AORA - Mobile reverse osmosis system with hot water function, no water connection required

Aktivkohlefilter sind sehr effektiv beim Entfernen vieler chemischer Verunreinigungen aus Wasser, aber sie sind nicht besonders gut geeignet, um Nitrat (NO₃⁻) zu entfernen. Aktivkohle arbeitet hauptsächlich durch Adsorption, was bedeutet, dass sie Moleküle wie Chlor, Pestizide, Lösungsmittel und organische Verbindungen an ihrer Oberfläche bindet. Nitrate, die anorganische Ionen sind, werden jedoch nicht effizient von Aktivkohleadsorbiert.

Für die Entfernung von Nitrat aus Wasser gibt es andere Methoden, die effektiver sind:

1. Umkehrosmose: Diese Methode kann Nitrate sehr gut aus dem Wasser filtern. Dabei wird Wasser durch eine semipermeable Membran gepresst, die die meisten gelösten Salze und Schadstoffe, einschließlich Nitraten, zurückhält.

2. Ionenaustauscherharze: Diese Harze tauschen Ionen wie Nitrate gegen weniger schädliche Ionen, meist Chloride oder Sulfate. Diese Methode ist weit verbreitet für die Entnitrifikation von Trinkwasser.

3. Destillation: Durch Erhitzen des Wassers und anschließendes Kondensieren des Dampfes können viele gelöste Substanzen, einschließlich Nitraten, entfernt werden.

Wenn du also Nitrat aus deinem Wasser entfernen möchtest, solltest du entweder eine Umkehrosmoseanlage oder ein Ionenaustauschsystem in Betracht ziehen. Ein Aktivkohlefilter ist hierfür nicht geeignet.

Reverse osmosis is a water treatment process based on the principle of selective permeability. It is a widely used method for desalinating water and removing impurities. Reverse osmosis is used in various applications, including drinking water treatment, seawater desalination, wastewater treatment and process water purification.

The basic principle of reverse osmosis is to force water through a semi-permeable membrane under high pressure. The membrane is designed to retain certain molecules and ions while allowing water molecules to pass through. This effectively removes salts, minerals, organic compounds, heavy metals and other impurities from the water.

The reverse osmosis process consists of several components. Firstly, the water to be treated is fed into a pre-filter to remove coarse impurities such as sediment, particles and rust. The water is then pumped into the reverse osmosis unit, where it flows through the semi-permeable membrane.

The high pressure generated by a pump forces the water to pass through the membrane. The membrane consists of a thin layer of semi-permeable material that is able to allow water molecules to pass through but retain larger dissolved substances. This frees the water from most impurities.

The purified water that has passed through the membrane is called permeate and can be used for various purposes, including drinking water, food processing or industrial processes. The water that has not passed through the membrane and contains the impurities is called concentrate and is usually disposed of or recycled back into the reverse osmosis process to optimise water consumption.

The performance of a reverse osmosis unit is influenced by various factors, including the pressure, the nature of the membrane, the temperature of the water and the type and concentration of impurities in the source water. To ensure the efficiency and durability of the system, it is important to carry out regular maintenance work, such as cleaning and replacing the membranes.

Reverse osmosis offers an effective method of water treatment, especially in areas with limited access to clean water or where high purity water is required. It is a proven process for desalinating seawater and removing impurities from various water sources. Continuous development of the technology has led to improved membranes and more efficient systems that enable cost-effective and sustainable water treatment.

The float may also need to be cleaned during cleaning to prevent algae from forming in the water tank.

Please always put the float back in the correct position when reassembling, i.e. the magnet must point towards the device to reactivate the pump signal. This should solve the problem in most cases.
