Title: Water treating coagulant aid and coagulation treatment method
Inventor: KATAOKA KATSUYUKI
IPC: C02F1/56
Filed: 1998-06-29
Abstract: PROBLEM TO BE SOLVED: To make a water treating coagulant aid safe for the human body though used for water purifying treatment, good in coagulation efficiency and effective by containing β starch capable of being made α prior to adjustment to a specific pH value, caustic soda and/or caustic potasium, and sodium silicate, and adjusting the pH at a specific value. SOLUTION: After making β starch α as aqueous solution wherein it is mixed together with caustic soda and/or caustic potassium, sodium silicate is added. That is, sodium silicate 3, caustic soda 4 and β starch 5 are added to water 2 contained in a tank 1, and by mixing by stirring at pH 12 or higher with a stirrer 6, the β starch 5 is gelatinized to a water soluble organic polymer. Thereafter, the pH is adjusted to 11 or under by adding acid, and silicate monomer is polymerized to generate macromolecular polymerized silica. Thereby, a large particle sized floc of good sedimentation property can be formed to improve a solid-liquid separation speed, and that can be safely used for drinking water treatment also.

Abstract: PURPOSE:To lessen the number of fixing means, e.g., piles, etc., or simplify the structure of the fixing means by a method in which a concaved portion is formed at the central part of a flat structure body, and a slope is formed on the peripheral side of the structural body. CONSTITUTION:A slope 5 to be in contact with by ice plate 15 is provided on the peripheral side of a structural body 2 of a flat plate form, and a concaved portion 3 is formed on the inside surrounded by the slope 5. An oil well drilling equipment, e.g., platform 4, etc., is housed in the concaved portion 3. When the ice plate 15 moves toward the body 2, the end of the ice plate 15 is warped upwards and broken by bending stress into ice pieces 15a which go over the edge 6 and are packed into the concaved portion 3. Since the weight of the platform 4 and the weight of the body 2 as well as the weight of the ice pieces 15a are applied to the structure 1, in the freezing season, the sidewise movement of the body 2 by the ice force F can thus be prevented.
