Industrial sludge treatment uses appropriate technologies to reduce harmful substances in industrial sludge before being discharged into the environment. This is an important and necessary process in the wastewater treatment system at production, farming, and livestock production facilities because it dramatically affects the environment and human health. So what are the properties of this industrial sludge? What are the types of sludge? Are they all toxic and treated in the same solution? Let’s find specific answers in the following article content.

The importance of industrial sludge treatment and sludge classification

To better understand the current methods and processes of industrial sludge treatment, we first need to understand an overview of the primary issues related to industrial sludge. Each industrial process will produce sludge of different nature and toxicity. The content of this article will describe in detail the types of sludge, the generation sources, and the treatment followed to the basis for requirements to develop sludge collection and treatment plans for the systems.

Industrial sludge treatment definition and source of industrial sludge

Industrial sludge treatment includes the process of collecting and treating sewage sludge – seen as a by-product generated during wastewater treatment or in production and livestock production. Most of these sludge contains high levels of toxic heavy metals such as Cu, Mn, Zn, Ni, Cd, Pb, Hg that need to be treated. The purpose of the process is to reduce the number of harmful substances and the number of pathogenic microorganisms present in the solid before being discharged into the environment, avoiding the affected environment and human health.

Industrial sludge treatment definition and source of industrial sludge

Industrial sludge exists in liquid form, as a paste, or as a dry compacted sludge into a solid mass. Depending on the type of sludge, there will be different processes and treatment methods. What types of industrial sludge are there?

Classification of sludge treatment: properties of industrial sludge types

In the process of industrial sludge treatment, the classification of sludge will help us determine the appropriate and regulated treatment method because the properties and characteristics of different types of sludge will not be the same. Specifically, industrial sludge includes three main types as follows:

What is the importance of sludge treatment? Main effects of industrial sludge

Industrial sludge is usually generated from manufacturing plants, livestock barns, farms. Most of these industrial sludges have a reasonably high toxic content index. However, there are many cases where untreated or poorly treated sludge and wastewater have been discharged directly into the environment in large quantities, causing severe and long-term consequences. Therefore, industrial treatment according to quality, environmental, and health standards is crucial. Specifically, there are two main effects as follows:

the importance of sludge treatment

As can be seen, the proper treatment of industrial sludge is the responsibility of each individual and organization to the law and an obligation and morality, contributing to protecting the natural environment and human health.

Regulations on industrial sludge treatment: periodical treatment time

Different types of sludge will be produced for each type of production and business, so the regulations and standards on industrial sludge treatment will also vary, including periodic processing time regulations. Sludge accumulation for a long time is easy to cause a foul smell. Worse, it can cause damage to the storage tank and leak water, affecting hygiene and increased maintenance costs. Therefore, the periodic industrial cleaning of industrial sludge according to the plan will ensure the safety and hygiene, the durability of the system, and the beauty of production facilities and factories.

Regulations on industrial sludge treatment

Here are some general standards in sludge treatment:

Periodic collection and treatment of industrial sludge also help businesses quickly check the system’s status to promptly detect problems and increase the life of the drainage system and the sludge tank.

The above article shows that industrial sludge treatment in production and livestock processes dramatically affects the quality of the environment and human life. To perform their duties well, organizations need to assess the level, classify sewage sludge and select appropriate treatment methods according to environmental standards. Currently, most of these stages are performed by reputable service providers to bring the best efficiency with an optimal solution.
