Can Leather Wastewater be Treated with a Filter Press

A large amount of wastewater is generated during the leather production process, which contains high concentrations of organic matter, heavy metals, suspended solids and other pollutants. Not only is the composition complex, but the water quality and water volume fluctuate greatly, making it extremely difficult to treat. If discharged directly, it will cause serious damage to the environment, so it must be professionally treated to meet the discharge standards. So, as an efficient solid-liquid separation equipment, can the filter press be used for leather wastewater treatment?

The answer is yes. The filter press is the best equipment for leather wastewater treatment, which is inseparable from its unique advantages. The filter press can separate solid pollutants such as sludge and fiber in leather wastewater from liquid through strong pressure. Compared with other separation methods, the filter press has high treatment efficiency, can greatly shorten the treatment cycle, and improve the treatment capacity. At the same time, the filter press has a significant effect on the dewatering of sludge, especially the membrane filter press. Its unique membrane squeezing technology, after completing conventional filtration, then passes high-pressure air or water into the membrane to perform secondary squeezing on the filter cake, which can greatly reduce the moisture content of the filter cake, efficiently achieve deep separation of solid and liquid, and reduce the difficulty and cost of subsequent sludge treatment.

From an environmental protection perspective, the use of filter presses helps leather wastewater treatment meet strict emission standards. The treated clear liquid can be further processed and reused to achieve the recycling of water resources and reduce the production cost of the enterprise; the separated solid matter can also be reasonably disposed of after treatment to avoid secondary pollution. In addition, the filter press has a high degree of automation and is easy to operate, which can effectively reduce labor costs and labor intensity. Its stable performance and long service life also provide guarantees for the long-term and stable operation of the enterprise. For this reason, the filter press plays an irreplaceable and important role in the field of leather wastewater treatment and has become a widely used treatment equipment in the industry.
