PROBLEM TO BE SOLVED: To provide a foaming solid flocculant which does not generate dust and rapidly foams and collapses to be dispersed when mixed in waste water. SOLUTION: The foaming solid flocculant for water treatment comprises 50-90 wt.pts. of an inorganic flocculant such as aluminum sulfate and gypsum or of an organic floculant such as a polyacryl amide and a salt of a polyacrylic acid, 50-10 wt.pts. of a foaming agent such as sodium carbonate and sodium hydrogen carbonate, and 0.1-20 wt.pts. of calcium silicate as a forming auxiliary agent (a total amount of the flocculant and the foaming agent is 100 wt.pts.).
