Product Description

• Disposal of sewage from life and industry is a difficult and costly problem
• As a result, we are seeking new solutions to address these pain points to reduce costs and risks and improve operational performance.
• WSZ Series Sewage Treatment Equipment will be one of your best choices
• Advantage: compact design, small area, low cost, reliable operation, high automation as well as simple maintenance while discards defects in traditional sewage treatment technology
• 

         

• WSZ treat wastewater in batches within the same vessel. This means that the bioreactorand final clarifier are not separated in only space but also in a timed sequence. The installation consists of at least two identically equipped tanks with a common inlet, which can be alternated between them. While one tank is in settle/decant mode the other is aerating and filling.
• This is the new biological processes that used to remove contaminants and produce treated wastewater (or treated effluent) that is safe enough for release into the environment.

• activated sludge+ Suspended Biofilm process
• Activated sludge/ biofilm process represents a renewable process with the combination of activated sludge process and biofilm process. The activated sludge is not easy to be carried away by the water.
• It is concluded that the combined activated sludge/ biofilm process has better resistance to shock loads, high nitrogen removal efficiency and consistent effluent quality.

• WSZ is a multi-chamber reactor unit that makes use of highly concentrated microorganisms to degrade organics and remove nutrients from wastewater to produce a high-quality effluent. To maintain aerobic conditions and to keep the activated sludge suspended, a continuous and well-timed supply of oxygen is required.
• if Oxygen is prevented from reaching the water, allowing anaerobic bacteria to grow, which can cause health concerns, emit foul odors. So we added a lot of aerators to produce oxygen, which can quickly treat organic matter.
• 
  
  
   
• The best way to install the equipment is underground.
• The WSZ's process is appropriate in almost every climate. However, treatment capacity is reduced in colder environments.
• Biological oxidation processes are sensitive to temperature and, between 0 °C and 40 °C, the rate of biological reactions increase with temperature. Most surface aerated vessels operate at between 4 °C and 32 °C.
• 
• 
• Applicability
• Because of economies of scale and less fluctuating influent characteristics, this technology is more effective for the treatment of large volumes of flows.
• Sludge Handling and Disposal - you need other equipment if you will either wet haul or dewater the sludge and arrange for disposal.
