Waste Management’s Atlantic Landfill RO Concentrate Evaporation Project Short Listed for 2022 GWI Industrial Project of the Year
This project utilizes Dynatec’s MBR and RO. The reject from the RO is evaporated using waste heat from the on-site power generation. It is a great project overall and this is a cost effective and sustainable approach to handling RO reject.
WAVERLY, VA – WM’s 120,000GPD leachate evaporation project, developed in partnership with Heartland Water Technology, was shortlisted for the Global Water Intelligence’s 2022 Industrial Project of the year. A 120,000GPD (450m3/d) evaporation solution for reverse osmosis (RO) concentrate at the Waverly landfill site in Virginia, US., this project addresses the challenges of RO concentrate waste stream treatment and disposal.
Dynatec specializes in extensive industrial reverse osmosis (RO) membrane systems and nanofiltration (NF) membrane systems to remove soluble components of wastewater that may not have been removed by primary treatment. In most cases, the purified water can be reused.
RO is capable of rejecting soluble constituents of aqueous streams, such as:
- Bacteria
- Salts
- Sugars
- Proteins
- A wide range of organics and colors
- Improves the color, taste and properties of the fluid
This process is commonly used to purify water and remove salts and other impurities. It can be used to purify fluids such as ethanol, which will pass through the reverse osmosis membrane, while rejecting other ions and contaminants from passing.
Industrial Reverse Osmosis/Nanofiltration systems
The most common use for reverse osmosis is in purifying water. It is used to produce water that meets the most demanding specifications. This differs significantly from other RO systems that are often only designed to treat potable water. Our system is specifically designed to accommodate:
- Minimize reject volume
- Variable characteristics
- Minimize fouling
RO and NF Technology
RO uses a membrane that is semi-permeable, allowing the fluid that is being purified to pass through it, while rejecting the contaminants that remain. Most NF and RO systems are operated in crossflow to allow the membrane to continually clean itself.
Integrated clean-in-place (CIP)
The membrane skid has an integrated CIP system on the skid. This is especially important for wastewater reuse systems because the cleaning frequency of the skid is often higher than in other RO applications. With an integrated CIP system, cleaning is fast and easy, minimizing the operator’s time.
