Flocculants are most commonly used in wastewater treatment and sludge treatment. For example, the first step in the use of multi disc screw press or belt filter press is to add a certain amount of flocculant into the sludge to make the sludge flocculate into flocs, and then further treat the flocs. In use, it is necessary to dissolve the solid flocculant into a certain concentration of viscous water solution.
Nowadays, environmental problems are becoming more and more serious, so sludge dewatering is becoming more and more widely used. Sludge dewatering machines include Plate and frame sludge dewatering machine; Belt Filter Press;Centrifugal sludge dewatering machine;Multi Disc Screw Press.
The treatment of Sludge from Sewage-treatment is becoming a thorny problem. After long-term exploration and testing, A number of sewage treatment plants built in the early stage have still not found a good disposal plan. General sludge treatment process of Sewage-treatment Plant : Sludge concentration -> Sludge dewatering -> Sludge drying -> Sludge transportation -> Sludge landfill. Mud scraper and concentrator are usually used in concentrating stage. Multi disc screw press and belt filter press are usually used in dewatering stage. Sludge dryer is usually used in drying stage. There are fewer and fewer resources for storage, disposal and landfill. Enhanced supervision by environmental protection authorities around the world has led to unprecedented growth and expansion of sewage treatment worldwide. We will discuss this issue from several aspects.
On November 15, 2018, a set of screw type sludge dehydrator equipment ordered by Southeast Asian customers was successfully delivered in Ryde Environment. This equipment has applied Ryde Environment's patent technology and will be put into operation in local large-scale municipal projects in early 2019.
Dewatering removes water from sludge making it easier to handle and less expensive to transport, to compost, to incinerate or to dispose of in a landfill. the main types of sewage dehydrator are screw type sludge dehydrator, belt filter press, gravity belt thickener, and so on. Here we introduce you some main advantages of the Screw type sludge dehydrator.
With the development of the pharmaceutical industry, pharmaceutical waste water has become one of the important sources of pollution. It is a good choice to use screw type sludge dehydrator to treat pharmaceutical sludge.
