Suspending Shaft-less Screw Conveyor for Wastewater And Sludge Treatment

From April 15 to April 17, 2019, Ryde Environment was honored to participate in the 20th China Shanghai Environmental Protection Association. In this exhibition, Ryde Environment has exhibited its star products, Multi disc screw press, Polymer preparation unit and External rotary drum screen.

On October 19, 2018, Customer from South Asian came to Ryder Environment for a field visit. Amy, the manager of international business development Department of Ryde Environment, expressed warm welcome to customer from South Asian on behalf of the company. The customer inspected the screw type sludge dehydrator, external fed rotary drum screen, DAF equipment and other machine made by Ryde Environment.

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.

Flocculants are most commonly used in wastewater treatment and sludge treatment. In the process of sludge concentrating and dewatering from secondary clarifier, flocculants should be added to mix with sludge evenly and then enter other equipment such as multi disc screw press or belt filter press. This can improve the sludge dewatering effect and enhance the efficiency of sludge dewatering. In the process of using flocculants, there are many factors that will affect the effect of using flocculants.

Flocculants are most commonly used in wastewater treatment and sludge treatment. Flocculant should be added to mix with sludge evenly and then enter other equipment such as multi disc screw press or belt filter press. Flocculants can be divided into inorganic flocculants, organic flocculants and microbial flocculants.

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.

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.

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.

PAM is often used in sewage treatment and sludge treatment. It is necessary to add to mix with sludge evenly and then enter other equipment such as multi disc screw press or belt filter. The function of Polymer preparation unit is to make the powder or liquid flocculants dissolve or dilute into flocculants solution.
