This modular water purification unit features automatic water intake, automatic timed sludge discharge, automatic backwashing, and can control the automation of its own equipment and the automatic interlock of other related equipment based on the liquid level of the clear water tank.
Utilizing grid coagulation pond reaction coagulation, with a box-like structure, it represents a key process at the beginning of the three conventional physical treatment methods in waterworks. Prior to the raw water entering the grid coagulation and sedimentation, it must pass through the tube-type mixer's dosing port, where coagulants (solution) are added. After the initial mixing, the water undergoes multi-layer grid coagulation, further slowing the flow rate. As the water flows through the grid holes, it contracts, expands after passing through the grid, and the flow rate decreases. This sustained segmented turbulence causes the floc particles to collide repeatedly, effectively squeezing out the water within the flocs. Under the action of the coagulant, a dense, easily separable floc is formed, which then settles.
The sedimentation area is equipped with honeycomb inclined tube packing (with a pore size of 35mm and a thickness of ≥δ0.6mm). To withstand the shock load caused by sudden water flow changes, the inclined tube packing is made of ethylene propylene copolymer (modified), which boasts long service life underwater, high strength, and excellent shock resistance. This raw material allows for a thorough reaction between raw water, suspended particles, and chemicals, enabling the flocculent in the water to come into full contact with impurities in the circulation state of the water distribution area, forming large flocculents. These formed large flocculents become denser and larger, with a flocculent density greater than water's density, sinking by gravity to the bottom sedimentation area. Smaller flocculents, with a density close to water, enter the inclined tube sedimentation area together. Due to the adsorption and adhesion of the flocculents on the inclined tube wall, the system equipment operates continuously, causing the flocculents on the inner wall of the inclined tube to accumulate over time. When the action of the water flow loosens the large flocculents formed on the inclined tube wall, they slide down under gravity into the sedimentation area. The sludge in the sedimentation area is automatically discharged into the external drainage channel by the排污阀 through the force of water gravity (static pressure).
The Rotary Lobe Blowers, pipelines, cables, control cables, as well as the power distribution cabinet and control cabinet for the filter bed backwashing are all automatically controlled by an integrated unit's PLC control box with an automatic program.

Key Technical Advantages of Modular Integrated Water Purification Equipment
◆ Designed for the source water quality, employing rational design parameters and purification technology, aiming for simplicity and reliability.
Intelligent Water Inflow System; intelligently controls and adjusts valve opening based on the feedback signal from the inflow flow meter, stabilizing the water inflow without human intervention, achieving intelligent and stable water production.
◆ Utilizes a grid-type static mixer; achieves instant mixing by the internal cross-mixing, which results in分流, cross-mixing, and reverse vortex effects, ensuring the added chemicals are quickly and evenly distributed throughout the water body, achieving instant mixing with excellent results and reducing user investment.
◆ Drum-shaped mesh flocculation device; enhances flocculation efficiency, shortens flocculation time, and reduces the amount of flocculant required. The flocculated mass formed by raw water and chemical solution undergoes multiple collisions in the reaction zone, resulting in larger floccule particle sizes and denser flocs.
Net water treatment sedimentation zone; utilizes a balanced overflow water distribution area, ensuring stable water flow speed, maintaining uniform distribution, and no cross-flow phenomena.
◆ Integrated water purifiers utilize slanted tube media; made from stainless steel 304 with automatic welding, the internal slanted holes are smooth with consistent sizes and no deformation, ensuring even water surface load increase in the sedimentation zone, reducing water turbulence, and eliminating dead-end crossflow, enhancing sedimentation efficiency. It boasts long service life, high strength, and excellent resistance to impact forces.
◆ Sludge collection and drainage area; utilizing U-shaped sludge collection channels, each water purification unit is equipped with multiple collection channels. Combined with our company's siphon expansion drainage device, it features increased sludge concentration, thorough and clean drainage, uniformity in drainage, no dead corners, and short drainage time without wasting water resources.
◆ The filter pond utilizes a traditional gravity-based filter pond; the filter media layer is designed as a two-layer structure, with a filtration rate designed to be within 5-7 m/h. It boasts advantages such as a large amount of suspended solids removal, a deep collection and infiltration layer, a long filtration cycle, and stable effluent water quality.
◆ Smart Control Water Module; the intelligent water regulating valve adjusts the valve opening based on the water level signals from the clear water pool and filter tank, maintaining the water level of the filter zone at the preset constant level.
Intelligent anti-money laundering module; filters based on the clogging status of the filter bed. When the surface of the filter layer is clogged with pollutants, the filter layer can no longer hold water, and the water level rises to the preset backwashing water level, at which point the water level pressure controller is activated to automatically start the backwashing unit.
