WASTEWATER TREATMENT SYSTEMS
STAGES OF WASTEWATER TREATMENT SYSTEMS
- Preliminary Treatment
Wastewater underwent preliminary treatment in removing large solids, fats, oil, and grease in order not to disrupt the whole wastewater treatment system. Treatment operations in this stage include coarse screening and grit removal.
- Primary Treatment
Sedimentation is a process that takes place in this stage wherein settleable organic and inorganic solids are removed, same with materials that float in the wastewater known as scum by skimming.
- Secondary Treatment
The primary goal of secondary treatment is to remove any remaining organic matter and suspended particles from the effluent following initial treatment. The removal of biodegradable dissolved and colloidal organic materials via aerobic biological treatment techniques is a common part of secondary treatment, which often comes after primary treatment. Biological processes are commonly associated in this treatment stage.
- Tertiary Treatment
When certain wastewater elements that cannot be removed by secondary treatment need to be eliminated, tertiary and/or advanced wastewater treatment is used. To get rid of nutrients, extra suspended particles, refractory organics, heavy metals, and dissolved solids, separate treatment techniques are required.
COMMON BIOLOGICAL TREATMENT PROCESSES IN THE PHILIPPINES
- Conventional Activated Sludge (CAS) Process
The aeration tank, where wastewater is combined with air to activate microorganisms, is the initial stage of a CAS system. The organisms that are breaking down the wastewater clash with one another, generating bigger particles known as flocs that have a greater ability to break down the biological components of the wastewater. The secondary clarifier or settling tank comes after the aeration basin. Microorganisms with their adsorbed organic material settle during this phase. The clarifier's output water is sent to facilities for ultimate discharge and disinfection, or to further tertiary treatment facilities for even more filtration.
- Sequencing Batch Reactor (SBR) Process
A fill-and-draw activated sludge technology for wastewater treatment is the sequencing batch reactor (SBR). This approach involves adding wastewater to a single "batch" reactor, treating it to get rid of unwanted elements, and then releasing it. Using a single batch reactor, equalization, aeration, and clarity may all be accomplished. Two or more batch reactors are employed in a preset order of operations to maximize the system's performance. Industrial and municipal wastewater have been effectively treated using SBR systems. They are particularly well suited for wastewater treatment applications with intermittent or low flow conditions.
- Moving Bed Biofilm Reactors
A combination of biofilm medium and traditional activated sludge procedures forms the foundation of the extremely efficient biological water treatment method known as MBBR. Water may be handled in both aerobic and anaerobic settings in this fashion. The MBBR method makes use of a large number of polyethylene biofilm carriers. Within an aerated mixed wastewater treatment basin, these carriers move together. Each carrier offers a protected carrier that promotes the development of both heterotrophic and autotrophic bacteria inside the cells. The procedure becomes more efficient and productive thanks to this technology.
OUR SOLUTION
Microbe-Lift IND is a highly active liquid culture consortium design specifically for use in all industrial and municipal wastewater systems. Microbe-Lift IND increases overall microbial oxidation rates, significantly increasing organic degradation performance. This novel microbial consortium provides reductions in final effluent BOD, COD, SS, and improves settling in final clarifiers, while reducing waste sludge volume in difficult to degrade compounds such as fatty acids, various chemical compounds, hydrocarbons and fibrous matter. Microbe-Lift IND enhances the biological oxidation of slow to degrade organic compounds significantly improving overall system performance and stability.
