Hospitality, restaurants and catering (HORECA) share a structural challenge that directly affects their operational, regulatory and environmental viability: wastewater management. Salher\u2019s approach to treating these waters combines engineering, manufacturing and technical support to help businesses address this challenge effectively.<\/p>\n

Professional kitchens, washing areas, cold rooms and service zones generate highly variable and complex effluents with high loads of fats and oils, coarse and fine solids from organic waste, food residues and packaging, high organic load (elevated COD and BOD\u2085), as well as detergents and disinfectants that may interfere with biological treatment processes.<\/p>\n

The HORECA sector requires compact, easy-to-operate solutions capable of adapting to peak activity and limited spaces. In this context, Salher supports hotels, restaurants and catering companies in what has become a structural challenge: managing wastewater according to sustainability and efficiency criteria.<\/p>\n

Without adequate treatment, these discharges can cause blockages in sewer networks, unpleasant odours, increased maintenance costs, administrative penalties and, in extreme cases, temporary facility closures. For many HORECA businesses, wastewater management is not only about regulatory compliance, but also about operational efficiency, business continuity and reputation.<\/p>\n

Experience shows that there is no single solution, but rather a combination of technologies tailored to each point of wastewater generation. With this integrated approach, Salher\u2019s solutions cover the entire cycle, from pretreatment to treatment and reuse.<\/p>\n

Kitchens and food preparation areas<\/h3>\n

Professional kitchens are the main source of fats and organic residues. For this reason, the installation of grease separators is essential to protect internal drainage systems and comply with discharge limits.<\/p>\n

Salher grease separators, manufactured in GRP or stainless steel, are designed to:<\/p>\n
