Gas Energy Mixing System Vs Dissolved Air Floatation
Dissolved Air Floatation system is relatively a common wastewater treatment and has been used for quite some time in industries and water treatment plants. Though DAF has several advantages but its disadvantages exceed its benefits in many cases. There has been a constant research and development in the water treatment industry to search for an alternate wastewater treatment solution which replaces the disadvantages of DAF system. One such alternative has been developed by Clean Water Technology Inc. namely GEM (the initials stand for Gas Energy Mixing) which is the most advanced primary wastewater treatment.
The major benefit of GEM technology is in its application on the existing DAF system, known as ‘DAF Retrofit’ which helps in deriving improved results. Industries and municipalities with pre-installed DAF system can derive the benefits of GEM system with DAF Retrofits. Second major benefit is the GEM system itself which is a better version of DAF in many ways. Here, it’s important to draw a comparison between DAF and GEM system in order to understand the efficiencies of GEM or DAF Retrofit over DAF. Given below are the points that’ll explain the comparison.
1) Contaminant Loading – Dissolved Air Floatation needs larger tanks to adjust to higher contaminant loading which involves capital expenditure whereas in GEM system increase in water conservation can be handled within the given tank size.
2) Waste Stream - The GEM system oxygenates 100% of waste stream in the beginning itself whereas in Dissolved Air Floatation system no aeration happen until waste stream hits the floatation tank.
3) Bubble Generation - In DAF system only 20% of waste stream aeration generate very less amount of usable bubbles whereas in GEM 100% aeration generates 1000 times more Nano bubbles.
4) Process - On the introduction of waste stream into the LSGM heads in GEM system, the polymers get uncoiled to attract higher percentage of contaminants whereas in DAF system the polymers remain coiled on the introduction of chemicals in the flocculation tubes and attracts only the waste particles.
5) Adaption to changes - GEM system can adapt to stream changes efficiently in less than a minute whereas any stream change in Dissolved Air Floatation system takes more than one hour to adjust.
6) Tank Size -The total cost depends a lot on the size of the tank. GEM technology can work with any size of tank as its usage is limited to skimming solids only. Whereas in DAF system larger tanks are required for heavier loads and flows.
7) Expansion - GEM system can easily expand without additional investment on capital whereas DAF system can expand only up to 20% before a larger system is required.
8) Design and Maintenance - GEM system has simple design with few moving parts that require minimum and easy maintenance whereas Dissolved Air Floatation system has a little complex design wise with moving parts that require heavy maintenance.
From the stated comparison, we can conclude the following disadvantages of Dissolved Air Floatation system:
It must be clear to the readers that how GEM system is more effective and an advanced replacement for DAF system and how GEM technology can help in addressing the shortcomings of DAF system.
