Abstract: The present invention relates to provide a carbon bed electrolyzer (CBE) unit for electrochemical treatment. More particularly the present invention relates to the treatment of recalcitrant wastewater, e.g. from chemical industry. Further the said CBE unit is useful for electrolytic treatment of liquid effluent having very high concentrations of Chemical oxygen Demand (COD), Total Kjeldahl Nitrogen (TKN) and Biochemical Oxygen Demand (BOD), and Total Dissolved Solids (TDS), and for improving biodegradability of the effluent. More particularly, the present invention relates to an electro oxidation process wherein the carbon bed gets regenerated in-situ continuously.

Abstract: A supply identifier takes precise decision on the range of the external supply to manage a proper internal supply to the core of the IC by controlling a regulator or a switch connected to external supply. This supply identifier defers the decision until everything that influences the decision settles after power-up, then makes a decision only once depending on the external supply range and switches itself off, keeping the decision stored, to avoid noise-induced wrong behavior and to reduce power consumption.

Abstract: A digital clock modulator provides a smoothly modulated clock period to reduce emitted electro-magnetic radiation (EMR). The digital clock modulator includes a plurality of delay elements connected in series and receiving as an input an unmodulated clock signal. A multiplexer receives inputs from unequally spaced taps between the delay elements. A control block provides selection inputs to the multiplexer, and receives the unmodulated clock signal from the delay elements. The delay elements include a last delay element providing the unmodulated clock signal to the control block. The last delay element has a predetermined delay for ensuring that the delay elements and related signal paths are in a same stable state before control to the multiplexer changes.

Abstract: A circuit includes a differential amplifier having a folded cascode architecture with a pair of cascode transistors. A sensing circuit senses a common mode input voltage of a differential input signal applied to the differential amplifier. A bias generator circuit generates a bias voltage for application to the pair of cascode transistors in the folded cascode architecture. The bias generator circuit is connected to an output of the sensing circuit such that the generated bias voltage has a value which is dependent on the sensed common mode input voltage. This dependence stabilizes a common mode output voltage from the differential amplifier in response to changes in the common mode input voltage.

Abstract: The improved circular secondary clarifier of the present invention requires less surface area and low HRT and provides efficient solids-liquid separation. The improved clarifier has better SS and BOD reduction and provides high under flow solids concentrations, as compared to conventional secondary clarifiers. The improved clarifier is even capable of treating wastewaters containing low MLSS concentration. One of the biggest advantages of improved clarifier is that it does not require a separate sump cum pump house as it removes the settled sludge using suction mechanism thereby reduces capital and recurring cost. Further, it provides natural flocculation, which is essential for agglomeration of solids and increases particle size referred to as ‘floc’ and eliminates provision for a separate flocculation facility thereby reduces capital and recurring costs.
