Abstract: The present invention generally relates to a system for treating effluent water. More particularly, it provides a robust apparatus for treating waste liquid by optimizing solar and wind energy to maximize the evaporation rate as compare to natural evaporation rate. The main object of the present invention is to provide a system for evaporating RO reject and other effluent liquid and other liquids, by optimizing system to solar and wind energy to maximize vaporization rate and recovery rate at marginal operational cost.

Abstract: A leak proof, completely sealed solenoid valve, comprising a housing 14 having a fluid flow path controlled via an electrically operated mechanism to control a flow; the mechanism comprises metallic coil 20 coiled around a bobbin 16 supported by a magnetic bracket 24 with terminal pins 18 connected to the bobbin 16 for receiving electrical input to facilitate an energized and de-energized state to control the movement of a poppet 34 shaft that obstructs the flow; wherein, the bobbin 16 comprises micro-melting fins, thereby housing over molding creates strong bond between two materials; a permanent weld is created between the bobbin 16 and the housing 14 to prevent internal leakage; and the completely sealed solenoid valve limits emissions and evaporations of the volatile fuel components into and from the valve, and contribute to reliability and robustness of the product by completely sealing the nozzle and housing using laser welding.

Abstract: A vacuum pump for automobiles used for brake application is provided wherein a method of reducing power consumption and running torque in a vacuum pump of a motor vehicle is explained. The present invention also provides a vacuum pump for automobiles comprising an actuator, a new vane locking assembly, a new vane and rotor assembly, a new non return valve assembly, the controlled oil supply means and a reed stopper assembly that reduces power loss and unnecessary frictional forces and to maintain a controlled oil supply to the vacuum pump.
