decanter

Product Details

Introduction:
Also known as a decanter, it is one of the most critical mechanical equipment in the SBR process.
It can be divided into siphon type decanter, rotary type decanter, self floating type decanter, and mechanical type decanter. Currently, the rotary type (a type of mechanical type decanter) is widely used in China.
The decanter is a device used in the SBR process to regularly remove clarified water. It has the ability to decant clarified water from a stationary pool surface without stirring the sediment, ensuring the quality of the effluent.
Due to the intermittent reaction adopted in the SBR process, the inflow, reaction, sedimentation, and drainage are completed in the same tank, without the need for a secondary sedimentation tank and sludge reflux equipment. Therefore, it has the advantages of small land occupation, low investment, high efficiency, and good effluent quality; Simultaneously connecting multiple SBR tanks can provide both the continuity of traditional sludge treatment processes (continuous inflow) and the intermittency of typical SBR processes, making it suitable for water quality, quantity, and large variations. Therefore, it has been widely used both domestically and internationally.
Applicable:
Suitable for SBR processes such as CASS, CAST, ICEAS, DAT-IAT, etc., for treating urban and industrial wastewater.
It is widely used in the treatment of industrial wastewater (waste liquid) in industries such as papermaking, alcohol, dyes, pesticides, leather, adhesives, monosodium glutamate, and sugar manufacturing.
characteristic:
The decanter can be designed with a depth of decanting according to process requirements.
1. Using PLC programmable intelligent drive, the decanter quickly moves the weir mouth from the parking position to below the water surface after receiving the drainage command, and drains the stagnant supernatant back and forth. When the decanter reaches the lowest water level, the liquid level switch placed at the lowest water level sends a return command, and the decanter quickly returns to its initial parking position, completing a working cycle.
2. Within the specified load range at the weir mouth, the liquid level below the weir mouth will not be disturbed. The weir mouth is equipped with floats and slag blocking plates to ensure the quality of the effluent water.
3. Special design ensures a basic balance between the gravity and buoyancy of the decanter, resulting in low driving power consumption.
4. The decanter is rigidly connected to the main drainage pipe using stainless steel, avoiding the drawbacks of high failure rate, short service life, and high maintenance workload caused by soft connections.
5. The entire decanter has a sturdy bracket that can withstand various stresses during operation.
