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

[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 Northumbrian Water, 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. 【Products Introduced】 ■ 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. All blowers will be switched to our equipment. We also have the latest model "ZS 4 VSD+" with inverter functionality 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"

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

Data on Energy Saving from Changing Aeration Blowers in ActiContact

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

This document introduces the equipment overview and improvement efforts at the Akuchicontact (contact oxidation biological tank) of the Chuetsu Pulp & Paper Co., Ltd. Kawauchi Plant. By changing from a roots blower to an inverter-driven 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 Akuchicontact at the Kawauchi Plant ■ Background leading to equipment installation ■ Overview of the INV screw blower ■ Operating conditions and issues ■ Confirmation of effects from blower replacement *For more details, please refer to the PDF document or feel free to contact us.

Oil-free volumetric screw blower "Atlas Copco ZS Blower"

Oil-free volumetric screw blower "Atlas Copco ZS Blower"

To achieve continuous internal compression by screws, it has high adiabatic efficiency and is energy-saving.

The "Atlas Copco ZS Blower" is an oil-free volumetric screw blower that generates compressed air without oil by rotating two opposing screw shafts directly connected to an electric motor. This technology consists of a packaged blower that houses all necessary auxiliary equipment for blower operation, including an intake filter, screw compression section, direct-coupled reduction gear, check valve, silencer, and oil pump, along with a blower control panel for controlling the rotation speed. 【Features】 ■ High efficiency and energy-saving ■ Reduced electrical losses due to direct coupling with the motor ■ Minimal efficiency drop when controlling rotation speed ■ Fewer auxiliary components make maintenance and inspection easier, simplifying maintenance tasks ■ Construction technology certification obtained *For more details, please refer to the PDF materials or feel free to contact us.
