Energy-saving control to reduce costs and improve efficiency. Focusing on the entire process of water supply and wastewater treatment, INVT leverages advanced variable frequency drive and closed-loop control technologies to help water utilities optimize system energy efficiency and stabilize process operations, fully ushering in a new era of low-carbon digital water management.
Covering the full-process scenarios and directly addressing energy-consumption pain points.
In modern water treatment processes, the electricity consumption of pump and fan loads accounts for over 35% of total power usage. Due to the coarse adjustment and extremely high energy consumption of traditional fixed-frequency operation, fine-tuned control through variable frequency drives has become an industry imperative. INVT solutions are deeply adapted to the following two core business scenarios:
Municipal Waterworks: Covering the complete process of intake → coagulation → sedimentation → filtration → disinfection → water delivery. High-performance VFDs precisely drive intake pumps, coagulant dosing pumps, backwash pumps, and delivery pumps, perfectly matching dynamic variations in source water level and flow to ensure process continuity.
Municipal Wastewater Treatment Plants: Covering bar screen retention, wastewater lifting, grit removal, biological aeration, secondary clarification, and sludge treatment. Through intelligent speed regulation of lift pumps, aeration blowers, and return sludge pumps, the system easily handles around-the-clock severe load fluctuations, ensuring stable compliance of effluent quality indicators.
In-depth mastery of dedicated control algorithms for fans and pumps. Built-in high-precision PID closed-loop control, supporting mainstream industrial communication networking.
Providing a complete range of drive products covering medium and low voltage. The GD5000 series medium-voltage VFDs are specifically designed for large pump sets; the GD28, GD290, and GD350A series low-voltage VFDs are designed for small to medium-sized pumps.
The solution has been successfully implemented in global landmark projects such as a large-scale waterworks in Russia and the Xinzheng Waterworks in China. The system achieves an overall energy saving rate of 24%–27%, with an average daily power saving of over 2500 kWh, significantly shortening the equipment investment payback period.
