Sludge enhancers play a crucial role in sludge dewatering and are divided into two methods: natural drying and mechanical dewatering. In China, mechanical dewatering is mainly adopted. Sludge dewatering is carried out through equipment such as filter presses, and sludge enhancers are used to enhance dewatering efficiency and reduce the moisture content of sludge.
It is crucial to select the appropriate sludge enhancer for sludge with different characteristics. Effective sludge enhancers can significantly reduce the moisture content of sludge and enhance the dewatering efficiency.
Sludge enhancer is a kind of chemical agent that can change the surface structure of sludge, reduce the solid surface load and specific surface area of sludge, and destroy the structure of bacteria. Its main components include inorganic compounds, sludge surface structure modifiers, degreasing agents, cell wall disruptors, etc. This conditioner has the following advantages:
Reduce the moisture content of the sludge cake to 40%-60% to achieve deep dewatering of sludge.
When used in conjunction with plate and frame filter presses, it can increase the sludge pressing efficiency by 100% to 500% and shorten the sludge pressing cycle.
3. Do not cause corrosion to the equipment.
4. Small addition amount, no need to add lime.
5. Organic and non-toxic, it is suitable for incineration, brick-making and composting treatment of sludge after drying.
6. Avoid filter cloth adhesion, quick demolding, reduce the frequency of filter cloth replacement, and save operating costs.
When considering the use of sludge enhancers for sludge dewatering treatment, it is recommended to conduct small-scale trials first to determine the best type of sludge enhancer, which can not only reduce costs but also enhance the treatment effect.
