Reagents-Free Fluids Decontamination

//Reagents-Free Fluids Decontamination

DEWA impact is the unique reagent-free solution for liquids decontamination.

Cavitaion impact of RIA (Rotary-imPulse-Apparatus) on liquids destroys colloids&particles which might contain bacteries. Bactercidal effect of RIA is directly proportional to its intensity, multiplicity and time.

Decontamination Mechanisms

Cavitation destroys colloids and particles which contain bacterias. Thus, pathogens are deprived of the protection to other chemical and physical impacts.

The bactericidal action of cavitation is directly proportional to its intensity: the higher the number of cycles of DEWA-impact, the stronger the effect.

The impact of cavitation on aqueous solutions follows the splitting of water molecules in cavitation bubbles. Effect of cavitation on water leads to a change in its physico-chemical properties: an increase of pH, electrical conductivity of water, increasing the number of free ions andactive radicals, structuring and activation molecules.

Impact of high-intensive cavitation shock waves on bacteria like Salmonella or E-coli can reduce their numbers by thousands of times. The impact of cumulative jets of liquid at the collapse of cavitation microbubbles causes the death of the bacteria.

Results

Experiments show that 5-time (5 cycles) DEWA treatment significaly (near 100%) reduces the presense of viable spores suspension of Fusarium solani and the length of actinomycete mycelium.

DEWA treatment of sewage water reduces the number of:

  • coliform bacteria on 100k times
  • thermotolerant bacteria – 60k times
  • coliphages (bacterial viruses) – more than 80k times.

3 Coliphages (bacterial viruses), PFU per 100ml  86 not obtained  ≤100

DEWA is a unique solution for the complexes of water decontamination. Its bactercidal effect could be used both as a part of common cavitation+UV+O3 water treatment and independently.

DEWA Decontamination is an effective technology for cleaning of sewage water, pool water, and especially for the destroying the sludge (mud) of treatment facilities.

 

DEWA-impact for the purpose of decontamination is effective for many liquids, slurries, bio-humus, beer bard.
