Shangqiu ceramsite filter material manufacturer/Shangqiu ceramsite filter material price

Ceramsite filter material is made of high-quality pottery clay, clay, viscose solvent, etc., which is processed by mass grinding, screening, and calcining. It has the characteristics of hard surface, microporous interior, and high porosity. Using aerobic activated sludge as the inoculation, the treatment effect of an aerated biological filter can be achieved within two weeks of water inflow.
1. Main features of ceramsite filter material
. The particles are round, uniform, rough in surface, multi-microporous, well-developed internal pores, and large specific surface area, resulting in strong adhesion ability of biological bacteria, fast reproduction, and film-hanging efficiency. The ammonia nitrogen removal effect under high, low temperature and low turbidity conditions has reached the domestic advanced level. The working cycle is long and the cycle water production is large, generally -/.
.The accumulation density is light and the strength is high, so the backwashing energy consumption is low, the water head loss is small, and the head loss of the cleaning material is only //.
.Strong interception ability, average level/.
.High filtration rate, generally -/ up to 3/.
.The backwash water consumption is low, only 3- times that of quartz filter material.
.Stable chemical properties, strong acid and alkali resistance, and long service life.

4. Application of ceramsite filter material
In the treatment of steel rolling wastewater, Generally, the methods of sedimentation, coagulation, and biological ceramsite filter materials are used. After removing suspended matter and oil from the wastewater, it is then cooled and recycled. The quality of treated water requires turbidity and oil content below mg/L.
Several representative systems for treating hot rolling wastewater are as follows:
. Wastewater ~ iron pit, sedimentation tank, cooling tower ~ recycling.
B. Wastewater ~ iron pit ~ coagulation sedimentation tank and two cooling towers are recycled.
Wastewater ~ iron pit ~ sedimentation tank ~ filter ~ cooling tower ~ recycling.
Some factories first use iron pits to treat hot rolling wastewater. After sedimentation and separation of most of the oxidized iron scale and oil in the wastewater, they then use pressure ultra-high-speed biological ceramsite filter materials to treat it. The treated water is cooled by a cooling tower. After recycling. For oily wastewater generated during the cold rolling process, a conditioning tank is generally used to remove most of the floating oil in the water, and then coagulation and flotation methods are used to remove the emulsified oil. The floating oil content in the cold rolling wastewater is about mg/L, and the turbidity is -0. After the wastewater stays in the regulating tank for 3 minutes, the oil content in the effluent is about mg/L. The effluent water after treatment by coagulation and flotation, The oil content is mg/L and the turbidity is -°C. If it undergoes secondary treatment, treated water with good water quality can be obtained.
