Dissolved air flotation
(DAF) is a technique that could be used as an internal cleaning stage to remove these substances.
The ITS improves the sustainability of fracking by offering a unique approach to water treatment, combining customizable chemical treatment and a powerful, proprietary dissolved air flotation
system design that removes up to 99% of harmful solids from virtually any type of frac water.
Facility To The Existing Dissolved Air Flotation
Aquatech also supplied dissolved air flotation
technology to protect the plant from seasonal red tides -- also known as harmful algal blooms (HABs), which can cause a number of problems from affecting the taste and odor of the water to restricting plant operations or even shutting down a desalination plant.
The Ghubrah facility incorporates submerged seawater intake and outfall, dissolved air flotation
, dual media filtration, cartridge filtration, double pass reverse osmosis and remineralisation through carbon dioxide and lime dousing.
However, larger bubbles cannot remove small particles and dissolved air flotation
still produces wastewater with much better contaminant removal efficiencies.
PACE plans to replace the early stages of chemical flocculation and dissolved air flotation
with OriginOil's process, potentially improving the performance and scalability of on-site water re-use, and reducing both capital and operating expenses.
Improvement/rehabilitation of existing dissolved air flotation
From there, the waste water is processed through a Dissolved Air Flotation
(DAF) unit before being treated by both aerobic and anaerobic biological treatment.
Polishing after an existing dissolved air flotation
(DAF) unit (using a microfilter, for example), producing a super clear water quality;
The Algae Harvesting Technology Optimized (AHTO[TM]) system, from World Water Works, is a patent-pending version of the company's wastewater industry high rate Dissolved Air Flotation
(DAF) process, specifically tailored to Algae Harvesting.
Xylem will provide its dissolved air flotation
system, Leopold Clari-DAF and its Leopold Type S underdrain solutions for the project.
