Water is the most precious resource on Earth, yet it is under severe threat due to pollution and overuse. Did you know that 80% of global wastewater is discharged untreated into the environment, contaminating rivers, lakes, and oceans? This untreated water contains harmful levels of BOD (Biological Oxygen Demand) and COD (Chemical Oxygen Demand), which indicate the presence of organic pollutants and chemicals. For instance, safe drinking water should have a BOD level of less than 5 mg/L and a COD level of less than 10 mg/L. However, industrial and domestic wastewater often exceeds these limits, posing severe health risks.
With the global population expected to reach 10 billion by 2050, water scarcity is becoming a pressing issue. This blog explores the main technologies in waste water treatment, their benefits, and how they can help solve the global water crisis.

The Daily Life Water Crisis
Water is essential for all living organisms, but its misuse and pollution are creating a global crisis. From industries to households, wastewater is generated daily, mixing with plastics, chemicals, and other pollutants. This contaminated water not only harms ecosystems but also leads to severe health problems like cholera, dysentery, and cancer.
The main challenges include:
- Industrial Waste: Factories release toxic chemicals and heavy metals into water bodies.
- Plastic Pollution: Microplastics are now found in 90% of bottled water.
- Lack of Treatment Infrastructure: Many regions lack proper wastewater treatment facilities.
Signicent performs patent invalidity searches, identifying prior art to challenge wastewater treatment patents, ensuring stronger IP protection and supporting legal disputes with solid evidence.
The Growing Challenge: Understanding the Cost of Water Pollution
Water pollution is a major financial burden in addition to being an environmental issue. There are a number of reasons why this problem is so expensive:
- Public Health & Environmental Degradation: Contaminated water sources spread diseases and harm ecosystems, impacting fisheries, agriculture, tourism, and increasing global restoration costs.
- High Treatment Costs & Compliance Burdens: Businesses face strict environmental regulations, requiring advanced wastewater treatment technologies that raise operational expenses and industry compliance challenges.
- Pollution & Complex Contaminants: Heavy metals, microplastics, and industrial chemicals require advanced purification solutions, making wastewater treatment more resource-intensive and technologically demanding.
- Aging Infrastructure & High Energy Consumption: Outdated treatment plants need costly upgrades, while traditional purification methods consume massive energy, increasing operational expenses and environmental impact.
