Drytech Tank System which, among other things, due to its construction characteristics and organization, ensured a significant reduction in days in the overall construction site budget.

The activities of the Drytech Tank System, in fact, are parallel to the others of the construction site so that, in fact, the waterproofing item has been removed from the work calendar.

To support the weight of the structure, the site of the construction site was consolidated with approximately 4000 reinforced concrete poles, with a depth varying between 20 and 30 meters.

The poles were thrown into shirts driven into the ground with micro-explosions.

The conversion of the industrial port area, west of the Genoa airport, also involves the construction of the Borgo alla Marina residential complex.

The conversion of the industrial port area, west of the Genoa airport, also involves the construction of the Borgo alla Marina residential complex.

200 prestigious apartments, with relative berths and garage, overlooking a new tourist port.

Under the buildings and the square, in direct contact with the sea water, the covered parking for residents is built with the Drytech Tank System.

City by the Sea, Savona

The residential center La Città sul Mare in Savona, in fact, heats up in winter and cools down in summer by exploiting the sea temperature.

The residential center La Città sul Mare in Savona, in fact, heats up in winter and cools down in summer by exploiting the sea temperature.

Excellent news for the sky arrives from the sea.

The plant is zero-emission and, using a renewable and free resource, provides a definitive solution to the problems of atmospheric pollution and the soaring costs of fossil energy sources.

The Savonate housing complex was built by Meraviglia Spa of Bulgarogrosso (CO) and was designed by the Technion Srl and Ellevi di Lecco design studios.

The 120 apartments are served by a heating system connected to a sea outlet, built on the boulder pier facing the complex.

The basic principle of the system is the substantially constant temperature of the sea water (about 18 ° in this stretch of coast).

The pipes of the heating and air conditioning system from the building run underground to the sea intake, where the heat pump is located, which uses sea water as a source or as a heat sink.

The transport of thermal energy takes place through the same water. Water that is sucked from the sea, brought up to the heat exchanger and, therefore, released.

The system has a positive energy balance: it supplies more energy (heat) than electricity needed for its operation (the ratio is at least 1 to 4 or higher, up to 1 to 6).

In addition to the seawater intake, the two floors of the Città del Mare underground car park are also made with the Drytech Tank Waterproofing System, which is exposed to a 5-meter water table, as can be seen from the pressure of the jet that comes out of the pump well in the third image.
