The Asia Pacific Region to Significantly Contribute to the Global Wastewater Treatment Industry Growth

Geographically, the Asia Pacific wastewater treatment industry is expected to witness a significant growth in the forecast period owing to the increasing demand for wastewater treatment from municipal and power generation industries in the region. Moreover, increasing municipal wastage, rapidly growing population, and stringent regulations on wastewater discharge in the region are contributing to the growth of the wastewater treatment industry in the Asia Pacific. Countries such as China, Japan, and India are expected to witness a significant growth in the wastewater treatment industry due to the increasing demand for efficient wastewater management solutions across industries including food, chemical, pulp and paper, and power generation, among others.

Wastewater Treatment: Market Segmentation

Wastewater treatment is a process in which wastewater is converted into an effluent that can be either reused or returned to the waterbody with minimal environmental issues. Wastewater contains a wide range of contaminants or pollutants, which are categorised as physical, chemical, and biological. Common pollutants include nitrogen and phosphorus-rich compounds, complex organic materials, and pathogenic organisms (bacteria, viruses, and protozoa). Synthetic organic chemicals, microplastics, radioactive substances, oil, sediments, and many other pollutants may also be present in wastewater.

Based on process, the industry can be divided into:

• Primary Treatment
• Secondary Treatment
• Tertiary Treatment

By type, the industry can be segmented into:

• Membrane Separation
• Biological
• Disinfection
• Sludge Treatment
• Others

The significant applications of wastewater treatment include:

• Municipal
• Industrial
• Agricultural

The regional markets for the product include:

• North America
• Europe
• Asia Pacific
• Latin America
• Middle East and Africa

Rapid Growth in Industrialisation and the Favourable Government Measures to Support Wastewater Treatment Plans to Bolster the Growth of the Global Wastewater Treatment Industry

Wastewater contains significant amount of toxicity which can be harmful to humans and the environment. Several waterborne diseases, including typhoid, cholera, dysentery, and schistosomiasis, remain widespread across many developing countries. Rapid growth in population, urbanisation, and industrialisation and the increasing prevalence of waterborne diseases are anticipated to propel the expansion of the wastewater treatment industry in the forecast period. Additionally, wastewater treatment has proven beneficial for various companies as it helps them minimise their expenses by enabling the reuse of water in industrial operations and reduce the waste processing cost. Moreover, stringent governmental regulations on treating wastewater and the rising focus on water quality and public health are expected to boost the demand for wastewater treatment during the forecast period.
