FATTY

ACIDS

•Fatty acids : Sourish odors, sweat odors, olive oil processing industries odors and etc can be named in this class. Generally the source of this kind of an odor is rancidity, various fermentations, sweat and etc. Because the odors in this class cause relatively smaller troubles compared to the other odor problems and are more easily competed, they do not cause serious problems.

SULFUR

COMPOUNDS

•Sulfur compounds : These odors are generally formed of organic sulfite and mercaptan. They are generally caused by sources like anaerobic reactions, rotten zucchini and similar plants, decay of dead bodies. 

NITROGE

N COMPOUNDS

•Nitrogen compounds : These odors are generally caused by amines. Practically they are generated from rotten fish, dead bodies, urine and etc or other sources. 

CLASSIFICATION OF FOUL ODOURSEvery part of an odor molecule does not stimulate the odor receptors in the nose. Usually a limited part of the molecule stimulates the receptors and send an odor signal to the brain. Referring to the active material in it we can classify the foul odors to three types. 

CLASSIFICATION OF FOUL ODOURS

AGENT MOLECULE SMELL

SULFUR Methyl Sulphide

Rotten Garbage

COMPOUNDSMethyl

Disulphide Onion

• Besides the mentioned classification of odors, in some rare cases the nitrogen in the reactive part of some of the odor molecules is replaced by phosphore and the sulfur is replaced by selenium. In such cases the odor is even stronger and irresistible .

• If we look at the case of odors from the theoretical side, the table can describe which chemicals cause which odour.In practice a foul odor is not formed by only one of these agents. But usually it is a case of a composition of many of these agents. For example in many cases an odor includes sulfur and nitrogen molecules at the same time

DE-STINK

• ECO-FRIENDLY

• LONG LASTING

• FAST AND EFFECTIVE

• VERY SAFE

• HAS MULPITLE USES, IN BOTH PERSONAL CARE & INDUSTRIAL APPLICATIONS

PRODUCT PROFILE

• De-Stink is a very eco-friendly & green odor absorber. De-Stink is derived by combining zinc with Ricinoliec acid – renewable & abundantly available vegetable oils, etc. 

• De-Stink chemically combines with odor causing molecules like nitrogen or sulfur containing substances which are generated during Industrial processes or during food & organic matter decaying process. Such substances include amines, short chain carboxylic acids, mercaptans,thioethers,hydrogen sulfide,isovaleric acid,etc .In general terms, De-Stink is very useful in absorbing mal-odors like Garbage dumps,pet smells,sweat ,cigarette smoke,foods like garlic,etc. De-Stink chemically binds itself to these odor causing molecules & thus remove these odors very effectively unlike other synthetic products used for odor masking or perfumes,etc.

• De-Stink does not have bactericide or bacteriostatic activity & thus it does not interfere with bacteria culture used in Industrial manure manufacturing units. Thus it is a very safe products & used worldwide even in cosmetics products like deodorants, lip balms, foot care creams,etc .It is also used in other formulations like cupboard deodorizers ,shoe deodorizers, fabric & mattress deodorizers,etc.

• De-Stink is particularly suitable in arresting foul odors emanating from garbage collection centres,during transporting of garbage from cities to dumping grounds,etc by installing dosing & spraying systems.  

• METCO offers ready to use De-Stink formulations & technical support for installing spraying systems to ensure effective as per individual customers requirements. Please contact Evolvchem for further assistance & samples as well as at-site-demonstrations

ABOUT DE-STINK

DE-STINK TECHNOLOGY De-Stink remove’s malodours by permanent chemical bonding.

De-Stink is an active malodour absorber

Neutralization: The active mater in De-Stink initially targets the odour molecule. The special molecular structure of De-Stink locks the foul odour molecule and blocks its structure capable of stimulating the receptors in the nose. 

DE-STINK TECHNOLOGY

Settling : When De-Stink is applied by misting systems, the mist created captures the foul odour molecules and slowly settles down. With this effect very similar to the effect of rain in the atmosphere, air is washed by a mixture of water and De-Stink.

DE-STINK APPLICATION METHOD’S

There are different ways that De-Stink products are applied. The method of application usually depends on the source of the odour. 

It is possible to apply De-Stink by manual or automatic methods. When using simple hand pumps or sprayers a solution of 1-5 % is applied whereas a solution of 0.01 – 0.1 % can be applied in automatic misting methods.

For automatic applications we suggest the high pressure misting systems that suit best with De-Stink products by means of forming a perfect mist and providing an excellent homogenous dispersion of the product.

In spite of this De-Stink chemicals can well be used compatibly with all kinds of lower pressure sprayers and perfume dosing systems on the market.

ACTIVITY ON GARBAGE

At a field test on H2S gas, which is the main reason of foul odour problems at decomposing dumps garbage was placed in a closed container. After waiting for some time for the anaerobic fermentation to start 0,1 % solution of De-Stink was periodically sprayed in the tank.

As it is seen in graph application of De-Stink degrades the H2S concentration to 200 ppm from its initial level of 700 ppm. After stopping the application the increasing concentration of H2S to 800 ppm level proves the strong activity of the product on H2S degradation

ACTIVITY ON AMINES IN GASEOUS FORM

In this test where the effect of De-Stink was tested on amines a certain amount of cyclohexylamine was dosed in a closed drum. After waiting for a while for cyclohexylamine to get homogenous in the medium, a dose of De-Stink was periodically sprayed in the drum. Graph below shows the measured cyclohexylamine concentrations in the application and control drums

DE-STINK APPLICATIONS AREAS

Deodorization of waste water treatment plants, sludge thickening basins, sludge dewatering units, transportation storage and dehydration processes of dewatered sludge and similar units and processes.

Deodorization of Urban solid wastes transporting, processing plants, solid waste storage areas, composting plants, urban solid waste transportation trucks, wash water of these trucks, leak water of urban solid wastes.

Degradation of odours generating from urban sewer systems, lift stations, open air sewers and etc.Deodorization of foul odours in domestic applications, like hotel rooms, smoking areas, garbage rooms, kitchen and shower drains and etc.Deodorization of exhaust gases from kitchens and other food processing plants.

Deodorization in hospitals, slaughter house, morgues, etc.
