Two below-ground ,acid neutralization, system (ANS) tank vaults were located at the northern and southern ends of the 901 and 902 Thompson Place buildings, respectively. The ANS tanks for both 901 and 902 Thompson Place were constructed of coated concrete and were used to contain acidic industrial ,wastewater, that was neutralized by adding caustics before discharging to the sanitary sewer.

Regardless of such ,thoughts,, one of the earliest discoveries of CoVs in ,wastewater, was performed in 2013 [49]. Such investi- gation worked on the discovery of deoxyribonucleic ,acid, (DNA) and RNA vi- ruses during a 12-month survey in the USA and CoVs were detected in waste- water in 1 of 12 samples employing microarrays.

The ,acid, etching was conducted with different modes and different topologies of acids and bases but in the end the best results are obtained with nitric ,acid,. This choice was carefully evaluated also in function of the environmental impact because of the main drawback of this technology is that, however, we must eventually neutralize a residual ,acid, polluted in part by metals.
