[Case Study] Low-Pressure Wastewater Treatment (Energy-Saving Screw Blower Technology)

Introduction to the background of why the overseas water company "ZS" was selected for numerous awards.

We would like to introduce a case where the Northumbrian Water Company, which has received various awards overseas, implemented Atlas Copco's energy-efficient screw blower. The company originally used four lobe-type blowers for aeration, but due to reliability issues with one unit, they considered next-generation high-efficiency screw blowers that can reduce energy consumption by up to 30% compared to lobe-type blowers. 【Installed Products】 ■ Oil-free screw blower ZS ■ Installed motor output: 18.5–160 kW (25–200 hp) ■ Operating pressure: 0.3–1 bar (e) (4–14.5 psig) ■ Capacity (FAD): 75–1292 L/s (271–4631 m³/h) After the introduction of the "ZS," a 20% improvement rate was confirmed. The company decided to switch all blowers to our equipment. We also have the latest model with inverter functionality, the 'ZS 4 VSD+', and the turbo blower 'ZB series.' Please take a look at our catalog. *For more details, please refer to the catalog or feel free to contact us.

Thesis "Theoretical and Experimental Study of Twin-Screw Blowers"

Free gift of a paper on the energy efficiency of twin screw blowers!

"Theoretical and Experimental Study of Twin Screw Blowers" is a paper on the theoretical and experimental research regarding the energy efficiency of twin screw blowers compared to rotary lobe blowers. It examines the energy studies of conventional "Roots" blowers and screw blowers. The experimental results show a strong correlation with fundamental thermodynamic laws, demonstrating that screw blowers can be more efficient machines, with energy consumption reduced by up to 50%.

Data on Energy Saving from Changing Aeration Blowers in ActiContact

A detailed explanation of energy-saving measures related to the change of aeration blowers in activated sludge contact systems!

This document introduces the equipment overview and improvement efforts at the Akuchikontakuto (contact oxidation biological tank) of the Chuo Pulp Industry Co., Ltd. Kawauchi Plant. By changing from a roots blower to an inverter-type oil-free screw blower, we were able to reduce noise levels while simultaneously achieving energy savings. The document clearly presents the background leading to the equipment installation, a comparison of equipment specifications, and actual energy savings using diagrams and tables. [Contents] ■ Overview of the Akuchikontakuto at the Kawauchi Plant ■ Background leading to equipment installation ■ Overview of the INV-type screw blower ■ Operational status and issues ■ Confirmation of effects from blower replacement *For more details, please refer to the PDF document or feel free to contact us.
