“BSL-MED-1” unit (EKSVO)
This is a complex unit where water purication is carried out by an electrochemical
method at the molecular level, which allows to obtain biologically active water
with unique characteristics and balanced in mineral composition. It removes
harmful substances, as well as bacteria, viruses and protozoa while all
the necessary substances that are benecial to the human body (potassium,
magnesium, sodium, calcium, chloride, phosphate, carbonate, etc.) remain in
the puried water. The resulting water has antioxidant properties, stimulates the
removal of free radicals from the body. Unlike conventional lters using sorption,
- and ion exchange membrane technology, water treatment by electrochemical
method has several advantages:
• Robust disinfection. Emitted ozone and atomic oxygen kill all bacteria,
viruses and protozoa in the treated water under the inuence of the electric
eld.
• Improvement of consumer properties such as smell, transparency, color
and taste of drinking water and food prepared on its basis.
• Preservation of mineral composition. Substances which are necessary
and benecial to the human body (such as potassium, magnesium, sodium,
calcium, chlorides, phosphates, carbonates, etc. - specic for the location
you live in ) are not removed but remain in the puried drinking water
unchanged and are actively involved in the metabolism processes.
• Retention of a permanent quality of drinking water purication during
the entire period of the unit operation.
• Heavy metal salts, organic and mineral impurities are removed from
the treated drinking water; compared to conventional lters and sorption
technologies, they are not accumulated but are regularly removed.
• The quality of treated and puried drinking water stays constantly high.

3. PRINCIPLES OF OPERATION.
Several dierent ways of active inuence on the treated water are used in the
unit:
• static magnetic eld of weak intensity exposure;
• method of electrochemical coagulation;
• electrootation method;
• ltration method.
METHOD OF MAGNETIC WATER TREATMENT is performed by pouring treated
water through a ring-type permanent magnet embedded into a cap-funnel.
METHOD OF ELECTROCHEMICAL COAGULATION - all harmful substances,
including organic compounds, are actively bound and transformed by aluminum
hydroxide ions into a light foam. The ions are formed during the treatment
process in the reactor.
ELECTROFLOTATION METHOD - atomic oxygen and hydrogen are produced
during the process of turbulent water electrolysis in the reactor, then they gather
in bubbles, and actively bind the already formed foam. This foam (sludge) oats
to the surface of the treated water. It is collected in the end of the process of
electrootocoagulation with a special sludge collection cone. The sludge is
poured out and the sludge collection cone is rinsed out with tap water.
FILTRATION METHOD - treated water is poured from the reactor via the ltering
tank to the collecting tank. The ltering tank contains a ne ltering element for
residual sludge removal.
Water in the collecting tank is ready for consumption. The collecting capacity can
be of any kind (bucket, jar, can, etc.), but it is better to be a glassy one.

4. ORDER OF OPERATIONS.
4.1. PREPARATION FOR OPERATION.
• Remove the ltering element (2) from the ltering tank (1) (Fig. 2). To do so,
loosen the nut-lock (3) in the bottom of the ltering tank;
• Take o ltering element cap(1) (Fig. 3), remove lter-collectors (big 2 and
small 3) and place them in a hot solution of 3% acetic acid or citric acid for
10-15 minutes.
• Wipe the inside of the ltering tank (1) (Fig. 2), cap-funnel (1) (Fig. 6), the
reactor tank and the sludge collection cone (Fig. 5), tank for puried water (4)
(Fig. 8) with the same solution.
• Squeeze lter-collectors (2, 3) 8-10 times under running water, then straighten
them and put into the cap of the ltering element consistently, big and small
(Fig. 3).
NOTE: If the ltering element is not used for 2 weeks or more, it is necessary to
perform that procedure again.
• Install the ltering element cap (1) with lter-collectors (2, 3) in place (Fig. 3)
by snapping it into the basis of the ltering element (4).

4.2. SEQUENCE OF ACTIONS.
• Take o the cap-funnel (1) (Fig. 6) and remove the sludge collection cone (1)
from the reactor (2) (Fig. 7).
• Flip the cap-funnel and install it onto the reactor (Fig. 6)
• Fill the reactor with tap water through the cap-funnel up to the water level
mark in the form of stripes on the inner wall of the reactor (Fig. 6)
Attention: do not allow water to the control and power unit!
• Remove the cap-funnel from the reactor. Make sure that the water level
reaches the mark on the inner wall of the reactor. If necessary, add some water
or remove.
• Connect the control and power unit cord to the connector on the case of the
reactor, making sure the contact is strong and then insert the plug into the
network ~ 110-220V
Attention: it is necessary to follow the recommended sequence of actions!
• The light indicator (LED) on the control and power unit turns on with red
light and after ~ 2 seconds is ashing green with slow blinking. Bubbling and
intensive formation of foam (sludge) on the top of water (Fig. 6) starts inside
the reactor.

USER MANUAL
16 © ZAO“REKA” (REKA, JSC), 2012
• When the frequency of LED blinking changes from low to high, the water
treatment regime switches from the active process (electrolysis) lasting about
8 minutes to the passive (otation mode) lasting approximately 10 minutes.
When the ashing green LED turns o, the treatment process is completed.
Disconnect the control and power unit from the network and then from the
reactor.
• Take sludge collection cone 1 (Fig. 7) by the handle and put it into the
reactor by matching its slots with guide lugs. Load the sludge collection cone
vertically into the reactor by pressing on the handle gently, so that the cone is
lled with uid (sludge) for about 3/4 of volume.
• Remove the sludge collection cone with the liquid (sludge) strictly vertically from
the reactor (do not spill the sludge).
• Pour the liquid from the sludge collection cone and rinse it on both sides.

• Pour the treated water from the reactor to the ltering tank. The tank should be pre-
installed on cap 3 (Fig. 8), which closes the tank for puried water 4 (Fig. 8).
• The ltered water is ready for consumption.
• Merge the water remaining after ltering from the ltering tank.
• Rinse the reactor. The unit is ready for the next use.

5. MAINTENANCE
5.1. REGENERATION.
• Depending on the contamination level of the treated water, the lter-collector
elements need to be washed from 2 to 5 times a month in a hot 3% solution of
acetic or citric acid.
• If the unit is used regularly, rinsing should be done under running water, after wich
lter-collectors should be squeezed 8-10 times.
ATTENTION: in case of preservation (non-use) of the unit for over 2 weeks, lter-
collector elements must be stored in a weak solution of vinegar or lemon water.
5.2. CLEANING AND CHANGE OF ELECTRODES.
Regular cleaning of the aluminum plate of the central electrode (anode) (Fig. 4) should
be performed at least once a month. That necessity is caused by the deterioration of the
intensity of the electrolysis process because of the central electrode fouling by a layer of
sludge. For cleaning of the central electrode it is necessary to:
• Turn the reactor tank, remove the stand (6) from the reactor stand (5) by removing
the screw-lock (7) (Fig. 6).
• Unscrew the wing-nut (3) from the central electrode leg and remove the contact
lug (2) (Fig. 4).
• Carefully remove the central electrode out of the electrode set (leave the rubber
sealing gasket on the leg of electrode contact).
• Sand the plate of the central electrode (using abrasive paper, knife, etc.).
ATTENTION: It is strictly forbidden to take out the whole set of electrodes for
cleaning and replacement of the central electrode.
NOTE: if the central electrode got thin and has lost mechanical strength, it should be
replaced by a new one.
• Put the central electrode following guide lugs into the set of electrodes in initial
position.
• Turn the reactor, mount the contact lug to central electrode and apply the wing-
nut to lock.
• Check leak tightness of the reactor by lling it with water.
• Leaks are not allowed.
NOTE: The coagulant, which may occasionally appear in the treated water (depending
on the region where the unit is used), is harmless to human health
!

7. REMINDER.
1. If you wish for any reason to repeat the cycle of water purication, it is necessary to:
• turn o the control and power unit after green light “ashes” with greater
frequency and in 10-15 seconds reconnect the unit to the network;
• perform 2 full consecutive cycles of water purication.
It is undesirable to clean water for more than two times, as this will remove useful
mineral salts from the water.
2. When using a water treatment unit for the rst time, the rst portion of the
treated water from the reactor should be poured into the sink.
3. Water processed in the reactor is extremely rich in atomic oxygen and is very
active. Storing it in a glass container stimulates additional water saturation with
silicon ions, which are so necessary to the human body. When boiling the treated
water, white foam may form on its surface - that is the oxygen component. You
should not be confused by that.
4. To prevent damage of the bottom of the ltering tank (Fig. 2) when xing the
ltering element (collector) in it, screw the wing-nut with no eort, until the full
t of the ltering element (collector) to the tank bottom.
5. If the treated water contains very little natural salt (is soft), it is necessary to add
to the reactor a pinch of kitchen salt before processing.
6. Snow and distilled water cannot be cleaned in the unit, due to their zero
conductivity.
7. Sludge formed in the process of water purication is an excellent fertilizer
stimulant for any plant.
