The aquarium was constructed from 41 acrylic panels – 26 panels for the outside cylinder and 15 panels for the inside cylinder for the elevator – which were bonded together on site. [7] With a diameter of about 11 m (36 ft) and a height of about 16 m (52 ft), resting on a 9 m (30 ft) tall foundation, it held the Guinness World Record for ...
A spherical airstone at the Osaka Aquarium alongside a trio of red stingray pups, Hemitrygon akajei. An airstone, also called an aquarium bubbler, is a piece of aquarium furniture, traditionally a piece of limewood or porous stone, whose purpose is to gradually diffuse air into the tank, eliminating the noise and large bubbles of conventional air filtration systems, and providing other ...
The BIQ House built in 2013 [33] [34] in Germany is a showcase experimental bionic house using glass facade panels for the cultivation of micro algae. [35] Once the panels heat up thermal energy can also be extracted through a heat exchanger in order to supply warm water to the building. [ 35 ]
With the release of large bubbles from the system, a turbulent displacement of water occurs which results in a mixing of the water. [5] In comparison to other aeration techniques, coarse bubble aeration is very inefficient in the way of transferring oxygen. This is due to the large diameter and relatively small collective surface area of its ...
Glass microspheres are usually between 1 and 1000 micrometers in diameter, although the sizes can range from 100 nanometers to 5 millimeters in diameter. Hollow glass microspheres, sometimes termed microballoons or glass bubbles, have diameters ranging from 10 to 300 micrometers.
The first modern aquarium made of glass was developed in the 19th century by Robert Warrington. [44] During the Victorian age, glass aquariums commonly had slate or steel bottoms, which allowed them to be heated underneath by an open-flame heat source. These aquariums had the glass panels attached with metal frames and sealed with putty.
