Green: Leed Credits and Water Reuse

Whether through rain harvesting, water reuse or energy savings (HVAC), Vortisand filtration systems will help you earn LEED credits and water savings for your building.

looking to upgrade your existing building?

Vortisand represents a great opportunity to obtain LEED -EB (Existing Building) credits, specifically regarding credit eAc1 (Optimize Energy Performance). Our system can achieve up to 20% energy savings due to its efficiencies in reducing biofouling and scaling (in cooling tower & HVAC applications). Ultimately increasing heat transfer efficiency and maintaining the equipment's original design efficiency.

Vortisand systems can also help your team of water professionals expand and grow their water reclaim and reuse objectives. Lets give water a second chance!

​Water reuse - A Positive Impact

The trend for sustainable building design and operation is increasing. The many possible applications of Vortisand filters multiply the opportunities of making your project greener. These include: rainwater polishing, water treatment for irrigation, HVAC water filtration, water reuse etc.

Most of the LEED credits that can be achieved involve energy related savings, one of the many advantages our cross-flow & microsand technology provide. Rainwater polishing and other water reclaim and reuse initiatives can also help contribute towards LEED credits.

Rainwater Polishing

Our high efficiency microsand filtration system is the perfect solution to completing your green building application. A storage tank side stream filtration design is the most efficient design, as the filter can be minimally sized with intermittent filtration flow. City water can be introduced to maintain a minimal water level (low level switch sends a signal to BAS). Water stored can be used for toilets, cooling tower makeup, irrigation and other non-potable water applications. This places the Vortisand system in a unique category of high efficiency water filters, thus outperforming todays traditional media filters!

 Water Recycling, Water Reuse & Reclaimed Water

​Recycled or reclaimed water is wastewater that has travelled through an advanced filtration system, removing solids and various harmful contaminants, to be used once again for a new purpose. Once the recycled water serves a purpose and applied to a second application, the process is referred to as water reuse or water recycling. Recycled water that is not being repurposed is still referred to as reclaimed/recycled water.

Sources for recycled water can come in various forms of wastewater, here are the common sources for water reuse applications;

  • Rainwater

  • Stormwater

  • Greywater

  • Treated effluent

 Two Basic Forms Of Water Reuse

​Given the critical shortage of drinking water in many regions, advanced treatment and reuse of reclaimed water is becoming increasingly common as municipalities, industrial manufacturers and many other industries address current water demands. Water reclaim and reuse offers many resource and financial benefits that can be applied to all industries. With today's technology, a water management plan focused on water reuse can be created and tailored to meet the water quality requirements of your water reuse project. Below we explore two basic purposes of using reclaimed water sources.

Indirect Potable Reuse (IPR)
Indirect potable reuse of wastewater is widely practiced for municipal and agricultural irrigation, dust suppression and urinal flushing.  In a number of US coastal regions, reuse water is injected into the ground.  This technique is called Aquifer Storage and Recovery and is utilized both to prevent saline incursion into freshwater aquifers.

Direct Potable Reuse (DPR)
In certain parts of the world, direct potable reuse is now the norm for recovering drinking water from waste streams.  This requires advanced treatment technology to remove Compounds of Emerging Concerns (CEC'S), Synthetic Organics (SO's), Endocrine Disruptor Compounds (EDC's) and Personal and Pharmaceutical Care Products (PPCP's), as well as various taste and odor compounds from water.

 Common Water Reuse Applications

​Landscape Irrigation

The use of recycled water for irrigation purposes conserves fresh water resources by replacing drinking quality water with recycled water. When used to irrigate residential areas, golf courses, school yards, fountains and parks, such recycled water receives treatment so that it is not considered a threat to public health.

​Agricultural Irrigation

By tapping into the nearest available sources of recycled water, todays farmers can now protect themselves against future droughts, interruptions in water supply and drastic increases in water costs.

​Potable Water

Potable water reuse projects use highly treated reclaimed wastewater to increase the supply of drinking water. Potable water reuse projects require advanced water treatment systems to remove dangerous contaminants, ensuring your recycled water meets drinking water standards and other appropriate water quality objectives.

​Industrial Uses

The use of recycled water is of adequate quality for many industrial applications. Common industrial applications for recycled water include; cooling tower loops, process water, boiler feed, washing and transportation of material.
