The Gatekeepers of the Pre-treatment Phase
The first step in water treatment is akin to giving the water a physical check-up; these devices are responsible for intercepting obvious impurities:
Screening Machines: Acting like a comb, they rake out large debris from the water, such as branches and plastic bags.
Grit Chambers: Utilizing gravity, they allow sand and grit to settle naturally, thereby protecting downstream equipment from abrasion.
Equalization Tanks: Serving as flow buffers, they balance fluctuations in water volume occurring at different times.
Multi-media Filters: Comprising a multi-layered filter bed of quartz sand and activated carbon, they are capable of capturing 80% of suspended solids.
The Core Purification Forces
The actual transformation of water quality takes place within these devices:
Ultrafiltration Systems: Featuring hollow fiber membranes with a pore size of 0.01 microns, they effectively block bacteria and colloids.
Reverse Osmosis Units: Employing high pressure to force water molecules through a semi-permeable membrane, they achieve a desalination rate of up to 95%.
Disinfection Equipment: UV sterilizers offer chemical-free disinfection, while ozone generators are ideal for treating difficult-to-degrade organic substances.
Water Softeners: Resin exchange tanks are specifically designed to combat limescale by exchanging calcium and magnesium ions for sodium ions.
Intelligent Auxiliary Systems
The "brains" behind modern water treatment:
Online Monitors: Continuously track over 10 key parameters-such as pH and turbidity-24 hours a day.
Automatic Dosing Units: Precisely dispense flocculants in response to real-time changes in water quality.
Sludge Dewatering Machines: Compress sludge with a water content of 99% into "sludge cakes" with a water content of 60%.
Reclaimed Water Reuse Systems: Recycle treated water for secondary uses-such as landscaping or flushing-achieving water savings of 30%.
