Description

Independent energy and water supply management system {STAND-ALONE ENERGY AND WATER SUPPLY MANAGEMENT SYSTEM}

The present invention relates to a self-contained energy and purified water supply management system, and more particularly, by combining an energy storage system using renewable energy as a supply source and a power storage water treatment method, it is possible to recover the stored energy again after water purification, so that energy efficiency and It relates to a self-contained energy and purified water supply management system that can reduce energy consumption.

In areas where a tap water is not installed or where a large amount of water is required, even if a tap water is installed, the purified water is often used as drinking water by drawing water (hereinafter referred to as "raw water") flowing from underground water, valleys and rivers. Are doing.

However, such raw water has high turbidity due to the large number of floating matters, especially in the case of industrial sites or underdeveloped areas, due to the indiscriminate wastewater discharge and lack of water treatment facilities, it contains a lot of various heavy metals and odorous organic substances. It is classified as a contaminated area.

In this way, in order to use raw water with severe contamination as a clean and safe drinking water, it is necessary to have facilities such as a large water purification plant that purifies through dozens of steps.

However, the facilities for equipping such a large-sized water purification plant are very expensive, so it is not possible to prepare large-scale, expensive water purification facilities, and most of them use water purified through a small water purification system as it is. Because it is in a state, safety is considerably poor.

On the other hand, conventional water purifier systems that purify raw water such as groundwater have a structure to purify using various types of filters such as a sediment filter or a reverse osmosis filter that filters and filters sediment.

1 is a block diagram showing a water purifier equipped with a plurality of water filters according to the prior art.

Here, the filter filtration water purifier according to the prior art is a sediment filter (1), a pre-carbon filter (2), an ultrafiltration (UF) (or microfiltration) filter (or reverse osmosis filter) ( 3), the water passes in the order of the post-carbon filter 4 and filtration is performed, and in general, a water flow may be formed by its own water pressure.

In addition, although not shown in the drawings, in the reverse osmosis water purifier according to the prior art, water passes in the order of a sediment filter, a pre-carbon filter, a pressure pump, a reverse osmosis filter, and a post carbon filter, and filtration is performed, and artificial pressure is applied to reverse osmosis. It can be purified by passing through an osmotic filter.

However, the pretreatment filter, which is mainly used as a pretreatment filter, is often clogged at an early stage, making it difficult to manage and cannot guarantee a large amount of purified water.Therefore, it is necessary to additionally use several filters where a large amount of water is required. There is a problem that falls a lot.

In particular, in the case of a reverse osmosis water purifier with excellent water purification effect, there is a problem that water resources are depleted because a large amount of raw water (60% ~ 70%) has to be discarded, and the filter replacement cycle is shortened to treat a large amount of raw water. There is a problem that a lot of maintenance costs are required.

Therefore, there is an urgent need for a practical and applicable technology that can reduce maintenance costs by increasing the water purification effect and extending the service life of the filter in the water purification system.
