What is a containerized wastewater treatment plant?

A containerized wastewater treatment plant is a uniquely designed effluent treatment system that is preassembled in standard containers. Wastewater treatment plants generally condition the discharge from industries and homes to make certain the effluent can be reinjected into the conventional water cycle. For most industries, especially those dealing with chemical products, wastewater treatment systems are mandatory. This is because failure to abide by the existing discharge quality and disposal regulations can result in heavy fines or unnecessary legal battles.

Containerized wastewater treatment plants are highly revered in different sectors thanks to their enhanced movability, ease of operation, and efficiency. They deploy numerous technologies in distinct stages to effectively treat your wastewater. Ordinarily, they extract elevated levels of suspended solids, dissolved solids, BOD, nitrates, and phosphorus among others.

How Do Containerized Wastewater Treatment Plants Work?

The treatment of effluent using containerized wastewater treatment plants is typically accomplished in numerous stages; preliminary, primary, secondary, and tertiary. Underneath, we are going to take you through the comprehensive wastewater treatment process.

● Preliminary screening.

The treatment of industrial or domestic discharge commences with bar screening, which removes large constituents that might damage the plant’s components. The removed elements include glass pieces, fragments of wood, and plastics, which are later cleaned before being discarded in a landfill.

● Grit extraction.

Grit refers to small-sized particles of sand or stone. These constituents are hardly extracted in preliminary screening and they can clog the primary water treatment components. Therein, they are extracted using physical processes before being appropriately disposed of.

● Primary clarification.

Primary clarification principally seeks to extract suspended solids using the process of sedimentation or gravity settling. Solid constituents suspended above the effluent are extracted before the wastewater is subjected to biological treatment. Constituents that settle at the base of the primary clarifiers are known as sludge and they are eliminated using sludge removal systems. Ordinarily, this process extracts 60% of the suspended solids and 30-40% of the BOD.

● Aeration.

To invoke the biological treatment of wastewater, air or oxygen is pumped into the wastewater. This encourages the proliferation and growth of bacteria as well as the conversion of NH3 to NO3. The growth of bacteria is essential since they are subsequently used to break down organic constituents.

● Secondary clarification.

Secondary clarification follows the same working principles as primary clarification. The treated wastewater is injected into the secondary clarifiers whereby the remaining organic elements are extracted through gravity settling. Biomass of microorganisms used in the biological treatment process settles as activated sludge at the base of the secondary clarifiers. A portion of the activated sludge is reintroduced into the aeration tank while the remaining portion is disposed of or treated.

● Wastewater sterilization.

To complete the treatment of wastewater, UV water sterilization or chlorination is exploited to do away with harmful microorganisms. To be precise, this process seeks to extract bacteria remaining in the contact chamber. If you employ chlorination, you must test the chlorine levels of your effluent to ensure you do not exceed the set limits.

A containerized membrane bioreactor plant integrates membrane filtration and biological treatment to produce high-grade effluent conforming with effluent regulations. The membrane filtration systems employed in membrane bioreactor plants have porosities with sizes ranging from 0.05 to 0.4 µm. Ultrafiltration filter systems and microfiltration systems are the chief membrane-based treatment systems exploited to extract suspended solids in MBR plants. Biological processes i.e. activated sludge treatment are utilized to break down biodegradable organics. These plants operate on two process configurations;

• Side-stream or
• Immersed configuration.

● Containerized activated sludge plants.

These are typical containers with activated sludge plants installed inside. In these systems, a multi-chamber reactor vessel containing microorganisms is used to extract nutrients and break down organic pollutants in your wastewater. These systems comprise aeration tanks, which supply oxygen to the microorganisms used to degrade organics. Containerized activated sludge plants are ideal for industrial as well as municipal wastewater treatment.

● Containerized effluent treatment plants.

Containerized effluent treatment plants are systems specialized to treat industrial wastewater. They permit the reintroduction of industrial wastewater back into the ecosystem in line with discharge laws. They can also generate a quality of effluent that can be reused in other applications like irrigation. We manufacture standard and customized effluent treatment plants with distinct volumes to accommodate the demands of small and large industries.

● Containerized reverse osmosis systems.

Deploying containerized reverse osmosis systems in industrial wastewater treatment elevates the quality of effluent produced. They remove numerous yet distinct pollutants and are primarily used in tertiary treatment. They extract elevated levels of microorganisms, TDS levels, nutrients, and minerals.

What is the Role of Containerized Wastewater Treatment Plants?

The aftermath of environmental pollution resulting from the inappropriate disposal of industrial wastewater has been felt globally. To avert further damage, varying laws on wastewater disposal have been instituted. The regulations primarily require industries with concentrated effluent as a by-product to treat their effluent prior to disposal or reuse. Containerized wastewater treatment plants help industries and households adhere to the respective environmental laws. As such, users are protected from needless heavy fines and devastating legal confrontations.

In addition, they help protect the ecosystem from industrial pollution. By extracting harmful pollutants, they ensure workers and neighboring communities are safe. Wastewater treatment systems also mitigate the transmission of waterborne diseases by destroying pathogenic microorganisms.

Do Containerized Wastewater Treatment Plants Utilize Membrane Bioreactor Technologies?

Yes. Membrane bioreactor treatment has become a popular wastewater treatment technology in recent years. This technology incorporates both biological treatment and membrane filtration to effectively extract organic elements and elevate TSS levels. Ordinarily, activated sludge treatment is employed as the biological treatment mechanism while ultrafiltration systems or microfiltration systems are employed to extract suspended solids.

Membrane bioreactor systems are commonly divided into vacuum and pressure-driven systems. Pressure-driven systems are essentially cartridge systems installed outside the bioreactor. Gravity-driven or vacuum MBR systems are typically immersed and often utilize flat sheet membranes or hollow fiber membranes. Fully functional membrane bioreactor plants have 10 to 11 sub-systems, which include screening equipment, aeration equipment, disinfection systems, and clarifiers.

The biological process exploited by MBR plants is essentially driven by oxygen. Diffusers or aeration tanks pump oxygen into the system to proliferate the growth of microorganisms. The microorganisms are in turn exploited to degrade organic compounds and scrub membrane surfaces. These systems are comparatively smaller than conventional activated sludge plants and their effluent quality is top-notch. Here is an illustration of how membrane bioreactor treatment is utilized in wastewater treatment.

Which Post-Treatment Technologies Are Utilized in Containerized Wastewater Treatment Plants?

To comply with some stringent effluent regulations, you might need to post-treat the wastewater discharged by your containerized wastewater treatment plant. Underneath, we are going to discuss some of the most effective and widely used post-treatment mechanisms in wastewater treatment.

● Reverse osmosis.

Reverse osmosis is a pressure-driven process that alienates dissolved solids and other pollutants from liquids using partially permeable membranes. Employing this process to polish treated wastewater removes objectionable impurities like microorganisms, minerals, nutrients, dissolved solids, and metals.

● UV water sterilization.

Ultraviolet (UV) sterilization is a disinfection mechanism employed to extract pathogenic microorganisms from water. It is a non-chemical process that employs germicidal radiation to kill microorganisms. UV water sterilizers achieve this by terminating the DNA cells of microorganisms thus inhibiting their growth or reproduction.

● Water deionizers.

Water deionization gets rid of ionic contaminants in water by substituting them with non-pollutant ions. Typical water deionizer systems consist of anion exchange resin and cation exchange resins. The anion exchange resin holds hydroxyl (OH-) ions, which replace anionic impurities like chloride and nitrate. The cation exchange resin holds (H+) ions, which replace cationic contaminants like calcium and sodium.

How Does Activated Sludge Treatment Work in Containerized Wastewater Treatment Plants?

Activated sludge treatment is a biological process that extracts organics from wastewater using microorganisms to break them down. Activated sludge plants deployed in wastewater treatment are chiefly made up of three components. An aeration tank, which is essentially the bioreactor, supplies air to catalyze the growth of bacteria. A settling tank or clarifier, which alienates activated sludge from treated wastewater. Finally, they have a return system used to inject activated sludge from the clarifier to the aeration tank as an influent.

A solution of the mixed liquor is formed once air or oxygen is pumped into the treated effluent and mixed with microorganisms. Biodegradable impurities such as organic compounds are degraded by the microorganisms resulting in effluent with low levels of organics. Watch the following animation video to get a better understanding of activated sludge treatment.
