Key takeaways

Ozonia belongs to science; place it in that map before memorising details.
Learn the definition first, then one example that makes the definition concrete.
Connect Ozonia to a quantity you can measure, compute or draw — that is where exam questions come from.

Reference excerpt

Ozonia is a multinational water treatment equipment manufacturer headquartered in Zürich, Switzerland. It operates under the company, Degrémont, which is a subsidiary of Suez Environnement, a French-based utility company which operates largely in the water treatment and waste management sectors. Ozonia specializes in manufacturing systems that deliver ozone, ultraviolet (UV) and advanced oxidation process (AOP) technologies in the municipal, industrial and leisure markets.

History 1990 Degrémont and Air Liquide acquired ABB's (formerly BBC's) ozone department. This was the genesis of Ozonia. 1991 The Ozonia brand was officially launched at the International Ozone Association (IOA) Congress in Monaco. As a partnership between Degrémont and Air Liquide, Ozonia offices are opened in Zürich and in Paris. Also, Ozonia's first big installation (360 kg O3/h), a pulp and paper bleaching application, was installed for Union Camp in the US. Ozonia was the first to develop a technology based on an oxygen recovery loop, enabling it to recycle 80% of the process oxygen needs. 1992 Ozonia installed the first project using new ceramic "AT dielectrics". The Contra Costa Water Treatment Plant in San Francisco (200 kg O3/h) illustrated the ability to produce higher concentration ozone while reducing oxygen consumption. 1993 Ozonia North America was founded after Ozonia AG acquired "Griffin". The new American subsidiary manufactured ozone generators compliant with the North American standards. In the same year, to expand the Ozonia product line with small ozone and UV units, Triogen, based in Glasgow, joined Ozonia and the Degrémont group. In 2019, Triogen was sold to Bio-UV. 1996 To satisfy the rapidly growing Asian market, Ozonia opened an office in Seongnam City, South Korea, after acquiring a majority stake in "CHAMP Ozone". 1997 Agreements between the Swiss and Russian governments promoted the use of ozone for water treatment throughout Russia. Ozonia Russia was created was created and opened its office in Nizhny Novgorod. 1998 As business continued to grow in Asia, Ozonia opened an office in Tokyo to cater to Japanese customers. 2000 Daegu City in South Korea (350 kg O3/h) becomes the first project in the world where ozone is used for the treatment of wastewater. The contract was celebrated at Ozonia's 10th anniversary. 2005 Degrémont bought out Air Liquide's ownership stake and became the sole shareholder of Ozonia. Ozonia expanded its presence to seven countries: Switzerland, France, United States, Great Britain, Russia, South Korea and Japan. 2005 The widespread use of ultraviolet (UV) technology became a focus for the group. Infilco Degrémont and Ozonia form a UV disinfection group to market the Infilco's Aquaray UV product line. 2006 Ozonia unveiled the MODIPAC, a technological breakthrough in ozone power supply. The MODIPAC increased power while reducing footprint and eliminating harmonics. 2008 Ozonia launched an innovative new dielectric technology: the "Intelligent Gap System (IGS)". The IGS technology drastically improved the efficiency and energy consumption. As a result, Ozonia won the International Water Association's (IWA) Project Innovation Award. 2009 To expand its operations due to the growth in the leisure market, Triogen opened a new facility in Glasgow, Scotland. 2010 Ozonia opened a new "Process Applications" department. The department showcased Ozonia's knowledge in various applications including pulp bleaching, wastewater and aquaculture, with a goal to better educate clients. Ozonia North America also opened a new facility in Leonia, New Jersey, to address the growing ozone and UV markets in North America. 2012 Ozonia opened a new production center based in Zürich, Dübendorf. The new facility increased production capacity and efficiency, and improved the quality and the ability to engineer project specific equipment. Micropollutants: The "ARA Neugut" wastewater treatment plant in Zürich-Dübendorf became the first wastewater treatment plant to treat micropollutants in Switzerland. The project represented a key step for future projects in Switzerland and around the world. 2013 Ozonia opened another new production center in Tianjin-Wuqing, China. The new center is a major milestone that allows Ozonia to design and manufactures ozone generators locally that address the Chinese market.

Activities Ozonia manufactures ozone, ultraviolet (UV) and advanced oxidation process (AOP) technologies and systems for water treatment.

Ozone It is a well-known fact that ozone, a very strong oxidant, is used in water treatment disinfection. It shows an extensive range of applications; drinking water, wastewater, water disinfection, color removal, micropollutants, pulp & paper bleaching, process water, ballast water, cooling towers, beverage and water bottling, aquaculture, aquariums (zoos), cyanide regeneration, food/ produce/ poultry, swimming pools, ultrapure water and many more. It is also used for the deodorization of waste air emitted from water plants and for the reduction of sludge from biological wastewater treatment (sewage treatment). The technique that enables the ozone generators to produce ozone at an industrial scale consists of applying a corona discharge or dielectric barrier discharge to dry gas that contains oxygen. Water treatment using ozone is environmentally friendly especially compared to the chlorination disinfection method. This is due to the fact that the residual ozone molecules detach from oxygen molecules after the oxidation process. Thanks to this characteristic of ozone, there is no hazardous by-products produced afterwards.

Worked examples

Example 1 — a first encounter with Ozonia

Start with the simplest possible case. Write down what Ozonia claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In science, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Ozonia before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Ozonia ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Ozonia

In research: Ozonia appears in science research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry: Engineering practice reuses Ozonia in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom: Ozonia is common in secondary-school and first-year university syllabi. It links to neighbouring topics Manufacturing companies established in 1990, Manufacturing companies of Switzerland, Swiss companies established in 1990, so understanding it makes those chapters shorter.
In everyday life: Look for Ozonia outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
