Water Purification Systems

Water Purification Systems for Laboratories

The precision of the results in any laboratory depends on the quality of the reagents used, and the foundation of modern analytical processes is crystal clear water. For this purpose, the DANLAB store supplies advanced reverse osmosis modules, such as the RO D100 and RO D200 models, which guarantee the highest standards of chemical and microbiological purity. At the heart of these devices is a high-quality osmotic membrane, which acts as an extremely dense sieve.

These systems effectively eliminate a wide range of harmful substances from liquids, such as:

• dissolved salt ions,
• hazardous heavy metals,
• pathogenic microorganisms,
• nuisance organic pollutants,
• bacteria and viruses.

Choosing the right treatment technology, preceded by feed water analysis, maximizes the efficiency of the entire system. Properly selected filtration is not only demineralized water with excellent parameters, but also effective protection of laboratory equipment against limescale deposits. As a result, the expensive equipment retains full efficiency and measurement accuracy for many years of intensive use.

Demineralizers of the HLP, R, Technical and Spring series

The HLP, R, Technical and Spring systems set modern standards in laboratory water treatment. Thanks to the use of ALIA technology and the ion exchange process, the specialized resin effectively removes calcium, magnesium and sodium ions, which ensures parameters in accordance with stringent analytical standards.

The choice of device depends on the specifics of the work being carried out. The Technical and Spring series support routine tasks, while the HLP and R are designed for advanced research. DANLAB's offer includes the UF HLP module at an attractive price. The key to maintaining the highest quality is the systematic regeneration of the bed.

The advantages of the demineralizers we offer are:

• extremely low conductivity of the water obtained,
• effective elimination of ionic contaminants,
• full compliance with quality standards,
• precise adjustment to the test profile,
• low operating costs and high efficiency,
• long-term reliability of the entire system.

Basic deionizers and Ultra after-cleaning systems

The Basic and Ultra systems are the foundation of modern water treatment, ensuring the highest precision in the removal of harmful substances. Thanks to the use of advanced technology, these devices effectively eliminate contaminants that could negatively affect the course of research processes:

• troublesome nitrates,
• phosphates,
• ammonium ions,
• toxic lead,

A key element of the structure is an efficient activated carbon block, precisely absorbing organic pollutants. Continuous monitoring of parameters such as conductivity and TDS guarantees full control over the quality of the liquid and minimizes the risk of analytical errors.

In places with limited space, compact under-sink filters are perfect, combining space savings with high work efficiency. However, it should be remembered that the condition for their reliability is the systematic replacement of cartridges and regular, professional service of the equipment, which allows to obtain repeatable and reliable test results.

Laboratory Distillers for Pure Water Production

Laboratory distillers provide crystal clear water, without which the proper operation of autoclaves would be impossible. Although these devices precisely eliminate minerals and organic compounds, hard feed water remains their biggest enemy. The calcium and magnesium salts contained in it quickly transform into a nuisance stone, which destroys heaters and drastically shortens the life of the apparatus.

To protect delicate components, it is worth pre-softening the water. Modern descaling systems effectively neutralize minerals, which, combined with regular maintenance, provides the following benefits:

• effective neutralization of harmful substances,
• Extend the life of your equipment by up to half
• protection against sudden failures of pressure systems,
• ensuring full repeatability of test results,
• Reduce the risk of costly repairs and downtime.

Industrial treatment plants from 100 to 1000 dm³/h

Modern industrial stations - with a capacity of up to 1000 dm³/h - effectively treat water from both the network and their own intakes. The purification process is based on aeration, which instantly oxidizes iron ions, allowing for easy filtering of the resulting sludge. DANLAB offers a professional 20-inch iron deferring cartridge at an affordable price.

The use of advanced treatment systems provides comprehensive protection for:

• effective elimination of iron,
• removal of manganese and hydrogen sulphide,
• protection of the installation against corrosion,
• prevention of congestion,
• automatic regeneration of the bed.

The design of the devices is based on durable tanks and precise pumps, and the whole thing is supervised by an advanced microprocessor. The system automatically manages the operation of the device, which guarantees stability even during intensive use. To ensure the longevity of the fittings, professional installation and systematic service are crucial.

Choosing a model that is precisely tailored to the parameters of a given shot is the best way to achieve maximum efficiency!

Water purity classes according to PN-EN ISO 3696:1999

According to the PN-EN ISO 3696:1999 standard, the classification of laboratory water defines three degrees of purity, which are crucial for the reproducibility of results. The choice of grade depends on the specifics of the tests and the required precision.

Modern treatment systems combine stringent standards with advanced treatment technologies:

• the first degree of purity - it is dedicated to ultratrace tests and HPLC chromatography,
• the second degree of purity - it is optimal for AAS techniques and the preparation of precise reagents,
• the third degree of cleanliness - is used in routine work and to power basic equipment,
• UV lamps are used to eliminate microorganisms and reduce organic carbon TOC,
• microfiltration with the use of membranes with a pore of 0.22 μm captures the finest suspensions,
• Mineralization precisely corrects the ionic composition to achieve ideal liquid parameters.

UV lamp and microfiltration in purification systems

The water purification process is crowned with UV sterilization, which effectively neutralizes bacteria by damaging their DNA structure without interfering with the chemical composition of the liquid. The entire system is additionally protected by microfiltration, which prevents the accumulation of deposits. DANLAB's offer includes dedicated polypropylene cartridges: a model with an accuracy of 1 μm and a variant of 20 μm.

Advanced treatment systems use the following solutions:

• UV heaters - destroy the genetic material of bacteria,
• precision polypropylene cartridges of various densities,
• capillary membranes - separate the finest dusts,
• ozonators - remove chlorine that destroys osmotic membranes,
• Tubular filters - extend the life of the apparatus.

The use of an ozonator allows not only for disinfection, but also protects sensitive osmotic membranes from the destructive effects of chlorine. To minimize operating costs and ensure stable operation of the equipment, it is worth choosing tubular filters, which effectively protect the system from premature wear and guarantee its long-term efficiency.
