MDS

MULTI-CHEMICAL DOSING SYSTEM

MDS is a compact, automatic system designed for the production and dosign of multi-chemical products in aqueous solution for water treatment purposes, within the scope of use specified in these instructions.

MDS simultaneously doses two chemicals into the water inside the reactor. Generation is monitored by the HMI and can be adjusted by a flow meter with the main water flow.

The system includes three protections:

A protection for the 1st chemical component
A protection for the 2nd chemical component
A protection from the minimum flow reading of the dilution water meter

The generation of the solution occurs inside a reactor with external water flow to protect the reactor. Inside the reactor, the two reagents react with the dilution water at a concentration of approx. 2 g/l (2000 ppm).

LOTUS DISINFECTION SYSTEMS

SAFE DISINFECTION

LOTUS chlorine dioxide generators are the most effective solution for water disinfection in a variety of applications and in particular for the prevention of legionellosis in domestic hot and cold water systems.

The bacterium that causes legionellosis, Legionella, is able to adapt even to conditions that would be fatal to other organisms. Thanks to its high Redox potential, chlorine dioxide exerts a more powerful disinfectant action than other biocides against Legionella and all kinds of germs and contaminants such as viruses, bacteria, fungi and algae. The oxidation potential is higher than that of chlorine, for example, so fewer chemicals can be used. Potentially dangerous disinfection by-products are absent and it is proven to penetrate and degrade the Legionella habitat. The action of the chlorine dioxide is independent of the pH value of the water, is not aggressive towards pipes and has a longer-lasting and wider-ranging effect from the injection point.

Scientific tests have shown the effectiveness of the disinfectant action, with almost 100% killing of Legionella in just 30 minutes and elimination of the proliferation habitat. Safety is ensured by the atmospheric pressure production process, in which chlorine dioxide is never treated in its gaseous form but is produced by reacting two liquid precursors in a reaction chamber in only the amount needed at the time.

LOTUS AIR

LOTUS AIR is a pressure-less chlorine dioxide generator useful for those applications in which several injection points are required. Chlorine dioxide is produced from diluted base chemicals: acid-chlorite process by Hydrochloric Acid (HCl 9%) and Sodium Chlorite (NaClO₂ 7,5%).

Chlorine dioxide produced by LOTUS AIR is stocked into a tank and then dosed proportionally to the request. A multifunction valve guarantees the safety of the process. LOTUS AIR can be equipped with a gas detection sensor.

RANGE: 10-60 g/h
MAX CAPACITY: 1440 g/day

– LOTUS AIR WITH PROBE MEASURE models are also equipped with a ClO₂ probe (SVCL2/SVCL17) or an mV probe (ERH), a probe holder and a filter.

Applications

This product is designed to perform across a wide range of applications:

LOTUS MINI

LOTUS MINI is a versatile and complete solution for all your water disinfection needs. Its elegant cover preserves the cleanliness of the inner components and their integrity. Chlorine dioxide produced by LOTUS MINI can be proportional to the circulating water flow or based on a measured setpoint.

There is no storage of chlorine dioxide therefore there is no chlorine dioxide gas or concentrated solutions outside of the process application. LOTUS MINI can be equipped with a gas detection sensor.

RANGE: 8-20 g/h
MAX CAPACITY: 480 g/day

– LOTUS MINI WITH PROBE MEASURE models are also equipped with a ClO₂ probe (SVCL2/SVCL17) or an mV probe (ERH), a probe holder and a filter.

Applications

This product is designed to perform across a wide range of applications:

LOTUS MAXI

LOTUS MAXI is a series of complete and powerful chlorine dioxide generators for superior water disinfection needs, such as in large water treatment plants.
