Glorinda’s services
Sludge management:
dewatering, drying and incineration
At Glorinda, we design and deliver sludge management systems that dewater and dry municipal and industrial sludge, reducing its volume and moisture content to lower disposal cost.
Sludge management:
Dewatering, Drying and Incineration
Sludge accumulation is one of the main challenges in wastewater treatment plants, with an important consequence: the more effectively wastewater is treated, the more sludge can be generated. For treatment plants near urban and residential areas, sludge can create significant environmental and commercial challenges.
A key point is that a tanker leaving your site is mostly carrying water. Increasing cake solids through dewatering, followed by drying, reduces the mass you need to transport. Incineration can eliminate the remaining sludge while recovering energy.
Your solution can be on-site H₂O₂ and AOP.
“Sludge disposal costs more every single year”.
What problem does it solve?
Glorinda provides efficient and reliable sludge management solutions for industrial and municipal processes, including dewatering, drying, and incineration.
Benefits
Volume is the whole game
Moisture content falls at every stage; dewatering by mechanical processes, then drying by mechanical or thermal methods, then incineration. Each step removes mass you would otherwise transport.
Four dewatering routes
Screw presses, centrifuges, filter presses and belt filter presses. Which one suits depends on the sludge, not on which is most common.
Thermal hydrolysis raises biogas yield
Passing high-temperature water vapour through the sludge increases its digestibility, which produces a hygienic sludge output from the anaerobic digester and more biogas from the improved digestion.
Residue with a use
Thermal hydrolysis makes it possible to produce high-quality biogas and organic compost from a wide range of organic wastes and scraps; residual municipal sludge, animal excreta and agricultural waste.
Incineration where it pays
Where drying alone is not enough, incineration with energy recovery closes the line; with bottom-ash handling and flue gas treatment designed in.
Fewer odour complaints
A hygienic, stabilized, low-moisture output is a much smaller nuisance problem than wet sludge sitting in a holding tank.
How it works
The sludge line runs in one direction: reduce moisture, stabilise, and then either recover value or dispose of a much smaller mass. Moisture content falls from around 100 towards zero as the sludge moves through dewatering, drying and incineration.
Which equipment sits at each stage depends on the sludge itself — municipal primary and biological sludge behaves nothing like oily refinery sludge, mineral sludge from mining, or the coloured chemical sludge from a textile effluent plant.
01
Dewatering (mechanical processes)
The largest single reduction in mass, achieved by screw presses, centrifuges and filter presses, or belt filter presses. Selection depends on the sludge characteristics, the cake dryness required downstream, polymer consumption and how much operator attention the site can give it.
02
Thermal hydrolysis and digestion
Where the objective is biogas, thermal hydrolysis comes before digestion. High-temperature water vapour passing through the sludge increases its digestibility, producing a hygienic sludge output from the anaerobic capacitor and more biogas from the improved digestion. It significantly increases the efficiency of the anaerobic digestion process and reduces residual sludge volume and pollution.
03
Drying (mechanical and thermal methods)
Further moisture removal, either mechanically or by thermal drying. This is the stage that determines whether the residue can be incinerated, composted or used as a fuel — and Glorinda supplies the dryers as well as designing the line.
04
Incineration
The end of the line where no material route exists. Organic waste is burned and converted into incinerator bottom ash, treated flue gas and particles cleaned before release, and heat energy available for recovery.

Typical applications
- Reducing haulage volume and disposal cost
- Producing a cake dry enough to incinerate
- Increasing biogas yield from an existing digester
- Removing odour nuisance from a plant near housing
- Producing organic compost from residual sludge, animal excreta and agricultural waste
- Hygienising sludge before land application
- Debottlenecking a dewatering stage that limits plant throughput
which sludge management system suits your needs?
Selecting an efficient sludge management system is an engineering decision, not a purchasing one. We run feasibility and pre-feasibility studies, characterise the stream, compare the routes on capital and operating cost, and act as owner’s engineer while somebody else builds it if that suits you better.

Frequently asked questions
Screw presses, centrifuges, filter presses and belt filter presses all have a place. Centrifuges give high throughput in a small footprint and cost more to run; belt filter presses are simpler and need more space and washwater; filter presses reach the highest cake dryness in batch operation; screw presses are the lowest-energy and lowest-attention option. Sludge characteristics and required cake dryness decide it.
It increases digestibility, which produces more biogas from improved digestion and a hygienic sludge output from the digester, and it reduces residual sludge volume and pollution. The size of the improvement depends on your sludge, so we would want to see digester performance data before quantifying it for your plant.
Yes. Thermal hydrolysis makes it possible to produce high-quality biogas and organic compost from a wide range of organic wastes and scraps, including residual sludge from municipal wastewater treatment, animal excreta and agricultural waste.
No, it is the endpoint where no material route exists. Composting, land application after hygienisation, and use as a fuel are all better outcomes where the sludge allows. Incineration is chosen when contamination rules those out or when the site can use the recovered heat.
Usually. Dewatering is frequently the bottleneck on an otherwise adequate plant, and replacing or adding a stage is far less disruptive than a rebuild. We would start by measuring what your current line actually achieves rather than what it was specified to achieve.
