Attached-growth processes (also known as fixed-film processes) are biological wastewater treatment processes with the biomass attached to some type of media. The media normally found at wastewater treatment plants are rock, ceramic, plastic materials, and slag. The growth formed on the media is a mixture of mainly aerobic microorganisms.

Innovative design biological prefabricated wastewater treatment system. Full service easy to install and operate. Cost effective modualar systems reduce space while providing quality results for BOD, TSS and other metrics.

The scope of this comprehensive new edition of Handbook of Biological Wastewater Treatment ranges from the design of the activated sludge system, final settlers, auxiliary units (sludge thickeners and digesters) to pre-treatment units such as primary settlers and UASB reactors. In a suspended-growth system, such as activated sludge processes (also aerated lagoons and aerobic digestion), the waste flows around and through the free-floating microorganisms, gathering into biological flocs that settle out of the wastewater. The settled flocs retain the microorganisms, meaning they can be recycled for further treatment. There are three basic components in the activated sludge process: (1) a biological reactor in which the microorganisms responsible for treatment are kept in suspension and aerated; (2) a clarifier for liquid-solids separation; and (3) a recycle system for returning solids removed from the liquid-solids separation unit back to the reactor. Browse our Biological Treatment Equipment & Systems LEAPmbr for Wastewater LEAPmbr* builds on 25 years of membrane bioreactor experience to deliver the most advanced MBR solution to date. Biological wastewater treatment is an extremely cost effective and energy efficient system for the removal of BOD (Biological Oxygen Demand), since only micro-organisms are used.

MBT plants are designed to process mixed household waste as well as commercial and industrial wastes. Biological Treatment. Aqua-Aerobic Systems has provided more than 1,000 customers with performance proven and cost effective biological treatment systems, capable of effectively removing nutrients, reducing phosphorus and producing reuse quality effluent.

Biological wastewater treatment is an important and integral step of wastewater treatment system and it treats wastewater coming from either residential buildings or industries etc. It is often called as Secondary Treatment process which is used to remove any contaminants that left over after primary treatment.

The biological treatment is located at the periphery in a ring-shaped area while the clarification stage is in the central region. The treatment system is fully expandable for complete biological nutrient removal. The system can also be designed to incorporate aerobic sludge holding, flow equalization, post aeration and chlorine contact chamber.
