Core requirements:For the treatment of municipal sludge, industrial wastewater sludge, and desulfurization gypsum, it is required that the equipment integrates concentration and dehydration functions (reduction), low filter cake moisture content (15% -20%), and meets environmental emission or building material utilization standards..

1. Municipal sludge treatment
Typical materials:Municipal sludge (moisture content>95%, high viscosity organic matter).
Core pain point:Traditional concentration has low efficiency and requires rapid reduction of moisture content to reduce volume..

Solution:
Main equipment: DNY type concentration and dehydration integrated machine. Adaptation design: The inclined plate concentration zone rapidly increases sludge concentration (from 3% to 35%), and the vacuum pre dehydration zone removes free water (reducing moisture content to below 60%); Processing capacity 5-20m³ /h， Reduce the floor area by 60%, suitable for the expansion of small and medium-sized sewage treatment plants.

2. Dehydration of desulfurization calcium sulfate (gypsum)

Typical materials:desulfurization gypsum (fine particles, -200 mesh, accounting for more than 90%, requiring low moisture content for building materials).

Solution:
Main equipment: DNY type concentration and dehydration integrated machine (pre concentration)+DZY type belt press vacuum filter (deep dehydration). Adaptation design: The concentration section avoids fine particle agglomeration, while the dehydration section gradually removes capillary water through multi-stage vacuum suction and inclined filter belt; The final moisture content of gypsum is 12%, which can be directly used for the production of cement retarders.
