Industrial water treatment is a process used in the present industrial processes and has the common goal of reducing as much harm to the environment as possible and also conforming to the regulations laid down by different bodies. A good system of solution, purification, and management of industrial wastewater not only preserves sources of water in the natural environment but also reuses the water that is used by industries.
What is Industrial Wastewater Treatment?
Industrial wastewater treatment involves all the activities that are needed in dealing with water that has been polluted in one way or another by industries. It is mainly used for processing and requires some amount of purification to eliminate chemical agents, pollutants like heavy metals, and organic content before being released into the environment or used again within the manufacturing company.
Various Methods for Industrial Water Treatment
Some of the industrial water treatment methods have associated advantages and applications. These methods include:
Physical Treatment: This process involves physical clarification procedures that include sedimentation, filtration, flotation, or any other process that achieves the elimination of suspended particles within it or on its surface.
Chemical Treatment: This method involves the use of chemicals in the removal of contaminants. In general, different methods are used such as coagulation, flocculation, and precipitation.
Biological Treatment: Uses microbial action to assimilate organic chemicals. This method involves aerobic and anaerobic treatment methods for sludge stabilization.
Membrane Filtration: Utilizes a selectivity of semi-permissive membranes to filter impurities out of water. The main methods include reverse osmosis ultrafiltration and nanofiltration.
Advanced Oxidation Processes (AOPs): Utilize chemistry where highly reactive species are formed for breaking down complex organic pollutants. Some of these are ozonation AOPs, UV-based AOPs, and Fenton-based AOPs.
Which Method Is Best and How Does It Work?
Out of all the methods listed, Membrane Filtration is generally accepted as the most effective in the course of industrial wastewater treatment due to its capabilities. Here’s how it works:
Reverse Osmosis (RO): Employing force to push purified water through a thin membrane porous to only a limited number of particles like ions, molecules, and large particles.
Advantages:
It is designed to filter out numerous unwanted particles and materials.
Hydroex produces high-quality effluent suitable for recycling and reuse in industries.
Applications:
Ideal for sectors belonging to, pharmaceuticals, food and beverage producing industries, and electronic product manufacturing industries.
Ultrafiltration (UF): Specifies a membrane operation, whereby solid particles and dissolved materials are underfelt from water.
Advantages:
H2O plus is proven to work effectively in the removal of bacterial viral and suspended materials.
Compared to reverse osmosis which consumes much more energy, the energy intake of the process is relatively low.
Applications:
Appropriate to be used in pre-treatment processes and all processes where very high levels of purity are desired.
Ready to Choose the Best Industrial Wastewater Treatment Method?
Water treatment selection is based on the type, concentration, and sort of pollutant in the industrial water to be treated, regardless of the pollutants in the industrial water, the quality of the water after treatment, or the preferred method of treatment.
In light of this, membrane filtration—particularly reverse osmosis—and ultra-filtration stand out due to their effectiveness in eliminating a variety of pollutants while producing high-grade wastewater.
Selecting the best industrial wastewater treatment technique helps ensure that water use complies with legal regulations, protects water as a resource, and protects the environment.
