    How to Effectively Treat Wastewater from Steel Industry
    Category : Steel Industry
    The water usage in the steel industry ranges to a variety of processes and operations; the large amount of water used in the industry is bound to produce as much of wastewater, containing suspended solids and many other dissolved substances and chemicals.

    The quality of wastewater also depends on processes where the water is used or the purpose of it. Let’s take a look how wastewater management in steel industry functions and how does VASUNDHARA contributes its bit to make it effortless.

    Breaking down the composition of wastewater from Steel industry
    The wastes produced by the steel industry have physical and chemical effects on receiving streams, which are different from municipal sewage and organic industrial wastes. The wastewater composition of the industry includes:

    Oil and Grease
    Total Suspended Solids
    Surfactants
    Iron
    Chromium
    Aluminum
    Zinc
    Chlorides
    Sulfates
    These constituents of significance are recycled by RO and other treatment processes (which are mentioned below), to put it back into the industrial process.

    Treatment of wastewater
    The wastewater from the steel industry is subjected to various treatment options. The basic treatment of wastewater involves a combination of physical, chemical, biological and operation for the elimination of solids, organic matter etc. As per the increasing water treatment level, the treatment degrees are divided into:

    Preliminary
    Primary
    Secondary
    Tertiary
    1.Preliminary treatment
    The coarse solids and other large materials from the raw wastewater are removed by the process of Preliminary treatment.

    2.Primary treatment
    Primary Treatment Involves Various Physical-Chemical Processes like:-

    Physical Processes:
    Flocculation
    Sedimentation
    Dissolved Air Floatation
    Clarification
    Chemical Processes:
    Neutralization
    Precipitation
    3.Secondary treatment
    The secondary treatment uses mechanical treatment like:

    Activated Sludge Process
    Biological filters
    Trickling filters
    Rotating biological contactors
    Anaerobic Treatment systems
    4.Tertiary Treatment
    Membrane Technology
    Considering the sustainability of the environment, the membrane technology is fruitful and is also result-oriented for the treatment of industrial effluents. Today, this technology has a big role in wastewater treatment worldwide. During the last few years, the use of membrane technology has been substantial, along with the growth of a variety of newer versions of membrane technology.

    These steps in wastewater treatment from steel industry plays a crucial role in recycling and reusing the water resources.

    We offer excellent water treatment and recycling technology that adapts to the changing needs of our customers.

The Difference Between SBR, MBR and MBBR Sewage Treatment Plants

Image
The Difference Between SBR, MBR and MBBR Sewage Treatment Plants Sewage treatment plant is a process which separates contaminants or unwanted dissolved materials from waste-water. There are various  sewage treatment plants  for different purposes. Each has their own process to treat wastewater. Let us discuss the difference between SBR, MBR, and MBBR Sewage Treatment Plants today. SBR Sewage Water Treatment Plant  (SBR-Sequencing Batch Reactor) – is an activated sludge process used for waste-water treatment. To reduce the organic matters, oxygen is bubbled through the mixture of waste-water and activated sludge. MBR Sewage Water Treatment Plant  (MBR-Membrane Bio Reactor) – is the combination of the membrane process and a biological waste-water treatment process. It is one of the most widely used processes. MBBR Sewage Water Treatment Plant  (MBBR-Moving Bed Biofilm Reactor) – is a biofilm process which requires less space than activated sludge systems. This pro...

How to Know If Your Septic System Is Failing::

Look for these symptoms to determine if you have a serious problem: Sewage backup in your drains or toilets. This is often a black liquid with a disagreeable odor. Slow flushing of your toilets. Many of the drains in your house will drain much slower than usual, despite the use of plungers or drain cleaning products. Surface flow of waste water. Sometimes you will notice liquid seeping along the surface of the ground near your septic system. It may or may not have much of an odor associated with it. Lush green grass over the absorption field, even during dry weather. Often, this indicates that an excessive amount of liquid from your system is moving up through the soil, instead of downward, as it should. While some upward movement of liquid from the absorption field is good, too much could indicate major problems. The presence of nitrates or bacteria in your drinking water well. This indicates that liquid from the system may be flowing into the well through the ground ...

MBBR Technology in Wastewater Treatment

Image
Moving bed biofilm reactor (MBBR) is a biological technology used for the wastewater treatment process suitable for municipal and industrial applications. Another common name is the moving bed film reactor. It was invented in the 1980s. MBBR offers an economical solution for  wastewater treatment . STP MBBR technology is the use of a moving bed biofilm reactor in sewage treatment plants. MBBR wastewater treatment system enables efficient results of the disposal using low energy. The technology is used to separate organic substances, nitrification and denitrification. MBBR design is made of an activated sludge aeration system. The sludge is collected on the plastic carriers which have a large internal surface area. The surface area in the carriers optimizes the contact of water, air, and the bacteria. MBBR activated sludge is the application of MBBR media to an overloaded treatment plant when upgrading. MBBR  is applicable to the different quality of wastewater treat...
