1. Ultraviolet purification
It has long been known In addition, thanks to the reflection produced by the
that ultraviolet lamps at stainless steel (316 L) within the chamber, efficiency
a wavelength of 254 is increased by 20 to 30% (« Westinghouse
nanometers, or 2537 Technical Manual 1987 »).

and algicidal radiation for a minimum of 1 second. However, BIO-

eradicates germs by optimal disinfecting.
the cell metabolisms In order not to hinder the action of the UV-C it is
leading to their important to have a high filtration quality so that
destruction. large particles do not screen the radiation.
The filtration times recommended by the
professionals must be adhered to. This means that
These lamps should not be mistaken for ozone the water may flow through the chambers several
producing lamps which operate at different times per 24 hour period (for example, water at 26°
wavelengths. requires a filtration time of at least 13 hours).
Ultraviolet radiation is measured in micro
watts/second/cm². The key elements for efficient
disinfecting are based, on one hand on the
exposure time (i.e. the ratio between the size
of the pool and the flow rate through the filter
pump), and on the other hand, on the energy
emitted in micro watts/second/cm² at the
furthest point from the lamp.
Performance is measured in milijoules (mj) by
combining the energy emitted by the lamp and
the exposure time.
The BIO-UV range UV-C lamps work at levels
above the minimum required to destroy the
principle micro-organisms which may be found
in swimming pools or spas.
BIO-UV sterilisers perform at levels which are
equal to or superior to standards required for
drinking water (25 mj) at the recommended flow

3. Remanent procedure :
The ultraviolet purification process takes place inside the chamber as the water passes across the
Meanwhile the water in the swimming pool is contaminated by swimmers and other exterior elements,
which bring additional micro-organisms into water.
The complete procedure, thanks to the association of the BIO-UV ultraviolet light system and the
REMANENT will completely sanitize the water.
In order to simplify this process BIO-UV has designed an injection pump that automatically injects on a
daily basis a very small amount of REMANENT.

5. Chlorine and related products :
Chlorine : fundamentally with chlorine precise PH regulations is necessary and there are unwanted
Bromine : same chemical family as chlorine.
Salt generator : makes chlorine from sodium chloride, very corrosive.
Copper/silver ionisation : you need perfect control of the system, not good for liners pools, requires
Ozonation : requires chlorine or bromine residual.

Basic procedures :
Realizing the function of a swimming pool and its environment it is essential to
follow basic fundamental rules of hydraulic patterns, filtration, and water
balancing. This is important with any alternate sanitation system in order to
meet your expectations, reduce chemical cost, and have healthy water.
Prevention = happiness and savings
Hydraulic system :
There must be adequate water circulation in the swimming pool. The water of the pool must be
maintained for the proper amount of water flow as to reduce dead areas in the pool.
The pump and filter must be adequate for the volume of water of the pool in
order to treat all of the water in a reasonable time (4-5 hours).
Bad hydraulics = development of bacteria an algae
Filtration is essential in water treatment. Its purpose is to retain substances suspended in the water
and different particles in the filtering mass.
An oversized filter will help you save money and you will be able to space out backwashes.
A filter has to be maintained :
It is important to back wash the filter when there is a 10 lbs. differential in the
Filtration time has to be respected :
Basic rules :
½ of the water temperature
If above 27’ C add 2 or 3 hours.
Above 30 ‘ C 24 hours per day.
BIO-UV ultraviolet light system does not require floculation except in extreme cases.
Warning : never use a floculant with a D. E. Filter.
Water balance parameters :
PH indicates the acidity or alkalinity of the water. It is generally ideal to maintain a PH at 7.4 (neutral
If under 7 : acid water, aggressive to the skin and pool walls.
If above 7.8 : uncomfortable swimming conditions (itchy eyes), favors algae growth and calcium
For some type of construction, a slightly higher PH is needed, in that case a calcium sequestrian
agent should be used at the beginning of the season.

TH : This is water hardness, the calcium and magnesium content of the water. If the water
temperature is higher than 30’ F. It might be necessary to add a calcium sequestrian agent once per
A water to hard might add calcium deposits and damage plumbing.
A water to soft (acid) is more corrosive.
Elements present in swimming pool water :
Algae : these micro-organisms are mainly transported by air and develop in the pool. To fight them
you would prefer a sanitising product that contained an algaecide, for that reason BIO-UV
REMANENT contains an algaecide.
Organics : swimmers, nature and the environment mainly bring these into the swimming pool.
Organics will be retained by the filtration system and other water treatment procedures.
Micro-organisms : bacteria, virus and fungus are introduced into the water by almost every way
possible. These micro-organisms can be detrimental to your health. The purpose of the BIO-UV
ultraviolet chamber is to destroy these micro-organisms.
The injection of REMANENT avoids the development of these micro-organisms with a 2 seconds
exposure time within the ultraviolet chamber.
Avoid well water
Applications of the system :
For more details on installing the system and technical aspects of installation, see the installation guide for BIO-
The BIO-UV ultraviolet chamber has to be installed after the filter and before the heater. It is
recommended to have the water enter the vessel at the bottom and exit at the top.
While performing any work on any of BIO-UV’s products, switch off the product and unplug it from the
The BIO-UV products have to be wired in conjunction with the filtering system so both work at the
All BIO-UV products have to plug into a 220 volts circuit and protected by a ground fault interrupter
The BIO-UV injection pump has to be installed on the return line after the ultraviolet chamber and
heater. It has to be plugged into a 220 volt circuit with the brown wire in the filter box (to avoid injection
while the filter isn’t working). Periodically check the clock on the injection pump to be sure it is at the
same time as the filter clock.
In case of using no automatic PH regulation, check the PH every week and adjust it.
We recommend the use of an automatic pool cleaner to take care of dead zones in the pool.
If using a rolling pool cover, do not use it for several days, most of all if the temperature is high.
When starting the BIO-UV system, carefully, clean the pool and shock it with
hydrogen peroxide : BIO-UV CHOC at a rate of 1 litter / 10 m3, you will start the
pool under ideal conditions. Shock also at the beginning and end of each pool
