SD High-pressure Belt Sludge Deep Dewatering System
A secondary sludge deep dewatering system designed to further reduce sludge cake moisture after conventional mechanical dewatering.
A secondary sludge deep dewatering system designed to further reduce sludge cake moisture after conventional mechanical dewatering.
Product Overview
The SD High-Pressure Belt Sludge Deep Dewatering System is designed for secondary deep dewatering of sludge cake after conventional sludge dewatering equipment.
It is used after belt press, centrifuge or screw press dewatering. For sludge cake with approximately 80% moisture content, the system can further reduce moisture to below 70% or even below 60%, depending on the conditioning agent and sludge characteristics.
The system first modifies the sludge cake by adding conditioning agents. Through efficient mixing, the sludge structure is adjusted and water-holding capacity is reduced. Then the modified sludge enters the high-pressure belt dewatering machine, where progressive pressing and high-pressure roller compression further reduce the sludge moisture.
The basic process flow is:
Primary Dewatered Sludge Cake → Conditioning Agent Dosing → Efficient Mixing → Uniform Feeding → High-Pressure Belt Dewatering → Final Cake Discharge
This product is a professional sewage treatment solution developed for [target sewage types such as municipal domestic sewage/industrial organic wastewater/breeding wastewater/medical wastewater]. Integrating [core technologies such as biological treatment/membrane separation/advanced oxidation/intelligent control], it can efficiently remove pollutants including COD, BOD, ammonia nitrogen, total phosphorus, suspended solids, and toxic and harmful substances from sewage. With core advantages of [small footprint/low operating cost/high treatment efficiency/easy operation and maintenance], the product is widely applicable to [application scenarios such as urban communities, industrial parks, livestock and poultry farms, medical institutions, scenic spots]. The treated effluent can meet [specific standards such as GB18918-2002 Discharge Standard of Pollutants for Municipal Wastewater Treatment Plants (Grade 1A) / local customized discharge standards], realizing harmless discharge or resource recycling of sewage
Core Advantages
- Secondary deep dewatering after belt press, centrifuge or screw press
- Can further reduce sludge cake moisture from around 80% to below 70% or 60%
- Original dewatered sludge does not need dilution before modified mixing and pressing
- Continuous operation, high automation and simple maintenance
- Compact layout, low height and convenient arrangement
- Fully enclosed structure for cleaner operation and better odor control
- Efficient Purification & Compliance Assurance
Adopting [core technology name], it can rapidly decompose complex pollutants in sewage with a pollutant removal rate of up to [specific percentage, e.g., over 95%], ensuring stable compliance of effluent quality and strong adaptability to fluctuations in water quality. - Energy Conservation, Environmental Protection & Cost Control
Designed in line with energy-saving concepts, the equipment/agent [e.g., uses low-power motors/zero chemical addition with biological strains/circulating treatment process], significantly reducing energy consumption and chemical costs during operation. It also minimizes sludge production and lowers solid waste disposal expenses. - Flexible Adaptation & Easy Installation
To meet diverse scenario requirements, it offers [modular assembly/mobile deployment/customized configuration] solutions, occupying only [specific ratio, e.g., 60%] of the area of traditional processes. Whether for new projects or renovation of old facilities, installation and commissioning can be completed quickly. - Intelligent Management & Hassle-Free Operation
Equipped with [intelligent sensors/Internet of Things (IoT) monitoring platform/automatic dosing system], it can real-time monitor water quality indicators and equipment operating status, supporting remote control and fault early warning. No on-site personnel are required, reducing the threshold for manual operation and maintenance. - Green Sustainability & Resource Recycling
The treated effluent can be used for [farmland irrigation/landscaping irrigation/industrial cooling water/municipal miscellaneous use] as needed, realizing water resource recycling. Sludge can be converted into [organic fertilizer raw materials/biomass fuel] after further treatment, aligning with green development concepts.
