What are circular thickeners?
These decrease the volume of discarded sludge and enhance the solids concentration. The Circular Thickeners from Netsol Water are made to take waste sludge from different unit processes, and prepare it for dewatering and other sludge conditioning procedures.
Thickeners lower the amount of sludge, which lowers the cost of disposal and dewatering. Due to the higher sludge concentrations and densities, they require higher torque ratings than circular clarifiers, of comparable size.
Circular thickeners for the processing of sludge
Step 1: Between the upstream process screens, clarifiers, and separators and the downstream dewatering and sludge conditioning processes, circular thickeners offer a key treatment step.
Step 2: An effective thickening reduces the volume of sludge streams and raises their solids contents, while providing storage and equalisation. This makes it possible to design dewatering and sludge conditioning systems more affordably, which lowers investment and maintenance costs.
Step 3: Thickeners resemble other clarifiers in appearance and operation, but they are employed for distinct purposes, and are situated at a different step of the total water/wastewater treatment process.
Step 4: The sludge is further concentrated in thickeners, which takes in the waste streams from screens, clarifiers, separators, and other water treatment procedures. Solids concentrations in incoming water are typically between 0 and 3%. Thickened solids concentrations are normally between 3 and 6 percent, however depending on the procedure, higher concentrations may be possible.
The majority of manufacturing facilities with wastewater treatment equipment, steel mills, refineries, chemical plants, power plants, and municipal water and wastewater treatment facilities, all use circular thickeners.
Because, of the nature of the substances handled, these require higher torque ratings. Higher sludge loadings and densities need for stronger collection systems, which can withstand these bulky, frequently abrasive sludge streams.
Netsol Water uses bottom scraping rakes and strong, high-torque drives to continuously remove sludge that has solidified. In order to ensure that all settling sludge is caught and transported to the central sludge well, the rake uses numerous bottom scraping blades that are inclined.
When sludge qualities call for more mechanical agitation, thickening pickets and drive lift systems are frequently used.A thickening design package may include sludge level detectors, underflow pumps, and related piping and equipment.
Scum removal and skimming
Floating debris can include grease, oils, leaves, plastics, scum, and foam, but it depends on the thickening application.
Usually, a skimmer arm that rotates with the sludge rake around the tank is used to remove floating debris. The wipers on the skimmer arm push the floating debris over the beach plate, and into a scum box that is fastened to the tank wall. The scum outlet piping is the next stop for the collected material.
Design considerations for the thickener
Depending on the needs of the site, Netsol can offer completely integrated steel tank thickeners.
