Sludge Thickener

Sludge Thickening - an overview | ScienceDirect Topics

The sludge concentration achieved in the thickener is independent of the feed concentration. However, the greater the feed volume, the larger the thickener required. There are several thickener designs in use; most are of the settlement type developed for industrial applications, which uses heavy duty scrapers with a picket fence attachment.

Sludge Thickening - HUBER SE

This volume reduction is achieved by the separation of parts of the sludge liquor at different points within the sludge treatment process chain. The main field of application for thickening systems is volume reduction of primary and excess sludge prior to stabilisation.

Sludge Thickening - Degremont®

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.

What is the Sludge Thickening Process in Water Treatment ...

06-03-2018· Sludge flows into the thickening tank, and eventually, it removes excess water from the solids collecting at the bottom. A gravity thickener has a similar process to the tanks, but it has a sloped design so that solids collect at the base. Dissolved-air flotation is another type of sludge …

Sludge Thickening - Aqseptence

The quantity of primary and surplus sludge is reduced as a result of sludge thickening procedures and disposal costs are, therefore, lowered. Special stirring and scraping mechanisms reduce the water content of the sludge in the sludge thickening tank and enable a continuous removal of still pumpable, free-flowing sludge into a collection hopper.

Thickener - Ovivo

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.

Sludge is led inside and through the drum over the flow edge. The spiral screw transports the sludge along the drum and finally out from the drum. The spiral screw mixes sludge slowly inside the drum so that water can come out from sludge very effectively. The horizontal position of the thickener can be lifted up to 10 degree.

Sludge Thickening - an overview | ScienceDirect Topics

Sludge drying beds are often used for small sludge volumes, which drain and dry rapidly. Application is usually restricted to the more arid climates. A schematic is presented in Figure 14. The filtrate is returned to the treatment plant. About 10–30% solids can be expected depending on specific application.

PowerDrum (PDR) Drum thickeners for sludge thickening

The PowerDrum (PDR) drum thickener for sludge thickening may also be used to lower the hydraulic capacity of the dewatering equipment installed in the downstream process. The sludge is conveyed inside the drum due to the drum inclination, as well as the combined action of the drum’s rotating movement and its internal design.

Sludge settles in gravity thickeners and is compressed by the weight of its own solids. Due to their higher specific density, primary and digested sludge can be better gravity-thickened than secondary sludge. Secondary sludge (e.g. waste activated sludge) is preferably thickened mechanically, separate from primary sludge.

The sludge thickener must have sufficient capacity to accumulate and thicken the sludges between filter press cycles. To efficiently operate a filter press, the solids concentration in the filter press feed should approach 10% solids by weight. A typical filter press will produce a filter cake having a solids concentration of 30% by weight.
