Hotels need different kinds of water, drinking water, bathwater, regular tap water, for example, and different star hotels provide different water quality requirements. Depending on the location of the hotel, such as in mountains, seaside, arid areas, etc. Suitable water purification equipment should be selected according to the local water features to ensure that the water quality meets the demand of the customers.
NEWater is devoted to delivering premium high-end reverse osmosis equipment and solutions. The technological subject of NEWater is strict purification and depth treatment for a variety of water quality, combined with membrane treatment process (including microfilter or ultrafiltration, and reverse osmosis) and ultraviolet disinfection process. NEWater has provided different processing facilities for all types of hotels and has wide applications in the hospitality industry worldwide.
2. What is Reverse Osmosis
In the natural condition, the solvent flows from the dilute solution side through the semi-permeable membrane to the thick solution side when the permeabilization pressure is unequal, the natural phenomenon called permeation. Oppositely, when we put pressure on the solution. The solvent flows in the reverse and so they can obtain the elements needed for people’s production and living, which is known as the reverse osmosis process.
3. The Principles of NEWater Reverse Osmosis Technology
3.1 Preparation principle
The NEWater reverse osmosis equipment is usually composed of three parts: raw water pretreatment system, reverse osmosis purification system, and ultra-purification post-treatment system. The fundamental purpose of pretreatment is to make the raw water meet the inlet requirements of reverse osmosis membrane separation components and ensure the stable operation of the reverse osmosis purification system. The reverse osmosis membrane system can remove more than 98% of ions,organic matter, and 100% microorganisms (in theory), is the most economical and efficient purification method. The system removes the remaining impurities in reverse osmosis pure water with a variety of integration technologies to satisfy the final water quality index requirements for different purposes after ultra-purification.
3.2 Working principle
NEWater reverse osmosis refers to the application of pressure on the inlet water (concentrated solution) side to overcome the natural osmotic pressure and reverse the flow direction of the natural penetration of water molecules. The water molecule part in the inlet water (concentrated solution) becomes the purified water on the dilute solution side through the reverse osmosis film，which is the most precise membrane liquid separation technique. NEWater has tailored different reverse osmosis treatment equipment for all kinds of hotels According to the different quality of the water source, which has a good removal effect on pathogenic microorganisms, turbidity, natural organic matter, trace organic pollutants, and ammonia nitrogen in the water, which can better meet customers’ requirements for water quality.
4. Composition of NEWater Hotel Reverse Osmosis System
The NEWater reverse osmosis water treatment device is a complete set of unit equipment including between the inlet flange from the security filter and the reverse osmosis freshwater outlet flange. It includes a security filter, high-pressure pump, reverse osmosis body device, electrical, instrument, connection pipeline, cable, and other devices that can operate independently.
4.1 Security filter
To ensure the safe operation of the reverse osmosis equipment, precision filter equipment, that is a security filter (also known as a precision filter)still needs to be set up. The security filter has a variety of structural forms, water enters the security filter from the middle, the water outlet room of the lower part of the partition, impurities are kept on the filter element.
The filtration accuracy of the reverse osmosis water treatment system selection is generally 5μm. The NEWater filter element has high filtration accuracy, easy to manufacture, cheap price, and is safe to use.
4.2 High-pressure pump
As the reverse osmosis membrane operates, the water is raised to the specified pressure through a high-pressure pump to complete the desalination process. The current high-pressure pumps are centrifugal, plunger, and screw forms, and the medium and multi-stage centrifugal pumps are the most widely used. This pump is characterized by high efficiency and can reach more than 90% and save energy consumption.
4.3 Reverse osmosis body
The reverse osmosis body is a combined water treatment unit that combines and connects the reverse osmosis membrane assembly in a certain arrangement. A single reverse osmosis membrane is called membrane elements, one or a number of reverse osmosis membrane elements according to the fixed technical requirements, with a single reverse osmosis membrane shell assembly to form a membrane assembly.
Reverse osmosis film elements with industrial functions are made of reverse osmosis film and supporting materials. The rolling membrane elements are mainly applied at present. NEWater not only provides high-quality reverse osmosis membrane for the hotel industry but also enables customized production of multi-purpose membrane elements for users in various industries.
(2) Membrane housing
The pressure vessel used to load the reverse osmosis membrane elements in the reverse osmosis body device is called the membrane housing, and the housing of the “pressure vessel” membrane shell is wrapped by epoxy FRP cloth and painted with epoxy paint. NEWater can also provide customized stainless steel membrane shells according to customer needs.
5. Application of Reverse Osmosis Water Equipment in the Hotel
It is essential to have plenty of clean water that for laundry service and catering to cleaning service and personal bathroom functions when operating a hotel or restaurant business. Adding efficient reverse osmosis systems applied to the hotel ensures that guests have clean, safe, and hygienic water in bathing and drinking water, enabling a pleasant check-in experience and ultimately commercial benefits. On the other hand, hotels and restaurants require high-quality, clean water for laundry services (such as purifying linen and dishwasher) in addition to the water consumed and need to ensure that hard water does not corrode pipes or adversely affect household appliances such as dishwashers and washing machines.
It is necessary to design effective water filtration equipment systems due to most hospitality industries demand water. NEWater can meet the hotel’s various needs and will design the best system from scratch.
In order to meet the needs of clients, meet the water quality meeting the standards, reduce pollution at all levels as far as possible, in the process design, take the national tap water standard as the source water, and then equipped with a medium filter, active carbon filter, precision filter, and another pretreatment system, RO reverse osmosis host system, ion exchange mixing system, etc. Water quality meets international standards, Electronics (18MΩ*cm,15MΩ*cm,2MΩ*cm and 0.5MΩ*cm IV)
