USING AVS FOR TREATMENT OF WASTEWATER FROM AND REMOVAL OF:

Hexavalent chrome and other heavy metals

Phosphates

Phenol and organic contaminants

Using AVS allows to significantly simplify the process, reduce the oxidation reaction temperature to 20-25º С, lower oxidant consumption to 2-3g per 1 g of phenol and reduce the reaction duration to hundredth of a second.
We have developed a new continuous process of decontamination waste water containing phenol and other organic contaminants using the vortex layer device.
Implementation of vortex layer device in the process of phenol removal reduced energy costs by 10 – 15 times, lowers reagent consumption by 1.5-2 times, decreases equipment footprint by 1.5 – 2 times.

cyan compounds

arsenic

The reagent used to remove waste water from arsenic was ferrichloride in carious weight ratios to the content of arsenic in the water. The exiting industrial process uses 10 times the amount of FeCl3, only bringing arsenic content to the maximum allowable limits.
In the process we used AVS-100 vortex layer device (m = 150 g, τ = 3-5 seconds), and with the consumption of the reagent in the same amount as in the exiting technology, no arsenic was detected in purified water. Using a 5 time excess of the reagent yields the same results, while 3 times excess significantly lowers the concentration from initial 2115 mg/dm3 to residual 116 mg/dm3.
Research shows that the use of vortex layer device while removing arsenic from waste water allows to completely precipitate the arsenic after 1-5 seconds of processing in the vortex layer and reduce reagent consumption by 3-5 times compared to the regular technology, simplify the process and make it continuous.

fluoride and nitrogen compounds

Research performed in the area of decontamination and fluor removal from waste water using AVS shows that these devices are more efficient compared to the existing equipment.
Fluor removal and transformation of phosphates into water-insoluble compounds occurs in one stage. The content of fluor in purified waste water in optimal conditions (pH = 10-11) up to 1.5 mg/dm3, no phosphates. Duration of processing in the vortex layer: 1-3 seconds. A reasonable choice of reagent is lime with 5-10% excess of CaO from the theoretically calculated amount. Using AVS in the process of fluor removal reduces reagent consumption, electric power consumption, equipment footprint and improves the quality of purification.

Manure Odor & helminths

hog and cattle waste

The laboratory tested six samples, of which two samples were taken from mice, contaminated by extract of hog and cattle feces without processing of the material in the vortex layer system, our control group, two samples with 2 minute processing time of initial material and two samples with 5 minute processing of initial material.
• Helminthes larvae was detected in droppings of control group mice
• Samples with 2 minute processing duration were also contaminated by larvae
• No helminthes larvae was detected in samples, obtained from initial materials processed for 5 minutes.
