TNW Co., Ltd: Screw Press for Solid-Liquid Separation | Your Reliable Premium Manufacturer

TNW Co., Ltd: screw press for Solid-Liquid Separation | Your Reliable Premium Manufacturer

In the field of wastewater treatment and sludge disposal, the screw press sludge dewatering machine has become a mainstream solid-liquid separation equipment, thanks to its small footprint, low energy consumption, anti-clogging performance and fully automatic operation. However, the market is flooded with numerous screw press manufacturers. Many cut corners on materials, falsify technical parameters and offer inadequate after-sales service, leaving buyers struggling with various issues.

As a professional premium manufacturer of screw presses for solid-liquid separation, TNW Environmental Protection has been deeply engaged in the environmental protection equipment manufacturing industry for more than a decade. We adhere to exquisite craftsmanship and sincere service. With reliable product quality and abundant practical project cases, we have won recognition from clients across municipal engineering, industrial production, livestock breeding and many other sectors.

Focused on R&D and Manufacturing of Screw Presses, Guaranteed Quality from the Source

TNW Environmental Protection is a professional original manufacturer of screw presses. We own a standardized production workshop covering 12,000 square meters, a full set of precision processing equipment and a professional technical R&D team. The whole workflow including R&D and design, plate cutting, precision welding, assembly and factory commissioning is fully controlled in-house. We never do OEM production, so the quality of every screw press is well guaranteed from the very beginning.

Unlike small manufacturers that adopt ordinary carbon steel and inferior accessories, we use premium materials for all core components. The main body is made of 304 or 316 stainless steel, featuring excellent corrosion resistance and wear resistance, which makes the equipment adaptable to complex working conditions with acid, alkali and oily substances. The screw shaft is hard chrome plated for higher hardness and longer service life. The fixed rings and moving rings are stamped with precision molds to ensure uniform fitting gaps and outstanding self-cleaning effect. All supporting motors and electrical control components are supplied by well-known brands such as Siemens and Schneider, delivering stable operation and low failure rate.

Our self-developed TNW series screw presses are clearly classified by model, ranging from small TNW101 units to large TNW502 models. The processing capacity covers 0.5 to 50 cubic meters per hour, fully meeting the solid-liquid separation demands of projects of different scales in municipal wastewater treatment, food processing, papermaking and printing & dyeing, chemical and leather industries, livestock breeding and other fields.

Core Advantages of Screw Press: Efficient Solid-Liquid Separation for Higher Cost Savings

As key equipment for solid-liquid separation, TNW screw presses outperform traditional plate and frame filter presses and centrifuges, effectively solving common industry pain points.

1. High-efficiency Dewatering for Complete Solid-Liquid Separation

Adopting an integrated thickening and dewatering design, the front thickening section rapidly adjusts sludge concentration, while the rear dewatering section squeezes sludge via the screw shaft. The moisture content of sludge can be reduced from 95%-99% down to 75%-85%, which greatly cuts sludge volume and facilitates subsequent transportation and disposal. The filtrate is clear enough for direct standard discharge or reuse, realizing sludge reduction and thorough mud-water separation.

2. Anti-clogging with Self-cleaning Function for Complex Sludge Treatment

With the unique stacked structure of alternating fixed rings and moving rings, the rotating screw shaft drives moving rings to move dynamically and continuously cleans the filter gaps. The equipment requires no high-pressure water flushing and never gets clogged. It works perfectly for oily, high-viscosity and fiber-containing sludge, enabling 24-hour non-stop operation.

3. Low Energy Consumption to Cut Long-term Operating Costs

The screw shaft runs at a low speed of 2 to 3 revolutions per minute. Its power consumption is only one-fifth of that of centrifuges, with energy consumption as low as 0.3-0.5 kWh per ton of sludge. It needs little flushing water and less flocculant dosage. Compared with traditional equipment, it reduces overall operating costs by more than 40% in the long run.

4. Compact Structure for Flexible Installation

The integrated design combines electric control cabinet, flocculation mixing tank and dewatering main unit. It only takes 1/2 to 1/3 of the floor space required by conventional equipment. No large-scale civil engineering is needed, and the whole installation and commissioning can be completed within 3 days. The screw press can be installed indoors, outdoors or on skids, which is ideal for renovation projects and small-scale stations with limited space.

5. Fully Automatic Operation with Easy Maintenance

Equipped with a PLC intelligent control system, the machine can be linked with dosing pumps and sludge feed pumps to realize automatic feeding, dewatering, discharging and fault alarm. It supports unattended operation all day long. Daily maintenance is simple, and only regular lubrication inspection is needed, which greatly saves labor costs.

Wide Application: Screw Presses for Various Industries

Thanks to strong adaptability, TNW screw presses have been widely applied in multiple industries, with proven solid-liquid separation performance.

Municipal wastewater treatment: Treat excess activated sludge and sludge from pipeline dredging, suitable for small sewage stations and large sewage plant renovation projects.

Food processing: Handle high-oil and high-viscosity organic sludge generated from meat and fruit & vegetable processing.

Papermaking and printing & dyeing: Efficiently separate high-fiber and high-chroma sludge, and the dewatered sludge cake can be recycled.

Chemical and leather industries: Adapt to complex industrial sludge containing acid, alkali and heavy metals. Corrosion-resistant materials ensure stable long-term operation.

Livestock breeding: Treat manure wastewater from pig farms and poultry farms. The dewatered sludge cake can be processed into organic fertilizer to realize resource recycling.
