Large volumes of water are used by a lot of industries for several manufacturing operations. Due to these operations, the water becomes contaminated, and hence, the industries require quality wastewater service to treat the water before discharging it.
Wastewater treatment plants are designed for the purpose of disposing of the generated or removed solids during the process and converting liquid waste into an acceptable final effluent. Industries require special wastewater treatment plants that remove pollutants like heavy metals or phosphorus from the water.
The proper engagement of the wastewater treatment cycle ensures that other water users have a source that meets their needs of water for all sorts of uses.
The Impact of Industrial Activities on Wastewater Generation
Overall, it is estimated that industrial activities consume around 5 to 20 percent of the total water. Several industrial processes such as production, heating, cooling, rinsing, and cleaning use up quite a lot of water resulting in the generation of a substantial proportion of the total wastewater.
Mining is said to be one of the major sources of unregulated wastewater discharge. In developing countries, approximately more than 70 percent of the untreated industrial waste is dumped into the waterways, and it pollutes the usable water supply.
When this waste seeps into the ground, it also results in the contamination of aquifers and wells. In addition to that, the discharge of toxic mine waste may also lead to persistent environmental damage.
To develop a closed water usage system and prevent the contaminants from entering the wastewater stream, you must take the necessary steps. These steps would include getting the relevant wastewater service to match your needs.
About Wastewater Services
Water is an essential component of the domestic, industrial, and commercial centers. A large amount of water is used daily, which during the process is most likely to become contaminated and not fit for drinking purposes.
Wastewater is also water; however, about 0.1% of its impurities are harmful to the human body. Wastewater services are there to make this water drinkable and safe to use.
SHARC is one of the effective wastewater recovery and treatment plants that focuses on properly treating wastewater before releasing it into the environment. These are specialized water plants that have an appropriate step-by-step mechanism and are usually installed in commercial areas as well as flats or apartments.
SHARC offers one-unit water treatment network installments. Ensuring all the polluted wastewater gets purified and detoxified through proper filtration, water can be made available to a more significant number of consumers, thereby reducing its shortage.
The Steps for Wastewater Treatment
Since the contaminants of industrial wastewater vary a lot, the required water environment services for wastewater treatment vary too. Nevertheless, the basic steps for wastewater treatment are said to be the same for both municipal and industrial wastewater.
Let’s shed some light on the steps that are used by some of the top providers of water environment services.
Step 1: Screening
Screening of the wastewater is the first step of the wastewater treatment process. It serves the primary purpose of removing solid materials that may cause damage to other process equipment, resulting in the reduction of the efficiency of the whole system.
Step 2: Primary Separation and Clarification
As the name indicates, the process of clarification removes the suspended solids from wastewater, creating a clarified liquid effluent for a number of downstream treatment processes.
Listed down below are the two types of wastewater clarifications.
- Primary Clarification: This clarification process is carried out before the biological treatment stage, and it removes solids from the wastewater.
- Secondary Clarification: This clarification process is carried out after the biological treatment, and it rapidly returns the activated sludge to the aeration tank.
The separation processes of solids are widely used in wastewater treatment plants. These processes are considered to be very critical in the preparation of industrial process water and in the pre-treatment of several types of wastewaters as well. We also offer Drain water heat recovery services as well.
Step 3: Aeration
Aeration is said to be a critical stage in the activated sludge process. Depending upon the provider of wastewater service and as per the situation, several methods of aeration are adopted. For a clear understanding, some of these aeration methods are listed down below.
- High-rate Aeration: This aeration process operates in the log growth phase, and in this process, excess food is provided to the biomass population via recirculation.
- Conventional Aeration: To produce an acceptable effluent in BOD, this process is considered as the most commonly activated sludge design used by municipalities as well as the industry operations.
- Extended Aeration: These aeration plants operate in the endogenous phase. However, they tend to use a long period of oxidation for the reduction of effluent BOD levels. The capital and operating costs for this plan are higher.
Step 4: Secondary Clarification
Since most surfaces are negatively charged. The finely divided particles that are suspended in the surface water tend to repel each other. Hence, the secondary clarification comprises a coagulation process followed by a flocculation process.
Step 5: Disinfection
The wastewater coming out from an industrial facility. Would probably carry a variable and broad range of contaminants, including chemical oxygen demand and BOD, etc.
Ozone, as well as the UV and other biological or chemical processes, have the tendency to treat complex industrial wastes. The UV disinfection process is rated to be environmentally safe. And, is recognized to be highly effective on several pathogens, including viruses.
In addition to UV disinfection, chlorine and its derivatives are also quite versatile chemicals for the treatment of industrial wastewater.
Step 6: Disposal of Solids
The disposal of solids that are generated by industrial sewage is an important step. It depends upon several factors such as the geographical location, the sludge characteristics as well as government regulations. Incineration, landfill, land application, and reclamation are some of the final disposal methods.
Conclusion About Wastewater
All in all, choosing a quality sewage service provider & water heating systems like SHARC may provide you with several benefits. These benefits would not only include the protection of your equipment. But, will also help you create a positive impact by protecting the environment. Moreover, this may be able to help you to save costs as well.
