Simulation and Modeling
de Servicios Sanitarios (SISS), Chile- Aguas Andinas:
Daniel A. Nolasco, M.Eng., M.Sc., P.Eng., President
of NOLASCO & Assoc. Inc., was
selected by Superintendencia de Servicios Sanitarios
(SISS), Chile’s Water Regulator, as the International
Expert for the tariff negotiation process for Aguas
Andinas (2005-2010 period). NOLASCO &
Assoc. Inc., together with the consulting
group Aguas y Riles S.A, supported SISS in this
successful negotiation process.
carry out the negotiation process it was necessary
to model three large wastewater treatment plants
within the operational jurisdiction of Aguas Andinas:
La Farfana WWTP (8.8 m3/s), El Trebal WWTP (4.4
m3/s) and Los Nogales (operational by 2009, 6.6
m3/s). NOLASCO & Assoc. Inc.
configured and calibrated a dynamic mathematical
model using BioWinTM. A detailed calibration process
was necessary to determine process sizing to treat
the pollutant loadings described by Chile’s
regulations and estimate capital investment and
related operation & maintenance costs. These
figures were then used to calculate and negotiate
tariffs for the 5-year period. Chemicals, manpower,
and electrical requirements were also calculated
with the use of the calibrated model.
Rovers Associates (Canada):
NOLASCO & Assoc. Inc. was retained
by Conestoga Rovers Associates, a Canadian consulting
group, to select and design the aeration system
retrofit to fine pore diffusers at the Ingersoll
WWTP in Ontario. NOLASCO & Assoc. Inc.
configured and calibrated a dynamic model to the
existing plant. The model was used to predict loadings
and oxygen requirements under various operating
conditions. Model results were used by NOLASCO
& Assoc. Inc. to design the new fine
pore aeration system, following the United States
Environmental Protection Agency (EPA) design guidelines.
|Beca Pty Ltd. (Australia):
“Design of an aeration system for
a wastewater treatment plant treating winery effluent
from Wolf Blass Winery”.
NOLASCO & Assoc. Inc. was contracted
by Beca Pty. Ltd., an Australian consulting group,
to develop and calibrate a dynamic model of this
winery’s activated sludge treatment plant,
located in Southern Australia. BioWinTM was the
software used to simulate seasonal loading conditions
to this plant, aeration demand and other treatment
requirements to optimize the performance of this
facility to meet future effluent requirements.
evaluation of Wastewater Treatment Alternatives
for Existing Facilities”.
NOLASCO & Assoc. Inc. evaluated
the existing treatment system capacity for this
alcoholic beverage company in Argentina. Selection
of future treatment processes for upgrading the
facility (trickling filter / activated sludge) was
carried out with the assistance of a dynamic model.
