SBR FLOATING DECANTER

SBR Rotary Floating Decanter

Introduction

The rotary decanter is specially designed for large-scale sequencing and batch biological treatment systems. It can realize the laminar flow state of the water entering the outlet weir during the decanting process, and balance the falling speed so that the water output remains unchanged. It is a circulating activated sewage treatment system. Key equipment for mud process.

The rotary decanter is an important equipment in the Sequencing Batch Reactor Activated Sludge Process (SBR). It is also the most widely used in domestic. This kind of water decanter can work steadily, easy control, no leakage, flow smoothly and not disturb the sludge. Since the SBR process using a batch reactor, not need secondary sedimentation and sludge return equipment, can save a lot of investment in infrastructure and with good treatment effect, which has been widely promoted in our country. Its basic operation procedure composed by water fill, react, settle, draw and idle five basic process. It's a complete cycle from waste water fill to its idle. The rotary decanter achieves the function to drain the treated water quantitatively and regularly, that makes it possible to continuously treat the water in SBR pool which is the final purpose.

Work Process:

During the aeration and settling phases, the decanter is located above the high liquid level in the main aeration zone. When decanting water, it drops below the water surface for drainage. When the water level drops to the low water level, the decanter returns to the initial position.

Features:

The decanter realizes automatic speed change during operation and has a wide adjustment range. The operation of the equipment is synchronized with the water level drop, and the drop speed is uniform speed. The operating speed during decanting can be selected according to different water qualities. It is different from the slide lifting device, but also different from the pneumatic or hydraulic lifting device.
The frequency converter used in the electronic control system is installed in the local control box, which can not only control manually on site, but also accept control signals from the PLC in the central control room to achieve automatic control.
The entire process of water discharge can prevent scum on the water surface from entering the outlet weir.
The underwater rotating parts have good sealing performance, the sealing ring has a long service life and is easy to replace, ensuring the quality of the effluent water.
The decanter is subject to limit control during its operation. to protect the organization from damage.
The driving mechanism is stable and reliable, consumes little power and has low operating costs.
The whole machine has compact structure, easy operation and convenient maintenance.

Equipment Structure

The decanter is composed of a decanting device, a transmission device, a skimmer float device and a slewing bearing. The driving mechanism drives the decanting device and the skimming float device to rotate around the slewing support through the telescopic push rod, thereby moving the decanting weir up and down to achieve the purpose of decanting the supernatant liquid.

Screw Type(L)

L-type (screw type) rotary decanter consists of a water collection tank, a float, a drainage pipe set, a slewing support, a screw, a connecting rod device, a guide rail and a transmission device.

Electric Push Rod Type(D)

D-type (electric push rod type) rotary decanter is mainly composed of a water collection tank, a float, a drainage pipe set, a slewing support, an electric push rod and an electric control box.

Float Type(F)

F-type (float type) rotary decanter is mainly composed of a water collection tank, a float, a drainage pipe group, a solenoid valve, a liquid level gauge and an electric control box.
The electronic control part of the decanter can be controlled by frequency converter and PCL, and can realize manual and automatic control.

When draining water, the control element gives a signal and instructs the transmission device to work. The nut rotates and the screw descends at a constant speed, so that the support rod moves in a certain trajectory or is pushed by an electric push rod. The water collection trough moves down at a set speed to complete uniform decanting. water. After the decanting is completed, the liquid level controller gives a signal, the motor reverses, and the water collection trough is moved upward and returns to the preset position.

The decanter can follow the water level to continuously and quantitatively drain water. The decanting depth is large, the action is smooth and reliable, and the liquid level is not agitated. The whole machine consumes less energy and has a long service life.
