Sludge Dehydrator Description

Screw press sludge dewatering machine is an efficient and reliable solution to sludge water management and wastewater treatment. It utilizes a screw mechanism to transport and compress sludge, separating the water from the solid materials. The dewatered sludge cake is with reduced moisture content and volume, making it easier to handle and dispose of. Dagyee is a trusted manufacturer of sludge dewatering screw press, providing customization options to meet specific demands. Our machine also serves wastewater treatment, food proccessing industry, etc.

Sludge Dehydrator Process

The dehydrator is mainly composed of sludge premix module, concentration and dewatering module and electric control system. In the actual working process, the sludge is pumped to the metering tank by an external conveying pump. The sludge after distillation further flows into the flocculation tank, reacts with the flocculant fully under the stirring of the agitator to produce stable alum, and then enters the dewatering screw through the upper part of the flocculation tank. In the dehydrated body, alum flowers concentrate in the concentrated section by gravity and advance to the dehydrated section at the same time. In the process of propulsion, with the filter clearance and pitch gradually reduced, and the back pressure plate blocking effect.

The main body of the screw press dehydrator is a filter device which is superimposed by a plurality of fixed rings and floating rings, and the screw shaft runs through it. The anterior segment is concentrated and the posterior segment is dehydrated. Sludge concentration and dewatering are done in one cylinder. During the spiral rotation, the floating ring and the fixed ring will form a dislocation movement, and the water will be discharged from the gap between the floating ring and the fixed ring. It replaces the traditional filter cloth filtering method with a unique and subtle filter pattern.

Following the principles of force and water in the same direction, thin layer dehydration, appropriate pressure, and prolonged dehydration path, the screw press solves the problems of easy blockage, inability to handle low-concentration sludge and oily sludge, high energy consumption, and complex operation. The dehydration goal of high efficiency and energy saving was achieved.

Sludge Dehydrator Advantages

Waste volume reduction
The focus of sludge dewatering is to reduce weight and volume in order to minimize waste disposal costs. Therefore water removal is the primary means of volume reduction until the sludge by-products can be economically disposed of.

Reduce transportation costs
A dry, high solids content cake means lower costs. The use of dewatering equipment is an effective tool for managing sludge accumulation and can reduce transportation costs and storage costs.

Wastewater recycling
Once the sludge is dewatered and treated water is free of hazards and contaminants, it can be recycled by industry and communities for reuse. For example, steam power plants use reclaimed water to provide power services to communities.

Automation
Many people think of filter presses as labor-intensive equipment. In fact sludge dewatering filter presses can be automated with automatic cloth washers, mechanically assisted cake release devices and sophisticated control systems that allow communication with the main plant control system.

Protecting the environment
Reduces the volume of waste to a more compact and manageable size for disposal. While the dry cake is disposed of, the reuse of the filtrate reduces the need for new water sources required for treatment in municipal and industrial wastewater plants, as well as the overall amount of water required for treatment.

Sludge Dehydrator Features
