What are the Best method to treat slaughterhouse effluent?
Slaughterhouse effluent treatment techniques include primary, secondary, and tertiary treatment, and are analogous to municipal wastewater treatment techniques. The need for primary care is still present, though.
There are many SWW treatment options available after preliminary treatment, and they can be categorized into four main groups: physicochemical treatment, biological treatment, AOPs, and combination processes.
Methods to treat slaughterhouse effluent
· Physiochemical Treatment
By producing an electric current without the use of chemicals, the electrocoagulation (EC) technique has been employed as a low-cost approach for eliminating organics, heavy metals, and pathogens from slaughterhouse effluents.
2: Dissolved Air Flotation
The technique of liquid-solid separation with the addition of air is referred to as "DAF technology." A sludge blanket is created when the fat, grease, and light solids are forced to the surface.
Scum scraping makes it possible to consistently eliminate it. Additionally, flocculants and blood coagulants can be added to the DAF treatment, to increase its capacity to remove COD and BOD by up to 75%.
3: Membrane processes
Membrane techniques are becoming a substitute for traditional wastewater treatment for the meat industry. With overall efficiency of up to 90%, SWW treatment uses a variety of membrane techniques, such as microfiltration (MF), ultrafiltration (UF), nanofiltration (NF), and reverse osmosis (RO), to remove particles, colloids, macromolecules, organic debris, and pathogens.
However, membrane procedures must be supplemented with traditional processes in SWW to remove nutrients.
· Biological Treatment
1: Anaerobic Treatment
It is the ideal method for SWW treatment because anaerobic bacteria break down organic molecules, into CO2 and CH4 in the absence of oxygen, making it useful in treating highly concentrated industrial effluents.
Examples of typical anaerobic procedures for the treatment of meat processing effluents include, anaerobic baffled reactor (ABR), anaerobic digester (AD), anaerobic filter (AF), anaerobic lagoon (AL), septic tanks (ST), and up-flow anaerobic sludge blanket (UASB).
2: Aerobic treatment
Aerobic procedures are widely utilized for nitrogen removal and further treatment after main treatment. It is useless as a main treatment but effective after anaerobic treatment because the amount of oxygen required, and the length of the treatment is proportional to the SWW's strength.
Which method is best to treat slaughterhouse effluent?
When it comes to biological wastewater treatment, sequencing batch reactor (SBR), which uses a fill-and-draw operation, is regarded as an upgraded version of the activated sludge method.
Aeration and sludge settlement happens in the same tank when an SBR operates in pseudo-batch mode. SBRs are run in sequences of the fill-react-settle-draw-idle period. The SBR tank performs the tasks of equalization, aeration, and sedimentation in a time sequence, as opposed to the traditional space sequence of continuous-flow systems, which is one of the main differences between SBR and typical continuous-flow, activated sludge systems.
Because, they can eliminate organic carbon, nutrients, and suspended particulates from wastewater in a single tank, and have low initial and on-going expenses, sequencing batch reactors (SBRs) are recommended as one of the best available methods for slaughterhouse wastewater treatment.
