Operations - Process
Description:
Your System operator will push
a 'fill' button on the control panel activating
an on-board transfer pump. Effluent will be drawn
from the Wastewater Holding Tank into the Mixing
Chamber of the ABS unit. Filling will continue
until the 'full' level is reached. This 'auto-fill'
feature will eliminate the need for attendant
personnel to monitor the filling process for fear
of an overflow occurrence. Once the Mix Chamber
is filled, your operator will start the mixer
and add flocculation material to the mixing tank.
After 2-4 minutes, the flocculation reaction will
be completed, e.g. extraction of oil, ink, dissolved
metals and solids will be separated from the water
and a floc will be formed. Then, the operator
will open the drain/filter valves allowing the
automated separation of liquid/solid. This separation
is accommodated via the Discharge Tank that resides
directly beneath the Mix Chamber. As solids flow,
they will be captured by the filter paper media
on top of the conveyor. Semi-automatic units are
the same other than the operator must pour the
floccin material into the unit by hand (see illustration).
As solids accumulate, the conveyor
advances the filter paper forward. Eventually,
the solids will be conveyed to the sludge holder
that will reside at the end of the filter bed.
Clean water will pass through the filter media
and into the clarified Discharge Tank sump. An
on-board float-activated sump pump will automatically
discharge the treated water to sewer or to optional
collection/re-cycle vessel. The process to treat
a full batch takes less than 30 minutes, thus
an ABS-200 for example, can treat 400 gallons
per hour. |
