Sustainability in water treatment is often discussed in terms of what happens at the point of use. But an equally important question is what happens 𝗯𝗲𝗳𝗼𝗿𝗲 𝘁𝗵𝗲 𝘁𝗿𝗲𝗮𝘁𝗺𝗲𝗻𝘁 𝗰𝗵𝗲𝗺𝗶𝗰𝗮𝗹 𝗲𝘃𝗲𝗻 𝗮𝗿𝗿𝗶𝘃𝗲𝘀 𝗼𝗻 𝘀𝗶𝘁𝗲.

Traditionally, hydrogen peroxide is produced in large centralized plants and then transported, stored, and handled — a process with a significant environmental footprint.

HPNow was founded on a simple idea: what if hydrogen peroxide didn’t need to be shipped at all? Instead, our technology enables 𝗼𝗻-𝘀𝗶𝘁𝗲 𝗴𝗲𝗻𝗲𝗿𝗮𝘁𝗶𝗼𝗻 𝗼𝗳 𝗵𝘆𝗱𝗿𝗼𝗴𝗲𝗻 𝗽𝗲𝗿𝗼𝘅𝗶𝗱𝗲 𝘂𝘀𝗶𝗻𝗴 𝗼𝗻𝗹𝘆 𝘄𝗮𝘁𝗲𝗿, 𝗲𝗹𝗲𝗰𝘁𝗿𝗶𝗰𝗶𝘁𝘆, 𝗮𝗻𝗱 𝗮𝗶𝗿. This eliminates transportation, packaging, and handling, reducing both emissions and operational risk.

The result is a fundamentally different model — 𝗱𝗲𝗰𝗲𝗻𝘁𝗿𝗮𝗹𝗶𝘇𝗲𝗱, 𝗰𝗵𝗲𝗺𝗶𝗰𝗮𝗹-𝗶𝗻𝗽𝘂𝘁-𝗳𝗿𝗲𝗲, 𝗮𝗻𝗱 𝗱𝗲𝘀𝗶𝗴𝗻𝗲𝗱 𝗳𝗼𝗿 𝗰𝗶𝗿𝗰𝘂𝗹𝗮𝗿 𝘄𝗮𝘁𝗲𝗿 𝘀𝘆𝘀𝘁𝗲𝗺𝘀. HPNow systems can offset 𝘂𝗽 𝘁𝗼 3 𝘁𝗼𝗻𝘀 𝗼𝗳 𝗖𝗢₂ 𝗲𝗾𝘂𝗶𝘃𝗮𝗹𝗲𝗻𝘁 𝗽𝗲𝗿 𝘁𝗼𝗻 𝗼𝗳 𝗵𝘆𝗱𝗿𝗼𝗴𝗲𝗻 𝗽𝗲𝗿𝗼𝘅𝗶𝗱𝗲 compared with conventional supply chains, and because peroxide breaks down into 𝗰𝗹𝗲𝗮𝗻 𝘄𝗮𝘁𝗲𝗿 𝗮𝗻𝗱 𝗼𝘅𝘆𝗴𝗲𝗻, it leaves no harmful residues.

For companies reporting on 𝗦𝗰𝗼𝗽𝗲 3 𝗲𝗺𝗶𝘀𝘀𝗶𝗼𝗻𝘀, 𝗴𝗹𝗼𝗯𝗮𝗹 𝗚𝗥𝗜 𝘄𝗮𝘁𝗲𝗿 𝘀𝘁𝗲𝘄𝗮𝗿𝗱𝘀𝗵𝗶𝗽, 𝗮𝗻𝗱 𝗹𝗼𝗰𝗮𝗹 𝘄𝗮𝘁𝗲𝗿 𝗱𝗶𝘀𝗰𝗵𝗮𝗿𝗴𝗲 𝗹𝗶𝗺𝗶𝘁𝘀, HPNow reduces reported impacts while simplifying compliance.

At HPNow, we believe the future of water treatment is not only effective — it is 𝗹𝗼𝗰𝗮𝗹, 𝗰𝗶𝗿𝗰𝘂𝗹𝗮𝗿, 𝗮𝗻𝗱 𝘀𝘂𝘀𝘁𝗮𝗶𝗻𝗮𝗯𝗹𝗲 𝗯𝘆 𝗱𝗲𝘀𝗶𝗴𝗻.

The European Union has taken a major step in tightening water quality standards, with new limits on PFAS in drinking water now officially in force, since January 12th, 2026. Often referred to as “forever chemicals,” PFAS are known for their persistence in the environment and their resistance to natural degradation. Their widespread historical use across multiple industries has made them a growing concern for both regulators and water providers.

The updated 𝗗𝗿𝗶𝗻𝗸𝗶𝗻𝗴 𝗪𝗮𝘁𝗲𝗿 𝗗𝗶𝗿𝗲𝗰𝘁𝗶𝘃𝗲¹ introduces strict thresholds for PFAS concentrations, placing new compliance responsibilities on water utilities and industrial water users alike. What makes this development particularly significant is that 𝘗𝘍𝘈𝘚 𝘩𝘢𝘴 𝘦𝘧𝘧𝘦𝘤𝘵𝘪𝘷𝘦𝘭𝘺 𝘮𝘰𝘷𝘦𝘥 𝘧𝘳𝘰𝘮 𝘣𝘦𝘪𝘯𝘨 𝘢 𝘮𝘰𝘯𝘪𝘵𝘰𝘳𝘦𝘥 𝘤𝘰𝘯𝘵𝘢𝘮𝘪𝘯𝘢𝘯𝘵 𝘵𝘰 𝘰𝘯𝘦 𝘵𝘩𝘢𝘵 𝘳𝘦𝘲𝘶𝘪𝘳𝘦𝘴 𝘢𝘤𝘵𝘪𝘷𝘦 𝘢𝘯𝘥 𝘥𝘦𝘮𝘰𝘯𝘴𝘵𝘳𝘢𝘣𝘭𝘦 𝘵𝘳𝘦𝘢𝘵𝘮𝘦𝘯𝘵. This shift is expected to drive substantial investment into advanced water treatment technologies across Europe as organizations evaluate how to meet current limits and prepare for potentially even stricter requirements in the coming years.

Beyond regulatory compliance, this development reflects a broader shift in how water quality is approached. Treatment strategies are increasingly expected to address multiple contaminants simultaneously while supporting sustainability goals and operational efficiency. As a result, water treatment is no longer just about meeting minimum standards, but about building resilient and future-proof water management systems.

The article 𝘕𝘦𝘸 𝘌𝘜 𝘗𝘍𝘈𝘚 𝘓𝘪𝘮𝘪𝘵𝘴 𝘈𝘤𝘵𝘪𝘷𝘢𝘵𝘦 €3.6𝘉 𝘋𝘳𝘪𝘯𝘬𝘪𝘯𝘨 𝘞𝘢𝘵𝘦𝘳 𝘛𝘳𝘦𝘢𝘵𝘮𝘦𝘯𝘵 𝘖𝘱𝘱𝘰𝘳𝘵𝘶𝘯𝘪𝘵𝘺² provides a valuable overview of how these regulatory changes are shaping the water treatment landscape and what they mean for utilities and industrial operators moving forward. Check it out below.

At HPNow, advanced water treatment is at the core of our work, and we closely follow regulatory and technological developments around PFAS. If your organization is evaluating how evolving requirements may impact its water treatment strategy, we are happy to support the development of compliant, resilient and future-proof solutions.

𝗤: What kind of water does the onsite Peroxide UltraPure™ generator need to operate correctly?

The water supplied to the system plays an important role in how efficiently and reliably it performs. Since the system generates peroxide directly from water, air, and electricity — rather than dosing a pre-made chemical — the properties of the water matter.

We asked Rajath Sathyadev Rajmohan, our 𝗛𝗲𝗮𝗱 𝗼𝗳 𝗖𝗼𝗿𝗲 𝗥&𝗗 to break it down in practical terms.

Rajath's answer:
The Peroxide UltraPure™ system generates hydrogen peroxide in its purest form - this means that the quality of the incoming water plays an important role in ensuring stable, efficient operation.

In practice, the system is designed to operate with 𝘀𝘁𝗮𝗻𝗱𝗮𝗿𝗱 𝗽𝗼𝘁𝗮𝗯𝗹𝗲-𝗾𝘂𝗮𝗹𝗶𝘁𝘆 𝘄𝗮𝘁𝗲𝗿. Potable water suffices as our systems come equipped with filters that convert it into demineralized water. Excessively high levels of hardness, iron, manganese, or suspended solids can impact long-term performance, which is why basic pre-filtration is sometimes required.

The goal is consistency: clean, stable input water helps ensure reliable peroxide generation, predictable concentrations, and low maintenance over time. Understanding water quality upfront allows systems to be configured correctly from day one — and helps users get the most out of onsite peroxide generation.

𝗢𝘇𝗼𝗻𝗲, 𝗰𝗵𝗹𝗼𝗿𝗶𝗻𝗲, 𝗵𝘆𝗱𝗿𝗼𝗴𝗲𝗻 𝗽𝗲𝗿𝗼𝘅𝗶𝗱𝗲… all very different substances. Yet they all try to do the same thing: treat water efficiently and tackle pathogens, which over time form biofilm — a slimy layer that can clog cooling systems, spread microbes, and generally become a nightmare.

With so many water treatment methods available, each comes with its own advantages and limitations. The same is true for oxidants like chlorine and hydrogen peroxide—not all solutions are created equal.

We’re hydrogen peroxide people, and we believe it’s the way to go for safe, effective water treatment. But we went a step further - we created 𝗣𝗲𝗿𝗼𝘅𝗶𝗱𝗲 𝗨𝗹𝘁𝗿𝗮𝗣𝘂𝗿𝗲™. It’s pure H₂O₂, no stabilizers, no additives.

At 𝗛𝘂𝗻𝘀𝗯𝗮𝗹𝗹𝗲 𝗚𝗿ø𝗻𝘁, a modern Danish greenhouse growing strawberries and blueberries, the team struggled with clogged drippers and uneven irrigation caused by biofilm and organic matter in their water. After installing HPNow's Peroxide UltraPure™ generator, the treated sections saw virtually no clogging, improved irrigation uniformity, and healthier plants throughout the season.

“We did a trial where we dosed Peroxide UltraPure™ in one section and could compare to a section which didn’t have the treatment. We could see a clear difference in how the drippers were kept clean with Peroxide UltraPure™, and plants
were healthier.” says Claus Hunsballe, Owner.

Drought conditions in England are predicted to persist into 2026, after the driest spring in 132 years and the hottest summer on record. Reservoir levels sit around just 63% of their seasonal average, and experts warn that without sustained rainfall a full recovery is far from certain¹. Helen Wakeham, chair of The National Drought Group (NDG) commented that a changing climate means we must prepare for more droughts and that water security is a 𝘯𝘢𝘵𝘪𝘰𝘯𝘢𝘭 𝘱𝘳𝘪𝘰𝘳𝘪𝘵𝘺.

For growers, this means water security is not just an operational concern—it’s a strategic risk. At HPNow, we’re focused on helping businesses adapt with solutions that make every drop work harder, while reducing reliance on chemical-heavy treatments.

Data centers are under pressure to cut emissions and improve ESG performance — but what about water treatment? Microbial biofilm clogs systems, reduces heat exchange, and typically requires chemicals that leave unwanted byproducts behind.

Hydrogen peroxide is a superior way to treat cooling water — but not all peroxide is created equal. Totes of peroxide often contain stabilizers that remain in your system as residue and eventually need to be removed. 𝗢𝗻-𝘀𝗶𝘁𝗲 𝗴𝗲𝗻𝗲𝗿𝗮𝘁𝗲𝗱 𝗽𝗲𝗿𝗼𝘅𝗶𝗱𝗲, by contrast, is produced at the point of use, of the highest purity and potency, and requires no stabilizers. It fights biofilm efficiently, keeping cooling systems clean and heat exchange at maximum.
