Physical / Chemical Wastewater Treatment Systems Overall System Design
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.
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.
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.
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.
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.
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.
Our Continuous Metals Removal Process
(CMR) removes all common metals to the parts per billion level in a continuous-flow
process at flow rates up to and over 1,000 GPM. Oils, greases and other
contaminants are removed in the same step.
