Disclosed are a water treatment apparatus and a process for treating process water with ozone and ultraviolet radiation. The apparatus comprises a reactor (4) having a first (5) and a second (6) reaction chamber. The first reaction chamber (5) has a UV lamp (1), an air inlet (30) and a gas outlet (23). An air/ozone conduit (34) is connected to the gas outlet (23), via which an air/ozone mixture (b) can be fed into a water inlet conduit (31). The second reaction chamber (6) is connected to the water inlet conduit (31) and a water outlet conduit (32). The inlet conduit (31) may contain a water filter (18) as well as a controllable circulation pump (16) designed to pump water in the reactor direction. The water filter (18) may be arranged between the circulation pump (16) and the reactor (4). A recirculation conduit (33) comprises a pump (10) pumping water towards the inlet conduit (31). It has a feed point (21) at which the air/ozone mixture (b) is feedable into the process water (d) or is in fluid communication with a fresh water conduit (35) via a fresh water feed point (9), which has a feed point (21) at which the air/ozone mixture (b) is feedable into fresh water (f) in the fresh water conduit (35).

A water treatment system using ozone is disclosed. The system includes a container for holding water, an ozone supply configured to supply ozone, and a water treatment device secured at a lower portion of the container. The water treatment device is configured to disinfect the water using ozone in the container. The water treatment device includes a housing having a plurality of openings and a tortuous porous tube in the housing. The tortuous porous tube is configured to receive the ozone from the ozone supply and distribute the ozone into the water.

The efficiency of water disinfection can be significantly increased by supplying the ozone in combination with oxygen to an inlet of a cavitation pump or a line atomizer. A compressor can be introduced at an inlet of the cavitation pump or the line atomizer, compressing the gas mixture at a pressure higher than the pressure within pump or the atomizer. The compressed gases are provided to the inlet of the atomizer or the pump, where the compressed gases mix with the water and enter the cavitation pump or the line atomizer (where most of the dissolution of the gases happens). The compressor allows to increase the amount of oxygen and ozone provided to the pump or the line atomizer, increasing their dissolved concentration. In addition to the disinfecting properties, the higher level of oxygen correlates to an improved taste of the water.

A system for creating an oxidation reduction potential (ORP) in water employs a manifold. The manifold includes an enclosure containing a plurality of fluid paths and having one or more ozone intake ports. The ozone intake ports are fluidically coupled to one or more ozone output ports of an ozone supply unit housed in a separate enclosure. A plurality of flow switches are disposed within the enclosure and configured to transmit control signals to one or more controllers of the ozone supply unit in response to sensing a flow of water through the fluid paths in order to cause the ozone supply unit to generate ozone. A plurality of fluid mixers are also disposed within the enclosure. The fluid mixers are fluidically coupled to the ozone intake ports and configured to introduce the ozone generated by the ozone supply unit into the water flowing through the fluid paths.

The disclosure relates to a method of performing ozonolysis or ozone-based oxidation on a liquid or emulsified reagent using a tubular falling firm reactor with one or multiple tubes wherein the combined ozone and carrier gas flow is co-current.

A water treatment system (10) includes an ozone generator (3) combined with an electrolytic chlorine generator (4010) in a compact, efficient and serviceable assembly. The system (10) may include a modular and replaceable ozone generator (3), which allows a damaged or non-functional ozone generator (3) to be quickly and efficiently replaced. In order to protect the ozone generator (3) from damage, a fail-safe drain valve assembly may also be provided which will expel backflowing pool water before it is allowed to backflow into the ozone generator (3). The water treatment system (10) may further include an insulated electrolytic chlorine generator (4010) that mitigates or eliminates leakage current for efficient operation.

The invention discloses a double-tank oxidation pond for evaluating catalytic ozonation efficiency, comprising detachable tank bodies made of organic glass, movable ozone aeration pipes and sampling holes. Each tank body has three sections. The height of ozone aeration tube and the number of the holes can be adjusted. The holes are distributed at different positions of the tank bodies for real-time in-situ sampling. It is easy to observe the distribution profile of the gas, liquid and solid phases in the tank bodies. The square double-tank structure is similar to actual production process, and thus the experimental data is easy for computer simulation to enlarge to the actual production process. The size of the ozone aeration pipe and the position of holes in the tank can be adjusted to evaluate the catalytic ozonation effect of sewage treated by different aeration ways and aeration heights.
