 IWWS
engineers its waste treatment systems to meet the specific
requirements of each industry and customer. Following, are
common components of an IWWS waste treatment system.
Your
Processes
The first component of an IWWS system is your plant
process. Your operations, processes conducted, sources of
wastewater, space
|
|
constraints, utilities availability, discharge points and
water reuse needs dictate our system design. We learn this
information through on-site visits, lab testing and on-site
full-scale pilot studies.
|
 |
Course Screening
Lint, scale, sand and other large objects
are removed from the waste stream via cascade screens, vibrating
screens or other course screening devices. We try to use your
existing equipment whenever possible. |
Surge Buffer
IWWS requires only a small surge buffer upstream of the Phys/Chem
system. We do not require large EQ tanks. When possible we will
use existing collection pits or tanks for this purpose. |
Physical/Chemical Treatment
pH Adjustment
Accurate pH control is vital to any waste treatment system.
Where others rely on large EQ tanks, large volumes of chemicals,
and residency time, IWWS uses a proprietary method of precise
pH adjustment. Our method ensures a constant pH that permits
the chemistry to work correctly. |
 |
Chemical and Air Injection
Depending on the nature of each waste stream coagulants , flocculants
and other chemicals such as metal scavengers (see patented Continuous
Metals Removal system) are introduced into the multi-point
injection floculator in combination with micro-bubbles. The
bubbles are produced by dissolving air or other gasses into
clean effluent. |
 |
Flotation of Waste
The IWWS method of mixing chemistry, bubbles and wastewater
produces large buoyant particles (floc) that rise quickly to
the top of the separation tank The waste particles form a "float"
on top of the tank. Skimmer paddles move the float off into
the attached sludge holding tank. The clean effluent flows into
an integral holding tank. |
 |
Sludge Handling
The sludge produced is minimal in an IWWS system. It may either
be disposed of directly or further dewatered in a small filter
press. |
|
|
Discharge or Reuse
The clean effluent is ready for discharge to POTW or reuse
in the plant, depending on your requirements.
