The Megacell is our rectangular DAF with lamella plates inside. It is designed to handle high solids loading and high flow rates and offers increased surface area due to the presence of the lamella plates. It has a chain and scrapper mechanism which pushes the top layer of scum to one end which is later removed with the help of a paddle wheel. The bottom conical shaped hoppers store the settled sludge which are removed periodically from the system with the help of timer activated purge valves. The floated scum is pushed to one side with the chain and scrapper mechanism and the paddle as wheel removes the scum from the top. It is designed to have a retention time of 7-10 minutes. It can handle a range of flow rates as low as 10 m3/hr up to over 1000 m3/hr in a single unit. Megacell started out as a revolutionary DAF to increase the efficiency of the recovered fiber in paper mills. After several successful installations it is now running in various industries, most popularly for sea water desalination applications. Main Advantages Low Operation Cost, low power requirement and minimal manpower intervention required Higher Capacity Product can handle high flow rates in a single unit Low Footprint, fully metallic structure with minimal to no civil construction required and is highly compact Low Installation Cost, plug and play type system Highly efficient unit * (*Subject to proper operation and maintenance as mentioned by Krofta Engineering Limited) Popular Applications Pulp & Paper Sea water and River Water Desalination Power plants Oil and Gas Refineries Abattoirs and Meat Processing Steel Mills  

The minicell is the operationally simplest circular DAF model. It was developed especially for effluent having difficult and fragile solids and oil. Another special technical offering of the minicell is the three different height options available depending on the application, flow rate and solids loading. It has a scoop-type system to remove the floated sludge. The minicell is the operationally simplest circular DAF model. It was developed especially for effluent having difficult and fragile solids and oil. Another special technical offering of the minicell is the three different height options available depending on the application, flow rate and solids loading. It has a scoop-type system to remove the floated sludge. The bottom sludge is directed to one side with the help of wiper blades and removed periodically with the help of timer-activated purge valves. A single unit can handle a flow rate as low as 16 m3/hr and go as high as 712 m3/hr. Main Advantages Low footprint, fully metallic structure with minimal to no civil construction required and is a compact unit Competitive pricing as compared to traditional larger height circular DAF units 3 height options available for the most efficient performance based on the inlet characteristics Simple operation, installation and maintenance Excellent efficiency for suspended solids and oil removal * (*Subject to proper operation and maintenance as mentioned by Krofta Engineering Limited Popular Applications Food and Beverage Dairy Automobile and paint shops Chemical and Pharmaceutica

The Sedicell is a mechanically simple, yet robust circular DAF. It can be constructed in a civil tank for longevity and high flow rates, with wetted parts manufactured in metal, or the entire DAF can be constructed in metal as well. It has a spiral scoop system to remove floated sludge. Sedicell has a retention time of around 30 minutes due to its height, hence it is perfectly suited to handle very high solids. This also leads to a high sludge blanket formation with high sludge consistency, making the sludge easier to handle for further de-watering processes. Sedicell has been supplied successfully as a secondary clarifier as well for colour and TSS removal in pulp and paper applications. The largest single unit of Sedicell can handle up to 2000 m3/hr flow. Main Advantages Sedicell is a low sensitivity clarifier and has the ability to deal with variations in inlet flow and shock loading, and will continue to provide high efficiency removal. Due to its height, the Sedicell has a retention time of 30 minutes and provides for better sedimented solids removal It has a civil constructed base for longevity of use Popular Applications Pulp & Paper Biological Sludge Clarification Sludge Thickening Municipalities and CETP Chemicals

The supercell is Kroftas original and flagship DAF model. It has a smaller surface area for its capacity because it attains a very specific clarification degree. The water level in the tank is lower than all other Krofta DAF models. Supercell has a retention time of just 3 minutes due to its tank height of 600 mm. It has a spiral scoop system to remove floated sludge and the wiper blades direct the settle sludge to the built-in sump which is dispersed periodically with the help of timer activated purge valves. MAIN ADVANTAGES Low installation cost due to completely metallic manufactured structure Minimal height requirement. Multiple Supercell DAFs can be seen stacked on top of each other with a minimal gap to optimally use space Low cost due to minimal load factor and small tank height, when compared with similar performance clarifiers POPULAR APPLICATIONS Pulp & Paper Tanneries Dairy Edible Oils

Unicell is a horizontal DAF with strong mechanical components to provide efficient sludge removal and clarification of heavy and fatty effluents. It is designed to accommodate lower flow rates with high efficiency. The floated scum is pushed to one side with the chain and scrapper mechanism and the paddle as wheel removes the scum from the top. It is designed to have a retention time of around 30 minutes. It can handle a range of flow rates as low as 10 m3/hr up to 170 m3/hr in a single unit. The bottom conical-shaped hoppers store the settled sludge which are removed periodically from the system with the help of timer-activated purge valves. MAIN ADVANTAGE High retention time of around 30 minutes to deal with high solid loading Special hydraulic design to allow efficient operation with minimally optimized or no chemical dosing Very efficient surface and bottom sludge removal systems allowing for high inlet solids Top sludge chain scrapper system gives high floated sludge consistency
