Abstract: The invention relates to a municipal wastewater treatment system (STAR) for forming a wastewater treatment plant (PTAR), characterized by the functional and structural relationship between the components thereof. The invention comprises seven treatment stages in the STAR and the arrangement thereof, including: an intake regulator box having a discharge outlet; a pretreatment stage consisting of solid separation screens and grit channels; and anaerobic biodigester; an up-flow anaerobic filter; drying beds; subsurface flow constructed wetlands; and a chlorine contact channel. The STAR and PTAR according to the invention are suitable for use in a single home, as well as for use by communities of approximately 5,000 (thousand) inhabitants, and their capacity can be increased to the extent that new elements are provided at each of the different steps, simply by adding and adapting modules, without having to replace the already operating elements.

Abstract: A device for reminding a driver of a vehicle of the expiration date of the associated inspection sticker. The device includes a housing, a microprocessor, a LCD, a calendar chip for generating a date, a clock chip for generating a time, an alarm chip the provides a visible alarm and an audible alarm, a select button that selects either the clock chip, the calendar chip, or the alarm chip, and a value button that sets either the clock chip, the calendar chip, or the alarm chip that was selected by the select button. The device further includes a piece of two-sided tape that is attached to the rear wall of the housing and attaches the housing to the windshield of the vehicle, behind the inspection sticker. The audible and visible alarms have duty cycles with frequencies and durations that are selected by a menu brought up on the LCD display by the select button and set by the value button. The duty cycles are intermittent as opposed to constant for preventing drain on the battery.
