BIOCAT CHEMICAL-FREE LIMESCALE PROTECTION SYSTEMS

BIOCAT limescale protection: The green alternative to chemical water treatment

Hard water leads to calcified pipes, frequent repairs, and higher energy bills. That's why it makes sense to invest in a limescale protection system. Instead of the common chemical water treatment systems that are environmentally harmful and resource-intensive, we recommend the green, economical BIOCAT systems that do not require the addition of salt or phosphates.

BIOCAT limescale protection systems are effective, economical, and environmentally friendly

Maintenance-free for five years

Regardless of water consumption, the systems are maintenance-free for five years, after which the catalyst granulate must be replaced. There is no need for assistance from technicians or service personnel during operation, and there is no need to refill or store operating materials.

Patented catalyst technology

WATERCryst systems are based on our patented catalyst technology, which ensures that the value of the entire drinking water system is maintained and meets technical and normative standards. This applies regardless of the scale of your project - and whether the installation is in single-family homes, housing associations, commercial or public buildings.

Limescale protection with high drinking water quality and energy efficiency

The cost-effective BIOCAT systems are suitable for industry, hotels, residential complexes, and apartment blocks, among others, where they protect installations and technology from limescale damage and ensure high drinking water quality and energy efficiency through natural limescale protection.

Preserving healthy limescale and natural flavor

BIOCAT limescale protection systems are characterized by the fact that they remove the bad properties of limescale from drinking water - while preserving the natural and healthy limescale content. In this way, BIOCAT systems ensure, that drinking water retains its good, natural flavor.

MODE OF OPERATION

Patented catalyst technology - inspired by nature's method

BIOCAT systems work with a patented catalyst technology inspired by biomineralization - nature's way of forming calcium crystals. The technology works via a catalyst granulate that, with its special surface, can form microscopic crystals from the limescale dissolved in the water. These crystals are constantly flushed out with water withdrawals, preventing limescale deposits from forming in drinking water installations, for example. 

 

WATERCryst delivers both economically and environmentally sustainable solutions

SUSTAINABILITY

WATERCryst works to promote the UN Sustainable Development Goals on environment and sustainability

At WATERCryst, we work every day to promote more sustainable consumption and production patterns - which is an important part of the UN's adopted Sustainable Development Goals. Specifically, with our BIOCAT limescale protection system, we make it possible to replace installations that discharge harmful substances directly into the environment with chemical-free and more sustainable installations. The wastewater from a BIOCAT system is clean drinking water and contains no salt or other chemicals. BIOCAT systems are therefore the environmentally friendly alternative to other water treatment systems on the market. 

Effective limescale protection reduces energy consumption

Limescale protection is good for the climate because limescale build-up in pipes and on heat exchangers reduces heat transfer capacity - which hurts the CO2 balance of a building. Even a 6 mm thick layer of limescale leads to an additional energy cost of 50%. Effective limescale protection with a BIOCAT system prevents heat loss, saves energy, and thus has a significant positive effect on the CO2 balance.

CASES

HYGIENE

Clean and chemical-free drinking water for everyone

Limescale deposits create a biofilm that provides a breeding ground for bacteria and promotes legionella growth, among others. With BIOCAT, the drinking water system is effectively protected against limescale - and the integration of chemical-free limescale protection helps to maintain drinking water hygiene and good drinking water quality.

Always clean drinking water for everyone

BIOCAT limescale protection systems ensure compliance with the Drinking Water Ordinance and the minimization requirement so that drinking water is pathogen-free, clean, and fit to drink always. The certification company DVGW Cert GmbH ensures that each system fulfills all legal and normative requirements in all essential respects - and that they always remain compliant.

BIOCAT systems fulfill all legal requirements:

  • Drinking Water Ordinance
  • Pressure Equipment Directive
  • Machinery Directive
  • Low Voltage and EMC Directive
  • At least compliance with generally recognized technical rules and standards
  • Certified solutions

The certification program for issuing a DVGW-type examination certificate for lime protection systems according to DIN 1988-200 includes several essential requirements and tests in terms of performance, technical safety, documentation, and continuous quality control, among other things.

CAPACITIES

Scalable limescale protection solutions - from single-family homes to industry and housing associations

BIOCAT limescale protection systems are available in various sizes with different capacities. From the smallest systems suitable for single-family homes up to the largest systems that can cover the needs of industry and entire housing associations.

When a large-scale solution is needed for a holiday park with a water park, for example, the systems can be connected in series for virtually infinite capacity - without the need for huge amounts of salt.

 

Hardness is defined as the total dissolved calcium and magnesium content of the water - and is dependent on the type of water in the subsoil where each waterworks extracts water.

In general, the water is hardest on Zealand, Falster, Lolland, Møn and Funen. Jutland has the most soft and medium-hard water, but there are also areas where the water is hard in the western part of Denmark.

 

High calcium content in the water can lead to calcified pipes, frequent repairs to household appliances, extra cleaning and higher heating bills.

 

Biomineralization is the process by which living organisms produce their inorganic components such as shells, tooth enamel and bones. Several biominerals are known, of which calcium carbonate (CaCO3) is the most common. It is found in seashells - and is one of the building blocks of the patented WATERCryst catalyst technology. 

A 550-million-year-old method

Fossil evidence shows that organisms that use biomineralization to form skeletons, for example, have existed in the oceans for at least 550 million years. In other words: BIOCAT plants utilize a highly proven and successful process.

 

Taste is subjective, but the calcium in drinking water helps to give it a natural flavour. When cooking or brewing coffee, the minerals in the lime are also essential flavour carriers. Many people believe that removing the lime gives the water a soapy or flat flavor.

A "lime thermal barrier" is an insulating layer of lime on heat exchangers and pipes. The layer is formed by highly calcareous water. The "lime heat barrier" inhibits the heat transfer from the heat exchanger to the drinking water. This creates additional costs due to higher electricity demand, faster wear, and tear, etc.

 

Calcium, which is primarily made up of minerals such as calcium carbonate, is especially important for building teeth and bones. Calcium is also important for a number of other bodily processes, and it's a good idea to include calcium-rich foods in your diet and maintain calcium in your drinking water.

 

To avoid legionella growth in drinking water installations, make sure that the temperature in the hot water tank and/or drinking water tank is always kept at 60°C or higher. Effective limescale protection is essential for this to be possible.

BIOCAT lime protection systems require no maintenance. Every five years, the granulate in the system must be replaced. This is done by an authorized plumber. No salt or other chemicals and operating materials should be added to the system.

 

When lime changes its properties, it means that the lime loses its ability to adhere to surfaces and form deposits.

You can't avoid cleaning altogether - but BIOCAT makes it easier. When calcareous drinking water evaporates, minerals are always left behind, partly in the form of annoying stains. Clean and maintain your surfaces regularly and avoid white spots by wiping away water droplets before the water evaporates. Avoid using microfiber cloths, steel sponges and harsh abrasives that can roughen the surface coating. 

If there are limescale stains due to evaporation, use a gentle, natural household cleaner such as lemon essence.

BIOCAT systems are chemical-free because the process in a BIOCAT system works without the addition of salt and phosphates.

The great advantage of chemical-free water treatment is that the wastewater from a BIOCAT system is completely clean drinking water - a BIOCAT system does not release any harmful substances into the environment. A side benefit of chemical-free water treatment is that much less rinse water is required than with other water treatment methods.
