Description

Mobile Skid-Mounted sludge dewatering system

1.Product Overview

The DAGYEE Mobile Skid-Mounted Sludge Dewatering System is a pre-assembled, fully integrated dewatering solution designed for rapid deployment and temporary applications. Mounted on a rugged steel skid, this system includes all necessary components—flocculation tank, screw press dewatering unit, control panel, and associated piping—in a single transportable package. It offers the flexibility to move between sites and handle varying sludge loads.

2. Working Principle

The system operates on the same proven screw press dewatering principle, with flocculated sludge entering the thickening zone where free water drains through the ring gaps. The sludge then moves to the dewatering zone where increasing pressure squeezes out remaining water. The main difference is that all components are integrated onto a single skid, allowing for fast setup and relocation.

The integrated design includes:

• Screw press dewatering unit

• Flocculation tank with sludge mixer

• Support frame and water outlet tank

• Electrical control panel

• Optional odor elimination system

3.Technical Advantages

• Rapid Installation — Eliminates lengthy on-site construction

• Cost Effective for Temporary Projects — No permanent facility investment required

• Easy Relocation — Can be moved between sites as project demands change

• Minimal Civil Works — No special foundations or concrete pads needed

• Low Operation Cost — Same energy and water savings as stationary units

• Fully Automatic — PLC-controlled with touch screen interface

Note: Capacity and cake dryness depend on sludge characteristics, polymer type, and dosage. A sludge test is recommended for accurate sizing.

Materials:

• Screw and rings – Stainless 304 (316L available for corrosive stuff)

• Housing – Stainless 304

• Frame – Carbon steel with epoxy coating

Cake solids: 15% to 30% depending on your sludge and chemical

Temperature range: 0°C to 60°C

Voltage: We match yours – 380V/50Hz, 460V/60Hz, or others

5. Comparison with Traditional Equipment

Each technology has appropriate applications. The selection depends on specific site requirements including sludge characteristics, available labor, energy costs, and budget constraints.

What this means for you:

• Want the driest cake possible? Get a centrifuge. But budget for power and repairs.

• Have almost no budget upfront? Get a belt press. But plan for labor and water.

• Want the lowest total cost and least headache? Get our screw press.

6. Selection & Maintenance

Selection Worksheet

To select the appropriate model, calculate your dry solids production rate.

Step 1: Measure or estimate your sludge flow rate in cubic meters per hour.

Step 2: Measure your inlet solids concentration in percent or grams per liter. One percent solids equals ten grams per liter.

Step 3: Calculate dry solids per hour: Flow rate × Solids concentration × 10 (for grams per liter to kilograms per hour).

Step 4: Multiply by 1.5 to provide margin for variations.

Step 5: Select a model with dry solids capacity exceeding this number.

Example Calculation

Sludge flow: 8 cubic meters per hour
Inlet solids: 2 percent (20 grams per liter)
Dry solids: 8 × 20 = 160 kilograms per hour
With margin: 160 × 1.5 = 240 kilograms per hour
Recommended model: DAG-301 or DAG-302 depending on flow characteristics

Free Laboratory Testing

DAGYEE maintains a pilot-scale test unit for customer sludge samples. The test procedure requires approximately five liters of representative sludge.

The test report includes:

• Achievable cake solids content

• Recommended polymer type and dosage

• Filtrate quality measurements

• Recommended model based on test results

There is no charge for this service. Shipping costs for the sample are the responsibility of the customer.

Maintenance Planning

The maintenance program for this equipment is substantially simpler than for belt presses or centrifuges.

Daily Tasks (Five Minutes)

• Visual check for any external leaks

• Listen for changes in operating sound

• Verify control panel shows normal status

Monthly Tasks (Thirty Minutes)

• Check gearbox oil level through sight glass

• Apply grease to motor bearings if equipped with fittings

• Inspect discharge area for abnormal buildup

Quarterly Tasks (One Hour)

• Check all accessible fasteners for tightness

• Clean any debris from around the machine

• Verify wash system operation

Annual Tasks (Two to Four Hours)

• Drain and replace gearbox oil

• Remove and inspect a sample of rings for wear measurement

• Check shaft seals for signs of leakage

• Inspect electrical connections in control panel

7.Applications

• Emergency response and disaster relief

• Construction and excavation sites

• Temporary wastewater treatment facilities

• Pilot projects and technology testing

• Seasonal operations (agricultural processing)

• Remote sites without permanent infrastructure

• Municipal bypass and overflow treatment

• Industrial plant maintenance shutdowns

Ideal for: Projects requiring fast deployment, temporary operation, or frequent relocation—the mobile skid-mounted system delivers professional-grade dewatering performance without the commitment of a permanent installation.
