Wastewater, ETP, STP & WTP Treatment

Risansi Industries has been at the forefront of introducing progressive cavity (PC) screw pumps to the wastewater, sewage, and sludge treatment sector in India. Since the installation of our first pumps in 1979—used to feed sludge to filter presses in chemical industries—we have continued to lead the way with reliable and efficient fluid handling solutions for environmental and industrial applications.

With decades of hands-on experience, we offer customized PC pumps for a wide range of applications, including:

• Raw sewage water
• Primary and activated sludge
• Dewatered sludge (up to 6% solids)
• Flocculation agents
• Milk of lime, chrome water sludge
• Oil sludge and oil-water mixtures
• Acid/alkali sludge and neutralized acid sludge
• Electroplating, phosphatic, alkaline, and black liquor sludge
• Ammonia zinc and zinc acid sludge
• Hotel, agrochemical, and dairy waste

Our pumps are designed to handle both aggressive and viscous media, making them ideal for use in ETPs (Effluent Treatment Plants), STPs (Sewage Treatment Plants), and WTPs (Water Treatment Plants). With a commitment to performance, durability, and technical excellence, Risansi remains a trusted name in the treatment of complex wastewater and sludge streams.
