Resorts

For hotel resorts, wastewater treatment plants are crucial to  keep the quality of water in the surrounding area pristine and to meet environmental regulations.

The type of wastewater treatment process selected is based on your environmental discharge license and any reuse criteria you may desire or require. Hydroflux Pacific’s solutions range from the simplest and most robust process found in the RoadTrain  activated sludge plant to the high-performance Membrane Bioreactor . For large resort complexes, Hydroflux Pacific can also offer the unique Organica process which is an architecturally designed treatment plant that combines natural native plant life with activated sludge treatment systems.

The Roadtrain activated sludge plant is one of the most robust and simple to operate wastewater treatment plants favoured by resorts of all sizes.

Potable water, or drinking water, is an essential part of everyday life and a reliable supply of potable water is a critical asset of any resort. Whether your source of water is from bores, surface water dams, mains supply or desalinating sea water, Hydroflux Pacific can provide high quality reliable potable water treatment systems for small boutique establishments or a large resort complexes.

Our potable water treatment solutions are customised on your raw water source and quality and guarantee a consistent potable water supply to your resort.

The solutions range from the simplest media filtration units to treat high quality surface water through to the most advanced reverse osmosis treatment solutions that generate potable water from sea water.

Ground water bores | HyPure® | Surface water | Sea Water RO | Municipal Water Supply

Ground water bores 

Bore water is groundwater that is extracted from a borehole, and the quality of bore water can vary depending on the location and the geological characteristics of the surrounding soil and rock formations. In some areas, the groundwater may have a high level of salinity due to the presence of dissolved minerals and salts, making it brackish.

Brackish water is treated through a variety of methods depending on the cleanliness of the water and the level of salinity. The most common methods of brackish water treatment Hydroflux has adopted for resorts can involve one or a combination of the processes shown below.

In situations where the water exhibits high turbidity, the initial stage of treatment will usually involve chemical coagulation followed by clarification. This process aims to remove suspended solids and particles from the water, enhancing its clarity and reducing turbidity.

For non-brackish water with low levels of dissolved salts, the secondary and final treatment approach involves media filtration followed by disinfection. Media filtration effectively removes impurities and particulate matter from the water, while disinfection destroys harmful microorganisms, ensuring the production of potable water.

In the case of brackish water, a popular method of treatment is the utilisation of reverse osmosis (RO). This involves passing the brackish water through a semi-permeable membrane to effectively remove dissolved solids and salts. Reverse osmosis is highly efficient, capable of removing up to 99% of salts and minerals present in brackish water. Hydroflux can also incorporate Ion Exchange technology for similar purposes, utilising a resin bed that facilitates the exchange of ions.

Surface Water

Surface water collected in dams at resorts can be treated to make it safe for drinking and other uses. The treatment method used will depend on the quality of the surface water, but the most common methods of surface water treatment adopted by Hydroflux Pacific at resorts include:

• Coagulation and flocculation: This is the initial step in the treatment process where chemicals are added to the water to remove suspended particles and turbidity. Coagulants like alum and ferric chloride neutralise the charges on suspended particles and form larger aggregates called flocs that can be easily removed.
• Sedimentation: The water is then allowed to settle in a clarifier, allowing the flocs to settle at the bottom of the tank. This process removes large particles and flocs from the water.
• Filtration: The water is then passed through a series of filters, including sand, gravel, and activated carbon, which remove smaller particles, organic matter, and bacteria.
• Disinfection: After filtration, the water is disinfected using chemicals like chlorine, ozone, or UV light to kill any remaining bacteria, viruses, and other pathogens.

Hydroflux Pacific has vast experience in the treatment of surface water and the applications described above. Systems can be containerised for easy deployment or provided on skids for partial assembly on site.

What is the water quality required for discharging wastewater from my resort?

The specific water quality requirements for discharging wastewater from a resort in the Pacific can vary depending on several factors, including local regulations and environmental considerations. Hydroflux can assist in establishing the requirements and approvals.

What information is needed to provide a wastewater treatment plant design?

In order to prepare a design and costing for a wastewater treatment plant, we would require the following information to start to selection.

• The number of people or beds taking into account expansion plans
• The expected lifespan of the site (not the equipment but the entire site)
• The discharge license criteria which is typically solids, organic load (ie BOD or COD) and nutrients (Nitrogen and phosphorous) – Hydroflux Pacific can assist with this along with any reuse intent

What type of water treatment system do I need at my resort?

A reliable supply of potable water, or drinking water, is a critical asset of any resort. The type of system required is entirely dependent on the source of raw water be it from bores, surface water dams, mains supply or desalinating sea water, Hydroflux  Pacific can provide high quality reliable potable water treatment systems to suit any water supply.
