Sequencing Batch Reactor

The SBR system accomplishes equalization, biological treatment and settling in a timed sequence. A sequence consists of five main phases: Fill  React  Settle  Decant  Idle These main phases can be divided further into sub phases depending on the treatment. The result is a very simple and flexible system that can be adapted to the specific conditions. In the system the reaction tank is filled with raw wastewater. During the fill phase and the subsequent react phase, the wastewater is treated biologically. The reaction tank can perform both nitrification and denitrification which means that the plant can offer the needed conditions where the water is instead of pumping the water to another tank with the right conditions. As a result, the need for an internal recirculation is eliminated. After the biological treatment a settling phase is initiated. As the system includes internal sedimentation, the need for an external clarifier with recirculation of sludge is also eliminated. After sedimentation the treated water is discharged from the system before new wastewater is admitted. As it is seen the water volume in a SBR system varies during a sequence.  Advantages

Lamella Clarifier

Lamella Clarifier

We offer lamella clarifier to achieve solid-liquid separation by directing the liquid between a series of inclined plates called lamella. The settling surface of each plate is equivalent to its horizontal projection. Lamellae are normally spaced approx. 50 mm apart, with the result that large settling surfaces are concentrated within a relatively small floor area. Stacking the inclined plates results in the separator having upto ten times the clarification area of a conventional circular settling tank occupying the same floor space. In other words, for the same liquid flow, the lamella clarifier would occupy 1/10th the floor area of a conventional clarifier.
