An ozone supplying apparatus comprising an ozone generator for generating ozonized oxygen from raw material oxygen, an adsorption/desorption device for adsorbing and storing ozone from ozonized oxygen and desorbing the ozone, and an ozone desorbing means for desorbing the adsorbed and stored ozone for supply, the apparatus being arranged to return oxygen to the ozone generator after desorbing ozone therefrom by the adsorption/desorption device, and to desorb and supply ozone from the adsorption/desorption device, wherein the adsorption/desorption device includes a plurality ozone storing portions filled with an adsorbent, and a liquid storing portion for filling a temperature medium to an outer peripheral surface of the ozone storing portion.

Ozone supplying apparatus

An ozone producing apparatus includes an ozone generator for generating ozonized oxygen, an adsorption/desorption tower for adsorbing and storing ozone from the ozonized oxygen, and an ozone desorbing device for desorbing adsorbed and stored ozone for supply, wherein the apparatus further includes an oxygen gas supply tank for supplying oxygen to the adsorption/desorption tower at the time that desorption is started and an oxygen gas flow rate adjusting valve for adjusting flow rate of the oxygen gas to, be supplied. Ozone injection can be made definite, and the apparatus is economical in the aspect of both initial and running costs. It presents great effects of preventing slime adhesion and can also limit generation of oxidants even when applied to sea water.

An ozone producing apparatus comprising an ozone generator for generating ozonized oxygen, an adsorption/desorption tower for adsorbing and storing ozone from the ozonized oxygen generated by the ozone generator, and an ozone desorbing means for desorbing the adsorbed and stored ozone for supply, wherein a reducer storage for storing reducer therein is connected to the adsorption/desorption tower through a switch valve which is opened when the ozone producing apparatus is under an abnormal driving condition. Desorbed ozone can be safely treated even in the case of power failure or an abnormal driving condition in which high pressure or high temperature exists in the adsorption/desorption tower.

Ozone producing apparatus responsive to an abnormal driving condition

There is provided a highly efficient and compact ozone generating apparatus in which a very short air gap of about 0.2 mm is formed at high accuracy. Non-discharge portions are dispersed and disposed to cover an entire discharge space, or a spacer is provided to form the non-discharge portion. Further, an elastic body is mounted on a back face of an electrode, thereby enhancing an air gap accuracy of the discharge space.

Ozone generating method

A method for preventing biofouling in a cooling water system wherein ozone of high density is intermittently injected into a circulating line of a cooling water system in which cooling water is made to circulate in a closed system which includes a cooling tower and a heat exchanger. There is further disclosed an apparatus for preventing biofouling in a cooling water system, comprising an ozone generator for producing ozone, an ozone reservoir for temporarily storing the produced ozone, and an ozone injector for injecting the stored ozone into a circulating line of a cooling water system. Biofouling can be economically and reliably prevented.

Ozone generating apparatus

A breeding apparatus comprising a breeding water tank, an ozonizing device, an activated carbon device and a breeding water circulating device wherein breeding water of sea water or a mixture of sea water and plain water is circulated in series in these devices, and the ozonizing device is located at the upstream side of the activated carbon device with respect to the flow of the breeding water.

Breeding apparatus

An automatic observation system for observing objects such as microorganisms contained in a liquid supplied from a container. A sample of the water is fixed between two glass plates, one of which is movable relative to the other by a plunger. A condensor lens is also carried by the plunger. Light from a continuous-output illuminating source is applied through the condensor lens via an optical fiber.
