Reactivation of granular activated carbon

It is possible to reactivate spent granular carbons by various methods, among which the most common is thermal (in a rotary kiln at 800 ° C and in an atmosphere saturated with water vapor). The coal obtained usually recovers all its original capacity. With reactivation, the need to dispose of spent carbon (as industrial waste) is avoided and up to 50% can be saved in the replacement of activated carbon - reactivation.


All activated carbon that is applied in water purification, sooner or later becomes a source of bacterial proliferation (due to the organic matter that it retains). Then it becomes necessary to sanitize the coal, a task that is not easy since the coal decomposes the oxidizable agents that are used for this purpose (chlorine, ozone, hydrogen peroxide, etc.). Our company offers the service, the advice and the product suitable for sanitization.

Technical advice on activated carbon and water treatment.

In case of determining that activated carbon is the most competitive solution to a purification problem, we select the most suitable carbon, design and select the equipment by means of adsorption isotherms, column processes at the laboratory level and in pilot plants. Solution of operational problems and optimization of the operation.

Change of granular media beds (activated carbon, sand, anthracite, etc.)

We offer the correct installation and commissioning of all types of beds, based on the technical standards of recognized organizations, such as ANSI and AWWA.

Installation and maintenance of equipment for water treatment.

We install and maintain water treatment equipment such as: filters, industrial filters, activated carbon purifiers, reverse osmosis, water softeners (water softeners), ozone generators and ultraviolet light equipment.

Recycling of granular activated carbon canisters

The canisters offered by Carbotecnia are drums that, in addition to containing activated carbon, are connected as purification equipment. When the coal has been saturated, in addition to recycling the coal, the canister is recycled to avoid maintenance work in your company.

Reverse osmosis systems maintenance

Reverse osmosis membranes require chemical treatment to remove deposits of carbonates, silica and organic matter, as well as the control of microorganisms that develop within them.
