Krofta Engineering

Papers mills are highly water-consuming plants and produce tons of wastewater every day. Wastewater treatment can be done with the Sedicell equipment of Krofta engineering. Our Sedicell equipment is very effective in wastewater treatment from paper mills and other plants. With this equipment, we can separate fiber present in the effluents and after this fiber and treated water can be used for different purposes.  Sedicell mechanism is based on the sedimentation of the fibers based on their density. Most of the fibres come on the surface of the water and rest settle down depending on their density. The fiber removed are of high quality and are reused n different plants as a raw material to synthesize different types of products. Paper mills have reduced water consumption in recent years •           In 1980 it was 250 cubic meter per ton of paper •           In 1990 it came down...

Since the establishment of industrial plants, all industry owners are facing the problem of treating wastewater produced during the refining of oil or production of other products. Effluents from these industries contain different harmful and toxic chemicals and should not be dumped directly into open. They first need to be treated properly using dissolved air flotation DAF mechanism before dumping. Kroftaengineering has developed an entire setup for the dissolved air flotation method which is totally designed with the scientific method and equipped with modern technologies, keeping in mind total removal of solid and oil particles from the effluents. In the setup consisting of a big tank, a shaft and a motor which rotates the shaft, air needs to be dissolved under high pressure into the wastewater leading to the formation of air bubbles which causes the solid particles and minute oil droplets to with them on the surface. From the surface, they can be easily taken awa...
