01 Why Operators Choose Juntai Screw Press
Every municipal and industrial plant fights the same sludge problem: wet cake that is expensive to haul and hard to dispose of. A screw press that de-waters continuously, without filter cloth or high-speed centrifuges, is the answer - but only if it holds up to fibrous and oily sludge without clogging and without eating into your energy budget.
|
0.3 kW
Ultra-Low Energy
A single 0.3 kW screw drive replaces the high-torque centrifuges and blowers of conventional dewatering, cutting the power cost of every tonne of sludge processed.
|
5 min/day
Minimal Maintenance
No filter cloth to wash or replace - the screw is self-cleaning. Routine maintenance takes about 5 minutes a day, keeping operators free for real work.
|
SUS304
Stainless Build
Dewatering body, dosing tank and flocculation mixing tank are all SUS304 stainless steel, giving long-term corrosion resistance in aggressive sludge environments.
|
L2600 mm
Compact Footprint
A single skid only 2600 mm long fits into confined plant rooms and small dewatering stations, cutting installation and infrastructure cost.

03 Screw Press vs Conventional Dewatering
The table below compares dewatering technologies on the factors that drive operating cost and reliability. Juntai screw press dewatering delivers a dry, adjustable cake at a fraction of the energy of a centrifuge - with no filter cloth and no pressurized operation.

04 NH-251 Screw Press - Machine & Configuration
The NH-251 is the standard screw press build. Its SUS304 construction, six interface ports and continuous screw-pressure dewatering are detailed below.
05 Application Scenarios
|
Municipal Wastewater Treatment Plants
Dewatering primary, secondary and mixed sludge from the settling and biological stages, producing a stackable cake ready for landfill or incineration.
Food & Beverage Processing
Separating and concentrating organic sludge and by-products - including fruit, vegetable and dairy waste - where high-viscosity solids clog other machines.
Pulp & Paper Mills
Reducing moisture in pulp and paper sludge before disposal or reuse, cutting haulage volume and improving energy recovery.
Industrial Sludge Management
On-site dewatering for factories and STPs that want to cut sludge volume, lower disposal cost and meet eco-friendly discharge targets.
