Q: What is COVID-19?
A: COVID-19 is an abbreviated term for Corona Virus Disease-2019 and is caused by the SARS-CoV-2 virus. 

Q: How might an industrial water system become contaminated by the COVID-19 virus?
A: The likely source of SARS-CoV-2 in industrial water systems is either through untreated make-up water or through aerosols produced from carrier personnel in the proximity of the system.
Untreated wastewater may become contaminated with virus particles from the excretions of symptomatic, asymptomatic, or pre-symptomatic individuals.

Q: Is there concern that municipal and potable water may be a source of transmission of the COVID-19 virus to humans? 
A: Water-to-human transmission has not yet been documented.
For municipal and potable water, current water disinfection practices are effective against non-enveloped viruses and bacteria. Current practices are also expected to be effective against enveloped viruses such as coronaviruses.

Q: Can the COVID-19 virus replicate and grow in industrial water sources? 
A: While the COVID-19 virus may survive in water, unlike certain pathogenic bacteria such as Legionella, it is not expected to multiply and grow in industrial water systems. The COVID-19 virus requires host animal cells to replicate. 

Q: Do we know how the presence of other bacteria in a water source may affect the COVID-19 virus?
A: The presence of antagonistic bacteria could adversely affect the COVID-19 virus.  However, the stability of this virus in the presence of other bacteria and biofilm in water is yet to be understood.

Q. What is the likelihood of infection by SARS-CoV-2 from an industrial water system?
A: The risk of acquiring SARS-CoV-2 infection from industrial water systems is low for several reasons:

  1. Water-to-human transmission has not yet been documented.
  2. The primary transmission mode of SARS-CoV-2 is human-to-human contact (respiratory droplets, hands, surfaces); secondary transmission can occur through human exposure to untreated wastewater with SARS-CoV-2 fecal contamination.
  3. The source of the virus will be from the use of untreated contaminated water.
  4. The virus is not expected to grow within the water system.
  5. The concentration of the virus in industrial water systems is expected to be very low.
  6. The survival of the virus in water depends on different factors, including temperature, chemical make-up, presence of antagonistic microorganisms, presence of antimicrobials (i.e. residual disinfectant levels) etc.
  7. Antimicrobial programs are used for microbial control to reduce operation performance risks

Q: Are our current microbial control programs adequate to control SARS-CoV-2 in our industrial water treatment?
A: Disinfection steps in both drinking water plants and wastewater treatment plants and the associated regulatory requirements have been developed to inactivate and kill a broad spectrum of pathogens.

According to OSHA, coronaviruses such as SARS-CoV-2 are susceptible to the same disinfection conditions in the healthcare setting as other viruses, so current disinfection conditions in wastewater treatment facilities are expected to be adequate. This includes microbial control practices such as oxidation with hypochlorite (i.e., chlorine bleach) and peracetic acid, as well as inactivation through ultraviolet irradiation.  

Q. How can the occurrence of SARS-CoV-2, and associated risks be reduced in industrial water systems?
A: Plant operations should ensure workers follow routine Best Practices to prevent exposure to wastewater, including engineering and administrative controls, safe work practices, and PPE normally required for work tasks when handling untreated wastewater.

Q: What considerations should be taken for changes in building use, and low load/no load for extended periods of time?  
A: Facility managers should consider how changes in building use will affect water management plans and make changes to those plans to maintain adequate microbial control and biological safety. Specifically, low use or no use of potable water and cooling tower systems will negatively impact the quality of water in these systems, which will likely result in the need for remediation and re-commissioning before the building or space is reopened to occupants.
For cooling water systems, low load or no load for an extended period will result in growth of bacteria and slime (i.e., biofilms). If chillers will remain off and a cooling tower is not needed, then shut it down and drain the cooling tower to prevent these problems.
If a cooling tower is still needed for low or intermittent load, keep the tower water circulating, continuously bleed water from the tower at a low rate, and continue to regularly apply and monitor adequate biocide(s)/chlorine treatment to maintain control of biological growth. Industrial systems utilizing recycle water or treated wastewater as makeup would benefit from increase in monitoring to ensure adequate microbial control treatment is implemented.

Remote service using Refined Knowledge real-time insights, allowed the petrochemical plant to avoid an unplanned shutdown.

In light of the COVID-19 pandemic and most of our operational force working remotely, the Nalco Water service team employed our unique Refined Knowledge platform to effectively identify and mitigate the consequences of a chlorine gas outage, that impacted the reliability and safety of three main hydrocarbon cooling water systems at a Texas petrochemical plant. The Refined Knowledge technology enabled the team to monitor free chlorine levels, yellow metal corrosion rate impact and cycles controlling during a four day outage; providing key insights that allowed the manual batch feed of bleach.

Using our advanced dashboard that provides critical insights, the  customer engineers and SME collaborated with Nalco Water technical and site team to analyze and compare data from all three cooling towers, allowing our team to quickly develop and implement a corrective action plan to optimize the bleach dosages. As a result, during this outage all units have continued to operate as normal with minimal impact, and avoided a potential unplanned shutdown of the plant, as well as keeping everyone safe from COVID-19 exposure by working remotely. Furthermore, we’ve successfully coupled online data with additional wet chemistry tests to continuously operate cooling water systems safely and efficiently.
