Experts in Sludge Treatment Pumping Applications
Sludge treatment is a key element in the environmental sector for wastewater treatment plants, whether for industries or municipalities. At PCM, we offer reliable, efficient and sustainablepumping solutions for every stage of the sludge management process, whether liquid, thickened or dewatered.
Challenges
Process
Liquid Sludge Transfer
The first step is to transfer the abrasive liquid slurries from the primary sedimentation ponds to the dewatering or thickening systems.
Thickened sludge disposal
After the first stage of dewatering, the sludge becomes more viscous and contains up to 10% solids, requiring a suitable pump to prevent sedimentation. This sludge is discharged to drip tables, belt filters, or dynamic thickeners.
Pumping of dewatered sludge
After a second stage of dewatering, the sludge reaches a solids content of up to 45%, requiring resistant equipment to ensure smooth transfer.
Process
Preparation of the concentrated and diluted polymer
Polymers are essential for binding sludge and facilitating its processing. The use of progressive cavity pumps is ideally suited for transferring the concentrated polymer as well as the dilute polymer in the slurry.
Polymer dosing is a crucial step, it must be accurate so that the polymer is diluted perfectly and directly in the fluid, in order to facilitate the treatment of the sludge and its transfer.
Chemical dosing
Chemicals, whether liquid or solid, play a vital role in the sludge treatment process by facilitating its neutralization. Some of the main chemicals used include milk of lime, ferric chloride, sulfuric acid, and hydrogen peroxide.
