Wastewater Treatment Primary Sedimentation Tank Dirt Interception Cleaning
Brief Introduction
Located in Yixing, an advanced and beautiful city of Jiangsu Province, China, Longdai Co., Ltd is a processing equipment supplier of petrochemical industry specialized in environmental processing &integrating independent research and development, design, general contracting, environmental protection equipment manufacturing, and relevant material supply.
Application
Compared with the traditional sand filter, the continuous flow sand filter has a great breakthrough. It is a continuous filtration equipment integrating coagulation, clarification and filtration. It uses the principle of upflow flow and uses a single homogeneous filter material. Filtration and sand washing are carried out at the same time, and it can run continuously and automatically for 24 hours. No need to stop and backwash. The ingenious sand lifting and washing structure replaces the traditional high-power backwashing system, with extremely low operating energy consumption, easy management, and unattended operation. It is widely used in the fields of drinking water, industrial water, sewage treatment and water reuse treatment.
Structure and Working Principle
The continuous quicksand filter system can be installed independently or as a filter component in muddy water.
When installed independently, it is composed of a tank and internal filter components. The internal filter components include inlet and outlet pipes, water distributors, sand washers, flushing water outlet pipes, and air lift pump casings, etc., made of stainless steel or glass fiber reinforced plastic.
The tank is suitable for small-scale filtration. It operates with a single filter or multiple filters in parallel. The tank is easy to install and does not require large-scale civil construction, saving construction time.
When used for large-scale filtration, the filtration system adopts a concrete structure. The internal components are made of stainless steel or glass steel.
When this type of filter system is installed, all filter units share a sand bed. The filtering system operates in groups, and each group can operate in parallel or independently. Fully adapt to filtration requirements.
Control System
The continuous flow sand filter control system consists of two parts: an electrical control cabinet and an air control cabinet. One electric control cabinet controls one or several air control units, and one air control cabinet controls one or more sand filter units.
The electrical control cabinet has the basic functions of controlling the start, operation and alarm of the continuous quicksand filter. When the continuous quicksand filter is operating normally, the electrical control cabinet guarantees continuous flushing; when there is an abnormality in the operation process, the alarm signal should be transmitted to the control box, Subsequent procedures will issue instructions to stop the filtration system running through the operator or the central control system provided by the customer.
Packing and Delivery
1. Waterproof packing with the international export standard by 20ft, 40ft, 40hp container. Equipment Fittings, Electric Motor and Power Cabinet will be packed in Wooden Case or Iron Box. Other Equipment will be packed by Color-Stripes Plastic Cloth.
2. The whole plant machinery size are large as normal, so we will use Waterproof cloth to pack all of them. The motor, gear box or other easily damaged parts, we will put them into box. We have a professional shipping department, they will try their best to save your container quantity.
