Welcome to Dewlink

Sludge Dewatering Pioneer

Inventors of Tubox ® & Swingmill ® technologies

Dewatering for a Cleaner World

Specialising in the research, design, development and supply of sludge dewatering devices and polymer make-up systems. 

Our Tubox.® & Swingmill.® unique designs represent the next generation of dewatering, utilising the latest technology with non-contact, non-abrasive components to provide superior performance, increased efficiency and diminishing maintenance costs.

Our compact modular systems are the most effective, efficient and economical dewatering machines on the market, dramatically reducing the cost of sludge and waste-water treatment.

Dewlink provides the advice and the solutions for all of your sludge and waste-water needs

Sludge Dewatering Systems


Polymer makeup system available for powder and emulsion. Efficient mixing and accurate dosing.


Mixing tank with high speed mixing tube, creating a collision effect leading to faster flocculation.


For thickening and dewatering sludge through pressure filtration and unique ring movements.


The complete sludge dewatering solution consisting of the MixCycle, Tubox and Swingmill.

Increasing Efficiency and Reducing Costs

reduce power comsumption

The high throughput capacity design allows the components to run at a consistently low speed, consuming very little power, making the Swingmill.® one of the most efficient sludge dewatering devices available on the market.


The efficiency and effectiveness of our system decreases polymer usage by approximately 30%.  Less polymer reduces operating costs and provides better overall results.

increase efficiency

A Combination of the Tubox.® & Swingmill.® technologies can improve the sludge handling capacity by approximately 20%.  Our dual screw configuration and pendulum ring motion allows a higher throughput capacity with an increase in the recovery rate of the solid.


The unique pendulum movement of the rings eliminates clogging, reducing wash down and maintenance costs. The non-contact, non-abrasive mechanism also reduces wear, increasing durability.


The versatile Tubox.® and Swingmill.® devices are suitable for a myriad of industries, being capable of successfully dewatering a wide variety of sludges. 

If it can flocculate, we can dewater it!


Our Sludge dewatering systems are fully programmable, with automated 24 hour start-stop unattended operations.  We reduce the labour costs and set-up time whilst offering you the ability to memory store different settings for different processes.

no deformation

Compared to traditional / conventional screw-presses, our non-contact, non-abrasive mechanism, increases the lifespan of the moving rings from 10,000 to 100,000 hours and the screw from 30,000 to 100,000 hours.


The flexibility of adjustment in the speed of the screws and the moving rings can capture more water and reduce the volume of the solids, all this without sacrificing throughput. A lower volume of solids offers reduced disposal costs and a greener / cleaner environment / world.

Latest Projects

We work with different Industries to solve their sludge dewatering problems.  Providing chemistry and dewatering to reduce volume for cheaper transportation and easy disposal.

We have many ongoing projects, whether it’s solving our client’s sludge problems, being involve in research and development of our polymer make-up and dewatering systems or conducting various test onsite within different Industries.  We are committed to provide the best and most effective solution to solve the problem of sludge dewatering and sludge removal.

Dewatering Container

A fully containerized Swingmill sludge dewatering solution with chemical dosing ready for shipping to a client.  It is fully automated with integrated conveyor system and forming part of a new waste water treatment plant.

Swingmill screwpress

High Fibrous Sludge

DSM-702-D Swingmill plate screwpress dewatering papermill sludge.  The new plate configuration of the Swingmill was effective at dewatering the high fibrous sludge without clogging the system.

Swingmill screwpress

Paint Sludge

The paint manufacturer required an upgrade on their existing WWTP with an aim to reduce their sludge level and disposal cost.  2x Swingmill 501-D was installed and achieved a Dried Solids level of 44.44%.  Massievely reduced the client’s sludge disposal costs.

DAF sludge

Lamb Abattoir

The improved DSM-501-D Swingmill with Tubox and ultrasonic sensors was installed to dewater DAF sludge from a lamb abattoir.  It greatly eliminated time and costs for removing the sludge.

CAF Sludge dewatering

Glass Production

A complete Swingmill solution was installed for a glass production site.  It consisted a Swingmill, sludge tank, level sensors, pumps, touchscreen control panel, all with IP66 protection and a Polymore chemical dosing unit.

Swingmill pilot test

Cavitation Air Flotation

The all new DSM-121-S Swingmill including a twin tank polymer make-up system was used to dewater CAF sludge from a glass manufacturer.  The system was easy to setup and it achieved excellent results.

Gut Content Abattoir

The lamb abattoir requires to reduce the volume of DAF sludge and gut contents after slaughtering.  They require a system that can cope with a high level of grease and fat without the fear of clogging.
