This paper discussed the transformation of the mechanical vibration (sound pressure) in the range from 85 dB to 140 dB into electrical energy (electric potential – voltage). Simulations that involved designing and determining the piezoelectric was conducted using COMSOL Multiphysics 5.3, whereas simulation of the harvesting circuit of the full-bridge rectifier was conducted by using Multisim. In the experimental work, a piezoelectric generator cantilever; aluminium cantilever with a lead zirconate titanate (PZT-5A) piezoelectric generator was built to extract sound energy from passing road vehicles. Results obtained from both simulation and experimental work were analyzed, suggesting that the piezoelectric transducer is capable for harvesting the vibration of sound from the passing road vehicles.This study was conducted to harvest the vibration of sound exists in our environment, as the energy harvesting circuit equipped with a piezoelectric transducer and a full-bridge rectifying circuit was designed and built.

The reuse of treated wastewater has become a practice employed more frequently in the recent years, particularly in irrigation purposes. However, the public perception on this aspect should be taken into consideration so that the effects on people’s comfort are minimised. This paper addresses the issue of treating livestock wastewater in order to meet the requirements for its reuse as irrigation water, also taking into consideration some parameters that may influence the public acceptability, such as odour and colour. Ozonisation is a proposed method for the advanced treatment of this type of wastewater. The results showed an improvement of physicochemical and bacteriological parameters adequate to the regulations regarding crop irrigation. The organoleptic properties of the final effluent have registered a decrease of colour intensity and odour up to acceptable values. Ozonisation has proved efficient in the treatment of livestock wastewater and although it involves high operating cost, it provides effluents that may be more easily accepted by the public for reuse in irrigation purposes near the living areas.Water is an essential but scarce resource and its preservation is one of the issues that have gained an increased interest in the last decades.
