Cooling system

In industrial cooling, the applications used to extract heat from a liquid are different. To cover all the needs and possible applications of industrial cooling, Aracque offers a wide range of Cooling Towers. The need of the industrial market and the continuous search for energy saving forces us to orient our objectives towards the use of applications and technical solutions that allow us to reduce energy consumption.

Osmosis

Osmosis is a natural phenomenon by which between two solutions of different concentrations separated by a semi-permeable membrane, water tends to pass from the more diluted solution to the more concentrated one.

Reverse osmosis, on the other hand, is a scientific procedure for separating foreign bodies from water through the use of semi-permeable membranes, which allow the passage of water, but retain dissolved salts, bacteria and colloids.

The main advantages of a reverse osmosis system are essentially: low operating costs, no interruptions for regeneration, no use of caustic soda (NaOH) and hydrochloric acid (HCI) for the regeneration of the resins, it does not require purification of the waste water discharge, therefore total absence of purification plants.

The reverse osmosis process is currently the safest and most ecologically compatible water desalination technique.

Filtration

Filtration is a mechanical (or semi-mechanical) treatment with which it is possible to eliminate impurities of different nature present in suspension in water such as sand, silt, corpuscles of different nature and size, oxidized iron, etc. as well as removing bad odors, unpleasant flavors from the water and making it the desired clarity.

Sand/carbon filters and other types of filtration (ultrafiltration etc) are available for water treatment.

Purification

The operating principle adopted is based on total oxidation activated sludge biological treatment; this means that sewage is purified through biodegradation by the same bacteria present in the wastewater, making it possible to discharge clarified water with stabilized sludge.
The wastewater entering the purifier is first taken into the oxidation compartment, after an adequate residence time the sewage flows to the adjacent sedimentation compartment, where thanks to the sedimentation tank the sludge separates from the liquid part that comes out of the clarified and purified plant.

Special installations

Aracque has the possibility of supplying pre-fitted systems inside containers.
