Advanced DAF system Krofta

Advanced DAF system Krofta
Krofta clarifiers have retention times as low as 3 minutes and with a possibility of resource recovery in some cases as opposed to the sedimentation methods characterised by very long retention times. Krofta, is the world leader in this field having more than 1200 installations running successfully all over the world. The advanced DAF system offered by Krofta does not warrant a separate flocculation tank, flocculation mixer, flash tank and flash mixer. The Air Saturation Tank of yesteryears is replaced by the patented Krofta Air Dissolving Tube (ADT) which provides effluent saturated with air in residence time of 10 seconds. Air requirement is also very low as compared to the DAFs of earlier designs. Salient features / benefits of Krofta DAF clarifiers are: Total steel fabrication and negligible civil work facilitating relocation, if needed. Pulp and Paper Industry download Company Profile

Sedicell-Dissolved Air Flotation Clarifier Sedicell is a mechanically simple and robust Dissolved Air Floatation clarifier which allows simultaneous removal of floatable and settable solids from suspensions in water for high clarity. Firstly, the raw water enters the central distributor and blends with air released from air carrier water. After this, the air bubbles carry the flocculated solids to the water surface and the Heavier particles settle at the bottom of the tank floor. Paint Making Machine A wide range of raw materials are used in paint industry such as- resins, solvents, pigments, drying oil and extenders. Closely examine the process of making paint; water as constituent is only used in making water based paints and cooling of sand mill engaged in producing oil paints. The paint sludge contains solvents and residues which are toxic metals like mercury, lead and Chromium. Here the application of DAF technology The waste water obtained from the paint industry is alkaline in nature and contains some oil, grease, BOD, COD and suspended solids. BOD and COD levels are only parameters that give us a rough idea of organic waste.

Supercell - Dissolved Air Flotation The most up-to-date clarifier based on this principle has been successfully used since 1973 for fibre recovery in paper mills and for a variety of solid / liquid separation processes. Worldwide Installation of more than 3,500 supercells and installation of over 300 units in India alone, speak for the reliance placed by reputed industries and municipalities on the efficiency of Krofta equipment. The Concept of dissolved air floatation for removing solids from liquids was perfected by Dr. Milos Krofta of U.S.A. DAF technology provide the concepts of supercell methods used for wastewater streams in process the property with different various characteristics, the Krofta engineering offers the supracell concepts for clarification, thicker sludge consistency and low retention. The technique used on number of industries including food and beverage, pulp and paper, wineries and distilleries, and municipal wastewater.

Oil Water Separators for Wastewater Treatment-kroftaengineering We have made a technical collaboration with Stetfield Separators Limited,UK for their Oil Water Seperator like CPI & TPI to market their equipments in across the globe. Our Oil Water Separators are designed as per following specifications: Corrugated and Tilted Plate Separators Stetpack tilted or corrugated plate interceptors offer enhanced gravity separation of immiscible liquids via inclined parallel plates and coalescing media. Minicell-Dissolved Air Flotation Clarifier The clarifier has a special drive unit which is fitted to the shaft or cage. This cage or shaft can be provided with an overload sensor, if required by the client. By means of the shaft or cage, scraper arms with scraper blades are connected to the drive unit.

Desalination of sea water Desalination embroil eliminating dissolved minerals from sea water and saline water (a mix of fresh water and marine water) and is gradually vital spring of fresh water. Krofta Engineering Ltd designs pre-treatment sea water desalination units for effective and competent desalination. DAF seawater pre-treatments a gravity focused solids liquid separation procedure. DAF is a developing procedure for the clarification of seawater prior to desalination by reverse osmosis. The success of DAF relies on the measure of bubbles and particles moving through water, and to the dissolution and precipitation of air. The performances of the DAF system will be inspected by measuring: -Turbidity, suspended solids, TOC, and pH

Leading manufacturer and supplier of water treatment plants India Pressure Filter is a closed cylindrical vessel either vertical or horizontal (mostly vertical) containing the filter media over a collector system. Water flows from top downwards percolating through the media and is drawn off through the collector system at the bottom. Cycle of operation include back washing with or without air scouring, short rinse to waste and return to operation.

Tannery and sludge Industry Tannery industry requires efficient DAF sludge handling system for its animal fat waste products. DAF technology is widely used in animal/food processing/meat/slaughtering applications to eliminate SS (suspended solids), fats, grease and oils from various samples of wastewaters. The elevated rates of processing, lesser footprints and suppleness in procedure has been always appreciated and has taken advantage of these applications. The DAF technology utilizes air to generate micro bubbles which helps in attaching the solids to float onto the surface to be thrown away. Dissolved Air Flotation is principally for solid to liquid or liquid to liquid separation. Large amount of micro bubbles produced by dissolving and discharging system stick to solid or liquid units with same density as tannery waste water to make the entire sludge float to the surface thus attaining the purpose of solid to liquid or liquid to liquid separation.
