- Reduces discharge values
- Helps to meet stringent discharge limits
- Reduces wastewater charges
If your company needs to treat trade effluent to reduce wastewater charges or meet stringent discharge consent limits, we can design a site-specific treatment process to biologically treat effluent and wastewater to meet our customer’s individual needs.
Water Tecnik have successfully used several forms of biological treatment processes for wastewater and effluent treatment across a wide range of industries.
Bacterial Processes in Wastewater Treatment
Primary processes such as screening, settlement or floatation use mechanical or chemical treatment systems to remove sediments, suspended solids or substances such as grease & oil from the wastewater. Pre-treatment can effectively remove most insoluble contaminates from the effluent stream.
Biological effluent treatments use of bacteria and other small organisms to break down the remaining organic substances in wastewater, such as sugars and starches. These organic substances contribute to COD (chemical oxygen demand) levels present in effluent. These contaminates are often referred to as soluble COD and cannot be removed by pre-treatment (primary processes).
Several types of biological processes can be used to treat wastewater, which include.
- Activated Sludge Process (ASP)
- Membrane Bio Reactor (MBR)
- Trickle or Percolation Filter
Secondary treatment is commonly used when companies must conform to lower discharge consent limits which pre-treatment alone cannot meet. These instances are normally when a company is discharging directly a water course, such as a river.
Sometimes however it may be required, or can be economically advantageous to biologically treat effluent for sewer discharge.
Each of our customers have their own individual requirements, so please don’t hesitate to get in contact to discuss yours with our process engineer.
