Water reuse

Created to recycle water from a wastewater treatment plant

What is water reuse (REUSE)?

The answer is already there! Water reuse (REUSE) refers to the process of recycling and reusing water which has already been used. It is similar to setting up a circular water economy system. Doesn’t that make sense?

LREUSE is a common way to deal with global water challenges, such as scarcity due to increasing droughts. With this technology, managing water requirements becomes much easier, as existing facilities, such as clarifiers, can be used to provide quality water. This represents a major step to preserve water, which has been growing more and more difficult to obtain and is a precious resource.

Among other benefits, the REUSE allows to:

  • maintain and reuse water resources
  • greatly reduce freshwater needs
  • reduce processing and distribution costs.

REUSE implementation may take several forms, including: .

  • wastewater collection and treatment for agricultural irrigation,
  • groundwater refill,
  • Filling up hydro-cleaning trucks and road cleaning machines
  • rainwater use for domestic purposes.

Such a practice can also reduce the environmental impacts associated with wastewater discharges. In fact, any nitrate coming out of the wastewater treatment plant that is reused for irrigation, for example, will not be released back into the river and will not be purchased by the farmer.

Why reuse wastewater?

Given recent events, no one has missed it, right? Are you interested in climate change? We have more and more droughts, less and less water.

However, processed water remains discharged at the end of the wastewater treatment plant without rehabilitation. Why not make treated wastewater a valuable resource? And this is where wastewater reuse can help.

Managing water sustainably is one of the main concerns for the world, and the current scarcity of water resources has become a serious reality. So it’s time to change the way we do things and reuse wastewater to supply domestic water needs. Wastewater reuse can help to:

  • reduce demands on freshwater supplies by offering an alternative source of water.
  • Reduce river, lake and ocean contamination by lowering the amount of wastewater discharged into the environment.

Anything that is reused is something you don't have to consume. It's easy, compact, low-tech

What are the benefits of water reuse (REUSE)?

Anything that is reused is something you don’t have to consume. Furthermore, reusing water allows to save system efficiency, i.e. 1.2 to 1.5 times the reused volume.

And you know what? All of this volume will be saved and will remain in the river for fish and other aquatic organisms. But wastewater reuse does not only provide benefits for the environment and sustainable water management. It also helps to:

  • meet food security challenges, by allowing agricultural irrigation;
  • Satisfy the economic constraints, by allowing substantial savings of drinking water;
  • reduce freshwater needs, while providing a stable source for non-potable uses. Among these are green space watering, public road cleaning or groundwater refill.

Presentation of the product "Water REUSE Skid" and its advantages

Water REUSE Skid is the perfect water reuse system for companies or communities. It is easy, compact, low-tech and the skid fits in small spaces.

It works by filtrating water through an advanced filtration system that removes impurities and contaminants. This sterilized water is subsequently reused in the production process or for irrigation.

By reusing water, many companies can save a lot of money. These include water supply costs, carbon footprint reduction and water resource preservation.

How to set up a water reuse project (REUSE)?

Water reuse projects are growing in popularity as a result of the economic and environmental benefits they offer. To establish this kind of project, you need to determine the final objective. Depending on these factors, our teams will determine the most appropriate equipment.

  1. First step, you have to know where you want to go: which application you want to use? Which standard should be respected? Which resource is available?
  2. The second step is to assess available water sources: treated wastewater, rainwater or borehole water, surface water… You must determine the desired flow rate here
  3. Once the water sources identified, it is important to determine the water quality and treatment requirements for the intended application: transmittance analysis, TSS, COD, Iron
  4. The fourth step is to choose the right equipment for the water quality. A variety of equipment exists. We have prepared a free online design form available below.
  5. A distribution system must then be developed to suit the use and the treatment equipment. You will get a new industrial water network that can supply many equipments.
  6. Finally, regular maintenance of the water reuse system is important to ensure savings and resource conservation. In most cases, annual cleaning of lamps is enough.

What are the different types of water reuse?

Wherever water is needed, water reuse (REUSE) is a valuable solution to meet water needs. There are different types of water reuse depending on the application and quality requirements. Among these frequent reuse applications, we have:

    • Agricultural irrigation
    • Watering of green spaces, parks, stadiums or golf courses
    • Restrooms and toilets
    • Fire fighting systems
    • Industrial processes
    • Car washes
    • Fountains, waterfalls and decorative ponds
    • Rainwater recycling systems
    • Cooling systems
    • Groundwater or water plan refill

All of these applications require different water quality and treatment requirements, as well as advantages and disadvantages.

However, agricultural reuse is one of the most relevant because of the presence of nitrogen and phosphorus in wastewater output

What are the standards and regulations regarding water reuse?

Reuse water is a growing practice around the world. However, standards and regulations will change from country to country, and even from region to region. Actually, it depends on the country. Some countries, especially in Africa, are taking a very pragmatic approach to REUSE and have implemented simple and inexpensive solutions to reuse water. Some countries, such as France, are very strict in terms of regulations and love paper to the point of putting obstacles in their way. In Australia, reuse is regulated under strict standards to ensure the quality of the reused water, which severely limits the type of resource that can be reused. Once again, it all depends on the intended end use. If you want to make drinking water from wastewater, then you must meet the criteria of the that ensures high water quality for the end users.

What are the water treatment techniques for reuse?

Different water treatment techniques are available for reuse, adapted to different types of applications. For wastewater recycling, it is best to use on-demand treatment. It allows to produce water of quality adapted to each use without worrying about storage.

UV filtration and disinfection are ideal for reusing water after treatment. Storage of treated water requires chlorination to prevent bacterial growth. However, watering crops with chlorinated water is not an option, is it? Other water treatment techniques such as microfiltration, reverse osmosis and nanofiltration can also be used to remove impurities and contaminants. They are efficient but expensive to purchase and operate.

Choosing the right water treatment technology depends on the specific needs of each application. UV filtration and disinfection is the best quality/price solution. 1h2o3’s compact equipment will allow you to treat your water upstream of the water REUSE skid efficiently, for example with a drum filter or a lamella clarifier.

Is the reused water (REUSE) potable?

Reused water is often untreated to meet drinking water standards. Whether reused water is safe to drink remains a concern for many users. It depends again on the original purpose, the quality of the water and the treatment it has undergone. It is possible to treat the reused water to make it potable using advanced water treatment technologies such as ozonation and nanofiltration. These technologies are expensive and all equipment must be certified, adding to the cost.

However, the large cost of this treatment raises questions about its relevance. Is the cost and complexity of water purification worth it? Indeed, the water reused at the end of the treatment plant still contains nitrates and phosphorus. Doesn’t it make more sense to use this nutrient-rich water source for agriculture than to make it potable at a high price? Everything can be done with technology, even drinking water from wastewater. Honestly, though, at what cost?

How does the 1h2o3 Water REUSE skid work?

1h2o3 skid is an innovative system for reusing recycled water. It is working in a simple and efficient way. The goal is to filter and purify wastewater to make it reusable.

  • When opening the tap, water comes out under pressure.
  • Drop in pressure triggers pumping.
  • Pumped water is filtered and disinfected
  • A control valve allows the flow rate to be adjusted. Recommended operating flow rate will depend on the transmittance of the water source.
  • Once the filter is clogged, a solenoid discharge valve opens to discharge the particles.

We chose not to make drinking water. Indeed, 99% of REUSE applications require non-potable water. We just need it to be clean enough to reach the desired quality grades. 1h2o3 skid is therefore an ideal solution to reuse water in many applications such as irrigation, industrial cleaning and even production. It’s also intended to be easily integrated into existing systems. It can be used to treat wastewater generated by homes, public buildings or even factories. The system is cost-effective, significantly reducing drinking water costs while reducing wastewater disposal costs. Compact, it is designed to be combined with other 1h2o3 modular equipment to meet different water treatment needs. For an estimate of your project, please complete the design form on the skid page!

Presentation of the Water REUSE Skid and its function

Water REUSE skid reduces drinking water consumption for communities and businesses. With this system, you can create another non-drinking water network, which in our jargon is called an industrial water network.

It uses advanced technologies to purify industrial water, saving businesses both money and reducing their environmental impact. Treatment process includes pumping, filtration, disinfection and flow control. The skid is available in different sizes. Every company has a model that is adapted to its needs. In addition, the use of non-potable water helps to conserve freshwater resources by avoiding the need to tap into supplies.

Technologies used to recycle water

Reusing treated water is growing more and more popular to preserve our planet’s fresh water resources. However, concerns about recycled water quality can make people skeptical about using this method. That’s where the Water REUSE skid comes in, with its high processing performance and reasonable cost. REUSE skid is very simple. A single suction pump is able to draw in the water to be treated and load the skid. Automatic filtration ensures that impurities are removed from the treated water, resulting in clean, high quality water. Disinfection is completed by an automatic cleaning device. Manual regulation allows the flow rate to be adjusted to the user’s needs.

REUSE Skid's performance in terms of recycled water quality

With its process, the skid 1h2o3 can produce water quality of class A, close to potable water quality. It all depends on your transmittance in fact, so on the treatment performance of your treatment plant.Transmittance measures the quantity of light through a water sample. The more transmitter, the clearer and cleaner the water. ReuSE skid is very sensitive to the transmittance of the treated water. The clearer the water, the more water can be reused.

REUSE Skid’s performance is also related to the embedded fine filtration technology (20 microns). This allows us to achieve quality classes from A to D, at specific flow rates for each device depending on the quality of the resource.

Water reuse skid benefits

There are so many benefits to reusing water that it begs the question: why isn’t this technology more widely used?

With water reuse skid, you can save thousands and thousands of liters of water every day. Here are some benefits of 1h2o3’s Water REUSE skids:

  • Compactness: easy to install on new or existing projects.
  • Easy handling: with open structure for transpallet
  • High quality level: can reach quality A depending on the resource
  • High flow rate: up to 45 m3/h, the flow rate being adjusted to the transmittance
  • Simplicity: no calibration of sensors, the skid works autonomously once primed.
  • High quality and recyclable materials: unlike fiberglass, all materials used in our equipment are 100% recyclable.
