Throughout history, several industries, plants, and manufacturing companies have polluted natural water bodies by dumping their waste products into water resources. Industries should remove harmful elements present in the waste before dumping it into rivers and oceans. Thus, it is necessary to prevent contamination of water and the environment. Simultaneously, it will have adverse effects on people’s health. Industrial wastewater may include a variety of elements such as oil, chemical substances, heavy metals, etc. These pollutants can cause pollution of water and have negative effects on people’s health.

How Industrial Wastewater Affects Water Quality

When industrial wastewater gets discharged untreated into natural water sources, it will cause several degradations in water quality. Here are some bad effects of untreated industrial wastewater:

• Water Contamination

The wastewater that comes from industries consists of several types of pollutants, such as lead, arsenic, and magnesium, as well as foul odours. All these water pollutants have the capability of polluting water and making it harmful to human consumption. Therefore, it becomes crucial to clean the wastewater thoroughly from all the impurities using water purifiers and water cleaning techniques.

• Decreases Oxygen Level

When untreated industrial wastewater is dissolved into natural water sources, it will degrade the oxygen level in the water. It happens due to the reaction of unwanted and toxic elements in wastewater, like chemicals, metals, bad odours, etc. All these elements react with water, lower the oxygen level in water, and pollute it.

• Bad Effect on Aquatic Life

The effects of oxygen-deficient industrial wastewater will negatively influence the life of aquatic organisms, damaging the entire aquatic environment. The presence of inorganic waste, chemicals, and metals in industrial wastewater will increase the level of toxicity of natural water resources, which in turn will influence the life and even reproduction abilities of aquatic creatures.

• Groundwater Contamination

When non-processed industrial wastewater is used for farming or harvesting, it will affect the quality of groundwater and soil. Therefore, the utilisation of polluted groundwater is extremely dangerous for the natural water sources and people.

Thus, above are some bad effects of industrial wastewater on water sources.

Effect of Industrial Wastewater on Public Health

Many people get the adverse effects of industrial wastewater when they use it for drinking or any other purpose. Some vital effects of wastewater on the human body are as follows:

• Stomach and Skin Disorders 

When people drink the contaminated water that includes untreated wastewater elements such as harmful chemicals, metals, inorganic elements, etc., it will give rise to varied health problems in humans. In rural locations, most villagers consume untreated water containing industrial waste, which causes stomach ailments and skin disorders. It is therefore advisable not to drink or cook using untreated and processed wastewater since it is highly hazardous to human health.

• Affect Organs’ Functionality

Consumption of such water that is full of harmful chemicals, such as arsenic, lead, and many more, will have an impact on the performance of organs within our body, such as the liver, kidneys, lungs, and so forth. Moreover, the water components may bring about significant problems to one’s skin and also their respiratory system. For that reason, it is important to test the water before its use and ensure that untreated wastewater is not used for cooking purposes.

• Risk of Skin Problems and Cancer

Longer use of industrial wastewater, including heavy metals, chemicals, and other harmful elements, will lead to the risk of skin problems and cancer as well. Many villagers use or drink untreated water from rivers, wells, and natural sources that may include harmful chemicals and metals, which can develop several skin issues that can later turn into cancer problems. Hence, it is strictly prohibited to use untreated groundwater for drinking purposes.

• Developing Reproductive and Sexual Organ Problems

Drinking unprocessed or contaminated water can sometimes give rise to reproductive and sexual organ dysfunction disorders in humans. Sometimes, many women get hormonal imbalance issues during pregnancy if they drink contaminated water longer. Similarly, men may have male organ dysfunction issues due to the adverse effects of drinking polluted water. Hence, it can damage the reproductive system of the body, which can lead to varied mental and physical issues in the coming generations of humans.

Thus, above are some massive effects of drinking or using untreated industrial wastewater or groundwater on public health.

Prevention and Control Measures of Industrial Wastewater

Before you use industrial wastewater for personal or professional purposes, you should ensure that you have treated it well through standard procedures to remove its harmful chemicals, metals, and toxic elements.

Here are some prevention and control measures for industrial wastewater to treat it professionally.

1. Proper Treatment of Wastewater

Each industry or factory needs to make sure that its wastewater is treated to eliminate any hazardous chemicals, heavy metals, inorganic substances, foul smells, oils, etc., prior to releasing them into natural water bodies such as rivers, oceans, wells, lakes, etc.

2. Use of Industrial Water Cleaning Methods

Industries and factories should use or follow standard wastewater cleaning methods for removing industrial waste from water. Some standard procedures of purifying industrial wastewater are as follows:

• Use wastewater treatment equipment such as bar screens, grit tanks, sedimentation tanks, filters, cooling tower chemicals, and oil/grease traps.
• You may also use Industrial wastewater treatment equipment such as trickling filters, sequencing batch reactors, BOD clarifiers, etc. 
• Follow standard Methods of Wastewater Treatments such as Membrane Filtration (Reverse Osmosis or Ultrafiltration), Activated Carbon Filtration, Chemical Oxidation, etc.

3. Wastewater Treatment Technology

You should use the standard wastewater treatment technology methods for treating industrial wastewater, such as:

• Screening method to eliminate large solids and wastes from water
• Use the sedimentation process to remove suspended sediments. Remove oil and gas mixed in the wastewater using separators or skimmers. 
• The method of activated sludge will be used to remove the microorganisms present in the wastewater.
• The right filtration method using membranes such as NF (Nano filtration), UF (Ultrafiltration), and RO (Reverse Osmosis), etc., can be used for the removal of impurities, dirt, salts, and metals present in wastewater.

4. Water Conservation and Recycling

It is another significant method to manage industrial wastewater through conservation and recycling processes. For this purpose, you can implement the closed-loop water system to reduce the water discharge. Besides, you can recycle the wastewater for cooling and washing and use it for other industrial applications. Also, you can include the water-cleaning chemicals and other agents to purify and reuse wastewater for other purposes.

5. Testing and Monitoring

With regular monitoring and testing of wastewater or stored water, you can maintain the quality of water for the long term. For this purpose, you can install quality water purifiers and water quality monitoring systems that are effective in checking the quality of water periodically. Besides, the regular testing of water quality at parameters like pH, BOD, TSS, COD, etc., will also help in improving the quality of water.

Thus, above are some vital ways to preserve and control measures of industrial wastewater to reuse it and make it effective for public health.
