Sludge Presses Sludge from DAF (dissolved air flotation) and FBR, SBR (biological aerobic treatment) produces liquid sludge; the solids in the sludge have to removed in order to reduce the liquid volume and reduce disposal costs. Our sludge press is designed to handle all sludge types.
Reading time:10 minutes. Thickening is the first, and frequently inevitable, step in reducing the volume of sludge extracted from the water line. In fact, it is used to optimise the subsequent conditioning, stabilisation and dewatering stages by reducing structure sizes and operating costs. Extremely dilute sludge delivered by the water line (usually 99 to 99.8% water)is concentrated to produce sludge containing 90 to 96

Extremely dilute sludge delivered by the water line (usually 99 to 99.8% water)is concentrated to produce sludge containing 90 to 96% water. This sludge is still fluid and, therefore, can be pumped out. Thickening constitutes an additional investment cost and a source of possible nuisances.
Circular Thickeners provide a crucial treatment step between upstream process screens, clarifiers, and separators and downstream dewatering and sludge conditioning processes. A well-designed thickener provides storage and equalization, reduces the volume of sludge
At smaller wastewater treatment plants, where the sludge is driven off regularly, thickening usually takes place directly in the sludge storage tank. The sludge is compressed at the tank bottom only by the force of gravity, while above the sludge a cloudy water layer is
for water treatment sludge. 2) to develop curves for the evaluation of thickening of activated sludge. 3) to show the effect that temperature has on the per-formance of a continuous gravity thickener and secondary Sedimentation basins. 1-2 Gravity Thickening Gravity thickening is a process which increases the concentration
When wastewater is treated, sludge is produced. Ovivo thickeners are designed to continuously produce as thick a sludge as possible. Powered by heavy-duty drives, designed to handle the specified torque for 20 years of continuous operation, the sludge is gently mixed by rotating rake arms.
Most thickening processes require wash water for elutriation or to keep the thickener screening elements clean and functional. Depending on the type of feed solids and odor sensitivity at the treatment plant, odor control systems may be necessary. Dissolved air flotation and membrane thickeners also require a pressurized air source.

Sludge Thickening. The thickening of activated sludge is a common practice many wastewater treatment plants. These plants use a biological treatment process to reduce the wastewater COD and BOD before discharging downstream into the environment.
In WWTP, the static thickener is mainly applied on primary sludge.Recyling excess biological sludge to the primary settling tank inlet is becoming increasingly rare and, therefore, there are fewer and fewer mixed sludge applications (separate routing of primary sludge and biological sludge immediately upstream from the static thickener must be prohibited:the thickener is not a homogenisation
Thickening. Gravity sludge thickeners are an easy and cost-effective approach to minimizing the volume of waste solids. Our experts size thickeners to achieve the highest concentration of sludge with the smallest footprint.

Sludge thickening and dewatering is two important stages in treating sludge. Thickening is the first step of sludge treatment in which the solids concentration is increased and the total sludge volume is correspondingly decreased, Thickening commonly produces sludge solids concentrations between 15% and 20%, LZZG Deep Cone Thickener results in maximum water recovery, maximum underflow
The screw thickener is comprised of an inclined wedge section basket. A screw, slowly rotating with variable speed, conveys the sludge gently upward through the inclined basket. Water drains through the basket. The degree of thickening is adjustable by means of a height adjustable weir plate in the sludge discharge and the variable screw speed.
