Formaldehyde is an organic compound with the formula CH2O. It is the simplest form of aldehyde, hence its systematic name methanal. A gas at room temperature, formaldehyde is colorless and has a characteristic pungent, irritating odor. It is an important precursor to many other chemical compounds, especially for polymers. Commercial solutions of formaldehyde in water, commonly called formalin, were formerly used as disinfectants and for preservation of biological specimens. Formaldehyde is a building block in the synthesis of many other compounds of specialised and industrial significance.

Aquapure-1000
Effervescent Disinfectant Tablets Description Aquapure are effervescent tablets used primarily for the disinfection of farm water.
These tablets are also used for disinfection of surfaces and equipment on farms.
They are soluble tablets which, when dissolved in water, give a measured dose of hypochlorous acid (measurable as free available chlorine) and thereby provide a convenient, economical and accurate method of disinfection on farms. Water treated with Aquapure will be microbially safe for consumption by all farm animals. The active constituent of Aquapure is sodium dichloroisocyanurate (sodium troclosene). On addition to water, it releases hypochlorous acid (measurable as free available chlorine), and monosodium cyanurate (a non-toxic and biodegradable compound) Composition Sodium Dichloroisocyanurate 8680 mg. Indications Aquapure Tablets are effective against a broad spectrum of Bacteria (like Actinobacillus pleuropneumonia, Aeromonas hydrophila, Bacillus anthracis, Bacillus intestalis, Bordetella bronchiseptica, Brachispira, Brucella spp.,
