Salher: quality manufacturer of water treatments, with 40 years of experience

Engineers and Manufacturers. Salher has become a specialist in the design of wastewater treatment, reuse and drinking water systems, with special care in the performance, operability and durability of the systems. This is how the Spanish company obtained its first quality certificates issued by an approved body by ENAC: the Salher water treatment plants were subjected to structural behavior and performance tests according to the UNE-EN 12566-3 standard.

Progressively, Salher has been adding certifications, such as the one regarding the design and manufacture of hydrocarbon separators. These equips have undergone structural, chemical resistance and impact resistance tests, as well as performance tests based on UNE-EN 858-1. Also Salher pumping stations are designed according to the EN 12050-1 standard.

Salher is an entity clearly committed to the management of its Quality System, established since 2003. In 2018, with the implementation of the new ISO 9001: 2015, Salher expanded the scope of its Quality management system to tertiary treatments of water and drinking water systems, with assembly tests and internal functioning tests.

Salher equips are manufactured according to regulations and following customer specifications

Control of internal production

To control the manufacture of the Salher equips, the Production Department, under internal supervision of the Quality Department, carries out the following quality controls:

Dimensional control: The important dimensional parameters are measured: diameter, length and thickness.

Tightness control: Water is introduced into the tanks in order to check that there are no leaks or pores, as well as any other anomaly on their entire surface.

Thickness test: Salher certifies that, according to its ferrules, flat bottoms and Korboggen caps manufacturing system, for the thicknesses calculation and according to the theory of thin sheets of resistance of materials for building elements, minimum thicknesses have been defined, measured with the help of a tester (micrometer, feeler gauge or any other appropriate instrument).

Barcol hardness test: Salher certifies that the characteristics of the laminate comply with a minimum value of 80% of that specified by the resin supplier, after a 24-hour post-curing process.
