Generally, industrial wastewater treatment includes primary, secondary, and tertiary process that involves large amounts of energy, excessive sludge production, high operational cost, and more bad odors in the treatment of industrial wastewater.
Why is wastewater treatment important?
Industrial wastewater treatment, recycling, and reuse is an important theme in today’s context, not just to protect the environment from pollution, but also to conserve water resources so that water stress is reduced. A number of technologies are available to treat industrial wastewaters, and judicious decision making is required for selecting appropriate technologies. The selection depends on the desired goals of wastewater treatment: recovery of valuable chemicals from wastewater, possible water recycling and reuse, complying with the statuary norms for discharge into water bodies, and economics of the treatment process. The number and diverse nature of pollutants in wastewater makes the task of selection rather difficult. The overview presented here should be useful in identifying key issues and facilitating selection of appropriate processes for treating wastewater. Various technologies are discussed in detail in the chapters following.
What is the most common adsorbent in wastewater treatment?
Activated carbon is the most common adsorbent in use for industrial wastewater treatment. Other adsorbents include synthetic resins, activated alumina, silica gel, fly ash, shredded tires, molecular sieves, and sphagnum peat. Because adsorption is a surface phenomenon, a desirable characteristic of an adsorbent is a high surface-to-volume ratio. Surface-to-volume ratios are increased in two ways: by decreasing the size of particles of adsorbent and by creating a network of pores or “tunnels” within the particles of adsorbent.
What is the process of aeration?
For an industrial wastewater treatment, aeration is part of the stage known as the secondary treatment process where aeration provides oxygen to bacteria for treating and stabilizing the wastewater biodegradation process.
Is wastewater treated anaerobic or anaerobic?
A traditional treatment method requires more amount of energy for treating wastewater. In the last three decades, anaerobic treatment processes are finding growing application in the treatment of domestic water and industrial effluent.
Wastewater disposal solutions to meet industrial waste compliance and reuse standards
Industrial wastewater is a by-product from the manufacturing of commercial products. Whether it is from the food we eat, the beverages we drink, the clothes we wear or the paper and chemical products we use, water is required for nearly every step of production across a multitude of industries.
The treatment of effluent is vital before it is discharged back into the environment to prevent damage to our ecosystems and human health
Evoqua provides a complete range of solutions and services for industrial wastewater treatment to:
What are the by-products of wastewater treatment plants?
Ironically, a by-product of wastewater treatment plants is producing wastes that contain many potential contaminants. Even chlorine-disinfected reclaimed water may contain such disinfectant by-products as trihalomethanes and haloacetic acids. Solid residues of wastewater treatment plants, known as biosolids, contain common fertilizers, but also may also contain heavy metals and synthetic organic compounds found in household products.
What are the metals in wastewater?
Many of these plants discharge wastewater with significant levels of metals such as lead, mercury, cadmium and chromium, as well as arsenic, selenium, and nitrogen compounds (nitrates and nitrites).
What is metal finishing waste?
The waste produced from metal finishing operations is typically a slurry (sludge) containing metals dissolved in liquid. Metal plating, metal finishing and printed circuit board (PCB) manufacturing operations produce a lot of sludge containing metal hydroxides such as ferric hydroxides, magnesium hydroxides, nickel hydroxides, zinc hydroxides, copper hydroxides, and aluminum hydroxides. Metal finishing wastewater must be treated to comply with all applicable regulations as these waste to the environment and to people/animals.
What must be removed before the water can be safely discharged back to land?
To comply with existing laws, any organic and inorganic pollutants to water used in industrial production must be managed. Organic matter, metals, and the like found in the wastewater must be removed before the water can be safely discharged back to land, into bodies of water, or reused in plant operations.

What is the water used in the production of iron and steel?
The water used in the production of iron and steel is for cooling and by-products separation. It becomes contaminated with products like ammonia and cyanide in the initial conversion. Waste streams include benzene, naphthalene, anthracene, phenols, and cresols. The forming of iron and steel into sheet, wire or rods requires water as a base lubricant and coolant, along with hydraulic oils, tallow and particulate solids.
