Small Drinking Water Treatment Equipment

Water purification equipment and disinfection equipment for small drinking water, satisfying safe drinking water quality.

In order to ensure the safety of drinking water quality, we devised a device with a treatment process that can be operated automatically, and the purified water treated for hygiene safety of drinking water consists of an integrated device that can disinfect chlorine using sodium hypochlorite. Achieve small drinking water quality with less operator dependence on expertise and hygiene safety by chlorine disinfection.

It is an integrated water treatment device capable of water treatment and chlorine disinfection regardless of the water source such as river water, river abdominal water, valley water, ground water, etc. And, the device is characterized in that it is configured to ensure the hygiene safety of the water quality of drinking water without being greatly influenced by the professionalism of the device operator.

It is characterized in that the unit process such as micro-screen treatment, flocculation, sedimentation, filtration, disinfection, which are commonly used in the water treatment process is provided, and the raw water withdrawn is introduced into the collection tank (2) through the inlet pipe (1) In the catcher collection (2), a fine screen (3) was installed to remove the suspended matter introduced with the raw water, and the water passed through the fine screen (3) was introduced into the inclined plate settling basin (4). And, when the turbidity of the incoming raw water is high, the flocculant is injected into the raw water inlet pipe 1 to be in-line mixing, so that rapid mixing and instantaneous reaction required for the flocculation reaction occur quickly. The sedimentation process was made in the inclined plate sedimentation basin (4) with the inclined plate (5) to increase the sedimentation efficiency, and the sediment flowing out through the sediment overflow stream (6) was naturally flowed down the multi-layer filter paper (7). Inflow by water flow maximizes the operational efficiency of the filter paper and minimizes the turbidity of the filter water. The filtered purified water enters the purified water 9 through the filtered water outlet pipe 8. When the filtered purified water enters the purified water 9 through the discharge pipe 8, chlorine disinfects by injecting a safe sodium hypochlorite solution. It was designed to ensure hygienic safety by ensuring disinfection during the residence time in the purified water.

When the water head in the multi-layer filter paper 7 is continuously operated for a certain period of time, the water level in the filter paper is gradually increased, and when the water level is reached, the filter paper is configured to be automatically backwashed hydraulically by the operation of the water gauge. The wash tank (11) was placed on top of the purified water (9) so that the backwash water was hydraulically supplied to the lower part of the filter paper through the backwash water inlet pipe (12), and the backwash water washed with the filter paper was backwashed trap ( 15) is collected and discharged out of the system through the backwash water outflow pipe (13), the venturi type suction facility (17) to automatically discharge the sediment settled in the collection tank and the sedimentation basin by utilizing the outflow energy of the backwash water. The device is characterized in that the precipitate is discharged at the same time as the backwash water. This process is described in detail. When the backwash water is discharged through the backwash water outlet pipe, if it is injected through the nozzle of the venturi type suction device, a negative pressure is formed in the device to suck water from the sediment discharge pipes 14 and 14 'connected to the outside. At this time, the sediment is also sucked out and discharged.

Construction of inexpensive facilities in small-scale water supply facilities (about 12,000 nationwide), which make up a large part of local water supply, and ensuring hygiene and safety of drinking water quality.
