  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.

  WIP management solutions range from small, highly focused measures like as inventory management to extensive, end-to-end projects incorporating system linkages and process automation. The ultimate goals of any of these solutions are to keep WIP flowing efficiently, eliminate unnecessary inventory accumulation, and support several production objectives at the same time. While narrow-scope solutions yield efficiency and benefits, WIP management strategies that provide insight throughout the whole supply chain yield the best outcomes.  A comprehensive approach to WIP management entails multiple layers of well-integrated business IT solutions to achieve end-to-end visibility of core business processes such as production, procurement, and distribution, as well as insights into business resources such as cash, raw materials, production capacity, customer orders, purchase orders, and human resources. This structure often contains an ERP, a manufacturing execution system (MES), and ...

  The MBBR is a highly successful biological treatment technique that combines traditional activated sludge with biofilm medium. Within the aeration and anoxic tanks, the MBBR process employs floating High-Capacity Microorganism Biochips medium. Organic material is consumed by the microbes. The medium increases the surface area available for biological microorganisms to stick and grow on. The increased surface area minimizes the footprint of the wastewater treatment tanks. The treatment procedure might be aerobic or anaerobic, with large volume loads.   MBBR Advantages   Small units with a compact area   Enhanced treatment capacity   Complete elimination of solids   improved settling properties   Higher suspended biomass operation   Long sludge retention durations due to high concentrations   Process stability has been improved.   Head loss is minimal.   There is no filter channeling.   There is no need for frequent backwashing...

  Lamella Clarifier  is a solid liquid Separator based on Sedimentation Process. The entire space in the clarifier is segregated into numerous integral sections or chambers. There are several blades fitted in the clarifier with their one side provided with settling surfaces. The operation mechanism of the  Lamella Clarifier  is as the following: Untreated inlet Waste Water Stream enters the  Lamella Clarifier Water longitudinally transverses through feed ducts along the tank Solids are now separated and descend onto settling surface provided by the blades Slide down continues to Collection hopper. Clarified water collected all across the Lamella Clarifier Section through perforated double wall PVC Pipes. Water level maintained up to the top of internal PVC Pipes. Clarified water through the central PVC weir Tube enters the V-Notch Chamber through the bottom Flocculation aid like Polyelectrolyte is used to enhance the binding efficiency of the flocs, their settle...
