Machine sand industry
With the increasing demand of infrastructure construction in our country, the production of machine-made sand is increasing year by year, but the contradiction between the mass production of machine-made sand waste water and environmental protection and water conservancy flood control is becoming increasingly prominent. Due to the large amount of waste water from machine-made sand, high solid content in waste water, wide distribution range of solid particle size, great difficulty in wastewater treatment, high cost of equipment investment and operation, etc. For many years, it has not been treated well. A large amount of waste water directly enters the river channel, which brings great environmental hidden danger. The filter press of our company has the advantages of low equipment investment and operation cost, low energy consumption, simple and convenient operation, complete recycling of waste water, realizing zero discharge of sand washing waste water, which not only avoids environmental and water conservancy problems, it also greatly saves the consumption of water resources.
