2: Clarification mechanism of coagulant
Chemical coagulation is a process in which chemical agents (coagulants) are added to water treatment to make colloidal dispersion system destabilize and agglomerate. In the coagulation process, small suspended particles and colloidal impurities are aggregated into larger solid particles to separate particulate impurities from water, which is called coagulation clarification.
After adding coagulant into water, colloidal particles and other small particles can be polymerized into larger flocs through the comprehensive action of mixing, coagulation and flocculation. The whole process of coagulation and flocculation is called coagulation.
(1) Destabilization and condensation of colloids
Adding electrolyte to water can compress the electric double layer and destabilize the colloid. The main mechanism is that the electric double layer of colloidal particles in water is compressed or neutralized by adding aluminum salt or iron salt coagulant. The coagulant and raw water are mixed rapidly and evenly, and a series of chemical reactions are produced to destabilize. This process takes a short time, generally about 1 min. Some cationic polymers can also play a role in the destabilization and condensation of colloids in water. These polymers have a long chain structure and positive charge in water. Their destabilization and condensation of colloids in water is due to the interaction of van der Waals force adsorption and electrostatic attraction.
(2) Flocculation and formation of floc (alum)
The particle size of the initial flocculate formed by colloid destabilization and coagulation in water is generally more than 1 m. at this time, Brownian motion can no longer push them to collide and form larger particles. In order to make the initial flocs collide with each other to form large flocs, it is necessary to input additional energy into the water to produce a velocity gradient. Sometimes it is necessary to add organic polymer flocculant into water, and the adsorption bridging effect of long chain molecules of flocculant is used to improve the probability of collision and adhesion. Flocculation efficiency usually increases with the increase of flocculate concentration and flocculation time.
Compared with polyaluminum chloride, polyaluminum chloride has the advantages of high density, fast settling speed and wide pH adaptability; the coagulation effect is less affected by temperature than that of polyaluminum sulfate; however, when adding ferric salt, it should be noted that when the equipment is not in normal operation, the iron ions will make the effluent color, and may pollute the subsequent desalination equipment.

It's also worth noting that even prior to the EU decision, France had already outlawed titanium dioxide in food back in January 2020.
Benefits of Using a Main T Ceiling Grid
The installation of a mineral fibre suspended ceiling involves several steps. First, a grid system is attached to the existing ceiling or framework, which serves as a support structure for the tiles. This grid can be adjusted to accommodate different heights, ensuring a level and aesthetically pleasing final product. Next, the mineral fibre tiles are simply dropped into the grid. This drop-in method allows for flexibility, as tiles can be replaced or repositioned with ease.
Step 7 Test the Access Panel
One of the primary advantages of ceiling mineral fiber is its excellent sound absorption properties. In spaces where noise reduction is paramount—such as classrooms, offices, and auditoriums—these tiles can significantly improve acoustic comfort. The porous structure of mineral fiber allows sound waves to penetrate the material, thereby reducing reverberation and echoes. This feature makes it an effective solution for creating quieter, more productive environments.
Installing a ceiling access panel can be a valuable addition to your home or commercial space, providing easy access to plumbing, electrical wiring, or ductwork hidden behind drywall. A properly installed access panel not only enhances functionality but also maintains a clean and professional appearance. This article will guide you through the installation process of a ceiling access panel, ensuring you can tackle the project with confidence.
