Sludge enhancer is a chemical agent specially used to improve sludge dewatering performance, which can mainly solve the following problems:
One. Reduce sludge moisture content
Sludge synergists can change the surface structure and properties of the sludge, reduce the surface load and specific surface area of the sludge solid, destroy the colloidal structure and bacterial structure in the sludge, and make the sludge particles easier to separate and dehydrate. When used in conjunction with industrial equipment such as filter presses, the sludge enhancer can significantly reduce the moisture content of the sludge. For example, after the introduction of a sludge booster in a sewage treatment plant, the water content of the dehydrated mud cake is reduced from the original 80% to less than 60%, and the water content of the sludge can even be reduced from more than 90% to 40% to 60%.
Two. Improve sludge dewatering efficiency
The sludge synergist can destroy the colloidal structure of the sludge, reduce the viscosity of the sludge, and make it easier to remove the water in the filter press or centrifuge and other equipment. At the same time, it can also make it easier for solid particles in the sludge to gather together, thereby increasing the solid content of the sludge. These effects together improve the dewatering efficiency of the sludge, shorten the dewatering time, and reduce the operating time and energy consumption of the dewatering equipment.
Three, simplify the sludge treatment process
Because sludge synergists can improve the colloidal structure and viscosity of the sludge, some tedious pretreatment steps (such as long stirring, adjusting pH value, etc.) can be simplified or omitted. This reduces the complexity and cost of sludge treatment and improves the treatment efficiency.
Four, reduce equipment maintenance costs
Sludge enhancer can improve the fluidity of sludge and reduce the wear and blockage of sludge to dewatering equipment. This not only extends the service life of the equipment, but also reduces the maintenance cost of the equipment.
Five, reduce the burden of follow-up treatment
After dehydration, the moisture content of the sludge is reduced, and the volume is reduced, which is convenient for subsequent transportation, storage and disposal. This reduces the burden of subsequent treatment, reduces treatment costs, and helps to achieve sludge reduction, stabilization, and harmless treatment.
Six, avoid equipment corrosion and filter cloth clogging
Unlike traditional water treatment agents that require lime to achieve dehydration, sludge enhancers do not require lime to be added, so they do not corrode equipment or clog filter cloth. This facilitates the subsequent treatment of the sludge, such as incineration, brick making and composting.
In summary, sludge synergists have a wide range of application prospects and significant advantages in the field of sludge treatment. It can solve the problems of high sludge moisture content, low dewatering efficiency, complex treatment process, high equipment maintenance cost and heavy follow-up treatment burden, and bring significant economic and environmental benefits to sewage treatment plants and industrial wastewater treatment facilities.
