Municipal WWTP

Biological Treatment Plants

Biological activation treatment plants with complete aerobic sludge stabilization, ensuring nitrification, denitrification, and partially biological phosphorus removal.

System Advantages

The used SBR technology requires significantly less space than conventional technologies. Operation does not require the constant presence of an operator, it is fully automatic.

Control Process

The operation of the treatment plant is controlled by an industrial computer which optimizes the plant’s operation in real-time depending on the quantity and quality of the wastewater.

Monitoring

The control system of the treatment plant can be connected to a remote data transmission to the central dispatching center via phone or the internet.

Technology Description

This is an intermittent operation technology controlled by an industrial computer. Unlike continuous treatment plants, this type of technology omits the settling tank. The wastewater treatment process occurs in one tank due to the intermittent operation. The following phases alternate successively:

• Filling
• Activation
• Sedimentation
• Decantation phase (emptying)

Each phase can be modified and adjusted to be optimally adapted to treat the incoming wastewater.

Technology Design

Given the system’s high variability, practically each treatment plant is designed with adaptations to the specific situation. The technology can be installed in tanks of any shape and material. Adhering to the necessary reactor volumes, the treatment plants are designed for any number of PE (Population Equivalent).

Treatment plants are typically equipped with blowers and pumps from various manufacturers, depending on the investor’s requirements (cost, reliability, etc.). A unique feature of our WWTPs is the specially assembled control systems, which are mostly integrated into one unit with the power distribution board.

Remote Control of WWTP

For all municipal WWTP technologies we implement, we offer remote data transmission. Remote control of TOPAS WWTP operates at 3 levels:

1. Computer unit at the WWTP – real-time WWTP control, data recording
2. Connection of the WWTP to the dispatch center – daily approx. 2-minute data transmission, minimal communication costs, immediate reporting in case of malfunction (landline, GSM)
3. Remote control dispatch center – an experienced technologist evaluates the data – if necessary, dispatches service technicians to rectify the malfunction

Advantages of SBR

• Handles uneven flows
• High and consistent water quality at the outlet
• Lower operating requirements compared to other systems
• Great flexibility
• Reliability
• Simplicity
• Lower space requirements compared to continuous systems
• No direct hydraulic connection between inflow and outflow

WWTP Control

The treatment plant is equipped with a control unit that immediately responds to changing wastewater inflow and adjusts the cleaning cycle according to the actual load. This ensures both an increase in potential hydraulic capacity in case of rain and a reduction in performance, energy saving, and sludge regeneration in case of lower inflow.

The control unit is adapted for remote data transmission and can thus be operated from a dispatch center.
