How to Reduce Scaling of MBBR Media in Dairy Wastewater?

图片
  Introduction We often use MBBR media   in dairy wastewater to reduce the levels of BOD (Biochemical Oxygen Demand) and COD (Chemical Oxygen Demand) in the water. However, during the long-term water purification process, the surfaces of these MBBR (Moving Bed Biofilm Reactor) reactors may scale. At this time, the activity of the biofilm on the surface decreases, the water flow cannot pass through smoothly, and ultimately the wastewater fails to meet the discharge standards as scheduled. In this article, AquaSust will learn about the causes of scaling on the surface of these media and effective treatment measures. Please read on to learn more.   Causes of Scaling of MBBR Media in Dairy Wastewater   Water Quality: The organic matter in beverage wastewater , under the metabolic action of microorganisms, will produce viscous extracellular polymeric substances (EPS). It acts like glue to promote the aggregation of microorganisms and their adsorption on the surface of the...

What are the Types of Linear Lights?

图片
Introduction In shopping malls, offices, or modern homes, we often see those slender and straight strip - shaped lamps, that is, linear lights . They not only provide bright light but also can be integrated into various decoration styles. Today, Toppo will take you to know about these linear lights and the common types of linear lights on the market.   The Origin of Linear Lighting The origin of linear lighting can be traced back to fluorescent lamps in the 1950s. At that time, fluorescent lamps were used in industrial production because they could illuminate large - area regions. Later, with the popularization of LED technology, people found that LED lighting was more energy - efficient, high - efficiency, and environmentally friendly, and thus developed LED linear lights.   Due to its long - strip shape, LED linear lights can produce long - continuous light. Nowadays, it is often used in various spaces, including offices, retail stores, corridors, and even elevators. Common ...

What are the Advantages of Recessed Lighting?

图片
  Introduction The floor-to-ceiling height of urban residences is often limited. Traditional chandeliers tend to make our space look more oppressive. On the other hand, due to their seamless and tidy appearance, recessed lighting fixtures are becoming a more popular option in modern interior design. In addition to illuminating a room, recessed LED lighting fixtures also offer a variety of aesthetic functions and uses. Today, Toppo is going to explore their structural features and numerous benefits.   What Is Recessed Lighting? Recessed lighting fixtures are usually cylindrical or circular in shape and are designed to provide directional and focused illumination. Unlike traditional fixtures that are directly installed on the ceiling surface, recessed lighting fixtures are embedded in the ceiling or wall and are flush with the ceiling. In this case, the main part of the lighting fixture (the housing and wire components) is hidden, and only the glowing bulb or lampshade can be se...

What is a RF Slip Ring and What are the Types?

图片
  Introduction In applications such as radar, antenna , and wireless technologies, rotating devices need to transmit high-frequency signals (such as radio frequency and microwave signals) between the rotating part and the fixed part. The traditional wiring method will cause the device to get entangled with the cable when it rotates, and the conventional slip rings are difficult to carry high-frequency signals, resulting in signal attenuation and increased interference. To address this issue, RF slip rings have been designed. In t his article , ByTune   will introduc e   the definition, types, and applicable applications of RF slip rings.   What is an RF Slip Ring? An RF slip ring, also known as a high-frequency rotating connector or a microwave rotating joint. Different from traditional electrical slip rings, RF slip rings are specifically designed to transmit radio frequency (RF), microwave, and even millimeter-wave signals. They usually adopt a coaxial or waveguide...

Low Voltage Slip Rings: Types, Features and Common Uses

图片
Introduction Low-voltage slip rings are specifically designed to operate at lower voltage levels, typically up to 1000V AC or 1500V DC. They can continuously transmit current and signals in applications that require rotation, and offer lower resistance, more complete signals, and a compact structure. Today, ByTune wi ll discuss the different types, features, and common applications of low-voltage slip rings.   What Types of Low-Voltage Slip Rings are There? (1)  Pancake Slip Rings P ancake slip rings ’   conductive rings   are arranged in a flat disc shape, and the contact area between the brushes and the ring tracks is smaller than that of conventional slip rings. This results in limited current/power capacity for them. Additionally, the insulation spacing between adjacent ring tracks of these slip rings is small, and they cannot provide a large creepage distance and electrical clearance in a high-voltage environment. Therefore, they are more suitable for transmitti...

Heavy Metals in Wastewater: Causes, Impacts, and Treatment Processes

图片
Introduction In the modern industrialization process, a large amount of wastewater is generated every day. Some of this wastewater contains significant amounts of heavy metals, such as cadmium (Cd), chromium (Cr), copper (Cu), mercury (Hg), and nickel (Ni). If this wastewater is discharged without treatment, the heavy metal components will accumulate in the food chain, harming human health, aquatic organisms, and the ecosystem. Today, AquaSust   will assess the sources and impacts of heavy metal-containing wastewater in this article and introduce some effective treatment methods.   Main Causes of Heavy Metals in Wastewater Industrial activities are the main sources of heavy metals in wastewater, including the following industries: (1) Chemical Manufacturing: This includes the petroleum, paint, dye, and soap industries. The heavy metals in these industries come from various sources, such as raw materials, improper disposal of chemical waste, and leakage from chemical material p...
