ATMP or aminotris(methylenephosphonic acid) is a phosphonic acid with chemical formula N(CH2PO3H2)3. It has chelating properties. ATMP has better antiscale performance than that of polyphosphate through its excellent chelating ability, low threshold inhibition and lattice distortion process. It can prevent scale formation in water systems. ATMP is the phosphonate analog of nitrilotriacetic acid.In the USA, UAE, Iran Iraq, Kuwait, Saudi Arabia and other oil producing areas, several hundred chemical compounds are used in hydraulic fracturing also called fracking, fracing or frac. In some areas like UK only ‘Non-Hazardous’ chemicals are permitted for fracturing fluids by the Environment Agency. All chemicals have to be declared publicly and increasingly, food additive based chemicals are available to allow fracking to take place safely.
