During the sludge treatment process, changes in pH value may affect the stability of the sludge and the subsequent disposal effect. Traditional sludge conditioners (such as lime, iron salts, etc.) can improve the dewatering performance, but they often cause a significant increase or decrease in the pH value of the sludge, thereby affecting its subsequent utilization or landfill. However, sludge enhancers, as a new type of conditioner, not only significantly improve the dewatering efficiency but also maintain the pH value of the sludge stable, making them the preferred solution in current sludge treatment.
The core advantage of the sludge enhancer is that it does not alter the pH value of the sludge.
Sludge enhancer is a modified polymer product with mild chemical properties. After reacting with the solid substances in the sludge, it does not significantly affect the pH value. This characteristic makes it suitable for handling scenarios that are sensitive to pH values, such as biological sludge or chemical sludge.
High-efficiency dehydration performance
The sludge enhancer can quickly react with the solid substances in the sludge to form stable flocs, thereby increasing the filtration speed and the compactness of the sludge cake.
When used in a plate and frame filter press, the sludge cake has a thick thickness, a low moisture content, and uniform dryness both inside and outside, without the "soft center" phenomenon.
Environmental Protection and Economic Efficiency
Compared with traditional conditioning agents, the dosage of sludge enhancer is lower, which can reduce the cost of solid waste treatment.
The filtrate contains very little residual substances and has a fast sedimentation rate, thus not imposing any additional burden on the subsequent water treatment system.
Practical Application Case
Take a municipal sludge treatment project as an example. After using Shijun SJC-08 sludge enhancer:
Improvement in dehydration efficiency: The moisture content of the sludge has decreased from 80% to below 60%.
PH value stability: The pH value of the sludge remained between 6.5 and 7.5 before and after treatment, with no significant changes.
Cost savings: The dosage of the medicine has been reduced by 30%, and the overall processing cost has decreased by 20%.
The traditional lime, iron salts and aluminum salts not only have high costs for the agents themselves, but also have high indirect costs due to the large dosage, increased sludge volume, equipment damage, etc. However, the sludge enhancer has a lower dosage of the agent. According to relevant process experiments, its dosage is only 3-4%, and the generated cost is only about 40% of that of the traditional agents, which can significantly reduce the treatment cost.
Furthermore, the sludge enhancer does not corrode equipment like lime does, nor does it clog the filter cloth like iron salts or aluminum salts do. This is beneficial for protecting the dewatering equipment, reducing the frequency of equipment maintenance and replacement, and improving the working efficiency of the equipment. At the same time, it does not have any adverse effects on the subsequent treatment of the sludge. Instead, it creates favorable conditions for the resource utilization of the sludge, such as incineration, brick-making, and composting.
The sludge enhancer is applicable for the dewatering treatment of sludge from various industries such as daily life, printing and dyeing, papermaking, electroplating, chemical industry, leather processing, etc. In the treatment of urban sludge, it can also play an important role, replacing traditional chemicals like lime, iron salts, and aluminum salts, and solving the problems of strong affinity between urban sludge and water and the difficulty in dewatering, achieving deep dewatering.
The sludge enhancer, with its unique mechanism of action, excellent dewatering performance, low cost, and friendliness towards equipment and subsequent treatment, has successfully replaced traditional chemicals such as lime, iron salts, and aluminum salts. It provides an efficient, economical, and environmentally friendly solution for deep sludge dewatering, promoting the progress and development of the sludge treatment industry.
The sludge enhancer achieves efficient dewatering and cost savings without altering the pH value of the sludge. It represents a significant breakthrough in current sludge treatment technologies. In the future, as environmental protection requirements become increasingly strict, this highly efficient and environmentally friendly conditioner will be widely applied in more fields.
