Efficient Sludge Dewatering with Multi Disc Screw Press Technology

Tired of high operational costs and maintenance headaches from your sludge dewatering process? Dynamic Equipment brings you a revolutionary, energy-efficient solution—the Multi Disc Screw Press. Designed for superior solid-liquid separation in ETPs and STPs, our technology ensures lower power consumption, minimal maintenance, and a drier sludge cake, significantly reducing your overall cost of ownership.

Understanding Sludge Generation in Your Treatment Plant

A crucial first step in selecting the right dewatering equipment is accurately estimating the volume of sludge your plant generates. This is typically a percentage of your plant’s total treatment capacity.

Typical Sludge Generation Rates:

Example Calculation for a Sewage Treatment Plant (STP)

Sludge Generation Rate: Assuming a conservative 1.5% for a normal STP. Daily Sludge

Daily Sludge Volume: 1.5% of 1000 m³/day = 15 m³/day.

A small river named Duden flows by their place and supplies it with the necessary regelialia. It is a paradise

Required Machine Capacity: 15 m³/day ÷ 20 hrs/day = 0.75 m³/

The Multi Disc Screw Press: How It Works

Our Multi Disc Screw Press dewaters sludge in three efficient stages:

Flocculation: Sludge is conditioned with polyelectrolytes in a mixing tank to destabilize surface charges and form sturdy floes.
Thickening: The flocculated sludge enters the press. In the initial thickening zone, a significant portion of free water is released through the gaps between the stationary and rotating discs.
Dewatering: The thickened sludge is gradually pushed by the tapered screw towards the pressure plate. This creates increasing pressure, squeezing out remaining moisture to form a solid cake with a dryness of >20% w/w solids.

Choosing the Right Technology: A Head-to-Head Comparison

Selecting the best dewatering technology is critical for operational efficiency and cost management. Here’s how the Multi Disc Screw Press stacks up against a Centrifuge and a Filter Press for a typical 10 m³/hr feed flow.

Conclusion: The Multi Disc Screw Press is the undisputed leader in low operational cost, minimal maintenance, and quiet, automated operation, making it the most cost-effective solution over the equipment’s lifetime.

Why Choose Indus Multi Disc Screw Press?

An STP and its sludge dewatering unit are not separate machines; they are two halves of a single, integrated process.

The Problem with Multiple Vendors: If your STP and dewatering press are from different suppliers, you face a endless cycle of blame. If the dewatered cake is too wet, the STP vendor will blame the press, and the press vendor will blame the STP’s sludge quality. You are left in the middle, with a non-performing plant and no one to take responsibility.

Our Integrated Solution: When you buy from Indus Ecowater, we are the single point of accountability. We design the entire system—from the inlet to the final sludge cake—to work in perfect harmony. The biological process, the flocculation system, and the dewatering press are all optimized for each other. You get one warranty, one service contact, and one team guaranteed to make your entire plant perform.
