OZONE WORKS SWIMMINGLY AS PURIFIER

Question - Swimming pool chemicals are expensive and irritate my eyes and skin. How effective are activated oxygen purifiers for pools and spas so I can use less chlorine? Do they cost much to operate? - H. D.

Answer - Activated oxygen, ozone, is one of the best and safest swimming pool and spa purifiers. An ozone purifier can cut chemical usage by 80 percent and eliminate burning eyes, faded and bleached bathing suits, dry skin, etc.

Many major cities use ozone to purify their drinking water. You may have been drinking and showering with ozone-purified water for years.

A very low concentration of ozone gas in water is not harmful to people or pets, but it literally destroys bacteria, viruses and tiny particles. Within several minutes, ozone converts back to pure oxygen.

Ozone gas breaks down bacteria and virus cell walls in seconds and kills them. Chlorine takes hours to slowly penetrate these cells. Chlorine can react with common compounds in the pool to create cancer-causing chemicals.

Ozone purifiers for pools or spas are simple to install yourself. Just plug it into an electrical outlet and run a small flexible tube to the filtration plumbing. Many ozone units use less electricity than a 100-watt light bulb.

Ozone gas, a natural flocculator, produces crystal clear water. Once it destroys the viruses, bacteria, and other contaminants, ozone causes the minute particles to coagulate into larger clumps. Although still tiny, these clumps can now be trapped by your filtration system.

The simplest ozone purifier design uses an ultraviolet light inside a closed tube (generator). The UV rays turn plain air into very low concentrations of ozone gas. This is how the sun creates the ozone layer around the earth. The replaceable lights last for 10,000 hours of on time.

Corona discharge pool purifiers create ozone with an electrical arc inside a small cabinet. This is how lightning naturally creates ozone. Ozone is the sweet fresh smell after a thunder storm. This design can produce higher concentrations for large or heavily used pools.

Question - I own an older house with real plaster walls. I plan to remodel one room and add new efficient windows and a skylight. What type of lath can be used under the plaster for my remodeling job? - R. T.

Answer - Older houses typically have one of three types of lath under the plaster. The most common type is wood lath. Horizontal wood strips are nailed close together over the wall stud. Perforated gypsum board lath was used too.

Metal mesh lath is probably the easiest to work with. A stiff steel mesh is nailed to the wall studs. As the plaster is spread over the mesh, it flows through and down a little. When it sets, it is locked into the mesh.
