Applying ENSO Deodorizing Granules Technology to Enhance Guest Experience and Tourism Service Standards

I. BACKGROUND

In the premium tourism and hospitality industry, fragrance experience and indoor air quality directly influence guests' overall impressions. Even a slight unpleasant odor in public areas, restaurants, waste collection stations, wastewater treatment systems, or odors discharged through ventilation systems into surrounding environments can seriously affect a resort's or hotel's brand image and service ratings.

Common odor issues include:

·        Odors from waste collection stations spreading throughout the premises.

·        Odors from wastewater treatment systems affecting accommodation areas.

·        Food odors lingering in buffet and dining areas, clinging to guests' clothing.

·        Cigarette smoke odors in smoking rooms and enclosed spaces.

·        Musty and organic odors in service areas.

·        Restroom odors discharged through ventilation systems into surrounding environments.

·        Kitchen smoke odors when cooking fumes are not properly collected and treated.

Particularly in coastal tourism cities such as Da Nang, the hot and humid climate accelerates odor generation, negatively impacting:

·        Guest vacation experience

·        Service hygiene standards

·        OTA ratings (Booking.com, Agoda, TripAdvisor, etc.)

·        International brand image

·        Working conditions for operational staff

Therefore, adopting professional, safe, and environmentally friendly odor control solutions has become an essential trend in the premium hospitality industry.

II. OBJECTIVES

To effectively control and eliminate odor sources in resorts, hotels, and restaurants in order to improve customer service quality by:

·        Enhancing guest experience and service standards

·        Reducing environmental impacts on tourism facilities

·        Increasing guest satisfaction and positive reviews

·        Supporting the development of green, clean, and sustainable tourism models

III. ENSO ODOR CONTROL SOLUTIONS FOR EACH AREA

1. Odor Control Solution for Waste Collection Stations

1.1 Current Situation

Resorts, hotels, and restaurants generate large volumes of:

·        Organic waste

·        Food waste

·        Seafood waste

·        Household waste

·        Food packaging

Under high-temperature conditions, waste collection areas commonly generate:

·        Hydrogen sulfide (H₂S)

·        Ammonia (NH₃)

·        Organic acidic odors

·        Decomposing food odors

These odors can spread to:

·        Internal walkways

·        Villa areas

·        Swimming pools

·        Outdoor restaurants

·        Downwind areas of the property

1.2 ENSO Solution

·        Store waste in enclosed waste storage facilities.

·        Install the ENSO Odor Filtration System to treat and prevent unpleasant odors from spreading to surrounding areas.

1.3 Benefits

·        Rapid reduction of organic odors

·        Reduced flies and insects

·        Fewer guest complaints

·        Improved working environment for sanitation staff

2. Odor Control Solution for Wastewater Treatment Systems

2.1 Current Situation

Most resorts and hotels operate their own wastewater treatment systems. However, odor emissions commonly occur from:

·        Equalization tanks

·        Grease traps

·        Aeration tanks

·        Sludge dewatering areas

These systems generate gases such as:

·        Hydrogen sulfide (H₂S)

·        Mercaptans

·        Ammonia (NH₃)

·        Volatile Organic Compounds (VOCs)

These odors can easily spread with sea breezes and affect resort areas. In hotels, odors originating from basement facilities may also travel through corridors and ventilation systems, impacting guests.

2.2 ENSO Solution

·        Localized ENSO odor adsorption system

·        IoT-based automatic control

·        Odor sensors

·        Time-based and odor-load-based operation

2.3 Benefits

·        Odor control at the source

·        Reduced odor emissions into the environment

·        Minimized impact on premium resort areas

·        Enhanced green environmental standards

·        Support for ESG goals and sustainable tourism

3. Odor Control Solution for Buffet Dining Areas

3.1 Current Situation

Buffet areas, dining rooms, and banquet halls commonly contain:

·        Grease odors

·        Seafood odors

·        Food odors

·        Mixed cooking odors

Especially in enclosed spaces or during high-capacity service periods, odors tend to linger, resulting in:

·        Guest discomfort

·        Reduced appetite and dining experience

·        Food odors clinging to guests' clothing after meals

3.2 ENSO Solution

·        Air recirculation odor treatment system

·        ENSO deodorization system integrated into ventilation systems

3.3 Benefits

·        More pleasant dining environment

4. Cigarette Smoke Odor Control Solution for Smoking Rooms

4.1 Current Situation

Cigarette smoke contains:

·        Nicotine

·        Tar

·        VOCs

·        Persistent smoke odors

In smoking rooms, these odors remain for long periods and easily spread into corridors, affecting non-smoking guests, women, and children. This is one of the common causes of negative reviews in luxury hotels.
