wastewater decanter Sequencing Batch Reactor Activated Sludge Process SBR

Product Overview

Description

 Rotary decanter :

   Rotary decanter is based on the digestion of foreign technology development, specially designed for sequencing batch type biological treatment system, has the good performance of hydraulic machinery. Can realize the decantation during the process of water into the water weir flow in laminar flow state, decant the water depth is adjustable, make the water yield is adjustable, is the key to the circulation process of activated sludge system equipment.

 

product overview:

   as the supernate drainage device,is applied to various intermittent circulatory activated sludge process of sewage treatment system(such as SBR and CASS).considering influence of scums in the water surface and sludge at the bottom to the water drainage quality,a floating barrel is set in front of thr decanter basin,which ensures collection of supernate without scums or sludge at the bottom.

   Rotary decanter is composed of decantation water device, transmission device, skimming buoy device and rotary bearing, etc. Driving mechanism through scalable push rod drives the decantation water device and skimming buoy device around the rotary bearing rotation, thus make the decantation water weir crest moved up and down, to decant out that the purpose of supernatant fluid.

   Rotary decanter can design according to the technological requirements decantation water depth.

   Rotary decanter drainage instructions received after rapid move decantation water weir crest by the position below the surface of the water stop, drainage; To be after the clear water, revolving water decanter was quickly put decant been instructed drainage water weir crest by parking position below the surface to stop, drainage; So again and again...

    When rotary decanter on arriving at the lowest water level, the return instructions on the lowest water level of the liquid level switch, revolving water decanter quickly back to the original position, to complete a working cycle.

    Within the scope of the provisions of the weir crest load, weir crest under the liquid surface disturbance. Weir crest with the buoy and slag plate to ensure that effluent water quality.

 

Special design to ensure water decanter gravity and suffered buoyancy basic balance, make the drive power consumption is low.

 

The main drainage pipe is a stainless steel rigid connection, to avoid the caused by soft connection failure rate is high, short service life, maintenance work intensity and other ills.

 

The whole water decanter with strong support, can work under the various stress.

 

 

Benefits:

• Free movement in vertical direction, maximum distance from sludge layer during sedimentation

and decanting.

• Floating sludge does not influence effluent quality.

• Low velocity of flow resulting in low risk for occurrence of whirls and sludge waste.

• Prevention of sludge penetration into outflow pipe.

• A minimum of maintenance work and no electrical equipment.

.Strong adaptability, through internal parameters set and adjust the frequency converter, can change the    running speed of the water and the corresponding movement range, adapt to different water requirements

.Sealed rotary joint, flexible rotation, good sealing, no drainage can replace the sealing ring

.Underwater parts are all made of stainless steel, do not need maintenance, drive and control equipment maintenance is convenient

.The whole water decanter with strong support, can work under various pressure encountered

.Water decanter adopt fission structure, easy to transport and install

.Elaborate structure, beautiful appearance, save installation space
