➣How Do Wastewater Recycling Systems Function?

Wastewater recycling is a multi-stage process that employs numerous technologies to treat effluent so that it can be reused in other applications. Primarily, comprehensive wastewater treatment is accomplished in a series of processes known as preliminary, primary, secondary, and tertiary. Here is a brief breakdown of the stages employed to treat domestic or industrial wastewater.

● Removal of large pollutants.

The incoming wastewater is first screened to expel large constituents like wood and glass as well as oil and grease. The expelled elements are cleaned and ultimately disposed of in a landfill. These impurities are extracted using screening systems and this mitigates the untimely fouling of the wastewater recycling system.

● Screening of grit.

Fine particles of sand and stones are hardly filtered out in the bar screening stage. The incoming discharge is passed through a grit chamber which expels grit physically thereby mitigating system fouling.

● Initial clarification.

This process is also referred to as primary clarification. Initial clarification alienates organic constituents from the wastewater in the primary clarifiers. Sedimentation is exploited to separate suspended matter from liquid water. Coagulation and flocculation are processes often employed to speed up sedimentation and increase its efficiency.

The suspended solids settle at the clarifier’s base while other impurities like oil float at the top. The floating pollutants are skimmed off while a sludge removal unit is deployed to extract the suspended solids. In typical wastewater recycling systems, 40% of BOD and 60% of the TSS are removed in primary clarification.

● Aeration.

Aeration involves supplying air or oxygen to amplify the growth of bacteria, which initiates the biological treatment process. The aeration process also facilitates the conversion of NH3 to NO3.

● Secondary clarification.

The wastewater from the aeration tank is driven into the secondary clarifier where the remaining organics settle at the bottom. The primary components of the activated sludge in secondary clarifiers are active bacteria. A section of the active microorganisms is driven back to the aeration tank to keep the treatment process going. The effluent from secondary clarifiers is essentially treated wastewater.

● Sterilization.

The treated wastewater is likely to harbor microorganisms from the activated sludge process. To decrease the microbial count, the effluent is treated through UV water sterilization or chlorination. Click on the link below to watch an illustration of how wastewater recycling systems function.

➣Which Varieties of Wastewater Recycling Systems Do You Provide?

We are an all-around manufacturer of wastewater recycling systems currently providing systems for treating industrial and domestic wastewater. Underneath, we briefly look at the primary categories of our first-rate wastewater recycling plants.

● Sewage recycling plants.

Sewage recycling plants are wastewater treatment systems used to extract pollutants from wastewater discharged from residential and commercial complexes. They integrate chemical, physical and biological processes to effectively treat sewage. Recycled water is often used in irrigation.

● Effluent recycling plants.

Effluent recycling plants are mainly deployed in industries and manufacturing facilities to treat highly polluted effluent. They are mainly used in industries like pharmaceuticals, cosmetics, and textiles. We manufacture effluent treatment systems with diverse volumes to cater to small and large industries. Our systems are rigorously tested before being dispatched to ensure they generate the desired level of treated effluent.

● Activated sludge systems.

Activated sludge systems are wastewater recycling systems that extract impurities from wastewater using microorganisms. They utilize dissolved oxygen to augment the growth of biological floc, which consequently degrades organic elements. We provide residential and industrial activated sludge plants.

● Membrane bioreactor systems.

Membrane bioreactor (MBR) systems are wastewater treatment plants that exploit biological and membrane filtration processes. They eliminate organic pollutants and suspended solids among other unwanted impurities.

● Reverse osmosis systems.

Our comprehensive catalog of reverse osmosis systems includes specialized systems for wastewater treatment. They are pressure-driven systems that alienate dissolved solids from water using semi-permeable membranes.

➣Which Biological Treatment Mechanism is Used in Wastewater Recycling Plants?

Biological wastewater treatment utilizes bacteria to extract organic pollutants from domestic and industrial discharge. However, to effectively treat wastewater using biological methods, other supplemental processes are necessitated. Activated sludge treatment is the primary mechanism exploited in biological wastewater treatment. It is a process that eliminates organics by biodegrading them using microorganisms.

The process of activated sludge treatment commences once the air is pumped from the aeration tank into the wastewater. This propels the growth of bacteria, which consequently digest the organic impurities. The biodegradation of organics occurs in the secondary or final clarifiers. Active bacteria at the base of the clarifier are reintroduced into the aeration tank to propel further treatment. The illustration underneath will help you grasp the concept of activated sludge treatment.

However, innovation has given rise to membrane bioreactor technology, which assimilates biological treatment and membrane treatment. The activated sludge process is exploited in MBR to biodegrade organics, while membrane filtration systems are utilized to eradicate suspended solids. Ultrafiltration systems and microfiltration systems are the preferred membrane systems since their membrane pore size ranges from 0.05 to 0.4 µm.

➣Is Pre-Treatment Mandatory When Using Wastewater Recycling Systems?

Yes. To effectively recycle wastewater and to uphold the optimal performance levels of your wastewater recycling system, pretreatment is mandatory. The preliminary treatment of wastewater extracts large particles like wood, corrosive chemicals, and minerals. It is often accomplished using technologies such as;

● Bar screening.

Bar screening is a conveyer-like process that traps large elements found in untreated wastewater. Mechanical filters are typically installed before the wastewater recycling system to eliminate large pollutants that can possibly foul the system. The expelled particles are cleansed before being discarded in landfills.

● Pressure sand filtration.

Pressure sand filtration is deployed in preliminary wastewater treatment to extract fine grit. The process is carried out using pressure sand filters which extract fine particles of stones and sand as well as other suspended solids.

● Coagulation and flocculation.

Coagulation and flocculation processes are mainly employed to pretreat wastewater prior to sedimentation. Flocculation agglomerates smaller particles into large masses, which can be extracted using sedimentation. Coagulation on the other hand integrates smaller particles by neutralizing their charges. These processes can also be used to pretreat wastewater prior to media filtration.

● Ultrafiltration and microfiltration.

Ultrafiltration and microfiltration are membrane filtration mechanisms dependent on partially permeable membranes with porosities ranging from 0.05 to 0.4 µm. They eradicate suspended matter using size exclusion and are comparatively more productive than conventional media pre-filters.

➣Do You Manufacture Membrane Bioreactor Systems for Wastewater Recycling?

NEWater is a reputable manufacturer and provider of comprehensive wastewater recycling equipment. Our array of wastewater treatment plants includes elaborate membrane bioreactor systems. MBR systems are wastewater treatment plants that extract organic pollutants and suspended solids through biological treatment supplemented by membrane filtration. In membrane bioreactor systems, the objectionable organics are removed using bacteria that digest organic compounds. This is attained using aeration and activated sludge treatment.

Suspended solids in the discharge are extracted using microfiltration and ultrafiltration processes. Semipermeable membranes characterized by pore sizes ranging from 0.05 to 0.4 µm seize the suspended solids to ultimately produce high-level effluent. The membrane filtration process is pressure-reliant. The integration of these two processes makes membrane bioreactor systems quite efficient than orthodox activated sludge plants.
