Treating industrial and municipal wastewater leads to the generation of sludge that needs to be treated prior to disposal. One of the most eco-efficient sludge treatment technologies is the Multi Disc Screw Press (MDSP) which is now widely used for sludge dewatering due to low energy demand, ease of maintenance, and space saving structure.
This article will discuss the top five benefits of MDSP, compare its performance with traditional equipment, and present A1 BLOWERS Pvt. Ltd. as one of the foremost MDSP manufacturers designed for Indian industrial needs.
What is a Multi Disc Screw Press?
A Multi Disc Screw Press is a modern sludge dewatering unit that uses a rotating screw combined with layered discs to remove water from sludge. The gradual rotation of the screw results in sluggish movement of the screw which filters water through the discs. This design consumes less energy while maintaining high levels of effectiveness.
A1 BLOWERS Pvt. Ltd. specializes in manufacturing tailored MDSP units for various industries including,
- Food processing units
- Chemicals manufacturing plants
- Municipal sewage treating plants
- Textile and paper mills
These machines are tailored to the Indian market and achieve high efficiency coupled with long operational life and low maintenance costs.
1. Cost-Efficient Operation with Low Energy Consumption
Power consumption is one of the most important advantages of the Multi Disc Screw Press. Unlike centrifuges or belt presses which may require as much as 1–3 kWh, the MDSP only needs 0.2–0.5 kWh.
Why it matters:
- Lower electricity bills for industrial plants
- Reduced carbon emissions due to low energy consumption
- Sustainable waste management
An example of this savings can be seen at a medium-sized wastewater treatment facility. Those equipped with MDSPs from A1 BLOWERS Pvt. Ltd. have reported savings of up to 60% in daily power expenses compared to facilities using centrifuge-based systems.
2. Durable MDSP Components Result in Minimal Maintenance
The MDSP’s fewer moving parts are easier to maintain and result in less wear and tear. In contrast, belt presses are plagued by needing to frequently replace belts and centrifuges require a lot of maintenance due to their rapidly spinning parts.
Benefits of MDSP maintenance include:
- Corrosion resistant due to stainless steel MDSP construction
- Discs are kept sludge-free due to automatic self-cleaning systems
- Longer intervals between servicing and maintenance, typically only requiring 1-2 hours a week.
Rugged by design, especially suited for Indian conditions, A1 BLOWERS MDSPs slash maintenance expense by 30-40% compared to foreign machines.
3. Elevated Sludge Dryness Permitting Easier Disposal
MDSP outperforms traditional systems in dewatering efficiency. It nears belt presses and filter presses in solid content (15-20% and 18-25% respectively) by surpassing 20-30% solid content.
Why this matters:
- Reduced volume and expenses for disposal transporting sludge
- Increased efficiency in usage of space in landfills
- More efficient landfill usage
In an example with a municipal wastewater plant, MDSP units from A1 BLOWERS efficiently reduce 100 tons of wet sludge to 20 tons dry, resulting in significant economic and environmental benefits.
4. Space Saving Installations with Compact Design
MDSP machines unlike large centrifuge systems or belt presses which take up a large spatial footprint, these machines are modular and compact.
Best suited for:
- Limited spatial urban installations
- Small/medium enterprises
- Retrofit projects in older facilities
A1 BLOWERS MDSP units can be placed in as small as 2x3meter spaces, ideal for breweries, dairies, and textile mills.
5. Reduction in Chemical Usage for Enhanced Eco-Friendly Standards
Due to polymers and coagulants being used too heavily, conventional sludge dewatering systems face increased operational costs and waste of chemicals. Mechanical compression used by MDSP drastically reduces the demand of polymers by up to 70% compared to belt presses.
- Financial and environmental advantages:
- Reduced chemical expenses
- Reduced prescription impact
A1 BLOWERS uses a smart polymer dosing system in their MDSP models, and achieves optimization. In textile factories, for instance, MDSP machines consumes only 2-3kg of polymer per three tons of sludge while some belt presses require 7 kg.

Frequently Asked Questions
1. What is the electrical consumption of an MDSP?
MDSP comes out considerably advantageous with only 0.2 to 0.5 kWh of electricity being consumed, far less than industry standards.
2. Does MDSP require frequent servicing?
Not at all, the machine features a simple clean self-maintaining structure.
3. What is the final dry weight of the sludge after treatment?
Post treatment with MDSP, the target of 20–30% solids content is easily attainable, significantly reducing the cost and complexity involved in disposal.
4. Is it suited for smaller business facilities?
Absolutely not only small, but even medium sized industries can benefit as well due to its compact spatial requirements.
5. Is the amount of required polymers and chemicals high?
Absolutely not, MDSP needs only half to a third of the amount of chemicals needed when compared to conventional machines, making the system even more efficient.
