Industrial
Wastewater includes the liquid discharges
from Industrial process such as manufacturing
(chemical, Pharmaceutical, Steel, etc) and
food processing (slaughterhouses, sugar
mills, etc). This recycling of water is
used to separate oil and water, separate
emulsified oils, and provide our customer
with a quality of water that can be reused
for their processes.
During the past decade,
environmental concerns have escalated around
the world. Governments are responding by
applying regulations and pressure on various
industries to reduce unproductive consumption
of chemicals and discharge of hazardous
Wastes.
WETICO’s Specialized
Team of Engineers works in partnership with
clients to solve most of their Environmental
Problems caused by Industry.
Numerous processes and
state-of-the-art technologies are applied
at WETICO to treat wastewaters of diverse
types of industries, such as Physical, Physiochemical,
Biological and Bio-chemical Processes.
Physical Processes
Physical Processes are
either alone or combined with other processes,
and they contribute in almost all treatment
phases (primary, secondary, and advanced
or tertiary)
WETICO caters very wide spectrum of Physical
unit operations and equipment, the following
is some of physical equipment implemented
commonly in Industrial W.W.T.P:
- Screens (Coarse, fine, and sieve, Mechanical
or manual)
- Primary clarifying units (primary separators,
Clariflocculator, Dissolved Air Flotation
(DAF) Tank)
- Surface or Submerged Aerators.
- Mechanical Sludge Dewatering Processes
WETICO utilizes different sludge concentration
mechanisms depending on the type of sludge
(whether granular or crystalline, sticky,
thixotropic, gelatinous, cohesive or fibrous),
required consistency and cost of transport.
- Cooling Towers.
- Clarifiers.
- Separation Processes
membrane separation processes are used
for such applications as: removal, recovery
or concentration of metals; sterile filtration
in the medical industry; recovery or concentration
of electrocoat paint; textile sizing;
oil; and fractionation of whey.
- Filtration units (Rapid, Slow rate,
Gravity, and Pressurized)
Chemical-Physical Processes:
Chemical-physical processes are used for
removal of many metals through hydroxide
precipitation and alkaline chlorination
removal of oils and fats, removal of suspended
solids and improving sludge consistencies.
- Chemical Dosing Systems (Polyelectrolyte,
Caustic Lime, and Coagulant Dosing Systems)
implemented in Physical Processes.
- Nutrient Dosing Systems (Phosphorus,
and Nitrogen Dosing units).
- Odor Control Systems
Biological and Biochemical Processes
These processes are mainly used for removal
of BOD, COD TKN and Organics (BTEX, MTBE,
PCB, TCE, Pesticides, Chlorinated Solvents,
Phenols, Aromatic Amines, etc).
- Conventional Activated Sludge Processes
(based on sludge recycle to the Biological
Reactors).
- Aerobic Ditches.
- Pond Processes.
