General information
Transportable water purifier unit type
SETA2E3000, 3m³/hour.
Included in ERU, Water and Sanitation,
Specialised Wat-San (e.g. Spanish Red Cross)
Objective of the plant
The unit is designed to give 3000 litres/hour of physical and
bacteriologically drinking water, the entrance water will be free of
contamination of industrial type (hydrocarbons, chemical waste, etc), according
to classification A2-A3 of the WHO. and with a turbidity for good operation not
superior to 20 N.T.U.
The destination is the one of supplying of capable
drinking water for human consumption to rural nucleus isolated in emergency
situation and with capacity of being transported by 4x4 vehicles and trailer,
including a autonomous generator plan.
Foreseen treatment
The gross water is sucked from the taking point (lake, river
eddy, canal, etc) by means of submersible pump together to flexible hose to the
tow.
Aluminium sulfate is injected at the intake of the gross water, with
crushed hypochlorite that carries out a double function; first to facilitate
solids sedimentation in the bottom of the settler and second to guarantee the
destruction of the present germs.
A basket filter of 2 mm then retains the
solids that pass through the filter of the submersible pump.
The contact
settler-chamber allows for its volume, to have a time of residence or contact of
one hour, favouring the clarification of the gross water as well as its first
disinfection. Being sedimented in the bottom, the solids are removed
periodically. Clarified water passes to the last chamber where it gets sucked by
a pumping set.
The water passes then to a SILEX FILTER to eliminate the
residual solids. Finally to ACTIVE COAL FILTER whose function is to eliminate
the odours and present flavours in the water as well as the residual chlorine
not consumed in the oxidation of the organic matter carried out in the
chlorination.
The treated water is send to 10.000L tank, getting a last
hypochlorite injection that allows the storage without bacterial, but enough
proliferation to be fit for human
consumption.
