The high moisture and oil content of sludge in food factories is a common problem. Food factories produce a certain amount of wastewater and sludge during the production process. These sludges usually contain high moisture, and their moisture content can reach more than 95%. Sludge with high moisture content not only takes up a lot of space, but also increases the cost of treatment, because most of the weight and volume are composed of water. In order to effectively manage and treat these sludges, solid-liquid separation is usually required, and the sludge is dehydrated by centrifuges, filter presses and other equipment to reduce the moisture content in the sludge. The treated sludge, if it meets the relevant standards, can be used for agricultural fertilization, land improvement or as an energy material.
Traditional inorganic flocculants, such as lime, iron salts, aluminum salts, etc., may cause problems such as increased salt content in the filtrate, changes in water conductivity, and high salt content in the mud cake. If used as organic fertilizer, it may cause negative effects such as soil compaction, which also affects resource reuse. Thermal drying will increase energy consumption and increase operating costs.
Sludge dewatering agent is a chemical agent specially used to improve the efficiency of sludge dewatering. It is essentially a highly efficient cationic polymer that can change the physical and chemical properties of sludge, thereby promoting the separation of water from sludge, achieving sludge reduction without increasing the salt content.
Food factory oily sludge conditioner can significantly reduce the moisture content of sludge, and can even reduce the moisture content of sludge from more than 90% to 40%-60%. It can significantly improve the dewatering efficiency and reduce the energy consumption and processing time of dewatering equipment. Improve the dewatering performance of sludge, making the dehydrated mud cake easier to further handle and dispose of, such as drying, incineration or resource recycling. It has a wide range of applications and has good adaptability to different types of sludge and water quality.
