A Crystal Clear Solution
Iron oxide residues in groundwater are becoming an increasing problem, estimated to affect about 40% of the world’s water bores, and anecdotal evidence indicates that this number is steadily increasing. Whether caused by naturally occurring bacteria or straight chemical means, these residues will eventually affect nearly everyone who sources water from groundwater aquifers.
This case study considers an air conditioning system servicing a 150,000m2 retail/industrial complex in Milan consisting of numerous offices, multiple car showrooms, mechanical workshops, training facilities and warehouses. The system, producing 6MW (COP=4), comprises nine geothermal plants (with the largest system 50,000 litre capacity), 3 wells (each approximately 40 metres deep) and 10km of pipework between 250mm & 10mm diameter.
