River Water Treatment | Water Filtration Systems

I. Background of river water treatment equipment

 The water quality of river water is affected by multiple factors such as weather, upstream sewage, soil condition and upstream engineering projects, showing instability. Especially under extreme weather conditions such as heavy rain, the content of sediment and other impurities in the river water increases dramatically, resulting in turbid water quality and high suspended solids, which brings great challenges to water treatment.

Ⅱ. The working principle and process of river water treatment

1. Reaction chamber:

 ● Construction: carefully constructed by small wave plate to form an infinite reaction space.

 ● Advantage: Using wave crest and trough design to ensure that the floc is not easily destroyed during the reaction process, realizing full reaction, improving flocculation efficiency and significantly reducing the amount of coagulant used.

2.Sedimentation chamber:

 ● Construction: Utilizes large wave plate design to implement shallow sedimentation method.

 ● Principle: The water flows in the reverse direction, and the wave crest and trough design makes the water flow upward and the mud slide downward, realizing automatic and rapid separation.

 ● Effect: The turbidity of the effluent from the sedimentation area is stably lower than 5NTU, which creates good conditions for the subsequent filtration process, reduces the load of the filter tank, and prolongs the backwashing cycle.

 ● Characteristics: The lower part of the sedimentation combination is equipped with a mud collection hopper, which ensures that the mud directly enters and self-sinks, reduces the water content of the mud discharge, and prolongs the

3. Mud discharge cycle:

 ● Filtration chamber:

 ● Construction: adopts double-layer filtering media, split-format pressure filtration design.

 ● Advantage: When backwashing, one filter chamber can be operated separately, and other filter chambers keep normal operation to ensure water supply continuity.

Ⅲ. The scope of application of river water treatment equipment

 1. Applicable to all kinds of rivers, streams, lakes, reservoirs and other water sources where the turbidity of water is less than 3000mg/L. It is widely used in the water plants of rural areas, towns and industrial and mining enterprises as the main water purification and treatment device.

 2. It has special adaptability to low temperature, low turbidity, and lake water source with seasonal algae.

 3. Applicable to all kinds of industrial circulating water system, effectively improve the quality of circulating water.

 4. Suitable for water reuse system, with sewage plant effluent as water source, water purification and reuse treatment.

Ⅳ. The river water treatment equipment features

1. Highly automated:

 Water purification device from the reaction to a series of operating procedures such as sewage discharge are realized automatically, on-duty personnel only need to regularly monitor the water quality measurement, no need for frequent operation and management.

2. High-efficiency flocculation:

 High concentration of flocculation layer to ensure that the impurity particles in the raw water to get full contact with the collision, improve the chance of adsorption, adapt to a variety of raw water temperature and turbidity, high removal rate of impurity particles.

3. Swift sludge discharge:

 Sludge thickening chamber is designed to be swift, and the adjustable automatic sludge discharge system ensures that the excess sludge and impurities are removed in time, maintaining a stable removal rate of impurity particles.

4. High-quality precipitation water:

 Efficient flocculation and precipitation effect makes the water quality of precipitation water maintain a good state, providing a strong guarantee for the subsequent filtration process.

5. Energy saving and consumption reduction:

 High degree of automation of the water purification system, not only to ensure efficient water purification (turbidity of raw water is less than 3000mg / L, the turbidity of the filtered water can be maintained at 3mg / L or less), but also automatic backwashing, without the need to set up additional backwashing pumps or air compressors and other electrical equipment, saving a lot of infrastructure investment and daily operation, repair and maintenance costs.

6. Low self-consumption rate:

self-consumption rate is about 5% or less, which has a positive effect on saving limited water resources.

7. Small footprint:

Compared with general water purification structures, it can save more than 50% of the footprint, with a height of about 4.10 meters, and can be flexibly placed indoors and outdoors.
