From its head offices in Barcelona, the company manages and coordinates its seven production plants and its distribution centers throughout the Iberian Peninsula, in addition to exports to the European Union market and the rest of the world.

Water Treatment

Thanks to being highly versatile and environmental friendly, hydrogen peroxide can be used in either biodegradable or oxidation refractory sewage treatment, as well as in many other environmental applications.

OHP: Technology for Sewage Water Treatment by Humid Oxidation with Hydrogen Peroxide.

The OHP (Humid Oxidation with Peroxide) system is extremely flexible in being able to cope with all effluent conditions. Apart from its simple conceptual design, reliability and high efficiency, it is fully automated which means there is little or no need for operational management. Being so versatile means than the end user can program the level of treatment he requires at any given time.

Another major advantage over other systems is the speed with which the system is actually brought on line; one hour is all that is required as opposed with the 2 to 3 weeks required by biological systems. For this reason OHP(Humid Oxidation with Peroxide) is flexible and adaptable to any condition of plant as it can be used either as a continuous process or indeed as an intermittent batch process.

OHP Safety

The OHP (Humid Oxidation with Peroxide) system has been designed in accordance with the most stringent engineering and safety codes at present applicable in the chemical industry.

OHP (Humid Oxidation with Peroxide) operates at considerably lower temperatures and pressures compared to other advanced oxidation processes, which makes for an intrinsically safer and cheaper to construct systems.

The OHP Process

OHP (Humid Oxidation with Peroxide) gives far better results in the treatment of difficult liquid effluents than those achieved using conventional treatments such as physical-chemical, biological and other classic oxidation processes which use chlorine, ozone, chlorine-dioxide and oxygen and which are not always efficient in dealing with particularly nasty by-products.

The OHP (Humid Oxidation with Peroxide) process oxidizes organic matter by making use of the free radicals (Hydroxyl and perhydroxyl radicals) which are in turn produced when hydrogen peroxide is subjected to a controlled break down and catalytic process.

The key to the OHP (Humid Oxidation with Peroxide) process is in fact the development and optimization of the control of this chemical reaction, thus enabling maximum efficiency of the oxidation process, through the free radicals, finally giving the required performance at a reasonable cost.
