Lower volume & cost
Dewatering with screw, belt-filter and centrifuge presses sharply reduces moisture, mass and disposal cost.
Technology · Sludge
Sludge management — less volume, lower cost, recovered energy.
Better wastewater treatment means more sludge. Glorinda cuts its volume and recovers value through dewatering, drying, incineration and thermal hydrolysis (THP) — turning a disposal liability into biogas, compost or fuel.

What problem does it solve?
From the plant floor, in your words
Sludge is often the hidden cost of a good treatment plant. These are the problems that bring clients to us.

Benefits
What you get
More biogas with THP
Thermal hydrolysis raises digestibility, increases biogas yield and produces hygienic digested sludge.
Energy & compost
High-quality biogas and organic compost from municipal sludge, animal excreta and agricultural waste.
Cleaner operation
Drying and incineration reduce pollution risk near urban and residential areas.
Fits the moisture curve
We select mechanical dewatering, thermal drying or incineration to hit the target moisture content.
Integrates with the plant
Sludge handling is engineered as part of the water plant, not bolted on afterwards.
How it works
The process, stage by stage
We match the technology to the moisture-content target: mechanical dewatering first, then thermal drying or incineration where required, with THP to unlock biogas.
- 01
Thickening
Reduce water content ahead of dewatering to cut downstream load.
- 02
Dewatering
Screw presses, belt-filter presses and centrifuges remove the bulk of the water mechanically.
- 03
Thermal hydrolysis (THP)
High-temperature steam raises digestibility, boosts biogas and hygienises the sludge.
- 04
Anaerobic digestion
Digest the conditioned sludge to produce biogas for on-site energy.
- 05
Drying & incineration
Finish moisture removal and, where needed, incinerate for volume reduction and energy recovery.
Engineering detail
Reading the moisture curve
Sludge treatment technology is chosen against a single continuum: how much water has to come out, and how expensive each successive percentage point becomes. Mechanical dewatering is cheap and gets you a long way. Thermal drying is expensive and takes you further. Incineration removes what remains.
The engineering judgement is knowing where to stop. Screw presses, decanter centrifuges, filter presses and belt filter presses handle the mechanical stage and, for many plants, produce a cake dry enough that haulage and disposal cost falls sharply without any thermal step at all. Pushing further only pays where disposal is constrained, where the material has value as fuel or compost, or where volume reduction is the binding limit.
Thermal hydrolysis changes the calculation upstream of all of this. Passing high-temperature steam through the sludge increases its digestibility, so anaerobic digestion converts more of the organic content and produces more biogas — and the sludge leaving the digester is hygienic. The volume that has to be dewatered at all is smaller, and part of the treatment cost is offset by the energy recovered.
That matters most where a plant sits near residential areas. Sludge accumulation is an inherent consequence of treating wastewater well — the better the treatment, the more sludge is produced — and when a works is close to housing, that accumulation becomes an odour and pollution problem rather than merely a cost. THP followed by digestion addresses both at once, producing high-quality biogas and organic compost from residual municipal sludge, animal excreta and agricultural waste.

FAQ
Answers for engineers and procurement
Why does better treatment create more sludge?
The more thoroughly you remove contaminants from water, the more of them end up concentrated in the sludge. That is why sludge handling has to be engineered alongside the water plant, not after it.
What is thermal hydrolysis (THP)?
THP passes high-temperature steam through the sludge to raise its digestibility. The result is more biogas from anaerobic digestion, a smaller residual volume and hygienic output.
Which dewatering equipment do you use?
Screw presses, belt-filter presses and decanter centrifuges, selected for the sludge type and the target cake dryness.
Can sludge become a useful product?
Yes — high-quality biogas, organic compost and, where suitable, incineration fuel can be produced from municipal, industrial and agricultural sludge.
Do you integrate sludge handling with the water plant?
Yes. Sludge dewatering, drying, THP and incineration are engineered as part of the overall water and wastewater package.
