Ultrapure Water (UPW) is a very important part of the pharmaceutical industry, as it has such a high purity level of around 18.2 MΩ cm resistivity, which is perfect for removing ions, organic matter, bacteria and particulate matter. All of this can reduce the quality of medication and turn it into something that can be potentially catastrophic to patients' health.

It’s mainly used for drug manufacturing, as it can sanitise materials and equipment so everything is kept clean and away from any danger. This improves healthcare and makes it safer for patients by reducing contamination risks. It also improves the stability of therapeutic products for patients who need them to function properly.


This guide will explore how ultrapure water is used in pharmaceuticals and why it’s essential for keeping patients protected while improving their healthcare. Continue reading to learn more.


How Pharmaceutical Industries Improve Healthcare

Safety of Injectables

UPW is used to produce water for injection, the required solvent for injectable medications like vaccines for infectious diseases. These types of medications are used across the world, so it’s crucial that they’re made to be safe to use since they get injected into  the skin and blood flow of patients. This ensures that they are free from endotoxins, microbes and chemical impurities that could cause sepsis or fatal adverse reactions. 


Product Efficacy and Stability

When UPW is used, it can remove ionic and organic contaminants as it prevents chemical interactions that could degrade Active Pharmaceutical Ingredients (APIs). This ensures medications remain stable and effective throughout their existence to prevent wasted medication, all while ensuring patient treatment is always safe to administer.


Preventing Contamination

Small contaminants are dangerous for medications, as they can interfere with how cells grow or cause a patient's body to have a bad reaction. Those within the industry can use UPW to help scientists make sure the environment stays clean and steady so that nothing ruins the medicine. This step is crucial for keeping the treatment safe and making sure it works exactly the way it should for the person taking it.


Sterilisation of Medical Devices

The integration of UPW in the pharmaceutical industry helps to generate clean steam for autoclaving. This ensures that surgical instruments and complex medical equipment are stripped of microscopic bio-burden without the risk of chemical residue. This minimises the transmission of pathogens and significantly reduces hospital infections that can occur from using products that have been contaminated. You can improve the integrity of the medical tools and the lives of the patients they serve.


Accurate Diagnostics

When new medicines are created and tested, scientists must use UPW to ensure their experiments are perfect in order for them to function as intended. This water is so clean that it has been stripped of every impurity that could interfere with testing equipment, making sure that the whole process is carefully constructed. When researchers prepare liquid samples for analysis, even the smallest change can create fake results called ghost peaks on their digital charts. This can ruin the final product of medication, leading to adverse effects on patients.


Formulation of Sensitive Topical Products

When companies make sensitive products like face creams or eye drops, they must use UPW to ensure it’s as safe as possible. Regular water contains tiny minerals and invisible bacteria that can easily irritate your skin or cause painful infections in your eyes. Manufacturers can remove those hidden impurities so the final product is gentle and effective. This high standard of purity protects your health and helps the medicine work exactly as it should without any nasty side effects.


What Technology is Used for UPW?

Continuous Electrodeionization (CEDI)

CEDI is the leading technology for UPW production. Used by water management companies like Xylem, it can replace chemical-based ion exchange with an electrochemical process. This can help to remove any impurities, including carbon dioxide, that can ruin medication. CEDI is a continuous, low-energy-consuming process and avoids the need for chemical regenerants, perfect for cost savings.


Ultraviolet (UV)

UV light can disrupt the DNA of microorganisms to prevent them from growing any bigger, while specific UV wavelengths can break down trace organisms. It helps manufacturers get more protection when making medication, as the water can stay at a consistent quality that will support regulatory compliance.


The pharmaceutical industry couldn’t survive without UPW. It’s the necessary component needed to ensure that all medication is safe to use, as it helps to sterilise machinery used by manufacturers and prevent any contamination from occurring. Without UPW, patients will receive inadequate care, as the medication they take could harm them or give them adverse effects. It’s crucial that companies within the industry keep their patients safe at all times to avoid any legal action from being taken against them.

The Curious World of Competitive Niche Hobbies

There are people who train ferrets to run through drainpipes, others who iron shirts on mountain tops, and at least one society in Cumbria dedicated to racing wheelbarrows in full Edwardian dress.

Britain has long had a reputation for eccentric pastimes, but many of these niche hobbies are far more serious, and far more competitive, than they first appear.


From toe wrestling to conker championships, welcome to the quietly intense world of niche hobby competitions, where pride, planning, and decades-old rivalries are very much in play.


From Oddity to Obsession

What might look like a bit of harmless fun at the village fête often hides a fierce undercurrent of strategy and commitment.


Take the World Toe Wrestling Championships, held each summer in Derbyshire. Established in 1976, the sport involves two barefoot opponents locking toes and trying to pin each other’s foot down. Matches are officiated. Spectators gather. There are title holders. Training is involved.

Then there is the World Pea Shooting Championship, hosted annually in Witcham, Cambridgeshire. Competitors use laser-guided blowpipes to shoot dried peas at a target board. The record to beat is three perfect shots. The youngest entrant on record was just four years old. The oldest? In his nineties.


“It looks silly from the outside, but there’s real skill involved,” says Norman Hartley, who has competed in the event since 1994. “You have to factor in wind speed, moisture in the peas, and keep your aim steady. It’s not just puff and pray.”

It’s almost like being in on a joke the rest of the world hasn’t clocked yet. But you also get quite good at it.

Why We Love the Weird

Sociologists suggest that niche hobbies, especially competitive ones, satisfy a deep need for identity, ritual, and community. In a world that often feels chaotic, small traditions offer structure and shared purpose.


“There’s something very human about inventing a new way to compete,” says Dr Elaine Keating, a behavioural psychologist at Leeds Beckett University. “Niche hobbies often start as a joke or tradition, but over time they become a point of pride. And when you’re the best in the world at something — even if it’s underwater knitting — that title still means something.”


In many cases, these hobbies have decades of history. Some, like cheese rolling at Cooper’s Hill in Gloucestershire, have origins dating back to pagan festivals. Others were started on a whim and simply stuck. The Extreme Ironing Bureau, founded in Leicester in 1997, was initially a satirical art piece. It soon developed a following, with people ironing in forests, on mountains, and mid-skydiving jumps.


Even new hobbies are finding their moment. The rise of social media has introduced global audiences to competitions such as spoon balancing, speed cubing, competitive duck herding, and air guitar battles, all of which now boast global events, livestreams, and sponsorship deals.


A Bit of Britishness

Many of these hobbies reflect something quietly British: a love of the underdog, the eccentric, and the proudly impractical.


The World Stone Skimming Championships, held on Easdale Island in Scotland, welcomes competitors from around the world each September. To qualify, the stone must skip at least twice across the water. Skimming experts bring specially chosen slate discs, sometimes wrapped in chamois leather for grip. Officials measure every bounce with tape and telescope.


The British Lawnmower Racing Association, meanwhile, oversees dozens of events each year, including endurance races. Competitors remove the cutting blades, kit themselves out in protective gear, and race around muddy fields at speeds of up to 50 mph.

The prize? Usually a trophy, sometimes a pint, always bragging rights.


What Drives People?

One constant across these competitions is a strong sense of belonging.


You come for the novelty, but you stay for the people,” says Kat McGill, a champion in the UK Rock Paper Scissors League. “There’s a shared absurdity. It’s almost like being in on a joke the rest of the world hasn’t clocked yet. But you also get quite good at it, and then you want to win.”


Many hobbyists also point out that these events are deeply inclusive. Unlike mainstream sports, niche competitions often level the playing field, allowing people of all ages and backgrounds to take part. In many cases, newcomers are welcomed with open arms and a set of surprisingly detailed rules.


More Than a Laugh

It is easy to dismiss niche hobbyists as eccentric or unserious. But to those who compete, these events are more than a weekend lark.


They are social lifelines, creative outlets, or reminders that joy can be found in the unlikeliest of places. In an era dominated by screens and scrolling, getting together for a bog snorkelling championship or a black pudding toss is, perhaps, more important than it sounds.


And as long as there are people willing to balance eggs, race snails, or build tiny vegetable cars, the spirit of niche British competitiveness is likely to keep rolling.

Quite literally, in the case of the cheese.
