Gas Energy Mixing System (GEM)
The Gas Energy Mixing) GEM® System is an innovative and patented approach to wastewater treatment. The GEM System removes higher levels of contaminants than conventional dissolved air flotation (DAF) systems, using less chemicals, while generating significantly drier sludge. The GEM System footprint is typically over 50% smaller than a typical DAF (dissolved air flotation) of similar capacity.
The GEM system utilises a unique approach to flocculation and floatation technology and outperforms other dissolved air flotation (DAF) systems. Instead of relying on a random collision process, the GEM System technology manages it by dissolving air into 100% of the waste stream.

removal efficiencies of total suspended solids (TSS), fats, oils and grease (FOG), and the suspended portion of chemical oxygen demand (COD) and biological oxygen demand (BOD).
The patented LSGM (Liquid Solid Gas Mixing) technology utilises specialized cartridges to generate energy and achieve complete air mixing throughout the entire waste stream. By efficiently separating solids from liquids, it effectively prevents their entry into the skimmer tank, ensuring optimal performance. The LSGM’s use hydrocyclone / centrifugal energy to provide extremely high energy mixing of waste water, oxygen and polymers. 100% aeration/oxygenation generates 1,000 times more NANO bubbles. The tank is only used for skimming solids and therefore can be very small.
The GEM footprint is 30 – 90% smaller than a conventional DAF’s footprint for the same throughput.
CWT GEM® System Advantages:
- Better contaminant removal rates than DAF systems.
- Adaptability – the GEM System adjusts to higher flow rates and higher contaminant levels without equipment changes.
- Less chemicals – uses 20%-80% less chemicals than DAF systems.
- Smaller Footprint – uses less space than other flotation and flocculation systems.
- Drier Sludge – the technology of using long chain polymers produces drier sludge (8 to 13% drier and over 20% after decanting.)
Dissolved Air Flotation
The MAK Water Dissolved Air Flotation (DAF) system is a superior counter current system designed to achieve maximum treatment efficiency in a compact footprint. It is able to remove a variety of contaminants to meet trade waste or reuse requirements. Each system is sized based on the hydraulic loading rate, Total Suspended Solids (TSS) and Fats, Oil and Greases (FOG) levels. The surface loading rate that can be applied is dependent on each application.
STANDARD PROCESS
The DAF separates the suspended solids and lighter liquid contaminants (eg FOG and hydrocarbons) from the water by moving them to the surface of the DAF vessel and then scraping them off the surface. A pressurised stream of airsaturated water is mixed with the flocculated water and with the release of pressure, a cloud of very fine air bubbles carries the suspended solids and lighter liquids to the tank surface. Clean water overflows from the DAF tank, via an under/over-weir to sewer or to the next stage of the treatment process. The overflow level is adjustable and controls the level in the DAF flotation section. The sludge on the surface of the DAF is scraped into a sludge hopper by a mechanical scraper. The DAF system is automated via a programmable logic controller (PLC) mounted within a control cabinet on the system.
