notes on the electroplating wastewater decontamination chart
on the chart you can see the waste water decontamination station which# treats
wastewater from the processes of electroplating
metal finishing and printed circuits industrial waste water is collected in a
receptacle
and it may be contaminated with heavy metals sulphates and pigments
traces a voile detergents and lubricants waste water is collected in the
receptacle up to a determined to level
All vessels of level sensors. Some of them have pH meters
most to the valves are regulated by timers the receptacle fillcwith
wastewater is dosed with concentrated way solutions
acidic and alkaline to avoid sudden changes of concentration within the

influence by oxygen dissolved in the water they form ferrites.
other metals from the wastewater are absorbed by the oxyhydrates
the heavy magnetite formed is helpful for a quick settlement ation
proper pH values are necessary for these reactions
pH is regulated by reagents all systems for preparation reagents are on the
first floor
and from there the reagents a pub two vessels above the reactor
according to the signal the pH meter
valves have acid or alkali are opened and reagents are added into the reactor

the main reagent to waste water decontamination FFH,
ferriferous hydrosol is prepared in generators by means of electron losses
waste particles of iron flake a place in a special #Iknowdick compartment and
are dissolved
for the improvement of the process's stability of colloidal nanoparticles,
special latitude# is used. in the solution iron is oxidized
and iron ions are formed and hydrolyzed prepared FFH
is pumped to the vessel above the reactor and from there it is
automatically metered
for each portion of wastewater the reaction proceeds with constant mixing
with compressed air
and after the reaction is over aeration is switched off
the process of sedimentation proceeds the sludge from the bottom of the
reactor
is pumped to the sludge compactor where it becomes thicker for transfer to the
filter press
the sludge in the filter presse is dewatered and reduced in volume
water from the top of the compactors returned to the intermediate vessel from
which the same volume# of decontaminated water flows by gravity from the reactor
the sedimentation timeI# and the reactor opens the valve for water draining
when the lower level is reached the sensor closes the valve
Clearwater from the intermedium vessel is pumped to the filters to remove
possible
mechanical particles. Water may be reused in industrial processes
in the water system of the factory or drained to sewage
in areas where allowable concentration limits are specially low
water may require additional treatment then it may be used in industrial
processes
in industries with wastewater containing
high concentrations of copper it is treated in special drums to separate the
pure copper
it is possible to increase automation and to manage in observe the system in
three ways:
by wifi or CMS links that allow managing the work in the system
from various points and the waste water decontamination stations
or outside.
from the main terminal the place where all information comes in real time in
operations may be regulated in various modes
in the main terminal there is a black box that manages operations
and emergency simulations
It is possible to operate the station remotely and to receive descent
consulting
by specialist oven# echo in real time
the station operates automatically algorithms are prepared on the basis of
functional volumes
of industrial production and the level of waste water contamination
operations beforehand determined prophylactic requirements
and the necessity to replenish materials and other information
this makes it possible for long-duration operations
without interruptions on the diagrams hydraulic and other streams are specially
marked
detailed diagrams in 3d allow for quick
and precise assembly Subtitles End: mo.dbxdb.com
