Wastewater

A clean solution

The level of contamination of domestic and industrial wastewater differs greatly – chemically, biologically, and with regard to solid matter. Water treatment plants perform the essential function of removing contaminants and returning clean water to the usage cycle. As a plant operator, you understand the complex and often energy-intensive processes that wastewater must undergo before it reaches the required level of purity.   With our specialist software and automation technology, Siemens supports both state-of-the-art sewage plants and technologies for biological sewage treatment.

Optimal plant operation for high availability

Optimal plant operation is primarily based on high availability with minimal costs. Among other things, it requires data transparency and reliable equipment. Innovative software and proven products are valuable aids to profitable plant operation.

Optimization of sewage treatment plants

The operation of sewage treatment plants, especially the aeration of biological treatment steps, can be optimized using the Advanced Process Control functions of SIMATIC PCS 7.

Certified energy management

Company-wide energy management across sites can be a genuine challenge. With SIMATIC Energy Manager PRO, you can quickly display energy costs per generator set, machine, plant area, day, week, month, or year. When integrated into the automation system, it lets you link energy and production data as well as plant information. Instead having to analyze complex raw values, SIMATIC Energy Manager PRO combines the values and makes them accessible to you as meaningful indicators. TÜV certification of the solution makes it easier for you to comply with legal requirements in accordance with ISO 50001 and enables the energy- and cost-efficient operation of your wastewater treatment plants.

Protect plants against unauthorized access

With the growth of digitalization, comprehensive security in automation becomes increasingly important. Our Industrial Security concept includes all security levels and provides plant and network security as well as ensuring system integrity, thus providing comprehensive protection for the productivity of your wastewater plant.

Prevent faults and breakdowns in extreme ambient conditions

Mechanical loads, chemical and biological substances, condensation and temperature fluctuations reduce your wastewater plant’s durability. SIPLUS extreme technology protects your products against the resulting corrosion, dendrite and whisker formation and other harmful deposits, thereby preventing faults and downtimes. The expansion of the temperature range to -40°C and +70°C allows SIPLUS extreme products to be used even where the standard range is no longer sufficient.

Safe integration of distributed plants

Because wastewater treatment plants are often set up decentrally with many distributed external stations, centralized control is important. With telecontrol, you can control your plant remotely and easily communicate with the individual parts of the plant that are separated in terms of space or locality. Using the telecontrol units you can, for example, detect leaks, monitor pumping and storage stations, and check the levels in the tanks.

The PCS 7 Water Unit Templates provide typical components, open and closed loop control, and the necessary logic to visualize a biological stage.

Level Control

Level control in the digester is critical.

Agitators

Agitators are used for effective mixing.

Radar Level

The inventory level of chemicals used for the wastewater process must be monitored and the dosing controlled.

Magnetic Flow Meters

Flocculent inventory and dosing control are crucial for operation.

SITRANS Pressure Transmitter

The filter back-wash operation is carried out using head loss measurement across the filters using differential pressure transmitters.

Ultrasonic Level Measurement

Dewatering is typically a mechanical process, in which the sludge level must be controlled to prevent damage to the press.

The sludge from the dewatering press is transported via belt scales or by a screw conveyor, protected by motion sensors.

Motion Sensors

Water Solutions for Oil & Gas

Siemens oil and gas business includes water treatment technologies, total water treatment solutions and water treatment services.

Gear Units for Water Turbines

Water power plants use a water turbine that converts the potential flow energy contained in water into mechanical energy; this mechanical energy is subsequently converted into electrical energy in a generator. The gear units for water turbines gear up the low turbine speed into a very high generator speed.
