N. FREQUENTLY ASKED QUESTIONS
Questions Answers
Operating characteristics
What are the technical reasons for limiting use to 4 hours a day?
Because after 4 hours, the batteries are too discharged, and the
BIO-SUN terminal operation can no longer be ensured for the
following days (as it is calculated on the basis of statistics
depending on sunshine). The service life of the batteries would
also be significantly penalized.
Motor-drive pump feeding? Under what conditions, terminal tank
pressurized?
The desired information are shown in the BIO-SUN 85 column, for
the pressurized supply model:
. Supply type - 1.5 bar pressurized system
. Maximum pressure: 3 bars.
Is a timer used to program the terminal for a battery life of 3 days
with a daily use of 4 hours?
No.
What is the difference between BIO-SUN 85 and BIO-SUN 340?
The BIO-SUN 85 terminal does not have a built-in pump and is
fitted with one solar panel (for pressure feed) and one battery.
The BIO-SUN 340 terminal has a built-in pump and is fitted with
four solar panels and two batteries.
And what about the number of production hours: 4hours/day
mentioned in the catalogue. Can the unit be used for 8 hours in
one day assuming that it will then only have a battery operating
time of two days instead of three days?
No, the terminal must be used under the defined conditions.
How much sunlight time is needed to fully charge the battery?
3 days, which is why, on commissioning, the BIO-SUN should not
be used for 3 days.
After 2m3 of water treated in a day, does the UV lamp go off to
mean that the water is no longer drinkable? Or does the battery
stop working after 4 hours of operation?
It's manual, the volume meter acts as a control. There is no
automation: it's intentional.
Should the battery be used until discharged to ensure it has a
longer service life?
Absolutely not.
Can BIO-SUN units be used directly on the normal power grid
(220V)?
The battery supply is 12 V. As the principle of the BIO-SUN is
standalone operation, it cannot be connected to the normal
power grid (220V).
UV reactor
What is the service life of the UV lamp?
The UV lamp should be replaced once a year.
Water supply
Where is the outlet for evacuating the dirty water? At the rear of the terminal.
Maximum permitted turbidity about 5 NTU.
in the event of high turbidity: what is the recommended treatment
upstream? Filtering possibly with coagulation/flocculation, but this really
depends on the water qualities, and there is no absolute rule.
Filtering
How long does the zeolite filter guarantee last?
There's no guarantee on the media itself
On the filter body itself = terminal guarantee, in other words for
one year.
In what case is the activated carbon filter recommended? this serves to reduce organic matter, pesticides and heavy metals.
Is there a signalling/indication/alarm system? For example, to
confirm that the water coming out is well purified or to indicate
when the cartridges/filters need replacing.
There is no signalling/indication/alarm system on our cartridge
filters (for example, carbon filter): the filter cartridges should be
replaced every 3 months or so
Zeolite washable filter: guaranteed for 1 year, service life 5 years.
How long does it take to filter 20 gallons of water?
The water treatment is instantaneous, and the maximum flow rate
is 500 liters/hour.
How do you replace the cartridges and filters? By unscrewing them.
And what if the water entering the unit (tap or river water) has a
certain taste (bleach/other)? In this case, choose the cartridge filter option as this is what the
activated carbon is intended for.
Water quality
What if the water entering the unit is acidic, which is often the case
in the mining sector in RDC?
BIO-SUN's primary objective is to make water bacteriologically
safe. However, BIO-SUN does not address acidity issues.
