Abstract
474,886. Purifying and imparting special properties to water. CHEMISCHE FABRIK PETUNIA GES., and PFEIFFER, K. March 20, 1937, No. 8298. Addition to 442,346. [Class 46] The water of open-air baths, which has been rendered slightly alkaline by the addition of the hydroxide of an alkali or alkaline earth in order to prevent the development of algae, as described in the parent Specification, may be further treated with a disinfectant in amount not exceeding the maximum permissible in the case of drinking water, for example with chlorine in quantity not exceeding 0À1 gr. per cubic metre. Undissolved magnesium hydroxide may be present in the water, being added thereto as such or as the oxide. Alternatively magnesium sulphate, chloride or carbonate may be added to the water, which is then treated with lime or other alkali in a quantity not greater than is sufficient to convert the magnesium salt into hydroxide. Or the water may be circulated through a filter or other container charged with magnesium oxide or hydroxide, The water may be circulated through a filter to remove dirt. The Figure shows an arrangement of a bath a and a filter a with valved connections so that water can be withdrawn from either the top or bottom of the shallow end of the tank through branches y, z, pipe x and valve m, and after passage through the filter returned to the deep end of the bath by a pump o through a valve l and pipe w. At intervals water may be withdrawn through the pipe wand passed through the valve k, filter a and valve n back to shallow end of the bath. A pump may be placed in the inlet instead of the outlet pipe of the filter, or there may be pumps in both inlet and outlet. The valves k ... n may be replaced by two-way valves at the T-junctions h, i. The walls and bottom of the tank may be coated with a chemically indifferent paint, for example, a chlorinated rubber lacquer.
