ABSTRACT:
The invention relates to a method and a means for de-silting water. The settling of silt in inland lakes and dams considerably reduce the effective life span of such lakes and dams, and also cause a substantial loss of fertility of the agricultural lands from which the silt originates. The invention provides a method for removing silt particles from water by first agglomerating the silt particles into larger size particles, imparting hydrophobic properties to the larger size particles and floating the same to the surface, and removing the floated matter. The invention also provides an apparatus for removing silt particles from water which includes means for feeding into and mixing with the water chemicals selected for agglomerating the silt particles and converting them into larger size hydrophobic particles, means for bubbling air through the water to float the larger size particles to the surface, and means for removing the floated matter.
