Method of Wastewater Treatment using Renewable Energy

Abstract

Treatment of wastewater and particularly relates to a technique for wastewater treatment using renewable energy (RE) which is sole solar energy (SE). In bench scale experiment, a device is constructed to consist of two fixed upper and lower glass Petri dishes. Another device consists of plastic containers and both devices with the same volume of wastewater in the upper and distilled water in the lower container. The first device is placed on the bench beside window to be exposed to sunlight at room temperature and the other device is put outdoors under direct sunlight during daytime. A build-up of small circular water droplets starts to appear on the external bottom of upper container. Water droplets are allowed to fall freely in the lower container, pH of droplets water is about 7.1. Yield of freshwater is at a rate of approximately 300 ml freshwater from 400 ml wastewater per 48 hours.

Claims

The obtained freshwater collected in the lower plate. Another device is arranged to consist of three glass Petri dishes and fix one over the other to make upper, middle and lower plates. A volume of 60 ml wastewater, can be increased or decreased, is placed in each of the upper and middle plates and 60 ml of distilled water, can be increased or decreased, in the lower plate. The device is exposed to sunlight but not to direct sunrays, at room temperature. The obtained water droplets which is collected, in small beakers, from the lower surface of the upper and middle plates, wherein a volume of 60 ml wastewater, can be increased or decreased, is put in the upper plate and 20 ml distilled water, can be increased or decreased, in the lower plate.

DETAILED DESCRIPTION OF THE SEVERAL EMBODIMENTS

[0035] To make the present disclosure clear, the following embodiments give detailed description.

Embodiment 1

[0036] In a bench scale experiment, a device consists of two glass Petri dishes, fixed one over the second to make upper and lower plates. A volume of 60 ml of wastewater is put in the upper plate and 20 ml of distilled water in the lower plate. Place the device beside a window to be exposed to sunlight. On examination the lower surface of the upper plate after 30 minutes is cloudy and buildup of water droplets starts and is increased as time passes. Water droplets increase in size with time and allowed to fall freely on the lower plate and was measured by the increase of water volume of the lower plate. After 48 hours, water in the upper plate dried out leaving waste debris and the volume of water in lower plate increased by approximately 44 ml.

Embodiment 2

[0037] Further, in another bench scale experiment, arrange a device to consist of three glass Petri dishes and fix one over the other to make upper, middle and lower plates. Put 60 ml wastewater in each of the upper and middle plates and 20 ml of distilled water in the lower plate. Place the device beside a window to be exposed to sunlight. On examination the lower surface of the upper and middle plates after 30 minutes are cloudy and buildup of water droplets starts and is increased as time passes. Collect water droplets from the upper and middle plates with sterile glass rod to measure its volume. The water volume is approximately double the volume obtained in step 4.

Embodiment 3

[0038] In an outdoor experiment, use rounded plastic containers of same size and arrange as upper and lower plates. A volume of 400 ml wastewater is put in the upper plate and 100 ml of distilled water in the lower plate. Place the device outdoors to be exposed to direct sunlight and was inspected regularly. After 48 hours, wastewater in upper plate dried out leaving debris while in the lower container freshwater was about 400 ml at experiment termination.

Technical Description

[0039] In the present invention, we used SE in form of the entire electromagnetic spectrum that reach the earth surface as the sole source of energy. Making use of the fact that ordinary bulk water exists in two kinds: HDW and LDW prompted us to think of the present invention. For instance, in the upper container the positively-charged HDW lies in lower position and towards the container's upper side lies the negatively-charged LDW. The lower container contains distilled water with negatively-charged ions.

[0040] Hence, the negatively-charged distilled water ions in the lower container attracted the positively -charged HDW ions in the upper container through the bottom of the upper container that function as filter using the power of ‘unlike poles attract’. It provide fresh droplets water free of solute organic and inorganic matter in wastewater. Beside the power of “unlike poles attract” that induce emerging of circular water droplets through glass or plastic material in the bottom of the upper container, in the present invention, may be interpreted by the “quantum tunneling state” of the water. Discovery of this state of water contributes to the knowledge of utilization of energy by water. It has been reported that quantum tunneling allows particles to move through energy barriers and verified by using neutron scattering technology (Kolesnikov et al., 2016).
