Papermaking sludge enhancer is a compound chemical additive specially designed to optimize the papermaking sludge treatment process. Its core advantages and characteristics are as follows:
One dose with multiple effects, simplifying the process
Function integration: Integrating multiple functions such as flocculation, conditioning, and pH adjustment, it replaces traditional chemicals that need to be added step by step, such as polyacrylamide (PAM), lime, and ferrous sulfate, reducing operation steps.
Wide applicability: It is suitable for various types of papermaking sludge (such as deinking sludge and black liquor sludge from pulp making), and there is no need to adjust the chemical formula for different types of sludge.
Two. Enhance processing efficiency
Dewatering optimization: Through charge neutralization and bridging effects, the flocculation of sludge particles is accelerated, the specific resistance of sludge is reduced, and the efficiency of plate and frame filter press or centrifugal dewatering is increased by 30% to 50%, with the moisture content reduced to below 50%.
Significant reduction: The volume of sludge is reduced by 40% to 60%, lowering subsequent disposal costs (such as transportation, incineration or landfill expenses).
Three. It combines environmental protection and economy
Reduce chemical residues: There are no heavy metals or persistent organic pollutants. The treated sludge meets the requirements of the "Sludge Disposal Standard for Municipal Wastewater Treatment Plants" (GB/T 23484) and can be directly used as raw materials for building materials or for land improvement.
Comprehensive cost savings: Although the unit price may be higher than that of a single agent, the overall treatment cost can be reduced by 15% to 25% due to the reduction in agent types (saving 20% to 30% of agent costs), labor and equipment energy consumption.
Four. Easy to operate and highly compatible
Ready-to-use: No pre-dissolution or complex equipment is required. It can be directly added to the sludge tank or the feed end of the dewatering equipment in proportion (usually 0.5%-2% of the dry sludge volume).Process compatibility: Applicable to existing equipment such as filter presses and belt presses, without the need to modify the production line.
Example of application scenarios
Small and medium-sized paper mills: Address the issues of limited space for sludge treatment and high labor costs, achieving "one-agent treatment + rapid dewatering".Environmental protection strictly managed area: Meet the environmental protection standards for sludge disposal and avoid the risk of exceeding standards due to the problem of multi-agent coordination.
Precautions
Dosage optimization: It is recommended to determine the optimal dosage through small-scale tests. Excessive dosage may cause a rebound in sludge viscosity.
Equipment maintenance: Regularly clean the filter cloth of the dehydration equipment to prevent clogging by the residue of the enhancer.
Summary: This sludge efficiency enhancer achieves an "additive" effect (improving efficiency and environmental protection) through a "subtraction" design (reducing the types of chemicals and operation steps), making it an ideal solution for papermaking enterprises to reduce costs, increase efficiency, and simplify sludge management.
