Fundales play an important role in water treatment and sewage treatment. They promote the gathering and precipitation of suspension through different mechanisms, thereby achieving a clear and transparent water body or reducing solid particles in sewage. The following are some of the main functions in the field of water treatment and sewage treatment: Combination: The…
Surface active agents are compounds that can reduce surface or interface tension on different phase interfaces. According to its molecular structure and ion properties, the surfactant can be divided into the following categories, and the representative substances of each category can be listed: Cattea surface active agent: Sixteen alkyl tritenomonium bromide (CTAB): Commonly used for…

The chelating agent refers to a compound that can form a stable chelated matched mathematical with metal ions. They can formatting with metal ions to form a stable complex. Chelators are widely used in many fields, including medicine, environmental protection, and industry. The following is the role of chelating agent and some potential hazards: effect:…
Water reduction is a chemical additive that is commonly used in concrete and cement products. It can effectively change the liquidity of concrete and reduce the water -asx ratio, thereby improving the working performance and strength of the concrete. The water reducing agent is usually composed of the following main components, and each component has…

Bybaches is a type of chemicals used to kill or inhibit bacteria, fungi and other microorganisms. They can be used in agriculture, medical care, disinfection, environmental hygiene and other fields. According to the specific chemical components and concentrations used, the bactericide may have some harm to the human body and the environment. Some common bactericides…
The flocculant is a chemical that can gather solid particles that can float in liquid into larger and heavier blocks to sink or filter separation. The main components of the flocculant can be selected according to different applications and goals. The following are some common flocculant components: Inorganic salts: such as aluminum salt and iron…

Non -ion surface active agents are a type of chemical, and they have no ionization groups in the molecular structure. Non -ion surface active agents have the characteristics of reducing liquid surface tension, increasing solution viscosity, improving emulsification and decentralized performance. These substances are usually composed of carbon chains and hydrophilic groups, which can provide…
For the formula of a bactericide, the specific component and ratio will depend on factors such as the target microorganisms, application areas, and regulatory requirements that they want to kill. Here are some common ingredients that may be used in some common sterilizers formula: Alcohol: such as ethanol (alcohol) and propyallol. Alcohol has a strong…
Sandwashing special flocculant is a flocculant for the selection of gravel. It is mainly used to handle the suspended solid particles in the scrubbing wastewater, and quickly condense and precipitate it, thereby achieving the separation and recycling of water from solid. The formula of special flocculants for sand washing is usually different according to specific…
Chelature is a common laundry liquid additive, which plays the following role during laundry: Remove stains: The chelated agent can form a complex with the metal ions (such as iron, manganese, etc.) in the water to prevent these metal ions from reacting with stain substances, thereby reducing the adhesion and precipitation of stains, and improving…
