Semiconductor
In the semiconductor industry PACT joined TSI, a technology
partner to avail itself to the wealth of experience of TSI
principals in the field. A lifetime experience in servicing
almost all internationally recognized names in this industry
(SMIC, GSMC, HP, IBM, Motorola, AMD, Analog Devices, Philips
Semi among others). PACT TSI processes are used to treat Fluoride,
ammonia, Arsenic, Heavy metals, CMP effluent, BOD, COD, suspended
solids and pH adjustment.
Pharmaceutical
PACT’s experience with such companies as SmithKline
Beecham, Johnson and Johnson and Wyeth among other pharmaceutical
giants has been rewarding in acquiring the necessary know-how.
Treatment processes used cover biological, chemical and membrane
separation. Biological processes implemented by PACT cover
both aerobic and anaerobic. Aerobic processes were enhanced
by utilizing SBR and MSABP versions for higher efficiency
and low sludge generation. Membrane separation are utilized
successfully for treatment of wastes that are not tolerated
by biological processes (toxic content) and those wastes that
are oil-based.
Automobile
In the automobile and auto-part industry PACT’s experience
with such companies as Eaton, Eisenmann, Caterpillar emphasized
PACT’s know how in removal of metals (from the metal
plating process), emulsified oil & grease (from the grinding
process) and paint (eco paint process). Treatment technologies
covered one or more the following: ultrafiltration, biological
and chemical and physical precipitation.
Chemical and Petrochemical
Treating wastewater from polystyrene manufacturing, PTA,
hydrogen peroxide, oil refining, etc. Wastewater generated
by Chevron, Elf Atochem, Sinopec, Latexia, GE Betz and others
and treated using PACT know-how and specialty processes. Processes
such as DAF, chemical-physical, API separators and biological.
Food & Beverage
Clients such as Pepsico-Lays, Pepsico soft drinks,
Coca Cola soft drinks, General Mills, etc. are few of
PACT clients engaged in the food and beverage industry.
Typically high volume wastes and high COD/BOD and oil,
requiring either multi-stage aerobic treatment or multistage
combined anaerobic and aerobic treatment. In the Pepsico-Lays
potato manufacturing plant, the main pollutants were
high suspended solids (from potato peel), high BOD/COD
and oil. The wastewater was screened first to remove
the solids followed by oil skimming, first stage biological
using trickling filters (to save on power) followed
second stage biological using the extended aeration
process.
