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.

  The treatment of water and wastewater using electrocoagulation (EC) is a newer method. It combines the benefits of electrochemistry, flotation, and coagulation. Electric current is used in an electrochemical procedure to eliminate dissolved, emulsified, or suspended contaminants from water. Because it is an environmentally benign choice that may create the least sludge, requires no chemical additions, and has the smallest footprint without impacting the water quality after treatment, electrochemical wastewater treatment technology has started to recover attention.     P rinciple of electrocoagulation   It's essential principle is based on how water molecules respond in a redox reaction to a strong electric field. In the process of oxidizing the anode material, coagulating agents are released, forming metal hydroxide complexes that neutralize particulate materials and produce agglomerates.     Working    A number of processes happen at once when...

Screw Press Krofta Screw press is an economical and eco-friendly sludge dewatering machine. It is a new type of sludge extrusion dewatering equipment by using the principle of screw extrusion, through the strong squeezing force generated by the change of screw diameter and screw pitch, and the tiny gap between the floating ring and the fixed ring, to realize solid-liquid separation. Typical applications for wastewater treatment plants include dewatering of thickened or un-thickened waste-activated sludge (WAS), digested sludge from aerobic or anaerobic processes, and dissolved air flotation (DAF) sludges. Krofta Screw Press is also suitable for dewatering of liquid sludges from a wide range of industries, including and municipalities. For municipal /bio sludge applications, Krofta Screw Press typically produces dewatered sludge cake of 15% to 20% dry solids content.
