How to make water drinkable?

April 8, 2024

There are various ways to purify water and make it drinkable. Water filters are one of the simplest and most cost-effective solutions, but not all filters are the same. In this article, we want to explain the differences between water filters and filter quality, when water is really drinkable and which filter methods are suitable for obtaining pure drinking water.

Water purification involves removing contaminants to make water safe to drink. Let’s explore the key methods and the scenarios they’re best suited for.

1. Mechanical Filters

These filters physically block contaminants like dirt, sediments, and microorganisms using a fine mesh or membrane.

Examples: Portable water filter bottles, pump filters, gravity-fed systems.
Pros:
- Easy to use and portable.
- Effective against bacteria and protozoa.
Cons:
- Doesn’t remove viruses or dissolved chemicals like pesticides.
Best for: Removing dirt and pathogens from relatively clean-looking water sources, like mountain streams.

2. Activated Carbon Filters

Activated carbon removes impurities by adsorbing chemicals, odours, and tastes.

Examples: Water filter jugs, inline filters for camper vans, or combination systems.

Pros:
Reduces chemicals (e.g., chlorine, pesticides) and improves taste.
Easy to pair with mechanical filters.
Cons:
Ineffective against germs and other pathogens.
Best for:
Filtering tap water or improving rainwater quality.

3. Ultraviolet (UV) Purification

UV light kills bacteria, viruses, and protozoa by disrupting their DNA, rendering them harmless.

Examples:
UV pens, UV purifiers built into water bottles.
Pros:
Highly effective against pathogens.
Lightweight and easy to use.
Cons:
Doesn’t remove sediment, chemicals, or taste.
Requires batteries or solar charging.
Best for:
Treating clear water from taps, tanks, or streams.

4. Chemical Treatment

Using purification tablets or drops, these methods kill pathogens chemically (e.g., chlorine dioxide or iodine).

Pros:
Lightweight and compact.
Effective against bacteria, viruses, and protozoa.
Cons:
Leaves a chemical taste in water.
Takes time (up to 4 hours for Giardia).
Best for:
Emergency purification in remote areas.

5. Boiling

Boiling water for at least 1 minute (or longer at high altitudes) kills pathogens effectively.

Pros:
Simple and highly effective.
No need for additional equipment.
Cons:
Time-consuming and fuel-intensive.
Doesn’t remove sediments or chemicals.
Best for:
Remote camping with access to a camp stove or fire.

Key Points for Australian Campers

Rainwater: Common in Australian campsites, but may contain bird droppings or other contaminants. Filter and purify before drinking.
Desert Areas: Water sources may be scarce. Carry enough water.
Freshwater Streams and Lakes: Always assume these contain pathogens and treat accordingly before drinking.
Coastal Areas: Avoid using saltwater unless you have a desalination system.

Pro Tips for Safe Water Use

Test Your Gear: Practice using your filter or purifier at home to ensure you’re confident with it.
Inspect Filters: Replace or clean filters as recommended.
Stay Hydrated: Safe water is essential—plan your route with water availability in mind.

Final Thoughts

Purifying water doesn’t have to be complicated, and with the right tools, you can enjoy clean, safe water anywhere in Australia. Whether you’re camping under the stars in the Outback or exploring the lush coastal trails, understanding the differences in purification methods will keep your adventures worry-free. Stay prepared, stay hydrated, and enjoy everything Australia has to offer!

Why Water Treatment is Essential

Even if your tank is full of clean water at the start of your trip, prolonged storage, exposure to high temperatures, and stagnant conditions can compromise its quality. Without proper treatment, the water in your tank may develop:

Foul smells or tastes from organic build-up.
Bacterial contamination, including pathogens like Legionella or E. coli.
Biofilm growth, a slimy layer that fosters bacteria inside your tank or pipes.

Adding to the challenge, refilling your tank from unknown sources at campsites or remote locations increases the risk of contamination from sediment, chemicals, or microbes.

Methods to Keep Water Fresh

There are three main approaches to treating water in your motorhome, each with its advantages and limitations:

1. Silver Ions

Silver ions are added to water to inhibit the growth of bacteria and algae, helping to maintain water freshness for up to six months.

Advantages:

Long-lasting protection against microbial growth.
Minimal effort required after initial application.

Disadvantages:

Water treated with silver ions is no longer classified as drinking water according to Australian standards. It should not be shared with others or used for extended periods.
Environmental and consumer protection agencies recommend caution with prolonged use due to health concerns.

Best Use Case:
Silver ion treatment is suitable for private, short-term use in regions where water is unlikely to be consumed directly or shared.

2. Chlorine or Chlorine Dioxide

Chlorine is a powerful disinfectant that eliminates harmful pathogens in water, including bacteria, viruses, and algae.

Advantages:

Effective against a wide range of waterborne contaminants.
A practical solution for emergency treatment or poor-quality water sources.

Disadvantages:

Alters the water’s taste and smell, making it less palatable.
Requires careful monitoring of chlorine levels (typically 0.1–0.2 mg/L) to avoid overuse.

Best Use Case:
Chlorine is ideal for emergency treatment, particularly when using water from unknown or potentially contaminated sources.

3. Water Filters

Water filters physically remove impurities and contaminants from water, offering a chemical-free solution to maintaining water quality.

Advantages:

Removes a wide range of contaminants, including sediment, microplastics, pesticides, and bacteria.
Improves taste and smell without the use of chemicals.
Versatile options for both pre-tank and post-tank filtration.

Disadvantages:

Filter cartridges should be replaced every 4–6 months to ensure effectiveness.

Best Use Case:
Water filters are the most versatile and environmentally friendly solution, ideal for both short and long trips.

Choosing the Right Water Filter System

When it comes to filtering water in your RV, caravan, or boat, Alb Filter offers flexible options tailored to Australian travelers:

Pre-Tank Filtration: Filters water before it enters your tank, preventing contaminants from ever reaching your storage system. Ideal for frequent refills at campsites or outdoor taps.
Post-Tank Filtration: Filters water directly before use, ensuring clean water at the tap even if the tank has been sitting for extended periods. Essential for warm climates or large tanks.
Fusion Systems: Combines multiple filtration stages (e.g., activated carbon and hollow fiber membranes) for comprehensive treatment of sediment, chemicals, and pathogens.

Tips for Maintaining Water Quality

Regular Cleaning: Clean and disinfect your water tank and pipes after every trip or every few months if continuously in use. This prevents biofilm buildup and reduces contamination risks.
Conserve Water: Use low-flow taps and mindful consumption to extend your water supply, particularly in remote areas.
Install a Backup Filter: Consider adding a secondary filter system near your water outlet for extra protection against bacteria and residual contaminants.

Final Thoughts

Safe, fresh drinking water is non-negotiable for anyone traveling in an RV, caravan, camper, or boat. While silver ions and chlorine offer temporary solutions, water filters provide the most reliable, sustainable, and user-friendly option. Alb Filter’s advanced filtration systems are sure to give you peace of mind by delivering premium water quality on your next outdoor adventure!
