  2. Clarifying agent - Wikipedia

    en.wikipedia.org/wiki/Clarifying_agent

    Particles finer than 0.1 μm (10 −7 m) in water remain continuously in motion due to electrostatic charge (often negative) which causes them to repel each other. [citation needed] Once their electrostatic charge is neutralized by the use of a coagulant chemical, the finer particles start to collide and agglomerate (collect together) under the influence of Van der Waals forces.

  3. Flocculation - Wikipedia

    en.wikipedia.org/wiki/Flocculation

    A variety of salts may be added to adjust the pH and act as clarifying agents, depending on the water chemistry. These include sodium hydroxide , calcium hydroxide , aluminum sulfate , aluminum oxide , ferric sulfate , ferric chloride , sodium aluminate , with flocculant aids polyaluminum chloride , polyferric chloride .

  4. Clarification and stabilization of wine - Wikipedia

    en.wikipedia.org/wiki/Clarification_and...

    Many substances have historically been used as fining agents, including dried blood powder. [5] There are two general types of fining agents — organic compounds and solid/mineral materials. [4] Organic compounds used as fining agents are generally animal based, a possible cause of concern to vegans. [6]

  5. Finings - Wikipedia

    en.wikipedia.org/wiki/Finings

    Finings’ actions may be broadly categorized as either electrostatic, adsorbent, ionic, or enzymatic.. The electrostatic types comprise the vast majority; including all but activated carbon, fining yeast, PVPP, copper sulfate, pectinase and pectolase.

  6. Coagulation (water treatment) - Wikipedia

    For example, the Microscale Flocculation Test developed by LaRue et al. reduces the scale of conventional jar tests down to the size of a standard multi-well microplate, which yields benefits stemming from the reduced sample volume and increased parallelization; this technique is also amenable to quantitative dewatering metrics, such as ...

    They are thus often used as thickeners, emulsifiers, conditioners, clarifying agents, and even drag reducers. They are used in water treatment and for oil recovery. Many soaps, shampoos, and cosmetics incorporate polyelectrolytes. Furthermore, they are added to many foods and to concrete mixtures (superplasticizer).

  9. Tissue clearing - Wikipedia

    en.wikipedia.org/wiki/Tissue_clearing

    Many tissue clearing methods exist, each with different strengths and weaknesses. [ 2 ] [ 4 ] Some are generally applicable, while others are designed for specific applications. [ 4 ] Tissue clearing is usually useful only combined with one or more fluorescent labeling techniques such as immunolabeling and subsequently imaged, most often by ...
