Step 1: The dehydrated sludge (about 80% moisture content) and the sludge modifier are mixed quickly and evenly in the sludge modification mixer. Through the action of the modifier, the cell wall is destroyed, the sludge particle structure is changed, the sludge granulation and porosity are increased, and the subsequent dehydration effect is improved.
Step 2: The modified sludge is sent to the continuous sludge deep dewatering machine to achieve sludge dewatering under high pressure and intensive force. According to the theory of filtration and pressing, the thinner the cake, the larger the porosity of the cake, the smaller the filtration resistance, and the better the effect of filtering and pressing. After pressing, the mud cake is only a 5~10mm thin sheet, the sludge water content is reduced to 55%~70% (according to the treatment requirements of the mud cake water content can be adjusted), easy to crush, and the water retention is greatly reduced.
Step 3: After dehydration, the fine particles inside the sludge increased, the water was removed, the pores were reduced, and the sludge appeared fluffy, which was convenient for subsequent treatment.

Sludge Dewatering Equipment industry knowledge

Through innovative industrial design, the sludge deep dehydration equipment has broken through the limits of traditional dehydration technology and upgraded sludge disposal from simple reduction treatment to the dimension of resource utilization. Through the synergistic effect of multi-level mechanics and chemistry, the equipment realizes the efficient conversion of sludge from colloidal state to solid products, laying a key foundation for downstream links such as incineration power generation and building materials preparation.

Its technological innovation is reflected in the precise coordination of each link. The sludge deep dehydration equipment mixes the dehydrated sludge and sludge modifier evenly in the sludge modification mixer. Through the action of the modifier, the cell wall is destroyed, the sludge particle structure is changed, the sludge particle size and porosity are increased, and the subsequent dehydration effect is improved. The modified sludge is sent to the continuous sludge deep dehydrator to achieve sludge dehydration under high pressure and strong force. The continuous pressing technology is adopted in the deep dehydration stage. The equipment constructs a dynamic boosting field through the synergistic effect of the tapered filter chamber and the intelligent back pressure system.

The sludge deep dehydration equipment realizes a fully enclosed design, which is convenient for gas collection. It occupies a small area and can be installed on the ground. It is generally arranged in the free space of the original primary dewatering sludge yard. The product is highly safe and has no high-pressure pipes, valves or other external force release devices.

With the advancement of the construction of "zero-waste cities", this type of equipment is upgrading from a single processing unit to a systematic solution, providing innovative momentum for environmental governance and circular economy.
