Anonymous users2024-02-10The purpose of testing the moisture in the sludgeSludge is the product of separation in urban sewage treatment, and the treatment method of urban sludge is generally the method of underground landfill. In the GJ3025-1993 sewage sludge discharge standard for municipal sewage treatment plants, it is clearly stipulated that the sludge of the urban sewage treatment plant after stable treatment in the plant should be dewatered, and its moisture content should be less than 80%. So what is the moisture content of untreated sludge?
Today we will test the customer's sludge sample with a rapid moisture meter to detect how much moisture content of the untreated sludge is.
Advantages of Guanya sludge moisture detector1. Based on the principle of loss on drying method, the moisture measurement system is independently developed to maintain good consistency with the moisture value of the drying method.
2. The instrument has a precise structure, strong and durable, small size and exquisite appearance.
3. Imported load cell solves weighing problems such as temperature drift and time drift and improves measurement accuracy.
4. The temperature control system adopts imported high-sensitivity temperature control components to ensure the temperature and controllability during the test.
5. The halogen heating method is used to make the sample more evenly heated and drier.
6. Specific heating wavelength, stronger penetration ability, so that the product is heated faster and the measurement is faster.
7. One-button operation, no training required, laboratory or production staff can operate independently.
8. Fully automatic measurement, the instrument determines by itself to avoid human error.
9. Zero consumables in the use process, stainless steel sample tray, reusable, energy-saving and environmentally friendly.
10. Perfect after-sales service system to solve customer feedback problems in a timely and rapid manner.

Anonymous users2024-02-09The cost of sludge treatment is very high, and now the country advocates the concept of sludge reuse, so all places use technical means to process sludge, and the sludge form under different conditions of moisture content:
When the moisture content is more than 85%, the sludge is in a flowing state;
65% to 85% plastic;
If it is less than 60%, it will be solid, and the Ministry of Environmental Protection requires the sludge in the sewage treatment plant to reach a moisture content of less than 80% after treatment, and if it is landfilled, the moisture content cannot exceed 50%. The quality inspection department also put forward the sludge dewatering standard, with a moisture content of 40% and a solid content of 60% after treatment. From a policy perspective, the lower the moisture content of sludge treated by sludge treatment enterprises, the easier it is to meet the relevant environmental protection requirements of various departments.
CS-002 sludge moisture content tester not only has the advantages of simple operation, fast test speed and high efficiency, but also has small error in test results. It can meet the quality needs of environmental protection users for moisture. The traditional test process takes 4 hours to produce results to determine the sludge production process and dewatering quality, which can not guide and produce in a timely and effective manner for the industrial production of enterprises, which hinders the development of environmental protection enterprises.
After using the CS-002 sludge moisture content moisture analyzer, the production and experimental departments can check whether the moisture of each batch is qualified at any time, which greatly improves the production efficiency. At the same time, the data can be printed out after the test is completed, and the data can also be effectively analyzed in real time by connecting the upper analysis software through the computer.

Anonymous users2024-02-08Interstitial water refers to the water surrounded by large and small sludge particles, accounting for about 70% of the water in the sludge, it is not directly bound to the sludge, so it is easy to separate from the sludge, and this water can be significantly reduced by gravity concentration. X0D Capillary bound water refers to the water combined by capillary pressure on the contact surface of solid particles, or filled with water in the cracks of the solid particles themselves, accounting for about 20% of the water in the sludge, and the removal of such water needs to apply a force in the opposite direction to the surface tension of the capillary water, such as the centrifugal force of a centrifuge. X0D surface adhesion water refers to the water that adheres to the surface of small particles of sludge, which is more difficult to separate than capillary bound water and needs to be separated by electrolyte as a coagulant.
X0d internal water refers to the water inside the microbial cell, and the removal of internal water must destroy the cell structure, so it is difficult to use mechanical methods, and it can be converted into external water by means of heating or freezing, or it can be removed by microbial decomposition methods such as aerobic oxidation and anaerobic digestion.

Anonymous users2024-02-07Sludge is a solid sediment produced by water and wastewater treatment processes.
Sludge moisture content.
The percentage of the weight of the water contained in the sludge to the total weight of the sludge is called the sludge moisture content.
The forms of water in sludge are: void water, capillary water, surface adsorption water and internal bound water.
Pore water, free water in the intergranular interstitials, about 70%, can be separated by gravity precipitation (concentration and compaction);
Surface adsorption water, about 5%, is the water attached to the surface of sludge particles, its adhesion is strong, often appears on solid surfaces such as colloidal particles, biological sludge, etc., using coagulation method, through colloidal particles flocculating with each other, excluding the moisture on the attached surface, can be removed by biological separation or thermal methods.
Internally bound water, about 5%, is the moisture bound inside the sludge particles, such as the internal moisture of cells in biological sludge, the crystalline water carried by metal compounds in inorganic sludge, etc., which can be removed by biological separation or thermal methods.
Usually, when the moisture content is more than 85%, the sludge is in a flowing state; 65% to 85% plastic; Below 60%, it is solid.
Equation v1 v2 = (100-p2) (100-p1).

Anonymous users2024-02-06Moisture content and solid content.
The moisture content is the percentage of the water content in the sludge; The solids content is the percentage of solid or dry sludge content in the sludge; The product of the amount of wet sludge and the solid content is the amount of sludge; A decrease in moisture content (i.e., an increase in solids) will greatly reduce the amount of wet sludge (i.e., sludge volume); When the moisture content changes, the volume of wet sludge can be approximated;
Usually: the moisture content is > 85%, and the sludge is in a fluid state;
65 85%, the sludge is plastic;
65%, semi-solid.
Investment multiplier k = 1 (1-marginal propensity to spend). Based on c = 100 + marginal propensity to consume so the investment multiplier is 1 ( = 5.).

Software requirements analysis is particularly important. For a long time in the history of software engineering, requirements analysis was considered a simple step in the overall software engineering process, but over the past decade or so, more and more people have recognized it as the most critical process in the whole process. It is only through software requirements analysis that the general concept of software functionality and performance can be described as specific software requirements specifications, thus laying the foundation for software development. >>>More
Proactive, active, whole-of-society defensive behavior. The cultivation of long-term, active, active, and whole-society defense behaviors before the occurrence of the first event depends on the formation and improvement of the public's awareness of disaster prevention and reduction, which requires a large number of in-depth, long-lasting, and extensive publicity on disaster prevention and mitigation and popularization of disaster prevention and mitigation knowledge. We say that it is better to avoid disasters for a thousand days than to prevent disasters for a day, and this is what we mean. >>>More
