A bubble wall is a water feature that is completely enclosed. This means the water cannot be touched from outside. An enclosed features makes bubble walls easy to maintain and an excellent choice for public areas where you do not want people passing to touch the water or make a mess. Lets look at how these unique items function and what effect they produce.
Bubbling water features can be made of acrylic or glass. Acrylic is usually preferred because it resists breakage much better then glass would. The inside of the bubble panel is hollow, this is the area that is filled with water which enables the air bubbles to travel through it.
Usually the central panel is channeled, the channeling enables the bubble streams to rise in individual streams which makes the visual display calmer because the flow is less erratic. You can also make the panels with an open design with will produce a swirling motion to the bubbles.
Bubble walls need to be framed to enable it to stand on the floor and to cover the top section which will enclose the lights and prevent dust from falling in the water from above. The best frame materials are either acrylic, stainless steel or copper.
There is an air pump that needs to pump air into the water panel section which is what creates the bubbles. There is a small tube that the air is pumped into and the tube has a series of small holes in it. As the air is pumped into the tube and the air pressure is generated the air will exit through the small holes in the tube and bubble out. Air is lighter then water so the air will rise through the water in the form of millions of tiny bubbles which produces the main visual effect of the bubble wall.
