Roto-Press: Revolutionizing Wastewater Treatment with Rotary Fine Screens and Dewatering Presses
In the realm of environmental and water treatment, efficient and reliable solid-liquid separation is paramount. One innovative technology rising to this challenge is the Roto-Press, a synergistic combination of rotary fine screens and dewatering presses, championed by Dontech, Inc.
What is a Roto-Press?
The Roto-Press is a cutting-edge solution that integrates two key technologies:
- Rotary Fine Screens: These screens are essential for removing suspended solids from wastewater streams, particularly those with smaller particle sizes. Their rotating design allows for continuous and efficient filtration, significantly reducing the load on downstream treatment processes.
- Dewatering Presses: These presses are designed to extract water from the captured solids, producing a dewatered cake. This cake can then be disposed of more efficiently and safely, minimizing the volume of sludge requiring further treatment.
Benefits of the Roto-Press:
By combining these technologies, the Roto-Press offers several advantages over traditional wastewater treatment methods:
- Improved Efficiency: The continuous operation of the rotary screens and presses ensures a high throughput, maximizing the volume of wastewater treated per unit of time.
- Reduced Sludge Volume: The dewatering process significantly reduces the volume of sludge, leading to lower disposal costs and a smaller environmental footprint.
- Enhanced Solids Recovery: The Roto-Press can effectively recover valuable solids from wastewater, potentially leading to resource recovery and beneficial reuse.
- Reduced Chemical Use: By effectively separating solids from wastewater, the Roto-Press minimizes the need for chemical flocculants and other treatment chemicals.
- Minimal Maintenance: The robust design of the Roto-Press ensures minimal downtime for maintenance, contributing to its reliability and long-term performance.

Roto-Press Exercise:
Problem: A municipality is struggling with managing its wastewater treatment plant's sludge disposal costs. They are considering using a Roto-Press system to reduce the sludge volume. The current sludge volume is 500 cubic meters per day. The Roto-Press system promises to reduce sludge volume by 75%.
Task:
- Calculate the expected daily sludge volume after implementing the Roto-Press system.
- Based on the reduced sludge volume, explain how the Roto-Press can benefit the municipality in terms of cost savings and environmental impact.
Exercice Correction
1. **Sludge volume reduction:** 500 cubic meters * 0.75 = 375 cubic meters reduction **Expected daily volume after Roto-Press:** 500 cubic meters - 375 cubic meters = 125 cubic meters 2. **Benefits:** * **Cost Savings:** Reducing the sludge volume by 75% will significantly decrease the costs associated with sludge transportation, disposal, and treatment. This could translate into significant financial savings for the municipality. * **Environmental Impact:** Smaller sludge volume means less landfill space required, reducing the environmental footprint. Additionally, the potential for solids recovery and beneficial reuse further contributes to a more sustainable approach to wastewater management.
