Hotels employ a variety of systems that use water as the main working drive. Mechanical installations including domestic hot and cold water systems, closed circuit systems, cooling towers and in some cases steamboilers need the appropriate water treatment in order to operate under the optimum working conditions and ultimately minimize the maintenance costs. Mechanical installations should be protected against problems that may arise from the quality of the water used. These drawbacks include corrosion, scale deposition and most importantly microbiological growth. Most hotels are also responsible for in-house wastewater treatment to manage their domestic effluents. The running of wastewater treatment plants, pumping stations and grease traps consists of high costs if the maintenance is not done properly. The biological products in the domestic, municipal and industrial range can all be used in order to provide an enhanced, complete and environmentally friendly program that will minimize the maintenance costs but also enhance the running of the hotel. Hotels consist of vast communal premises such as restaurants, lobby, cafeterias, bars, gym but also kitchens and special refrigeration systems. The management is obligated to maintain a safe working environment for the personnel but also a healthy environment free of microbes for the quests. This can be accomplished with the use of the appropriate solution from the air purification product range. Air purification machines and filters can be fitted according to the needs of every space in order to provide air free of microbes and unwanted volatiles. Hoteliers can also promote the use of Similar Smokeless Cigarettes for both customers and personnel. In this way they will comply with the legislation but also provide a smoke free environment at the premises of the hotel. The promotion of similar smokeless can also act as an economical incentive for retailers as they will provide an added service to their customers but also create a new revenue stream for them.
