Ercros commitment to its water treatment range
15 June 2012. - In a bid by Ercros to help strengthen the water treatment industry, the company is focusing its efforts in R & D toward improving the properties and uses of products in this market. Thanks to this effort, the company has developed new applications for sodium chlorite as a biocide, and has patented some new tablets used in the treatment of water in swimming pools without boric acid.
Ercros is promoting the use of sodium chlorite as a biocide in the desalination process of seawater. This is a field seeing new action and expansion, in which the use of sodium chlorite is highly recommended in the primary disinfection stages, since these facilities have a high risk of formation of trihalomethanes (THM) due to high content of bromides in seawater. Similarly, the use of sodium chlorite is advantageous for inhibiting deposits of microorganisms in the osmosis membranes of water purification plants.
THMs are volatile chemical compounds that are generated during the water purification process, from the reaction of as yet untreated organic matter with the biocides used to disinfect it. In recent years, European legislation has reduced the allowable level of THMs in water for human consumption.
The department of R&D at Ercros is also working on the development of sodium chlorite as pest control for the zebra mussel, which is seriously impeding water intake in river basins, particularly in the area around the mouth of the Ebro. In collaboration with the University of Zaragoza, the company has tested the effectiveness of sodium chlorite both in eliminating the larvae, and the control of adult specimens— with excellent results.
Ercros has also patented some new tablets for treating swimming pool water without boric acid, using a formula of its own fabrication. The new tablets improve user safety and anticipate any possible regulatory changes in European regulations. The improvement ushered in by Ercros' tablets was awarded with a special mention for sustainability at the International Swimming Pool Fair '11, held in Barcelona.

New range of tablets free of boric acid
Ercros announces the market launch of its new range of swimming pool water treatment tablets, which are free of boric acid, under its own three brand names, Delsa, Azuli and Pisipur. The production formula has been patented by the company.
The new Ercros tablets improve user safety and pre-empt any possible changes to European regulations. Until now, boric acid has been used to facilitate chlorine compression in tablet presentation. However, the European Chemicals Agency has recently included this compound in the candidate list of substances of very high concern for authorisation, in line with the Reach regulation. As such, the R&D department at Ercros has focused on obtaining a replacement for this product in the tablet manufacturing process. Ercros is an European leading company in sales of chloroisocyanurates, which it manufactures at its Sabiñánigo factory (Huesca). The company's facilities and products comply with European and Spanish regulations concerning safety, transport, storage, packaging and labelling. Its products have been authorised by the Spanish health authorities, European Union countries and Canada. In the USA they are registered by the Environmental Protection Agency (EPA). The company is a member of the US Isocyanurate Industry Committee. Furthermore, since 1994 Ercros has been committed to the Responsible Care programme, an initiative of the Business Federation of the Spanish Chemical Industry (Feique). The goal of the programme is to encourage companies to make continuous improvements in their activity in terms of safety, health protection, the environment, product distribution and stewardship, and communication with the interested parties.
The University of Zaragoza awards the project of microencapsulation from Ercros factory in Sabiñánigo
Barcelona, june 12, 2015. - Professor Joaquin Coronas from the Institute of Nanoscience of Aragon, and the R&D department at Ercros factory in Sabiñánigo have been recognized in the awards "Triple Hélice" granted by the University of Zaragoza for its project of microencapsulation of substances in the tablets for pool water treatment.
The prizes "Triple Hélice" award projects in which the collaboration between university and business results in the development of innovative products. Professor Coronas and Ercros have been finalists in its category developing microcapsules, which incorporated into pool water treatments tablets, give off insect repellents and fragrances.
Tablets for the treatment of pool water are made of trichloroisocyanuric acid (TCCA), and they dissolve slowly in the water while releasing chlorine. The challenge faced by professor Coronas and Ercros team was getting these tablets also gradually free mosquito repellent or fragrances, avoiding to be degraded by the action of ATCC. The solution was microencapsulate, that is to say introducing in micropores the substances and thus, "protect" them from the action of the ATCC. The result of this collaboration between business and university is an innovative product and a new patent.
Ercros is the largest European manufacturer of ATCC that is produced at its plant in Sabiñánigo which has a production capacity of 21,000 tons annually.
Ercros keeps an important activity in the field of innovation and technology. All their business have their own department, from which develop new products or processes and investigate new applications for existing products in its portfolio. At present, the company has 14 patents.

As it looks to tap into the potential of the water treatment sector, Ercros is focusing its R&D work on improving the properties and uses of the products used in this line of business. As a result of these efforts, the company is presenting new applications at Expoquimia, namely sodium chlorite used as a biocide and boric acid-free tablets for the treatment of swimming pool water.
Ercros is promoting the use of sodium chlorite as a biocide in the seawater desalination processes, a relatively new and growing area. The use of sodium chlorite is highly recommended in the initial disinfection stages in facilities of this kind, which are at significant risk of trihalomethane (THM) formation due to the high bromide content of seawater. Furthermore, the use of sodium chlorite is advantageous in terms of inhibiting deposits of micro-organisms in the osmosis membranes of water purification plants. THMs are volatile chemical compounds that are generated during the water purification process due to the reaction of the organic material yet to be treated with certain biocides used for its disinfection. In recent years, European legislation has reduced the permitted level of THMs in water for human consumption. Ecros¿ R&T department is also working on the development of sodium chlorite for the control of the zebra mussel pest, which is seriously complicating the collection of water from river basins, especially in the area at the mouth of the River Ebro. In collaboration with the University of Zaragoza, the company has tested the effectiveness of sodium chlorite, both in the elimination of larvae and the control of adult specimens, with excellent results. Ercros has just also launched on the market its new range of boric acid-free tablets for the treatment of swimming pool water, with a production formula that has been patented by the company.

Ercros is the sales leader in the European market of tablets for the treatment of swimming pool water, which it also manufactures in its Sabiñánigo plant.
