The present disclosure relates to methods of treating water to remove contaminants, including harmful metal ions, and water treatment plants for practicing such methods. In an embodiment, the process includes adding a sulfur-containing, metal-decreasing agent; an iron (III)-containing, metalloid-decreasing agent; forming a solid precipitate from the contaminated water, wherein the solid precipitate includes a solid metal sulfide, a solid iron metalloid, a solid calcium metalloid, or a combination thereof; and separating the contaminated water from the solid precipitate to form purified water.

The present invention relates to a method and a use of a composition, in each case for reducing the emission of environmentally harmful climate gases methane and/or carbon dioxide from farm manures during its storage. In some examples, the method and use involves bringing a composition comprising calcium cyanamide into contact with the farm manure.
