Efficiently service and maintain intelligent field devices
Field devices are the eyes and ears of automation. The failure of a valve positioner, temperature, flow or pressure sensor can quickly lead to serious malfunction of the process. With SIMATIC PDM Maintenance Station V3.0, Siemens offers the right solution for efficiently monitoring the condition of smart field devices, irrespective of the automation and control systems used

Oily water filtration was developed for filtering free oil and suspended solids from produced water or refinery wastewater, to be disposed of, re-injected, discharged or reused. These systems primarily used black walnut shell media, and required expensive treatment upstream to limit the filter loading rate.

Siemens’ Revive™ oily water membrane systems replace both filtration and flotation with a single step, eliminating the need for polymers and allowing for better oil recovery. Revive™ systems can achieve Oil & Grease and Total Suspended Solids levels of <1 mg/L, and Silt Density Index of <3.

Corrugated Plate Separators (CPS’s) provide economical and effective removal of oil and solids from wastewater by gravity, in a smooth, efficient automatic flow. With thousands of installations in operation, this proven design has no moving parts and provides consistent operating results for simple and better separation.

The Folded Flow® DAF system’s simple and innovative design “folds” the flow by removing effluent from the same end of the tank as the influent is introduced, resulting in a higher hydraulic loading rate.

Hydrocell™ hydraulic induced air flotation separators remove oil and suspended solids from water in large volumes, and can process solids and oils from 50 ppm to several hundred ppm with product effluents containing less than 5 ppm.

The PACT system combines biological treatment and carbon adsorption into a single, synergistic treatment step, resulting in significant cost savings and performance advantages over other systems.

Siemens Water Solutions offers a complete line of products to remove oily contaminants from water. Our newest addition to this line of products is the Monosep high-flow walnut shell filter, offering improved technology in walnut shell filtration.

The patented Veirsep horizontal flotation system incorporates several unique technologies to separate oil and various other contaminates from produced water and contaminated wastewater streams.

The Spinsep vertical flotation system incorporates several unique methods for removing oil from produced and wastewater streams before they are discharged or injected.

Siemens’ industry-leading Brise™ bubble generating pump technology has been enhancing flotation systems in the Oil & Gas industry for over 20 years.

And now, our new Brise™ 2.0 pump continues – and improves – that tradition of superior flotation performance, and helps save you money, in an ever-changing oil production market.

Our patented Combosep (COMBination Of SEParators) is typically comprised of a vertical and horizontal flotation system, mounted on a common skid, complete with interconnect piping.

The high efficiency liquid/liquid hydrocyclone provides maximum oil/water separation efficiency, and is used in industrial process water, industrial reuse, oil/water separation, and clarification/separation applications

This filter uses variations of different medias in a downflow pressure filter configuration. The flux varies with different applications and can range from 5 GPM/ft² for some mining applications to 20 GPM/ft² for offshore seawater filtration

Zimpro Wet Air Oxidation (WAO) systems are used primarily for treatment of high strength industrial wastewater streams.

API Oil/Water Separators are the performance, safety and environmental standard for petroleum refineries throughout the world

Auto-Shell walnut shell filters remove oily contaminants from water, and are used in treating oilfield produced water, refinery wastewater, steel mill direct spray and caster water, ethylene plant quench water, copper concentrate decant and cooling water


From biological and oily water treatment to the treatment of high-strength, complex wastewaters, Siemens Water Solutions brings years of proven expertise and real-world experience—allowing us to help you manage risk while achieving operational performance goals. We also offer comprehensive feasibility and pilot studies, in addition to complete aftermarket services. Download our new downstream capabilities brochure today.

Produced water is generated in the process of lifting oil and gas from water-bearing formations–typically sea or lake beds. As oil and gas is lifted to the surface, water is brought along with it. This water must be treated prior to discharge or re-injection.

Meeting water quality specifications for injection or reinjection is essential for protecting the permeability of a reservoir.

The treatment of process water can have a substantial and serious impact on a facility’s bottom line results in the short term as well as over the life of the equipment.

In the last 10 years, we have successfully installed over two dozen spent caustic wet oxidation systems, with capacities varying from 0.5 to 18.5 m3/h (2 to 81 gpm). Our systems are the industry standard and are included in many of the new world-scale ethylene plants.

  • 3 Dirty Little Secrets About Coriolis Flowmeters

    Ever since Coriolis flow measurement technology achieved mainstream appeal, industry has been fervently striving to take advantage of its benefits. And while Coriolis is clearly a highly advantageous solution for many crucial flow measurement applications, it is not without flaw.

  • From The 1970s To Today – 4 Key Advances In Coriolis Flow Measurement

    Since the first Coriolis flow sensors were introduced to the marketplace in the 1970s, the technology has evolved considerably. As the installed base for Coriolis grew, the sensors were being called upon to deliver data in environments with increasing levels of complexity. This meant that Coriolis sensors had to adapt and conform to a dizzying array of ever-changing installation requirements, process conditions, communication formats, and configuration parameters. The following article highlights four key advances in Coriolis flow measurement’s journey from the 1970s to today.
