IMPORTANCE OF OZONE
In a series of studies published in a Journal Priroda (1976) the
Russian Department of Health established a number of important facts
concerning the use of ozone in closed indoor environments.
They established that air loses its basic "freshness"
quality merely by being drawn into air conditioning and heating
systems with as much as 90% reduction of the ozone and ion levels.
They established that the effect of the loss of these elements could
cause the occupants to complain of headaches, weakness, and a general
poor feeling and sick building syndrome. As a part of the study,
they found that after five months of testing with both a test group
and a control group that a feeling of well being returned to those
exposed to a level of 15 ppb of ozone, and that at these same levels
they were able to observe increased immune potential, higher oxygen
content in the blood, improved blood pressure reading, and the reduction
of many of the stress characteristics associated with working in
modern office environments.
They found that by reactivating the air, by the injection of ozone
to raise the level to a mere 15 ppb, the overall effect was similar
to that of taking an outdoor walk of 2 hours during the day. In
studies by the Institute of Child and Adolescent Hygiene, it was
concluded that injection of ozone into the air of schools raising
the level to 15 ppb had very positive effects on the students. In
these tests, 69% of the students exposed to these levels of ozone
decreased the time required to complete tasks requiring high levels
of concentration. In addition, it was found that favorable changes
in the functions of external respiration, increases in mental reserve
capacities, and overall increases in general state of health and
mental efficiency were observed.
WATERKING for pondsModel WK1PP
Blanket Weed Controller With External Transformer
The original, and still the world's best known Electronic Blanket
weed Controller! We do not claim to remove blanket weed completely,
but Water-King can control its growth so that it no longer causes
a problem.
LOCATION
The unit can be fitted on pipes up to
50mm in diameter and should be installed as close as possible to
the pipe. The unit will operate on any normal type of pipe material,
including corrugated, plastic and BSP (waste pipe). The pipe to
be treated must be full of water at all times which means that water
must be flowing either under pressure or suction. A pump will cause
electro-magnetic interference with the signals generated by the
Water-King and installation immediately prior to a pump should be
avoided. The optimum location is after the pump. The Water-King
will also extend the life of the quartz sleeve in the U.V. system
by keeping it free of scale deposits in hard water areas.
A period of 7 to 8 weeks should be allowed from installation before
the full effects of the Water-King may be seen.
HOW THE UNIT WORKS
Once the unit has been installed correctly on the pond system it
will pass an electronic signal which will interfere with the calcium
ions in the water. Blanket weed is a long filamentous structure
and calcium plays an important role in the strength and structure
of the membrane which is responsible for controlling the nutrient
intake to the cell. The electronic signal will disrupt the equilibrium
between the calcium present in the solution and the calcium in the
cell membrane upsetting the cell metabolism. The membrane will have
no means of preventing excess solution from entering or exiting
the cell, and this means that the cell will either expand and explode,
or shrink and die.
Initially the process will encourage growth and the weed will expand,
but once the water reaches a "super" conditioned state,
the weed will begin to die away. The Water-King will control the
growth of the blanket weed although it may not remove it completely.
DO I NEED TO DO ANYTHING ELSE
It is important that you monitor the conditions
of your pond water during this time as high nitrate levels and pH
fluctuations will cause the blanket weed to continue to grow. This
is especially important if your pond is constructed of concrete
as lime may leach into the pond water and cause a variation in the
pH level. We recommend that the nitrate level should be kept at
around 25ppm or lower. It may be higher than this, depending upon
the quality of the mains water and the filtration system installed
on the pond. If you are in any doubt then contact us or seek advice
from your local stockist.
We recommend that any dead or dying blanket weed is removed in order
to prevent de-oxygenation and clogging of filters. Regular ammonia,
nitrite andnitrate tests should be carried out during this period.
Ponds with excess amounts of decaying material can suffer from a
disruption of the Nitrogen Cycle, so a water change may be required.
It is also advisable to keep feeding down to a minimum. Uneaten
food, as well as dead weed left in the pond will encourage the return
of blanket weed. Blanket weed on a waterfall will take longer to
be effected by the Water-King because of high light levels and oxygen.
In some situations blanket weed growth can increase within the first
two to three weeks of operation. This excess growth will cease when
the unit has "super" conditioned all of the pond water.
Technical Data
The WK1PP is tested to IP68 3 meters immersion
depth and is therefore fully water proof. The aerials and power
supply are directly wired and cannot beremoved from the unit whose
circuit board is encapsulated in epoxy resin. It will not be affected
by immersion, external weather or adverse damp conditions. The Water-King
requires a 120 volt power outlet for the transformer. The transformer
is rated for indoor use only and must not be allowed to get wet
or damp, so it may be necessary to extend the low voltage power
cable to an acceptable protected socket. Additional cable may be
spliced into the existing lead between the transformer plug and
its socket. A waterproof seal should be made over the connections.
Avoid short circuiting the wires as this can cause the transformer
to fail. Satisfactory tests have been conducted on a cable extension
of 500 meters. As the low voltage supply is AC, there is no need
to be concerned about polarity.
MAINTENANCE AND TROUBLE SHOOTING
The Water-King needs no maintenance or
servicing but do check occasionallyto see that the light is flashing
