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.
Health advocates urge US regulators to ban common food coloring additive, by Tom Perkins, The Guardian, June 2, 2023
Titanium dioxide is a versatile material with a wide range of applications. Some of its most common uses include:
1. Pigment and Food Coloring
Titanium dioxide is one of the most widely used white pigments, often used to add whiteness and brightness to products. It is used in the production of paints, coatings, plastics and other products to provide a white color or opacity.
It’s also used in food products to provide a white color. Candies, cakes and creamers are examples of foods that may contain titanium dioxide for its color enhancing and bleaching properties.
2. Cosmetics
Titanium dioxide is often used as a UV absorber and pigment in cosmetic products, such as foundations, lipsticks, creams, sunscreens and other skin care products. It helps protect the skin from the harmful effects of UV rays by blocking them, while providing a brightening effect.
However, it can cause photosensitivity, which

Moreover, fencing plays a significant role in crop protection. Farmers invest considerable resources into cultivating healthy, high-yield crops, and safeguarding these investments is paramount. Fences serve as physical barriers against wildlife that might otherwise munch on crops, including deer, rabbits, and various birds. In addition to preventing damage from animals, fencing can also help contain farm inputs, such as fertilizers and pesticides, within designated areas, which is crucial for environmental management and compliance with agricultural regulations.
When installing razor barbed wire fencing, several factors must be taken into account. First, the height and thickness of the fencing are crucial for maximizing security. A standard recommendation is to install the wire at least six feet above ground, combined with solid fencing or walls for the best effect.
One of the primary reasons pet owners choose wire mesh dog cages is the safety they provide.

The rabbit border fence was no ordinary fence. Crafted from intricately carved wood, it rose to a modest height, just enough to keep curious critters at bay while inviting the neighborhood children to peer in. The wood was adorned with charmingly detailed carvings of rabbits, each one unique in its expression. Some rabbits appeared to be laughing, while others looked thoughtful, and a few seemed to be frolicking in playful mischief. The fence, with its lovely designs, told tales of the rabbits that resided within the garden, their adventures woven into every groove and notch.
Additionally, in landscaping and outdoor structures such as pergolas, gazebos, and signs, post anchor spikes help to secure these elements against wind uplift and shifting soil conditions. This stability is vital not only for the aesthetics of a project but also for its functional safety. The choice of material for these spikes—whether steel, aluminum, or other composites—can significantly affect their performance under different environmental conditions.
