Minimum Space, Maximum Efficiency

The Wagner Fluid Systems Sequence Batch Reactor (SBR) is an aeration process for the complete treatment of municipal, industrial, and agricultural wastewater. The process takes place in a single tank and is capable of removing BOD, ammonia, and suspended solids and nutrients (including nitrates and phosphorus). The system treats sewage in a series of four distinct sequences.

Each reaction estimates a total of four hours to complete. An initial fill cycle allows raw sewage to enter the tank. An aeration cycle then converts non-volatile sludge (humus), and ammonia is oxidized to nitrate. After the aeration cycle is complete, a precipitation phase allows the sludge to settle under quiescent conditions. Treated effluent is then decanted from the tank during a decant phase, after which, the cycle is repeated.

The SBR typically consists of two or more tanks, allowing one tank to discharge treated effluent while another tank is available to accept sewage flow. The process contains minimal in-basin equipment ensuring affordable capital cost. The simple design and ease of operation ensures reduced maintenance and operation expenses.

Key Points

• Food processing, industrial, and municipal wastewater applications
• One tank for all cycles and steps: fill, react, settle, decant, and idle
• Complete effluent treatment, including nutrient removal
• Tolerates variable hydraulic and organic loading
• Offered in both continuous and batch operating modes
• Precisely controlled positively driven jack-screw decanter
• PLC (Programable Logic Control)

Vertically Driven, Highly Reliable

The heart of every Sequence Batch Reactor (SBR) system is the decanter. The decanter is responsible for removing clarified effluent from the basin during the decant phase of the sequence cycle.

The Wagner Fluid SBR by Ram Industrial Services is an advanced SBR technology designed for both batch or continuous inflow. All SBR processes are operated using defined cycle times adjusted to variable flow conditions. Each cycle typically consists of four main phases: fill, aerate, settle, and decant. The basin may be aerated-fill or anoxic-fill during the first half of the cycle. After the aeration phase, the system goes into a settling phase where liquid/solids separation occurs. In the final step, clear water is decanted out of the basin.

The WFS decanter is installed on the basin wall supported by a stainless-steel fabrication, grating and railing that provides a stable platform for maintenance and plant operators. The decanter is lowered and raised using an electro-mechanical jack screw actuator. The actuator moves the decanter between two set point elevations from the “park” position to the bottom water level (BWL). The decanter parks above top water level during the aeration and settling phases of the cycle, thereby eliminating any possibility of solids carryover during these periods.

The decanter operation and speed is controlled through use of a variable frequency drive (VFD). As a result, the decanter discharge rate is constant from the time the decanter enters the water to the time it reaches the BWL. Effluent volume per linear foot of weir is controlled and constant versus gravity style decant systems.

At “park” position, the decanter provides fail-safew overflow protection in the event of a power failure. Settled supernatant flow raise the scum gate floats allowing water to flow under the scum baffle and over the decanter weir free of floatable scum under power failure or storm mode.

The decanter weir always is visible from the basin walkway. This feature provides the operator with a continuous visual check of the effluent quality.

The Wagner Fluid System decants from the top and moves downward withdrawing only clear water from the basin and preventing disruption of the settling solids. All maintenance can be performed from the safety platform without entering the basin.

Engineered to Optimize Performance

The extended aeration wastewater treatment plant is based on a time-proven, conservative process design, and engineered to optimize performance. Extended Aeration wastewater treatment plants are one of the simplest, economical and most versatile methods available to treat sanitary, industrial or agricultural wastewater. Treatment plants meet or exceed effluent parameters for most wastewater applications and are economical to install and operate.

Extended Aeration treatment plants provide the proper environment, sufficient oxygen, and other elements which allow the bacteria to consume the organic matter to live and multiply within the treatment plant. In this way the aerobic bacteria and microbes decompose the sewage and waste to a stable form free of odor and costly maintenance. Each plant consists of two major compartments, the main aeration chamber and a clarifier or settling tank. After initial screening, the wastewater enters the main aeration tank, which has a retention time of approximately 24 hours. Here, natural bacteria feed on the organic fraction of the sewage and reduce Biochemical Oxygen Demand (BOD) concentrations. The partially treated sewage then flows to the final settling tank for clarification prior to discharge. The effluent may be filtered and disinfected, depending on discharge permit requirements.

Time Proven: Tried & Tested

Wagner Fluid Systems “De-Nite” denitrification and tertiary filtration system provides a time proven process for the reduction of nutrients (Nitrate-N and Phosphorus) as well as suspended solids from the effluent of wastewater treatment plants.

The process accepts secondary effluent by gravity or lift station to a distribution box with automatic control valves. The distribution box and control valves direct water to each filter cell in proper sequence. The anoxic biological process and conversion of Nitrate-N to elemental Nitrogen gas takes place on a fixed film of bacteria residing on and within a coarse mono media.

The down flow design of the Wagner Fluid Systems “De-nite” Filter effectively reduces suspended solids and phosphorus by addition of Alum and mechanical filtration through the bed. The anoxic bacteria require a carbon source as supplement which may include Methanol, Acetic Acid and other proprietary chemistry.
