Introduction Water is essential for human life as it comprises 70% of the human body, from domestic applications to industrial and agricultural use. Clean and sustainable water is required and therefore an efficient and low cost method of treatment is required. High rate water clarification and filtration are fundamental to the purification of water sources for domestic and industrial applications. For more than 100 years, water treatment companies have been treating water through filtration and clarification processes. For instance, companies like Siemens Water Technologies and Infilco Degremont offer high performance wastewater, sludge and water purification solutions for whichever population and practically every influent condition. Over the years, different water clarification techniques have been developed for example high-rate dissolved air floatation (Aquadaf), high-rate clarifier and thickener (DensaDeg) and solids contact clarifier (Infilco, “Aquadaf” p 1). In this study we will focus on Aquadaf technology to explain how the high rate water clarification process works, the efficiency of the process and the economical aspect of it. Aquadaf technology is a high-rate clarifier for algae-laden and low turbidity surface water. These Aquadaf plants are exceptionally engineered waste matter collection system that offers working rates unparalleled by conservative flotation technologies (Infilco, “Aquadaf” p 2).In brief, Aquadaf technology generates an exclusive flow pattern that leads to amplified bubble plane area for greater floatation and loading turn over to more than ten times as compared to usual DAF systems. The outcome of this technique is low energy consumption, lower costs of operation and high capacity for new and existing treatment plants with no negligible space required (Infilco, “Aquadaf” p 2). Aquadaf Main Features It is a compact footprint of unit tallness of 10 -14 feet and 10-20 gpm/ft 2 loading rate and made up of stainless steel reprocess system. For this system, it has no or just limited polymers and consist of perfect membrane pretreatment machinery and further mechanical or hydraulic sludge removal alternatives. Beneath this system, there is retrofit sedimentation basins and wall layout. Never the less, Aquadaf technology has variety layout plans and can be tailored to any given size plan. Finally this system can easily be started up or shut down within few minutes (Infilco, “Aquadaf” p 3). How It Works The following are the six stages explaining how the high rate water clarification (Aquadaf technology works). Raw Water Inlet For high-rate dissolved air floatation technique, we have coagulated or viscous water coming in from a rapid mixer goes into a flow supply channel before going to the flocculation zone. These colloidal particles are destabilized by use of a coagulant such as ferric chloride hence facilitating particle aggregation. Once aggregation has been achieved, coagulated water is then pumped into flocculation zone (Infilco, “High-Rate Dissolved Air Flotation System” p 3). Flocculation Zone With the use of frequency mixers and tapered energy, coagulated water is uniformly divided to each unit and retained in this flocculation zone for about 8 to 10 minutes. The weakened particles agglomerate or comes together and results into bigger floc particles. As we know, technically the Aquadaf flotation process needs only the developm
