What are Entex Systems?
- Entex biological systems provide a surface for biological growth, which can optimize the bug populations needed for treatment of pollutants (i.e. BOD, TSS, NH3-N, TN).
- Entex filtration systems provide for removal of TSS as the water flows through the filter cloth during tertiary treatment.
Who is Entex?
A team of leaders answering today’s challenges while anticipating tomorrow’s solutions. As the only provider of both fixed media systems (BioWeb) and moving media systems (BioPortz) in both the IFAS and MBBR configurations, Entex offers an unbiased assessment and customized designs. The Entex team has been involved in over 750 installations with over a combined 100 years of experience. In its seventh year of operation, the same experienced team continues to support its customers.
Entex has a proven track record of delivering clean water solutions. Technologies provided by Entex have been selected with confidence to treat more than 60 million gallons per day (MGD) of design capacity, with installation ranging from 12 MGD to 15,000 gallons per day.
What local, state, or federal regulations do you follow and why can’t the water that’s recycled be used as drinking water? Wouldn’t that go further to solving water problems globally?
Living Machine® systems have been permitted in over a dozen states under federal and state laws and regulations governing wastewater treatment and reuse. These regulations prevent wastewater treatment systems from being used for direct wastewater treatment to potable (drinking water) use. Drinking water consumption is frequently a very small percent <10% of total water use. Therefore, technologies such as the Living Machine® can make a major impact on overall water usage.
Is a Living Machine® system safe? Are there any odors associated with the process or the effluent?
The Living Machine® is designed to protect health and operate safely and reliably. Wastewater is always below the surface of the Living Machine® system’s wetland media (crushed aggregate, or gravel) so there is no potential for accidental contact with partially treated effluent or the development of a mosquito breeding habitat. Second, the Living Machine® process itself minimizes odor generation. Odors are eliminated by careful design relying on simple odor removal mechanisms. A properly maintained Living Machine® system will have the pleasant smell of the plants used in the wetland, including flowers when flowering plants are chosen. Many Living Machine® systems have been built inside buildings, proving the effectiveness of odor control in these systems.
What types of customers have chosen the Living Machine®?
Commercial, institutional, and government clients are using Living Machine® systems for schools, resorts, zoos, office buildings and food processing operations.
Does the Living Machine® qualify for LEED certification?
Yes. The Living Machine® has been part of LEED certification efforts for several customers, including the new headquarters office facility for the Port of Portland in Oregon. The Living Machine® is part of their cutting-edge sustainable design for which they are seeking LEED Platinum certification.
Can customers save money with a Living Machine®? How would a return on investment be generated?
Customers save money by using the Living Machine®. Specifically, by:
- Avoiding sewer hook-up fees
- Avoiding cost of constructing sewer lines
- Reducing cost of water and sewer service
- Reducing energy cost
- Reducing operations and maintenance labor and cost
Immediate savings in addition to life cycle savings can be realized. For example, a school in North Carolina saved over $4 million in construction and sewer hook-up fees with a Living Machine®. WWT Engineers are experienced in helping clients identify and maximize the economic and financial benefits of Living Machine® systems.
How could a Living Machine® help solve water problems in water scarce areas?
By allowing water to be treated and reused multiple times, Living Machine® technology can dramatically reduce the amount of potable water required for certain applications. In fact, Living Machine® technology is capable of “sewer mining,” that is taking water out of an existing sewer pipe and reclaiming it for irrigation, industrial processes, and other non-potable uses.
What is the footprint and energy use of the Living Machine® compared to other treatment systems?
Small footprint is a characteristic of the Living Machine® tidal wetland. In a recent article in Ecological Engineering (Issue 35, 2009, pages 184-192), the authors compare traditional (activated-sludge) wastewater treatment and wetland technologies: aerated subsurface flow, tidal flow, and pulse-fed wetland treatment. The conclusions support our findings that the Living Machine® tidal flow wetland system provides the optimum combination of energy use and footprint requirements.
How does the Living Machine® Work?
The Living Machine® uses an engineered, packed bed containment that promotes the growth of dense, diverse ecosystems of microorganisms. Wastewater is introduced to the containment modules in computer controlled fill and drain cycles. The alternating aerobic and anaerobic conditions produce the same type of nutrient and oxygen cycles found in a natural tidal wetland. This complex natural system, enhanced and accelerated by technology, consumes the waste to produce clean water with no chemical additives or by-products.
What is a Living Machine®?
The Next Gen Living Machine® systems combine advanced technology and the natural ecosystem processes of a tidal wetland to create the wastewater treatment technology of the 21st Century. The Living Machine® applies ecological engineering to adapt and contain nature’s most productive ecosystem. The Living Machine® Tidal Flow Wetland encapsulates those ecological processes to create a modular system that is beautiful and safe as well as robust and reliable for treating blackwater, graywater, and storm water. Living Machine® is a patented and trademarked technology offered exclusively by Worrell Water Technologies, LLC (WWT).
How clean does the water get?
Water is always treated to the required standards set by authorities. It is important to note that water recycled within a Sustainable Water facility is not intended for drinking but for non-potable use such as within heating and cooling systems, as well as for irrigation and toilet flushing.
What are the size limitations?
There are no size limitations to the technology.
Is odor control incorporated into the design of the treatment plants?
The odorous processes are entirely enclosed in our designs and can be treated with biofilters. Even the process areas within the treatment plants are entirely odor free.
Do the plants treat the water?
The plants do not treat the water. Their primary function is to provide the habitat in their root zone for the myriads of organisms which thrive there. The microorganisms living in the root zone drive the reactions that help treat the water.
How does this technology help the environment and solve water scarcity?
Sustainable Water offers facilities much smaller than traditional wastewater treatment plants, so it can be placed in tight, urban areas. The solution is clean water in less space, for less money and energy, in a greenhouse that produces no odors.
