AGGREGATE SHORTAGE SPURS DUTCH TO DESIGN A SEA SAND DESALTER

IN RECENT YEARS, THE DUTCH HAVE BEEN TRANSFORMING LARGE TRACTS OF MARSHY LOW-LYING LAND INTO USEABLE BUILDING SITES BY TOPPING THEM WITH A THICK LAYER OF SAND. THE SAND USED TO BE OBTAINED FROM SAND PITS, INLAND WATERWAYS AND HARBOR BASINS, BUT THESE SOURCES HAVE BEEN DREDGED DOWN TO SUCH A DEPTH THAT FURTHER WORKING IS NO LONGER CONSIDERED ADVISABLE. VAST QUANTITIES OF SAND ARE STILL NEEDED, HENCE NEW SOURCES HAD TO BE FOUND. FOLLOWING EXTENSIVE STUDIES OF THE TECHNICAL AND ECONOMIC ASPECTS OF SEA SAND DESALINATION, A PLANT WAS DESIGNED WHICH CAN DESALT AND THICKEN 71,000 CU FT OF SEA SAND PER HOUR ECONOMICALLY USING AUTOMATED PROCEDURES AND ONLY ONE OPERATOR AT THE CONTROLS. THE CONSTRUCTION OF THE DESALINATION PLANT AND ITS OPERATION ARE DESCRIBED. /AUTHOR/
