4x2 Sewage Suction and Purification Truck

Proven 4×2 Sewage Suction and Purification Truck with Dongfeng Chassis

The 4x2 Sewage Suction and Purification Truck is a mobile, all-in-one sewage treatment vehicle built on the Dongfeng Duolika D7 chassis. It sucks sewage and sludge directly from septic tanks, grease traps, and other sources, separates large debris, adds flocculant automatically, and dewaters with a twin screw press. The output is dry sludge cake and treated water, handled on site, with no wet sludge left on the ground. Compared with a traditional vacuum tanker, this Sewage Suction and Purification Vehicle is not limited by tank volume. Sewage Suction and Purification Truck can work continuously for 24 hours in one spot, which greatly reduces transport trips, labor, and secondary pollution. The sludge cake reaches about 80% moisture content, and the treated water meets the third-level discharge standard for municipal sewer networks. Choose this 4x2 Sewage Suction and Purification Truck for a reliable, flexible, export-ready solution that reduces sludge volume, transport costs, and secondary pollution.

FEATURES

Dongfeng Chassis for Reliable Durability

This 4×2 Sewage Suction and Purification Truck uses the Dongfeng Duolika D7 chassis with a 3800 mm wheelbase, a Yuchai 170 HP engine, and an 8-speed transmission. It provides stable power, good maneuverability on urban and rural roads, and easy maintenance.

11 KW Vacuum System for Direct Septic Tank Sewage Suction Truck Operation

A powerful 11 KW vacuum system lets this septic tank sewage suction truck pull material straight from septic tanks, grease traps, and other waste sources, with no extra pumping equipment.

Patented Cutter-Type Separator for Complex Sewage Conditions

Before dewatering, the patented cutter-type solid separator removes plastic bags, branches, stones, and other large debris. This protects the equipment and keeps the Sewage Suction and Purification Vehicle running smoothly on difficult jobs.

Automatic Dosing and 402 Twin Screw Press for a Screw Press Sewage Treatment Truck

After automatic flocculant dosing, the sludge enters the 402 dual-spindle twin screw press. The self-cleaning, anti-clogging screw plates deliver high throughput and produce dry sludge cake at about 80% moisture content. This makes 4×2 Sewage Suction and Purification Truck for demanding conditions.

24-Hour Continuous Sewage Suction Truck with Dewatering Performance

Connect to 380V external power or use the onboard 50 KW generator. Low-speed operation keeps noise, vibration, and energy use low. This Sewage Suction Truck with Dewatering can work in place around the clock, unlimited by tank capacity.

Zero-Leakage Design for Cleaner On-site Sewage Treatment

Sludge never touches the ground, which prevents dripping during transfer and secondary pollution. The sludge cake can also be reused as organic fertilizer raw material, supporting reduction and harmless treatment.
