More harm than good? 2 potential pitfalls of dilution control systems (DCS) And, how ready-to-use wipes can avoid them
In our last blog post, we introduced the topic of DCS with a focus on risks associated with microfiber textiles. But when using a DCS, there are other important aspects to think about – for instance, has your team considered the many factors involved in ensuring the systems operate as expected, and the water characteristics are appropriate? In today’s post, we dive deeper into DCS by highlighting two potential pitfalls: 1) human and/or system error; 2) fluctuating water quality.
Truthfully, when requirements are not met, dilution control efforts meant to protect patients, staff and visitors can actually spread infection. But with ready-to-use wipes, you can avoid these potential pitfalls entirely. Read on for some important questions to ask as you evaluate your sanitization and disinfection approach.
1. Have you considered the potential risks associated with the functioning of the DCS itself?
Is your DCS dispensing the right chemical concentration every time?
- A 2015 study identified variations in quaternary ammonium compound (QAC) concentrations delivered by the facility’s dispensing stations. In fact, none of the dispensing stations surveyed yielded the right in-use concentration of 800 ppm. Of the 33 dispensing stations surveyed, concentrations were inconsistent across 30 stations, two stations were empty and one station was inoperative.1
How often is your machine maintained to ensure proper dilution? Are you performing quality checks? And have you considered the potential labour/material costs associated with a malfunctioning or poorly maintained DCS?
- Another study, published in the Canadian Journal of Infection Control, evaluated the reliability of automated DCS for concentrated accelerated hydrogen peroxide (AHP) disinfectant in a 1,000-bed hospital. Nine quality control failures were detected during a 30-day testing period – seven failures involved the DCS disposing well below the acceptable concentration; two disposed well above the required concentration.2
Have you considered the consequences of using the same solution on all surfaces?
- If chosen DCS disinfectants do not have an acceptable compatibility profile with all surfaces used, they may cause damage during routine use (i.e., plastic fatigue, discolouration, metal corrosion).

If you aren’t auditing your DCS, your team may be contributing to an unsafe environment. Ready-to-use wipes, however, are consistently effective, by design. Click here to read more about the efficacy of ready-to-use wipes when compared to dilutable products.
2. Have you considered the potential risks associated with the water used in the DCS?
Is your water compatible with your dispenser design?
Any substances that are not H20 in your facility’s water are considered impurities – and that can be problematic to your DCS. You also need to consider:
- Water pressure: If too weak, it can affect how much water is in your concentration; if too hard, it can affect the potency of the chemicals mixed in the DCS
- Temperature: Water that’s too hot or too cold can impact the concentration of the DCS disinfectant
- Total hardness, pH, conductivity: The status of your water hardness (ppm CaCO3/L), pH @ 25°C, conductivity (µmhos/cm) can affect how your water performs with your dilution system
- Minerals: Cu2+, F-, K+, HCO3, Mg2+ can be corrosive to your DCS, and impact its performance. These and other factors can affect and eat away at certain components of your DCS
Is your water being tested for the presence of microbes? How often?
- Research has revealed the presence of opportunistic molds, nontuberculous mycobacteria and other pathogens in hospital water (i.e. humidifiers, sinks and plumbing fixtures), which can expose patients to serious risk of infection
Required water monitoring adds time and labour to your process. But with ready-to-use wipes, the pre-work has already been done in a controlled and protected environment.
