MUNICIPAL & INDUSTRIAL WASTEWATER
Sludge Dewatering Equipment
Select a screw press or mobile dewatering system around your sludge flow, feed solids and target cake solids. Specify polymer preparation, screening or flotation equipment where the process calls for it.
APPLICATIONS
Start with your sludge and site constraints
The same feed flow can carry very different solids loads. Sludge source, peak flow and feed solids help define the duty before you compare equipment.
Municipal wastewater plants
Plan for changing feed solids, daily operating hours, filtrate return and how cake will be moved off site.
Evaluate screw presses ↗Industrial wastewater plants
For food, beverage or other industrial streams, identify whether the feed is DAF float, chemical sludge or biological sludge. Include grease and any available sample data.
Explore flotation equipment ↗EPCs and plant upgrades
Check equipment footprint, discharge height and utilities against the existing plant. Consider a mobile unit where access, installation time or temporary operation drives the decision.
Evaluate mobile dewatering ↗PROCESS SELECTION
Where each equipment type fits
A common route from incoming wastewater to dewatered cake. Use the stages relevant to your site.
Remove coarse solids
Choose a drum screen around peak flow, opening size and the incoming solids.
Collect floatable material
Where appropriate, use dissolved air flotation to separate suspended solids and grease.
Prepare polymer
Match solution preparation and dosing to the polymer grade and the sludge response.
Produce a sludge cake
Evaluate dry-solids loading, target cake solids and where the filtrate and cake will go.
Disc and tube diffusers supply air to biological treatment basins where aeration is required.

EQUIPMENT AND WORKSHOP
Compare equipment against your project
Sludge Dewatering Systems Co., Ltd.
- Compare SDP models by footprint, operating weight, power and cake discharge height.
- Review fixed or mobile equipment and the supporting stages your application needs.
- Use published reference data for initial screening and review performance against your actual feed.
SIZING INQUIRY
Share your operating data
Start with your sludge source, average and peak flow, feed total solids, operating hours and target cake solids. If this is a retrofit, include the available footprint and discharge height.
BEFORE YOU SPECIFY
Common sizing questions
Why do you need flow and total solids?
Flow defines the hydraulic duty. Feed solids and density let you estimate the dry-solids load the equipment must handle.
Can I choose a model from the reference table?
Use it to shortlist models. Check the sludge source, conditioning response and the required cake solids before fixing the equipment selection.
What should I send for an existing plant upgrade?
Include the current equipment, the operating problem you want to solve, available floor space, connections and cake discharge arrangement.
