摘要： PURPOSE:To uniformize a reaction in the title reactor by connecting an inlet pipe and an outlet pipe to the reactor so that a liq. reactant flows in the main reaction vessel as a spiral flow, and arranging a light source to traverse the spiral flow. CONSTITUTION:A liq. reactant is introduced from the liq. reactant inlet pipe 6 as shown by the arrow (p), a chemical is injected from a chemical feeder 9 through a chemical injection pipe 8, hence the liq. reactant reacts with the chemical in the main reaction vessel 1, and the reaction product is discharged from a liq. reactant outlet pipe 7 as shown by the arrow (q), In this case, the liq. mixture of the liq. reactant introduced from the inlet pipe 6 and consisting of service water, etc., and the chemical proceeds as the spiral flow called the cyclonic flow as shown by the arrow (s). In this case, the spiral flow is successively cut by protecting tubes 2a-4a contg. UV lamps 2-4. As a result, a regular Karman vortex K is successively generated around the protecting tubes 2a-4a. By this method, extremely uniform mixing and uniform light irradiation are simultaneously carried out, the light irradiation is uniformized, and the reaction is uniformly promoted.

摘要： PROBLEM TO BE SOLVED: To control effectively the generation of algae at low cost by using an agent adding means attached, combinedly to a water reservoir for water stored in the water reservoir, circulating the stored water by a water circulating means and operating intermittently the water circulating means for a short time by a control means. SOLUTION: Copper sulfate of given amount is added into a pool 2 by an agent adding means 4, and then a water circulating means 3 is operated based on a set operation pattern by a control means 4. When the given operation pattern is set, stored water W is circulated for a short time by the proper circulating operation of a circulating pump 7 and then the stored water remains for a long time. Thus the copper ion concentration gradient in the stored water W becomes small by the circulation for a short time and the remaining for a long time, and copper ions are in existence uniformly around spores of algae, by which the selective ingestion of nutritive elements and copper ions by the spores is impossible and the simultaneous ingestion of both is performed to generate the cell destruction of spores of algae and control the generation and proliferation of algae.

摘要： PROBLEM TO BE SOLVED: To provide a method and apparatus by which even an extremely small amount of residual chlorine can be correctly measured without need for a complicated operation such as calibration using a calibration liquid and without a danger of an error caused by residual current or the like. SOLUTION: Two, first and second indicator electrodes 12, 13 are provided as indicator electrodes whose oxidation-reduction potential varies depending on a residual chlorine amount contained in sample water 24a when in contact with the sample water 24a. In this case, different voltage from one another is applied respectively to each of the first and second indicator electrodes 12, 13 and a circuit including a reference electrode 11, and polaro-current in each circuit is sensed, and the difference is taken thereby offsetting residual current or the like. Thus a complicated calibration operation or the like using calibration liquid is eliminated, so that correct measurement is immediately possible.

摘要： PURPOSE:To improve the filtration capacity by mixing specified amts. of a hydrogen ion concn. conditioner and an inorg. flocculant into water to be treated to form flocs on the surface of filter medium particles of the filter. CONSTITUTION:When the water in the reservoir for pool water, bath house water, etc., is purified, a multiple-port valve 7 is operated to connect a filtered water pipe 19 to a discharge pipe 20. Stop valves 8 and 9 are then opened, a circulating pump 6 is simultaneously operated to send the water to be treated mixed with a flocculant 12 and a hydrogen ion concn. conditioner 14 to a filter 21 for several seconds. In this case, flow control valves 16 and 17 are adjusted to control the flocculant concn. in the water to be treated to 5-200mg/l and the hydrogen ion concn. to 5-8pH. By this operation, fine flocs having strong colloidal suspended component flocculating force or adhesive force and shearing stress are formed on the surface of the filter medium particles 22 in the filter 21, and consequently water can be treated with high filtration precision.

摘要： PROBLEM TO BE SOLVED: To retain and remove fine colloidal particles and to effectively backward wash a filter in a short time. SOLUTION: Disks 22 each having many grooves on the front and rear surfaces are laminated, pressed and clamped with a spring-loaded lid 23 to constitute a cylinder 25 with a grid-like filtration groove secured between the contact faces of the disks, and the laminated-disk filter 21 is obtained. As to the pretreating method of the filter, liq. aluminum polychloride 12 and an alkali soln. 14 are injected from separate ports into a flow passage of the filter 21, into which a polluted water is to be introduced, to deposit aluminum hydroxide as the reaction product of both liqs. on the surface of the grid-like filtration groove of the filter, and the colloidal particle collecting effect is enhanced.

摘要： PURPOSE:To provide a hair collector which is capable of extremely efficiently capturing the fibrous foreign matter in water and preventing the degradation in performance, trouble, etc., of a water feed pump generated by suction of the large-sized foreign matter into the water feed pump, facilitates maintenance of the device and is inexpensively produced. CONSTITUTION:This fair collector 1 is freely attachably and detachably mounted with a hair collecting brush 3 between an inflow port 7 and outflow port 8 of a cylindrical housing container 2. The hair collecting brush to which plural filamentary bodies 16 radially arranged on a shaft body 15 are fixed is formed to a circular columnar shape as a whole. This shaft body 15 is formed by holding the filamentary bodies between two pieces of metal wires and twisting these metal wires to a double spiral form so that the filamentary bodies are arranged in superposition on each other with successive mispositioning in a vertical direction as well in the state of spreading radially in a horizontal direction according to the twists of the metal wires. The hair collecting brush forms a capturing part 17 where the filamentary bodies form a truncated circular cone shape near the inflow port. A band ring 11 for capturing having an L shape in section is fixed near to the bottom of the capturing part.
