    Collecting and treating industrial sludge is an important step for sustainable production, which does not harm the environment and is safe for human health. So what is industrial sludge treatment? The following article will help you learn an overview of industrial waste treatment.

    What is sludge treatment? Composition of sewage sludge
    Industrial sludge is the waste produced after an industrial wastewater treatment process. The composition of industrial sludge has an unpleasant odor and often contains heavy metals, hazardous wastes to the environment and health. The industrial sludge treatment step is extremely complicated and difficult, but very important. This step helps to ensure that the waste meets environmental protection requirements.

    Classify and industrial sludge treatment effectively and in accordance with regulations
    Classification of industrial sludge treatment will make collection and treatment easier. Currently, there are three ways to classify industrial waste. The first is biological industrial sludge, followed by hazardous industrial sludge and finally non-hazardous industrial sludge.
    1.How to treat biological industrial sludge treatment to save money?
    Bio-industrial sludge is a non-toxic, but foul-smelling sludge. This type of sludge treatment is easy to handle. Enterprises and companies can mix biological industrial waste sludge with peat or lime dust, EM preparations, microbial cultures... to create synthetic organic fertilizers. The main component of these organic fertilizers contains up to 70% of sewage sludge, so the cost of this fertilizer will be cheaper but the quality is equivalent to other fertilizers on the market today.
    2. Dispose of hazardous industrial sludge treatment in accordance with regulations
    It is mandatory to collect and treat hazardous industrial sludge treatment before discharging into the environment. Because hazardous industrial sludge contains many heavy metals such as: Se, Al, As, His, Mn, Zn, Ni, Cd, Pb, Hg ... These metals will be dangerous to human health and the environment. environment, can even have very long-term effects if not handled carefully.
    3. How to treat non-hazardous industrial sludge - sludge treatment?
    These non-hazardous industrial sludges can be treated without treatment and are used for a variety of purposes.

    Sources of industrial sludge treatment generation: Current situation of industrial waste treatment
    The sludge treatment, harmful waste is not only important in industries. In daily life, it is still necessary to pay attention to the treatment and collection of waste and sludge. Because every day, service industries and households generate hazardous waste and sludge to the environment.


    In daily life, hazardous waste sources arise such as: waste from fluorescent lamps, damaged batteries, batteries, waste containing paints, adhesive varnishes, printing inks, sealants or pesticides.

    The service industry also generates hazardous wastes such as chemotherapy, film coating, medical, radioactive hazardous waste, etc. Every year, the health sector generates about 21,000 tons of marine waste.

    Most industries generate hazardous industrial waste and sludge, but not all industries generate hazardous waste. Which industry will produce that type of sludge, can be based on the origin of the waste to find the appropriate treatment of industrial sludge.

    • Mineral field produces industrial sludge and special oily waste, iron ore, sulfide ore residue, tar residue...

    • The field of mechanics produces grease deposits, oil separators, asbestos residues, petroleum residues, oil separator waxes, sludge or residues containing organic halogens...

    • The power industry also generates toxic industrial wastes which are electronic devices with PCBs, CFCs, HCFCs, HFCs, asbestos...

    Each sector, industry and type of waste will have its own regulations and treatment criteria. You can refer to other articles to better understand how to treat industrial sludge.
