Some current regulations and criteria on industrial sludge treatment today

Industrial sludge treatment is a necessary step to ensure the safety of the environment and human health. The treatment of industrial sludge needs to comply with regulations and criteria promulgated by law. Today's article will talk about current regulations on waste and sludge treatment.

Regulations and criteria on industrial sludge treatment in accordance with the law

First, we will talk about the notes when dealing with sewage sludge. Next, we will review the regulations on the identification and classification of sludge and waste. Finally, how to industrial sludge treatment.

1.Sludge treatment - Before treating industrial sludge, it is necessary to pay attention to the regulations on collection and transportation of sludge

Waste sludge must be collected and transported to a centralized treatment site according to regulations. The process of industrial sludge treatment must comply with regulations issued by competent state agencies. The reuse of sewage sludge must ensure compliance with environmental protection regulations.

Legal regulations prohibit the discharge of untreated sludge into the environment. In addition, the regulation also prohibits businesses, factories and companies from exchanging, buying and selling sewage sludge.

According to Decree 155/2016/ND-CP on collection, classification, transportation and treatment of sludge, the process of collecting and transferring sludge must not cause dust, odors or release into the environment. Therefore, only organizations that have expertise and are qualified to provide services in accordance with the law are allowed to treat industrial sludge.

2. Sludge treatment - Before treating industrial sludge, it is necessary to pay attention to the regulations on the classification of waste sludge

Before proceeding with the sludge treatment, it is necessary to evaluate and identify the type of sludge. Depending on the toxic level of the sludge, select appropriate collection and treatment methods. The delimitation must comply with current regulations of the Ministry of Natural Resources and Environment.
Sludge generated regularly in construction, production, business and service activities must be identified, classified and registered for management. Waste source owners must strictly comply with their responsibilities for waste management and treatment of industrial sludge in accordance with current legal regulations.

Sewage sludge containing high levels of heavy metals such as Cu, Cr, As, Ni, Cd should be treated by functional units with licenses to practice hazardous waste management. With toxic industrial sludge arising from chemical manufacturing industries, metalworking needs to be handled carefully and rationally by a team of professionals.

Above are the regulations and criteria for industrial sludge treatment. In short, industrial sludge treatment needs to comply with regulations. This process must be carried out by companies, units with expertise and license to practice. Because if not handled well, toxic substances in the sludge will affect water sources, the environment, the air and human health.
