Wastewater Treatment System
Wastewater treatment equipment efficiently purifies contaminated water through processes like filtration, sedimentation, and chemical treatment, ensuring the removal of pollutants before safe disposal or reuse, which including:
●  Screens in wastewater treatment
  Settling tank
  Dissolved air flotation
  Sludge screw press
●  Chemical dosing system
  Integrated sewage treatment equipment
  Sludge mud scraper
  Waste water decanter


Screens in wastewater treatment

Screens are important industrial wastewater equipment in wastewater treatment to remove solid particles and other impurities from wastewater. Their surface contains many small holes or openings to allow water to pass through while blocking larger particulate matter from passing through.

Settling tank

In the early stage of waste water purification system, the settling tank allows the solid particles in the wastewater to settle to the bottom, thus achieving the initial solid liquid separation, and also helps to remove impurities such as suspended solids, sediment, sand and gravel.

 Dissolved air flotation

Air float is a wastewater precess equipment used in wastewater solutions, it introduces tiny bubbles into the wastewater, so that the suspended substances float to the surface, so as to achieve the effect of solid-liquid separation and purification.

Sludge dewatering equipment

Screw press, as waste water treatment machine, working principle is to use the spiral blades on the spiral shaft to gradually push and squeeze the solid matter in the waste water, so that it moves along the direction of the spiral axis and is finally discharged from the outlet of the machine.

Dosing device system

The dosing device is common wastewater treatment machine in the sewage treatment process, which is used to add chemical agents to the wastewater to promote the condensation, precipitation, oxidation or neutralization of pollutants, so as to achieve the purpose of purifying the water quality.

Integrated sewage treatment equipment

An integrated wastewater treatment plant, also known as an integrated wastewater treatment system, is an innovative solution that integrates multiple sludge water treatment units in a single plant, and easy to install and move.

Sludge mud scraper

Mud scrapers are commonly used in sludge water treatment to separate sludge from sewage and scrape it from the bottom of the treatment unit to the centralized sludge tank. This wastewater equipment is mainly used in settling tanks, air flotation tanks to remove sludge.

Waste water decanter

The working principle of the decanter is based on physical filtration, which prevents the passage of solid particles through the micropores of the filter screen or the pores of the filter element, thus achieving solid-liquid separation. The equipment used in wastewater treatment.


Chemical dosing system

Chemical dosing system is the key of industrial wastewater treatment equipment for wastewater treatment process, which can achieve water quality improvement through automatic dosing of chemicals. It includes:
  • Chemical storage
  • Dosing pumps
  • Piping
  • Control systems
  • Instrumentation
Ensure accurate dosing of chemicals. These systems can be used to assist in coagulation, precipitation, disinfection, pH regulation, oxidation and other processes to remove contaminants, improve water quality and meet regulatory requirements. Chemical dosing systems improve treatment efficiency and reduce waste water discharge, and are widely used in sewage treatment plants, drinking water treatment, industrial processes and environmental protection.
SD, as one of wastewater treatment equipment manufacturers can provide the solution of design requirements and site planning.
  • Municipal Wastewater Treatment
Sewage treatment equipment used in municipal wastewater treatment where wastewater from homes, businesses is treated to remove contaminants and pollutants. It can produce clean water for discharge into the environment or for reuse.
  • Industrial Wastewater Treatment
Many industries generate wastewater with unique contaminants and characteristics. Wastewater treatment equipment is used to address these specific needs, such as removing heavy metals, chemicals, and pollutants from industrial effluents.
  • Agricultural Wastewater Treatment
In agriculture, wastewater is generated from activities like animal farming and crop irrigation. Waste water purification system is used to remove organic matter, nutrients, and pathogens to prevent contamination of water bodies and soil.
  • Oil and Gas Industry
The oil and gas sector produces large volumes of wastewater, which may contain hydrocarbons, heavy metals, and other pollutants. Specialized treatment equipment is employed to treat produced water, ensuring compliance with environmental regulations.
  • Food and Beverage Industry
Wastewater from food processing plants can be rich in organic matter and nutrients. Industrial wastewater equipment is used to reduce the organic load and make the water safe for discharge or reuse.
  • Pharmaceutical Industry
Pharmaceutical manufacturing generates wastewater containing complex chemicals and pharmaceutical residues. Wastewater treatment equipment is necessary to remove these contaminants and protect the environment.
  • Mining Industry
Mining activities produce wastewater that can be highly acidic and contain heavy metals. Industrial wastewater treatment equipment is used to neutralize acidity and remove contaminants.
  • Power Plants
Power plant water treatment includes water source collection, cooling water, boiler water, wastewater treatment, desulfurization wastewater treatment, water recycling, wastewater discharge control, water quality monitoring, environmental protection.
Great wealth roots in purification of sewage, which turns the Earth into a healthy planet.
