Our simple UV flow-through disinfection systems use UV light at 254nm which has a strong bactericidal action as it damages DNA and RNA polymerase at low doses preventing replication; higher doses are biocidal. The systems are maintenance-free except for the lamp replacement and the water only contacts the quartz sleeve surrounding the lamp which is minimizing contamination.

Our dual-wavelength UV disinfection systems use also UV light at 185nm which has a strong oxidising action breaking down large organic molecules into carbon dioxide. These components can be removed downstream by our high purity ion exchangers. The systems are also maintenance-free except for the lamp replacement and the water only contacts the quartz sleeve surrounding the lamp which is minimizing contamination.

UV immersion systems were specially developed for the chemical-free disinfection of water in storage tanks using UV radiation. The systems can be used in closed tanks with static and strongly fluctuating filling levels.

The UV system irradiates the water and the tank walls above and below the water level with UV-C radiation, so that no biofilm can develop and the water is permanently disinfected. This not only optimally disinfects the water, but also prevents rapid renewed contamination of the water from causing problems; these devices are therefore a real in-situ solution.

It disinfects the entire interior of the tank (liquid, gas space and tank wall surfaces) and also forms an effective barrier against contamination via the tank ventilation.

In this way, a chemical-free solution ensures better efficiency than chemicals, because no resistance to UV radiation can develop without the side effects of the disinfectant having to be accepted.

Sediment filters are commonly nominal filters in 5", 10" or 20" from 10 to 1µm which remove visible particulate matter, and any particles of dirt, sand, dust, and debris that can be caught by its micron-rated capacity. Sediment filters also remove turbidity from water. Turbidity is the cloudiness caused in water by the heavy presence of suspended solids. This causes water to turn yellow, orange, or brown.

Sediment filters are most effective when serving as prefilters for other filtration systems. This is why sediment filtration very often works in conjunction with other filtration methods, like reverse osmosis.

Activated carbon is used because of its reducing effect against organic, inorganic and harmful substances. It reduces flavours and odours as well as chlorine, pesticides (Lindan, DDT) and trihalomethanes (THMs). The fabrics are adsorbed from the large surface area of the activated carbon. The combination with a sediment filter is the perfect choice to protect downstream reverse osmosis membranes.

Lime can clog and even totally block RO membranes. The level of water hardness depends on the calcium and magnesium ions dissolved in the water. Crystallization leads to build-ups of sediment. To avoid this, long-chain polyphosphates prevent the nucleation and crystallization processes that lead to deposits. This method makes it possible to completely stabilize the carbonate hardness of drinking water if the water hardness is lower than 10°dH so that no water softener is needed.

Sterile filters are used to remove particulate and microbial contamination from water. Filtering through a 0.2 micron pore size is considered necessary to generate a sterile filtrate.

All sterile filters are designed, developed and manufactured in accordance with a Quality Management System approved by an accredited registering body.

Ultrafiltration is one membrane filtration process that serves as a barrier to separate harmful bacteria, viruses, and other contaminants from clean water by means of a 0.05 micron membrane. Suspended particles that are too large to pass through the membrane stick to the outer membrane surface. Only fresh water and dissolved minerals pass through.

Varios optional level sensors are available to communicate with the water purification system.

Advanced vent filters with or without CO2 Adsorber protecting your stored water against airborne contaminants.

A sterile overflow protects your stored water from bacteriological contamination from the drain.

UV sanitization module prevents the growth and proliferation of bacteria.

NEPTEC pumps are supplied as a complete preassembled system mounted on a base frame. The only task left is to connect the pipes and the power supply

We are using highly intelligent booster systems which are capable of controlling up to four speed-controlled pumps in cascade. It has only two buttons for complete control of the system. Alternatively, you can use Grundfos GO Remote for setup and control.

The speed-controlled pumps are perfectly controlled and adjusted by the PI controller to deliver the correct pressure at the required flow.

Grundfos pumps are known for their reliability and long life. The PI controller is protected inside the pump and this has proven to be a very reliable solution.

All pumps that have an outlet-pressure sensor connected are capable of taking control of the entire booster system. This means that the system will continue to operate as a booster system even if one or more of the pumps or sensors are unavailable. Compared to systems with only one sensor, this makes our pump station an extremely reliable solution.

The pump stations ensure low energy consumption through speed-controlled pumps, automatic cascade control of the pumps and highly efficient low-flow operation. The highly efficient motors and pumps also contribute to the overall high efficiency.

Pump alternation ensures that the operating hours are distributed evenly on the pumps over time.

Dry-running protection is very important as dry running may damage the bearings and shaft seals.
