Goldfinch Evaporation Systems: A Treatment Techniques, Treatment Procedures, and Recycling Options for Industrial Waste Water Treatment

The process of industrial wastewater treatment is critical. Wastewater in this case may contain materials like chemicals or oils, and even heavy metals. In this blog, we shall examine various Industrial waste water treatment techniques, their associated procedures, and the feasibility of wastewater recycling. In this area, Goldfinch Evaporators has been a leading supplier of wastewater treatment. In this blog, we will discuss various techniques employed in the treatment of industrial wastewater and related processes as well as discussing wastewater recycling.

What does it mean to treat industrial wastewater?

Treatment of industrial wastewater means the treatment or cleaning of used water, in this case, removed from factories or industrial plants, to make it harmless for the environment or further use in production processes. However, due to the numerous types of pollutants carried in wastewater, as well as to different industries and types of contamination, treatment methods vary greatly.

Which methods are available for treating industrial wastewater?

There are various techniques for treating wastewater. Each method is designed to cope with specific types of pollutants. Below are the most common ones:

Inorganic Methods Of Industrial Wastewater Treatment

Through chemical processes, this procedure seeks to remove contaminants from wastewater. Coagulants and flocculants are the most often utilized compounds in the process, helping to remove heavy and solid metals. This method finds application mostly in industries that handle flammable materials and or toxic pollutants.

Goldfinch’s Role: Our innovative systems such as Multiple Effect Evaporators (MEE) allow for the significant reduction of the volume of chemical waste effluents for improved treatability.

Most Common Technique Used In Mechanical Filtration In Industrial Waste

This is the first step of sewage treatment plants commonly known as mechanical operations. It involves the removal of suspended solids by the use of filters or membranes. Mechanical systems assist in containing the remedial loads and volumes of contaminants within acceptable grades, thus allowing the incorporation of treatment processes like chemical or biological ones.

Goldfinch’s Role: Goldfinch’s filtration systems, implemented with MVRE combined evaporators, provide effective approaches for industries that require heavy-duty filtration with lower energy use.

How Industrial Wastewater Plants Are Working?

For those industries that are keen to adopt the green approach in their operations, knowing the effluent treatment plant process is vital. Industrial effluent treatment includes the following processes in most cases:

Primary Treatment

This stage concentrates on the elimination of bulk solids and suspended debris from the aqueous medium. It commonly incorporates screening, sedimentation, and flotation methods that assist in the separation of gross contaminations which do not require excessive removal techniques.

Secondary Treatment 

Degradation of organic compounds and lowering the biological oxygen requirement in the effluents are its primary goals. It includes biological treatment, which essentially assimilates these organic wastes through the employment of bacteria and microorganisms.

Goldfinch’s Role: During secondary treatment, for example, the deployment of our Zero Liquid Discharge (ZLD) systems allows for the recovery of clean water from wastewater, generating virtually no waste in the process.

Tertiary Treatment   

The process concludes with treating the effluent to eliminate excess nutrients and any other matter remaining in the solution. Tertiary treatment may include membrane processes such as ultrafiltration, chemical treatment, or more extensive mechanical treatment so that the water is fit for use or safe for the environment.

Goldfinch’s Role: By implementing Goldfinch’s ZLD systems, industries can work towards achieving sustainable water use through water resource recovery engineering and minimizing the discharge of toxic waste to the environment.

 What Way Is It Possible to Recycle Industrial Waste Water?

Water recycling in industries has emerged as one of the cost-cutting measures strategies as well as the quest for sustainability. In this way, the industries can treat and recycle wastewater reducing any dependence on freshwater sources and enhancing the protection of the environment.

Recycling by Evaporation

The use of Multiple Effect Evaporators (MEE) & Mechanical Vapour Recompression Evaporators (MVRE) has enhanced the recycling process. As the name suggests, evaporators serve their function by separating moisture content and impurities through the vaporization of water resulting in an easier or even more practical disposal of the unwanted trash subject.

Goldfinch’s Importance: In MEE and MVRE technologies, we enable industries to recover water from Dissolved Solid Concentrated Effuters, and therefore, support mechanical wastewater recycling practices.

ZLD Systems for Industries Handling Waste

All water recycling industries aspire to Zero Liquid Discharge. All of the contaminated water in a ZLD system is cleaned by evaporation and crystallization, which recovers water and turns the waste into a solid that can be disposed of safely.

Goldfinch’s Role: By using our ZLD systems, companies may recover all of their water without releasing any waste liquid, reducing the negative environmental effects of their operations.

Industrial Wastewater Types

What’s more, wastewater generation takes place in a variety of industries but each industry has its treatment and recycling of problems:

Wastewater from the textile industry: It is characterized by high volumes of dyes, chemicals and microfibres necessitating a mechanical – chemical approach for its treatment.

Wastewater from food and beverage industry: With high organic and fat content, this type of wastewater reclamation and disposal usually entails biological and tertiary treatment.

Wastewater form pharmaceutical industries: This kind of effluent poses a great risk with its wide variety of poisonous compounds and active pharmaceutical ingredients (APIs). Hence, the wastewater will require very sophisticated chemical and filtration systems.

Wastewater from the mining industry: consists of considerable amounts of heavy metals and hazardous toxins. And this effluent is usually treated with mechanical filtering and manipulation with some chemicals.

Why Goldfinch’s Engineering: We understand that every industry has its own constraints and therefore offer specific solutions by integrating appropriate MEE, ZLD and MVRE technologies.

Conclusion

The treatment of wastewater generated by industries is intricate and yet imperative if the aim is to ensure that the water in industrial activities can either be reused or discharged into the environment without causing pollution. In an era dominated by technology such as Multiple Effect Evaporators (MEE), Mechanical Vapour Recompression Evaporators (MVRE), and systems of Zero Liquid Discharge (ZLD), industries can manage wastewater treatment and rerouting of wastewater back to use in an environmentally conscious manner.

A Simplified Comparison MEE vs. MVRE

A Simplified Comparison: MEE vs. MVRE

MEE vs. MVRE:

Goldfinch Evaporation Systems offers two main types of evaporators: Multiple Effect Evaporators (MEE) and Mechanical Vapour Recompression Evaporators (MVRE). Both are designed to enhance efficiency in industrial processes, especially in wastewater treatment and resource recovery. Here’s a simplified comparison to help you decide which system suits your needs best.

Multiple Effect Evaporators (MEE):

How MEE Works:

  • MEE uses a series of stages (or effects) to evaporate water.
  • Vapor from each stage of MEE is used to heat the next stage.
  • MEE reduces energy consumption by reusing heat.

Benefits:

  • Energy Efficiency: High steam economy. For example, 1 kg of steam can evaporate up to 3 kg of water in a three-effect system.
  • Cost-Effective: Lower operational costs due to reduced steam usage.
  • Scalable: MEE is easily scalable by adding more effects.
  • Applications: Ideal for industries needing large-scale evaporation with lower energy costs, such as food processing, pharmaceuticals, and wastewater treatment.
