Water and wastewater treatment solutions - make life better.


Ingersoll Rand Richler products provide the right products for your application - making life better

We help you meet common industry challenges

population growth

Population growth and climate change will continue to exert pressure on water shortage areas. With the increase of average revenue and the change of customers' expectations, customers' demand for environmental improvement may increase.

environmental footprint

The construction cost of sewage treatment plant is high, and it depends on a large amount of land area to build sedimentation tank and aeration tank. With the increase of demand, the sewage treatment plant needs to be expanded to improve its treatment capacity. Business owners must meet their needs while maintaining a small and low impact footprint.

Legal compliance

From primary sedimentation to sludge treatment, quality must be ensured to meet increasingly stringent environmental regulations.

Invest in the future

Investing in the right technology will provide a rapid return on investment, improve productivity, reliability and drive efficiency.

energy consumption

Energy consumption is one of the largest expenditures in wastewater treatment. It is estimated that 3% to 15% of the electricity in a country is used for wastewater treatment every year. It is imperative to improve efficiency.

Lack of skills and shortage of personnel

Like many other industries, sewage treatment plants face the problem of personnel shortage. To properly treat wastewater, highly efficient, productive and skilled workers are essential. Without workers, repair opportunities and other abnormalities may be ignored.

Sludge management

Sludge is a residue produced in the process of physical, chemical and biological treatment. A major environmental challenge in wastewater treatment is the sustainable disposal of excess sludge generated in the process.

Working with a single supplier can help reduce costs, simplify management processes, and improve operational efficiency – and even drive innovation and development.

Free choice

Ingersoll Rand provides innovative and key industrial solutions in the field of municipal sewage and industrial water treatment. It has a series of compressors, blowers, pumps and vacuum products, covering many award-winning brands.

Our air solutions and product portfolio are designed to improve efficiency and productivity, even in the most complex operating conditions.

Sewage treatment plants provide clean water to millions of people around the world. Our products play a vital role in this regard, driving various sewage treatment processes to remove a variety of harmful substances and provide the highest possible water quality.

We offer a wide range of innovative products, services and solutions to improve energy efficiency and productivity at each stage of the treatment process.

The aeration system consumes the most energy in the sewage treatment plant (accounting for more than 50% of the whole electricity charge), so improving the efficiency can greatly reduce the energy cost. Energy accounts for 75% of the total cost, so technologically advanced aeration equipment will play a vital role, which can not only reduce the carbon footprint, but also significantly reduce the life cycle cost.

The scope and process complexity of the environmental protection industry make it extremely important to select reputable and experienced suppliers for each application.
