Bacteria in water are a risk that often goes undetected in water treatment systems, cooling towers, and air conditioning. Bacterial contamination can cause tastes and smells in processed water and may also raise severe health risks. For example, Legionnaires’ disease is a form of pneumonia that is caused by the legionella bacterium. This can be found in aquatic systems and thrives in temperatures between 25°C and 45°C.
Legionella in water is commonly found in large air conditioning systems and industrial cooling systems. Researchers found that of the cooling towers tested for the presence of legionella, between 40 to 60% were contaminated. In France, it was found that the legionella bacteria travelled up to 6 km’s through the air from a large contaminated open circuit cooling tower. Outbreaks of Legionnaires’disease are a worldwide problem. After the first outbreak in Philadelphia (USA) in 1976, where 34 people died, outbreaks in the Netherlands (in 1999) and Spain (in 2001) have occurred. Therefore, needless to say, legionella prevention is of the highest priority.
Traditionally, the problem of legionella in water is addressed by adding chlorine to the water. However, not only does this leave a bad taste, it also leads to the formation of carcinogenic compounds. By reducing phosphate levels in water to below 1 ppb, BiAqua Phosphate Removal Technology (PRT™) successfully inhibits bacterial growth. As phosphate is a key nutrient for bacteria such as legionella, BiAqua PRT™ is the ideal bio-based solution for legionella prevention.
BiAqua PRT™ can be retrofitted into standard water treatment systems, but can also be supplied as a stand-alone solution. Therefore, we provide a versatile solution that is not only cost-effective but also very sustainable. Contact us today and learn how you can prevent legionella problems with BiAqua PRT™.
