As shown in Fig. 1, the thickener is a 22 m diameter deep cone shaped tank and its height is 16 m. In the center upper side of the tank, there is a 3 m diameter, 4 m high feed well. The feed well is attached to the 0.9 m diameter concrete support column in the center of tank. The feed inlet pipe is integrated with the feed well and

However, the low settling velocity of coal thickener feed slurry (approx 1m/s) offers design flexibility due to factors like low solids density, low feed solids concentration, and particle size. Other key design features include a tangential slurry inlet for energy dissipation without increasing froth, a bottom outlet nozzle below the thickener ...

Vector. Feed System. Open bottom designed feedwells are inefficient and typically suffer from short circuiting. The incoming feed lacks adequate mixing energy and sufficient …

Sludge Thickeners The HEI Sludge Thickener is an efficient method to gravity concentrate and decant waste sludge. Liquid sludge pumped from a clarifier will have a solids content of 0.5% from cone bottom clarifiers to 2%-4% from the rake bottom clarifiers. The sludge thickener must have sufficient capacity to accumulate and thicken the sludge between …

Gravity belt thickener model selection is a function of hydraulic feed rate; the Model G-25 thickening system is generally appropriate for 0.5% to 1.0% waste activated sludge feed rates up to 125 GPM (7.9 liters/sec or 28 M3/h) and the GSC and GSCE series machines are appropriate for higher feed rates. GSC (Three Roll)

Thickener. Prominer can provide different kinds of thickeners include center driving thickener, peripheral traction thickener and high efficiency thickener. Our thickener is applicable for dewatering concentrate and tailing slurry in the mineral processing plant. It can improve the ore pulp from 20~30% to approx. 40~70%.

Optimization experiments on feed well and self-dilute system were also carried out, and indicate that the optimal thickener system can dilute the solid concentration in feed well from 110 g/L to ...

Alfa Laval ALDRUM G3 Sludge Thickeners are ideal for mecha-nical thickening of sludge to optimize subsequent processes such as digestion with higher biogas production or …

The feedwell is the core of a gravity thickener's design and operation. It ensures the uniform distribution of the sludge and the gentle integration of the flocculant. In gravity thickeners, the design of the feedwell should promote gentle energy dissipation of the incoming feed stream, which is essential for the formation of large and stable ...

The measurable parameters that can be used for thickener control include thickener feed flow rate, feed density, underflow density, overflow clarity, bed level, bed …

The thickener is fed with sludge using a central feed well that has the function of distributing the incoming sludge as evenly as possible. The thickened sludge is collected at the bottom of the thickener and depending upon the sludge line configuration, can be either pumped to anaerobic digesters or to further dewatering equipment.
