Disinfectants
General description
They are liquid formulas which are designed to clean and disinfect surfaces, spaces and tools.
Suggested Uses
- Cleaning and disinfection of waste collection bins.
- Disinfection of drinking water.
- Disinfection of private and public spaces.
- Disinfection of food areas.
- Treatment of sewage and waste water, such as urban waste water.

Application
Disinfectants are simple to use and do not differ from common cleaners. They are first sprayed onto the surface to be cleaned and then wiped with a mop and a bucket or with a cloth and a bucket, depending on the case.
Αbsorbent Materials
General description
They are advanced powdered materials with high absorption capacity (activated carbon, bentonite, zeolite, polymers). These materials are capable of absorbing multiple quantities, compared with their weight, of a great number of organic substances (Oils, Fuels, etc.) that must be bound and removed. They are insoluble in water, a feature that means they are fully functional in aqueous systems as well. These materials are safe for the user and no dust is observed during their use.
Suggested Uses
- Retention and easy removal of organic compounds, such as oils and fuels, in industrial, road and aquatic spills.
- Use in both ground and water systems.
- Cleaning storage containers.
Application
In cases of leakage, it is proposed to drop the absorbent material around the organic substance and then onto it. Removing it can be done by using a shovel and a broom. To clean storage containers, pour a layer of absorbent material into the bottom of the container and remove it manually.
Packaging
Available in plastic buckets of 13Kg. Upon order, they can also be available in larger or smaller packages.
Deodorants
General description
They are available in liquid and solid products as well as products used in vaporization devices (gel). Deodorants are consisted of mixtures of organic substances which do not overlap the unpleasant odors but neutralize them. They act effectively against a wide range of substances that cause unpleasant odors such as sulfur-based (hydrogen sulfide, mercaptans, etc.) and ammonia. Products are not dangerous for the human health and the environment.
Suggested Uses
- In liquid and solid waste treatment plants (eg papermaking, brewing).
- In biological sludge treatment.
- In garbage collection and disposal areas.
- In rubbish bins and in public markets.
- In composting plants.
- In sanitary areas (toilets).
- In pump stations and installations for treatment of liquid and solid waste.
- In sewage drains and in sewage sludge.
Application
It is recommended high pressure spray in order to efficiently handle the unpleasant odors. ENVICHEM uses automated high-pressure atomization equipment for the best use of the product through its better dispersal, reducing operating costs and human resources. There are also products that are added to polyelectrolyte solutions in order to deodorize the dehydrated activated sludge.
