Advanced Sequencing Batch Reactor ASBR

  • The best choice for high-quality wastewater treatment and minimum investment and operation cost is the advanced SBR Advanced Technology (ASBR).
    ASBR has a registered record in terms of performance on a global scale.
    ASBR is an optimized biological process for most domestic, municipal and industrial refinement units. This system has been successfully implemented for small, medium and large urban areas. ASBR is used for modular development, replacement and upgrading of existing refinery capacity as well as a pre treatment for the strong industrial wastewater.

Urban and domestic waste water applications:

  • Rural communities, towns and cities
  • Airports and military centers
  • Commercial and residential buildings
  • Schools, hospitals and large stores
  • Septic tanks waste water treatment
  • Residential centers and hotels
  • Restaurants and recreational centers
  • Apartments and complexes

Industrial applications:

  • Food and drink
  • Paper and textile
  • Petrochemicals, refineries and paints
  • Wastewater from anaerobic treatment
  • Pharmaceutical and sanitary
  • Electronic

ASBR process and design capabilities:

  • Increasing the proper formulation of solids and, at the same time, preventing the bulking process because of the ability to select biological regions that will lead to a high quality of treated wastewater.
  • The removal of biological nutrients includes nitrification, denitrification and phosphorus removal
  • Less tanks and less space occupancy compared with conventional sludge treatment by up to 30%
  • High aeration efficiency and reduced energy consumption
  • The minimum equipment will be easy to maintain and easy to operate.
  • Strong stainless steel latches provide long and reliable durability.
  • Freely selectable rectangular, square, circular, single or multiple tanks make this system flexible.
  • Capacity from 20 to 190 thousand cubic meters per day.
  • After the commissioning of the wastewater treatment plant, after-sales services will include an evaluation and analysis of the output data from the refinery to ensure optimal process performance. In addition, connecting to the Internet port and through SCADA on the control panel provides remote service capability.

Consulting services for SBR processes and equipment:

  • Conceptual, Primary and Detailed Process Design
  • Manufacturing and supplying equipment
  • Project management services during implementation
  • Collaboration during launch
  • Personnel training services
  • After-sales service and customer support
    Operation and maintenance services
  • Process optimization
  • Remote control and data analysis
  • Evaluation of system performance

Operation of the cassette filter type MBR modules

8-Cleaning without Chemicals

  • Carefully defined bubble size cleans the membrane surfaces
  • Simultaneous addition of oxygen into the activated sludge is ensured
  • The need for chemical cleaning is kept to an absolute minimum

Principle of filtration

Water containing solid particles flows through the filter cloth/sieve of the given structure which has openings of a certain size. The filter cloth traps impurities which are bigger than openings in the filter cloth while smaller particles, including water, flow through the filter out. As the filter cloth slowly becomes clogged by the increasing amount of filtered impurities, the filter cloth must be backwashed so it can work again.

SS (mg/l), mesh (micrones)

Suspended solids (SS) are in mg/l and show how many SS (e.g. flocs and other debris) are in one liter of water. It is just a reference parameter. It is also important to know what solids look like and select the mesh accordingly.

Secondary filter layer
Filter capacity is greatly influenced not only by the volume but also by the nature of filtered SS. What matters is their size (flat particles tend to clog openings more easily than round ones), mechanical strength (compact particle can be filtered better than non-compact slimy ones) and the proportion of small and big particles in the total volume of influent. If a certain number of compact solids, bigger than the mesh openings, occur, it can result in a thin layer of sludge – secondary filter layer, which is capable of catching solids which are considerably smaller than the size of mesh openings. It is therefore advisable to choose a filter with a greater filter area so the filter idle time is as long as possible and an efficient secondary filter layer can form on the inner side of the mesh. This layer is flushed down to the sludge channel during backwash.
