The present disclosure provides dry compositions and methods for using the dry compositions to treat animal facilities. In particular, a dry composition comprises an acid, which provides an immediate source of protons, and a process residue comprising alum and a material comprising reactive aluminum, each of which provides a delayed source of protons.

An improved technology for inactivation of viruses, for example the SARS-CoV-2 virus that is causing the Covid-19 pandemic, is described. The technology can include a device that includes a substrate coated in a polymer that is infused with a pathogen inactivating material. In various embodiments, at a given time, a portion of the pathogen inactivating material is exposed to the environment, and the device is configured to periodically or intermittently expose additional pathogen inactivating material to the environment. For example, the polymer can be ablative or sacrificial.

A process of removing SO.sub.2 from a flue gas with a trickling filter using modified ceramsite packing is described. The biological flue gas desulfurization process includes: feeding the flue gas containing sulfur dioxide through the column bottom into the biomembrane trickling filter at certain temperature, contacting with the modified ceramsite biomembrane packing and purifying, which purified flue gas is discharged via the column top; and spraying the nutrient fluid rich in high concentration of the desulfurization strain through the top to the modified ceramsite biomembrane packing, thereby the sulfur-bearing pollution source in the flue gas is degraded, so as to discharge a purified flue gas satisfying the environmental requirements.

A filter is treated with a reduced amount of a halo active aromatic sulfanomide compound of Formula (I):

##STR00001##

wherein R.sub.1, R.sub.2, R.sub.3, R.sub.4, and R.sub.5 are independently selected from hydrogen, COOR′, CON(R″).sub.2, alkoxy, CN, NO.sub.2, SO.sub.3R″, halogen, substituted or unsubstituted phenyl, sulfonamide, halosulfonamide, and substituted or unsubstituted C.sub.1-C.sub.12 alkyl; R′ is hydrogen, an alkali metal, an alkaline earth metal, substituted C.sub.1-C.sub.12 alkyl, or unsubstituted C.sub.1-C.sub.12 alkyl; and R″ is hydrogen or substituted or unsubstituted C.sub.1-C.sub.12 alkyl, where the two R″ groups in CON(R″).sub.2 may be independently selected; X is halogen; M is an alkali or alkaline earth metal; and n is the number of water molecules per molecule of the sulfonamide compound. The compound effectively suppresses odors pre-use, in use, and post-use for extended periods of time.
