Build a sedimentation tank at the construction site

Build a sedimentation tank at the construction site, first discharge the sewage into the sedimentation tank, remove suspended matter and oil substances and neutralize them, and then discharge them into the river after testing to meet the discharge standards.


During the drilling and pouring process, a screen is used to separate small gravel, sand and other solid particles in the mud, and the mud is discharged to the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank for full sedimentation. During the construction process, the first sedimentation tank, the second sedimentation tank, and the third sedimentation tank are cleaned in time by an excavator, and the cleaned sediment is transported to the evaporation tank, and after natural dehydration and solidification, it is transported to the storage yard or the waste dump.


For the abandoned mud water, flocculants are added to the mud water. Since mud water is a suspended liquid containing a certain amount of fine mud particles in water, polymer flocculants are a type of water-soluble polymers. When mixed with mud water, the flocculants have the functions of bridging, netting, adsorption and electrical neutralization, which can destroy the stability of mud water and make mud particles quickly condense and settle from the water, thereby achieving the effect of mud-water separation.

River Water Cyclone Desander

 A cyclone desander is a sand removal device that combines cyclone flow and filtration. It is primarily used to remove solid particles and sediment from groundwater, including groundwater and other water sources. It is suitable for water-source heat pump systems, central air conditioning circulating cooling water, chilled water systems, winter heating and cooling circulating water systems, and industrial cooling circulating water systems. It is widely used in many industries, including the chemical, environmental protection, and food industries, achieving remarkable results in water treatment, including sand removal, turbidity reduction, solid-liquid separation, and sediment separation. Cyclone Desander Concept: A cyclone desander, also known as a cyclone desander or desander, is a device that uses the principle of screening solid particles in the medium as they rotate within the desander. Combining cyclone flow and filtration, it achieves remarkable results in water treatment, in...

Water-Saving Sand Washing Plant

Choosing water-saving equipment and integrating recycling functions is the key to fundamentally reducing water consumption. Select advanced sand washing equipment Bucket-type sand washing machine: The structure is simple, with almost no wearables except for the screen, and the failure rate is low. It adopts a circulating water cleaning method and is one of the relatively more water-efficient mainstream choices currently. Integrated sand washing equipment: This type of equipment integrates sand washing, fine sand recycling, dehydration, and even wastewater treatment functions into one, significantly simplifying the process flow. For example, some new equipment uses built-in bubble flushing technology to improve the flushing effect and avoid secondary cleaning waste caused by incomplete cleaning. Mandatory water recycling system Modern sand washing equipment usually comes with a water recycling system, which can collect, filter, and reuse water during the cleaning cycle. This approach ca...

The difference between quartz and mica

Mica and quartz are common minerals that play an important role in mineralogy. Although they are both silicate minerals, there are clear differences between them. First, mica and quartz are very different in appearance. One of its distinguishing features is that mica exhibits a layered structure that can be easily peeled off into thin flakes. Quartz, on the other hand, is a uniform crystal with no layered structure. Additionally, mica is usually dark in color, such as black, brown, or green, while quartz is usually clear or white. Secondly, mica and quartz also differ in their physical and chemical properties. The hardness of mica is usually between 2.5 and 4, which is relatively easy to be scratched; while the hardness of quartz is very high, 7, which is a very hard mineral. In addition, mica has good refractive properties and electrical properties, while quartz is an excellent piezoelectric material.
