Process for the preparation of vinyl chloride homo- and copolymers in powder form capable of yielding plastisols. A spray-drying operation is carried out on a vinyl chloride homo- or copolymer latex. The operation is carried out so that the processing temperature of the said latex to be subjected to the spray-drying operation is at least 40 DEG C and lower than the temperature of onset of deg...

Wastewater containing nitrate and/or nitrite is purified by passing said water, in a first stage, under reducing conditions through a basin or a filter containing naturally occurring filter material. The reduced water is then oxygenated in a second stage and kept in a basin until the oxidation processes are completed.
