Quantum Technology, the solution to remove foaming from biological treatment.

posted in News by

Tecnoconverting Company has developed a new technology to optimize the biological process on waste water treatment. This solution called Quantum, allows the foaming removal, by a mechanical treatment, which is formed in the biological reactor of the plant.

Recently, Tecnoconverting has finished the first tests with the Quantum Technology to study the foaming removing efficiency on biological reactors.

Quantum collects the foaming by a scraper system specially designed to avoid foaming from escaping. These scraper blades move the foam to its eliminator system, where, applying a series of mechanical processes, manages to break the filamentous structure and remove it from the biological reactor surface.

Unlike other systems on the market, the Quantum Technology does not eliminate the filamentous microorganisms in the water, it only breaks the foaming structure which they form, and send them again to the reactor to continue their beneficial contribution on water treatment.  This big difference also prevents the installation of pumps and pipelines, reducing the installations and maintenance cost.

For this study, Tecnoconverting had cooperated with Aigües de Manresa, which had placed at disposal one of its plants located in Navàs.

The study was focused on two different stages, the first, by using the Quantum Technology for its one, and the second, with the help of a small reagent dosage to see how it would affect in cases of abundant accumulation of foaming on the reactor.

To develop the study Tecnoconverting had made a documentary work of the Quantum performance by videos recording, photos and frequent visits to the waste water treatment plant.

In the first stage of the study, the filamentous foaming covered an eighth part of the reactor. These foams had fairly dense structure, easy to remove. Quantum was able to completely eliminate them in just 14 minutes.

The continuous operation of Quantum technology prevents the accumulation of foaming on the bioreactor. Only small amounts of foam are observed when the aeration system of the plant works, since there is a general movement of the waste water.

When the aeration system stops, a small residual part of foam is deposited on the Quantum deflector. This small residual part has a more liquid structure, which can difficult its elimination, but Quantum achieves it in only some minutes.

It´s difficult to predict the exact time that Quantum technology needs to completely eliminate the foaming from reactor when the machine is stopped for some time, so the foaming is accumulated, since it depends on the foam density. With Quantum technology continuous operation there can be assured the total elimination of its accumulation.

In the second step we have studied the evolution of the foam against a small dosage of sodium hypochlorite in the Quantum foaming mechanical treatment system.

Quantum is able to inject on its cylinder a small reagent quantity in order to help the breakage of foam structure in case of abundant accumulation. This dosage is concentrated only on the foam inside the Quantum cylinder, increasing the efficiency without having to add large reagent dosages.

It is very important to use small quantities of chlorinated reagents, to avoid to negatively affect the bioreactor and the effluent ecosystem pouring of the plant.

The reagent dosage on Navàs plant bioreactor was made during three consecutive days. Only 200 ml of sodium hypochlorite was dosed at 15%, during one hour per day. The results were visible, not only the foam accumulation was avoided, but also it prevented foam new generation.

The water and sludge analytical results showed how the small dosage provided in Navàs reactor did not changed the waste water treatment.

With the study it can be concluded that Quantum is a powerful system capable of removing filamentous foaming by its self, without any need of reagent addition.

With Quantum the expectations are not only based on foaming elimination. In an immediate future it´s also to enter in an energetic efficiency regimen on the reactor itself, in order to reduce the power consumption of the blowers that provide air to diffusers pipelines of the station.
