Krofta Engineering

  KROFTA Developed the concepts of Dissolved Air Floatation Technology. and has been active in water treatment and clarification since 1983. Among the raw materials waste Paper factory equipment processing is significant. Because Paper fiber recovery can contain dust, sand, wire stapler pins, clips, the processing is significant.

  Sludge dewatering  is the practice of minimizing waste by volume to prepare for its effective disposal.  Dewatering  the  sludge  with a  dewatering  filter press significantly reduces its weight and its volume before disposal. Digested  sludge  is put through large centrifuges that work in the same fashion as a washing machine spin cycle. The spinning centrifuge produces a force that  separates  the majority of the  water  from the  sludge  solid, creating a biosolid substance. Wastewater treatment involves several key components: physical treatment (i.e. screening and filtering processes), biological treatment (i.e. oxidation ponds and lagoons), and chemicals. The chemicals required for water treatment must be used more aggressively and in larger quantities for wastewater than municipal drinking water. As such, safe, proper storage for wastewater treatment chemicals is critical.

  Unicell- Dissolved Air Flotation Clarifier The simple and basic concepts with strong mechanical components provide efficient sludge removal and clarification of heavy and fatty effluents. Unicell dissolved air clarifier was developed at the top of the sixties and therefore the beginning of the seventies. Like most of the products of the corporate, it had been used for clarification mainly within the paper industry. The Unicell design was designed for giant water flows and concrete tank construction. within the early 2000s, the Unicell concept was adapted to small units with chrome steel tanks to be utilized in the food industry for heavy oil and grease removal. The clarified water extraction was simplified (the bottom clarified water recovery pipes disappeared) and therefore the surface scraper was complemented by a paddle wheel to enhance the floated sludge removal capacity. By the center of the last decade, the market demand for giant seawater and water DAF clarifiers increased...

  The  Minicell  is the simplest and the smallest DAF clarifier. The  Central driven Clarifier  has a special drive unit that 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. Main Advantages:- Very Competitive price simple operation Excellent Performance with "difficult" and "fragile" sludge quality. - the sludge blanket does not move and the risk of having "sinking flocs" is negligible (the sludge is not pushed to the sludge extraction device as the spiral scoop is traveling around the sludge blanket). Three different tank heights available(choice according to the application) Main applications : Excess biological sludge clarification and thickening before further de-watering (for small installations) (excellent application in case of biological phosphorous removal. This reduce also the polym...

  The "KROFTA" SUPERCELL has a distinct edge over other systems when the sludge or water is recycled to the process and where the type of waste water varies. For Pulp and Paper Industry the small volume and short retention time are extremely important, where the supercell is used as a save-all and in the drinking process. 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, th...

  Sedicell  is a mechanically simple and robust Dissolved Air Floatation clarifier that 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. After the separation of these particles, clear water present between the zones of floated and settled solid particles is subsequently discharged into the overflow of an adjustable weir. Performance HIGH CLARIFICATION and reduction of filterable suspended solids are obtained to meet Pollution Control Authority requirements. SLUDGE CONSISTENCY, maintained by the intermittent operation of the scoop along with adjustments of the tank water level, average 3-6% FLOCCULATING CHEMICALS can be added in several places depending on the effluent. Remova...
