Description

FIELD OF THE INVENTION

The present invention relates to an effluent liquid evaporator. More particularly, the present invention relates to an effective and sustainable evaporator to treat wastewater by increasing the evaporation rate with easy and automatic cleaning in an economical manner.

BACKGROUND OF THE INVENTION

Effluent liquid refers to any waste liquid or discharge that produces byproduct of industrial, agricultural, or domestic activities, other than the kitchen or toilet wastes. It particularly contains one or more contaminants including fats, chemicals, detergents, heavy metal rinses, solids and food waste that comes from various sources such as manufacturing processes, wastewater treatment plants, agricultural operations and sewage systems. Therefore, there is a requirement of treating wastewater before being released into the environment.

Wastewater treatment refers to the process of removing impurities from wastewater before the wastewater is delivered back into the environment to reduce the potential harm affecting the human health and the environment and to reuse or recycle the wastewater for various purposes.

Treating wastewater possess various challenges that needs to be addressed to ensure effective and sustainable wastewater management that involves technological advancements, policy reforms, public engagement, financial support and to prioritize investments in upgrading and expanding wastewater treatment infrastructure.

The conventional approach of the effluent liquid treatment, which includes various stages of filtration comprising primary treatment, secondary treatment and tertiary treatment. Primary treatment involves removal of solids, oil and grease, removal of floating & settable such as suspended solids, organic matter, and secondary treatment involves removal of biodegradable organic matter (BOD), and tertiary treatment involves removal of residual suspended solids and dissolved solids. However, the method is complex and requires high power to implement. This is followed by a water recycle process such as Reverse Osmosis and finally evaporation of the brine concentrate.

US20190330082A1 discloses a system and method for separating surface materials from a fluid, such as foam, sludge, oil or grease, at a fluid's surface, by applying acoustic pressure shock waves to the material and the fluid's surface such that acoustic pressure shock waves are propagated in liquid medium of the fluid and in gas medium above the fluid surface. However, this invention fails to provide an easy and automatic solution that consumes less power.

U.S. Pat. No. 8,147,700B2 discloses a wastewater treatment system and method comprises a treatment chamber having a filtration membrane spanning an effluent outlet of the chamber and a pair of electrodes in the treatment chamber so as to be in communication with the wastewater. An electrical potential difference is applied between the electrodes such that one of the electrodes functions as an anode and one of the electrodes functions as a cathode. A flow of fluid is induced out of the treatment chamber through the filtration membrane to the effluent outlet. Accordingly, the treatment chamber is arranged to biologically treat the wastewater, electrochemically treat the wastewater and mechanically filter the wastewater through the filtration membrane commonly therein. However, the maintaining and cleaning of this system is more challenging due to limited access to the treatment chamber and associated components.

KR101590408B1 discloses a small-scale wastewater treatment system which comprises a first settling tank, an electrolysis tank, a second settling tank, a gravity-type two-stage sand filtering apparatus, a pulsed ultra violet treatment tank, a ball mill crushing apparatus, and a sludge drying system. The treatment system of the present invention eliminates nitrogen and phosphorus, and allows sludge to be eluted from the settling tank after insertion of an acetic acid compound as a coagulant. In addition, a dried sludge cake is produced after drying the sludge in the sludge drying system, and treated water is discharged after final sterilization by pulsed ultra violet treatment tank. However, this invention fails to provide an easy and automatic solution that consumes less power.

Therefore, due to the above aforementioned drawbacks, there is a need of a system for treating effluent liquid that is economic, easy to operate, easy to clean and consumes less power.
