Teledyne ISCO Water Samplers Assist in Coronavirus Tracking in Water Treatment Facilities

Coronavirus Tracking in Water Treatment Facilities

Reading the headlines today, you are seeing more and more municipalities testing their wastewater for the SARS-CoV-2 virus. Viruses and bacteria excreted in urine and stool collect in public sewers. The use of sewage pathogen monitoring in wastewater treatment facilities as a public health surveillance tool is now a reality. Environmental microbiologists have studied pathogens in sewage for decades, but now because of COVID-19, public health surveillance efforts focussing on tracking virus levels is at an all time high. It is critical that expanded testing and monitoring continue, as this will certainly help in understanding how the SARS-CoV-2 virus spreads and potentially affects community populations.

Water Samplers for Coronavirus Tracking in Water Treatment Facilities
Teledyne ISCO, the leading manufacturer of water / wastewater sampling and monitoring tools, is helping in this effort. Teledyne ISCO manufactures a complete line of robust and reliable portable and refrigerated samplers. Using this equipment as part of their overall Coronavirus strategy, municipalities have portable and refrigerated samplers ready for widespread collection and testing. These samplers can be used in any kind of environment or test situation. They are easy to use and program, and they have many configuration options.

With so little knowledge of the SARS-CoV-2 spread, this approach may be very important. The data accumulated from the implementation of large-scale sewer sampling and Coronavirus testing may provide the information needed to build dynamic virus spread maps and, ultimately, the ability to predict and prevent flare-ups.

The Teledyne ISCO 5800 Refrigerated Sequential/Composite Sampler

Teledyne ISCO 5800The 5800 Refrigerated Sampler is an automated wastewater sampler that can collect liquid samples from a variety of sources including open channels, sewers, and storm pipe conduits.

This indoor/outdoor use sampler is made of durable UV-resistant plastic that provides exceptional resistance to corrosion and weathering. Most notably, the refrigerator body is made from rotationally molded linear low-density polyethylene. This unique construction material was selected for its strength, durability, and its ability to withstand temperature extremes. The system is rated for –29 to 49 °C (–20 to 120 °F) operation. The hollow cavities are filled with foam insulation. To protect the non-CFC system, all refrigeration parts are powder coated with heat-treated polyester.

Unattended sample collection events can be triggered by time intervals (time pacing), or by flow volume measured by an external flow measurement device (flow pacing or constant volume variable time). Isco flow meters are compatible flow measurement devices, as well as any device that can provide a 5 to 15 VDC pulse or contact closure of at least 25 mS duration, or a linear 4-20 mA current loop signal. An external device can also disable the sampler until measured site conditions are met, at which time the sampler begins the automated collection.


The sampler’s pump can deliver the liquid through a 9 mm (3/8") suction line at transport velocities of at least 0.9 meters per second (3.0 ft/sec) at 0.9 m (3.0 ft) of head. The transport velocity at 7.6 m (25 ft) of head is 0.67 m/sec (2.2 ft/sec). The maximum lifting height of the sampler is 8 m (28 ft). To produce accurate and repeatable samples, the pump uses a pump revolution counter and non-contacting liquid detector.

The collected samples are stored inside the refrigerated compartment and cooled for sample preservation. Samples can be deposited into a single bottle (composite), or collected as discrete samples, each into a separate bottle of a multi-bottle rack (sequential), or a combination of these modes. The cooled samples are maintained until an operator can remove them from the sampler and deliver them to the laboratory.

Process Control Safety Case Study: Fluid Catalyst Cracker Explosion

A case study of the 2018 Husky Energy refinery explosion in Superior, WI. This animated video recaps the events and circumstances leading up to an explosion starting in the Fluid Catalyst Cracker (FCC). The key factor was an eroded sliding gate valve that allowed a protective layer of reactor catalyst to leave it's containment area. This allowed air and hydrocarbon to blend, forming a combustible mixture, and setting the stage for a chain reaction of events. This video, courtesy of the Chemical Safety Board ( is an excellent educational reference and should be viewed by engineering, maintenance, and plant management personnel everywhere.

Instrument Valves: The Difference Between a Rotating One Piece Stem and a Non-Rotating Two Piece Stem

Process instrument valves are used with devices such as pressure measurement transmitters, gauges, and switches to isolate the device from the process media for replacement, calibration, and maintenance. Instrument valves are combined together and assembled into block and bleed manifolds combing multiple valves into a single body configuration, with each valve having a separate external connection and a common internal connection.

A critical component to the instrument valve is the valve stem. The stem positions the stem point into the orifice and against the valve seat to control flow and to isolate the process.


A rotating one piece valve stem rotates and translates along its axis as it is being driven axially into the orifice. The rotational motion of a one piece stem can produce friction as the stem interacts with the seating area, which could result in galling at the seating surface. This is less of an issue in a soft seat valve or if the media provides lubrication.

A non-rotating two piece stem tip rotates independently from the stem and stops rotating as it is driven axially against the orifice sealing surface while the stem continues its rotational and axial movement.

PVC Flow Meters for Water and Corrosive Applications

PVC Flow MetersPolyvinyl chloride (PVC) is the world's third-most widely produced synthetic plastic polymer and is chemically resistant to acids, salts, bases, fats, and alcohols.

Orange Research manufactures a line of PVC flow meters and PVC switches for water and corrosive liquids applications with wetted parts of PVC and Teflon. They’re perfect for difficult environments where aluminum, stainless steel or brass is not appropriate.

Their models 2221 and 2321 variable area PVC flow meters handle flow ranges from 0-1 to 0-10 GPM. The PVC bodies handle up to 200 psi pressures. Alternatively, metal pressure bodies with PVC and Teflon wetted parts are available and can handle up to 3000 psi line pressures.

These flow meters also include dials made from durable ABS plastic and offer switches (to alert users of alarm conditions) as a standard option. Transmitters are also available upon request. Accuracy is 2% F.S. and each unit is calibrated to NIST standards.
