Structure and Working Principle
The control of the sludge thickening tank includes the control of
the amount of sludge entering and the amount of concentrated sludge
discharged. Under normal circumstances, there is no sludge storage
tank before the thickening tank, so that the sludge discharged from
the sewage treatment system directly enters the thickening tank.
Therefore, the control of the thickening tank mainly refers to the
control of the discharge of concentrated sludge. The control
methods of concentrated sludge discharge mainly include:
(1) Use a timer to control the start and stop of the mud pump;
(2) Use timers and preset counters to control the daily discharge
of a certain amount of concentrated sludge;
(3) Use a timer to control the start of the sludge pump, and use a
sludge concentration meter to detect when the sludge concentration
drops to a certain set concentration and stop the pump;
(4) Use a timer to control the start of the pump, and use a sludge
concentration meter, a flow meter and a preset counter to control
the stop of the pump when a certain amount of solid matter (in
terms of dry sludge mass) is discharged every time
Description
Structures used for sludge thickening. Generally, it adopts a
vertical flow or radial flow shape. It can be divided into
intermittent operation and continuous operation. The former is
mainly used in small sewage treatment plants or sewage treatment
plants of industrial enterprises, and the latter is used in large
and medium sewage treatment plants. The form of the continuous
gravity thickening tank is the same as the radial flow
sedimentation tank. It can be divided into three types: scraper and
sludge mixing device, without scraper, and multi-layer thickener
(with scraper).

Main Features
1. The inlet and outlet troughs around the sedimentation tank are
designed with side-sections to ensure uniform water distribution
and outflow around the sedimentation tank.
2. The driving device adopts a combination of a helical gear
reducer and a worm gear reducer to ensure the output torque and
speed, and the transmission effect is high; the reducer is equipped
with an excessive torque protection device, which is safe and
reliable in operation.
3. When φ≤40m, a single-sided straw is used, and if φ>40m, a
double-sided straw is used.
4. The sludge suction pipe uses a horizontal perforated pipe to
discharge the sludge, which does not interfere with the density
flow in the tank and ensures the stability of the water.
5. sludge suction on the cone-shaped sludge suction pipe is
uniquely designed and adopts variable hole pitch, from inside to
outside, from small to large, to ensure balanced sludge suction at
the bottom of the whole pond, increase sludge suction
concentration, and save sludge backflow power.
6. There are two ways of skimming: plate skimming and tube skimming
(the former is conventionally used).
7. The equipment is easy to operate, and the operation of the
equipment can be directly controlled locally/remotely.

Packing and Delivery
1. Waterproof packing with the international export standard by
20ft, 40ft, 40hp container. Equipment Fittings, Electric Motor and
Power Cabinet will be packed in Wooden Case or Iron Box. Other
Equipment will be packed by Color-Stripes Plastic Cloth.
2. The whole plant machinery size are large as normal, so we will
use Waterproof cloth to pack all of them. The motor, gear box or
other easily damaged parts, we will put them into box. We have a
professional shipping department, they will try their best to save
your container quantity.
