The amount of polyacrylamide (PAM) required to treat sewage depends on various factors, including the nature of the sewage the desired treatment objectives, and the specific treatment processes involved. Polyacrylamide is commonly used as a flocculant in sewage treatment plants to aid in the precipitation and removal of suspended solids.

To determine the appropriate dosage of PAM, several parameters need to be considered, such as the characteristics of the sewage (e.g., suspended solids concentration, organic content), the desired level of treatment (e.g., solids removal efficiency), and the effectiveness of the PAM product being used.

Typically, the dosage of PAM is expressed in parts per million (ppm) or milligrams per liter (mg/L) of sewage. Dosage recommendations can vary widely depending on the specific application, but a common range for PAM dosage in sewage treatment is between 1 and 10 ppm.

It's important to note that the dosage requirements may differ for different treatment stages within a sewage treatment plant, such as primary sedimentation, secondary biological treatment, or tertiary filtration. Additionally, the dosage may be adjusted based on the actual performance and results obtained during the treatment process.

To obtain accurate and reliable dosage recommendations for your specific sewage treatment scenario, it is advisable to consult with a qualified wastewater treatment professional or refer to the manufacturer's guidelines for the specific PAM product being used.

Non-leafing
With non-leafing aluminium pastes, as shown below, the flake-shaped microparticles distribute uniformly into parallel layers throughout the paint or coating layer. As a result, the colour effect of pigments or other colouring materials present in the paint or coating remains fully visible from the outside.

Design grades
Design-grade aluminium paste, in grades ranging from Basic Design Grades to the MH, BS, and GX Design Grade Series, is a product of advanced process technology by Tuocai that enables the creation of previously unattainable levels of surface appearance and visual effects.

As shown in the micrographs below and the Design Grades map, this technology provides closer control and higher uniformity of the microparticle size, together with higher surface smoothness. The result is higher brightness with smaller particle size – which overturns the longstanding conventional wisdom that brightness must vary in proportion to particle size.

Resin coated grades

Resin coated aluminium paste from globaltuocai provides heightened resistance to acids, alkalis, weathering, voltage, and other demanding environments, and increased bond strength within the paint or coating layer.

The broad-based technology and expertise of Tuocai in resin types and processes permit a comprehensive selection of coating types and thicknesses, to provide maximum performance for specific application requirements and conditions.

Leafing
With leafing-type aluminium pastes, the aluminium microparticles tend to float in the paint or other coating during its application to the substrate, and thus form an array of parallel particle layers at or near the surface of the coated layer, as shown below.

This facilitates the achievement of a silver- or chrome-like visual effect, but care is necessary in its application and use it may also obscure the visual effects of the pigment or other components of the paint or coating layer.

Tuocai provides a range of leafing-type aluminium paste types and grades, and related expertise in their use and performance characteristics.

Fruit and vegetable juices such as pears, apples, bananas, and potatoes can easily become discolored. Not only is discoloration unsightly, but the flavor is also affected. What to do? You can add some lemon juice. In the food industry, people can just add ascorbic acid based on the mechanism of action of lemon juice. Many of the juices and vegetable juices sold in supermarkets have ascorbic acid added to the wine to maintain its appearance and flavor. 

 Fruits and vegetables contain more or less polyphenolic compounds. After peeling, these compounds are exposed to air to be oxidized, producing quinone (kūn) compounds. These quinone compounds are easily linked to each other and become "brown pigments" that discolor these foods. Lemon juice contains a large amount of "ascorbic acid", which can restore the quinone to its original polyphenol state; it can also be oxidized directly, thus consuming the oxygen around the polyphenols, and thus protecting the polyphenols from the attack of oxygen. In this way, ascorbic acid sacrifices itself to protect the fragile polyphenols, to maintain the "fresh" color of fruits and vegetables. 

The role of  Ascorbic Acid is not limited to this. People often add nitrite in cooked meat products. Nitrite has two functions: one is to react with myoglobin, making it appear attractive red; the second is to inhibit the growth of bacteria, to achieve the function of preservation. The addition of ascorbic acid can promote the former reaction, thus speeding up the process of "color". Many people believe that nitrite is a "carcinogen". In fact, it is not carcinogenic, only when it reacts with the amino acids in the meat to produce nitrosamines is a carcinogen. If ascorbic acid is added to meat, it will inhibit this transformation process, thus reducing the "possible" cancer risk of nitrite. Ascorbic acid is also sometimes added to meat products that do not require nitrites. This is because the oxidation of fats and oils in meat releases a bad taste, often referred to as "harry". If ascorbic acid is added, it will consume the surrounding oxygen before it does, thus protecting the fats from oxidation and helping to keep the meat tasting "fresh".

Tetramethyl ammonium chloride, TMAC, easily soluble in water and alcohols, belongs to Quaternary ammonium compounds. It has a lot of applications in many fields, the following mainly introduces one of the most important functions of Tetramethyl ammonium chloride in oilfield exploitation.

Tetramethylammonium chloride is widely used as a shale inhibitor in oilfield exploitation. The clay content in shale is high. When water-based drilling fluid comes into contact with shale, it can cause clay to expand and disperse, leading to wellbore collapse. Shale swelling and dispersion when encountering water are caused by the dissociation and hydration of exchangeable cations on the surface of shale in water, forming a diffusion double layer with negative charge and generating electrostatic repulsion. Therefore, drilling fluid should have two major functions-preventing or delaying water migration from the wellbore to the wellbore, and increasing the connectivity between mineral particles on the wellbore. Cationic surfactants can produce surface active cations after dissociation in water, which can adsorb on the clay surface, neutralize the negative charge on the clay surface, and inhibit shale expansion and dispersion, thereby stabilizing the wellbore.

Ahsuperchem is the stable supplier of Tetramethylammonium chloride, we supply TMAC with the purity of 50% liquid and 99% powder, if you have any interests in this material, please contact us freely.

👉 Global Polyacrylamide Market: Overview
Polyacrylamide is a polymer that is created by the synthesis of acrylamide subunits and is widely utilized in the water treatment and papermaking industries. The need for wastewater management and growing environmental concerns have raised polyacrylamide demand. In water management, flocculants and coagulants—organic polymers—help separate suspended solid or liquid particles. Here, coagulant polyacrylamide is used to improve the coagulation-flocculation process. In the pad drilling method that is typically used to produce shale gas, polyacrylamide reduces friction.


👉 Global Polyacrylamide Market: Growth Factors
The mining industry uses polyacrylamide extensively to separate minerals and ores in the mines, which is anticipated to fuel the expansion of the polyacrylamide market. The bio-based acrylamide is being commercialized by few polyacrylamide manufacturers, which presents a huge growth opportunity for the global market. Anionic polyacrylamide is used by certain farmers and builders as a means of halting soil erosion by retaining suspended sediments. In order to increase the market for polyacrylamide, anionic polyacrylamide is also utilized in the processes of sugar juice clarification, water recycling, fermentation byproduct recovery, and water clarifying. But excessive polyacrylamide use is bad for human health, which is why the government and numerous environmental organizations have put limits on polyacrylamide use.
