Pharmaceutical plants, specializing in traditional medicine, generate substantial wastewater, sludge, and residues requiring solid-liquid separation. Compared to other mechanical dewatering equipment like plate and frame filter presses, belt filter presses, and centrifuges, the Screw Press offers superior performance in pharmaceutical sludge treatment. The filtered liquid from the Screw Press is clear, with low cake moisture content, meeting reduction and stabilization requirements, thus reducing energy consumption for subsequent drying and incineration.
As pharmaceutical wastewater emerges as a significant environmental pollutant, including antibiotics, synthetic drug production, and formulation washings, its treatment involves biological, chemical, and physical processes, inevitably yielding large amounts of sludge. This sludge, complex in composition, high in organic content, and toxic, poses challenges for disposal, typically necessitating incineration. Therefore, reducing sludge moisture content early in dewatering is crucial to minimize operational costs and prevent secondary pollution during the dewatering process.
Given these challenges, the Screw Press stands out in pharmaceutical sludge treatment due to its ability to effectively handle high organic concentrations, resulting in a 5%-10% increase in dewatering rates, thus reducing energy consumption for subsequent drying. Constructed from stainless steel for enhanced durability and corrosion resistance, the Screw Press’s screw shaft surface is treated with a wear-resistant coating, ensuring longevity.
With high automation, the Screw Press eliminates manual cleaning between cycles, achieving effective separation of personnel and sludge. Its non-clogging design eliminates the need for high-pressure water jets, preventing secondary pollution and maintaining overall cleanliness in the sludge dewatering workshop. Moreover, the Screw Press can operate unmanned throughout the entire process, from sludge feeding to dewatering, requiring no manual intervention.
