Wastewater

Pump Station Control requires monitoring of water level in the wet well. Level, volume, flow and the pump need to be controlled continuously.

SIRIUS ACT offers a unique portfolio of pushbuttons, indicator lights and switches. Designed for rugged reliability and critical operations - even oils, caustic solutions and extreme environmental influences cannot disrupt operation.

Open Channel flow monitoring requires highly accurate data of influent flow to meet regulatory demand.

Water screw pumps rotate in an open concrete trough and are used to lift water in sewage treatment and drainage plants.

The ratio of Return Activated Sludge (RAS) to Waste Activated Sludge (WAS) is critical and may be controlled using Magnetic flow meters.

Aeration required in the biological part of a sewage plant swirls the surface of the water so it is enriched with oxygen. This activates the bacteria, so the biodegradable constituents are removed from the sludge.

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 in the digester is critical.

Agitators are used for effective mixing.

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

Flocculent inventory and dosing control are crucial for operation.

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

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.

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

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.
