The Ultimate FAQ Guide for Residential Wastewater Treatment Systems.

Residential complexes generally produce three types of wastewater; greywater, blackwater, and yellow water. Domestic effluent mainly constitutes kitchen waste, human waste, soaps, oils, and used bathroom water. Disposing of this wastewater without adequate treatment threatens the welfare of neighboring populations as well as the environment.

To put an end to environmental pollution, relevant authorities have instituted regulations that modulate discharge quality and disposal methods. Our write-up today elaborates on the distinct wastewater treatment systems you can invest in to treat your residence’s effluent.

➣What is a Residential Wastewater Treatment System?

A residential wastewater treatment system is a water-cleaning plant specialized to extract organics, suspended solids, and other pollutants from liquid waste drawn from households. Just like typical wastewater treatment systems, they permit the reinjection of wastewater back into the water cycle without the risk of further pollution.

Primarily, residential wastewater treatment systems treat your discharge in four phases, preliminary, primary, secondary, and tertiary treatment. This ensures that the effluent you dispose of or reclaim is of the highest quality and up to the set threshold.

They are quite similar to municipal or industrial wastewater treatment plants except for size and design. Modern residential wastewater treatment systems employ technologies such as activated sludge treatment and membrane bioreactor treatment, which result in high discharge quality.

When manufacturing our systems, we adhere to quality standards set by regulatory authorities like NSF/ANSI 40. This makes certain you are guarded against legal action or heavy fines for contravening wastewater disposal regulations.

➣What Are the Stages of Cleaning Wastewater Using Residential Wastewater Treatment Systems?

Treating wastewater is typically accomplished in a number of successive phases. The number of stages or phases may differ depending on the grade of effluent desired or demanded by the local authorities. Underneath, we take you through the comprehensive stages involved in residential wastewater treatment.

● Bar screening.

Bar screening is ordinarily the first stage in residential discharge treatment. It seeks to extract contaminants that are conventionally large-sized to mitigate fouling other components of the treatment plant. This is attained using bar screens, which filter out large solids like wooden fragments and plastics. The ejected impurities are discarded in landfills.

● Grit removal.

The second phase entails eliminating fine fragments of stones and sand using physical barrier filters. This prevents interruptions in service flow rates as well as premature damage to other equipment.

● Primary clarification.

Primary clarification seeks to alienate the solid organic contaminants from the wastewater. The influent devoid of grit and large solids are injected into the primary clarifiers. The solid pollutants sink and settle at the bottom of the clarifiers where continuous pumping is undertaken to avoid impacting the alienation process. The sludge is then ejected and often used as fertilizer.

● Aeration.

Aeration is the fourth stage and it includes injecting oxygen into the aeration basin. This encourages the propagation and growth of bacteria. The bacteria subsequently break down the organic contaminants to produce carbon dioxide and water.

● Secondary clarification.

The treated influent from the aeration tank is driven into secondary clarifiers, which extract the remaining suspended solids through sedimentation. Some of the activated sludge in secondary clarifiers is driven back to the aeration basin thereby elevating bacterial concentration. The wastewater departing the secondary clarifiers is considerably high-quality effluent.

● Disinfection.

The wastewater from the secondary clarifiers has a bacterial concentration that could be harmful. In this stage, the wastewater is sterilized using chlorination or UV water sterilization. In chlorination, chlorine is injected into the water consequently killing the microorganisms. In UV water sterilization, germicidal rays discharged by the UV lamps exterminate the genetic composition of the microorganisms.

● Discharge disposal.

Finally, the treated effluent is reinjected into the water cycle or environment. The effluent is first tested to ensure it complies with the effluent quality regulations. Watching the following video will broaden your understanding of wastewater treatment.

➣What Are the Advantages of Residential Wastewater Treatment Plants?

Ideally, residential wastewater treatment plants are highly beneficial systems with far-reaching rewards realized by the user as well as the ecosystem. They provide cost-efficient and reliable solutions to environmental pollution. Beneath are some of the highly appreciated rewards of residential wastewater treatment systems.

• They generate first-rate effluent with no devastating effects on the environment.

• They hardly necessitate maintenance and are pretty durable.
• They are power-efficient and can be used to supply an alternative source of fuel (biogas).

➣What Are the Main Components of Residential Wastewater Treatment Systems?

Residential wastewater treatment systems are typically manufactured with variations depending on the characterization of the respective wastewater. As such, the components in different plants may be dissimilar. Underneath, we look at the primary components that build a functional residential wastewater treatment system.

● Screening equipment.

Screening systems are imperative in wastewater treatment systems. They extract conventional large impurities such as plastics and wood fragments. Typically, screening equipment is deployed in the preliminary treatment of influents.

● Chemical feed.

Typically, residential wastewater treatment systems comprise a chemical feed. The role of the chemical feed is to inject reagents that aid in coagulation, flocculation, and precipitation. The flocculants and coagulants employed help in sedimentation, which extracts suspended matter.

● Filtration systems.

Traditional filtration systems such as pressure sand filters as well as membrane filtration systems like ultrafiltration systems are deployed in wastewater treatment plants to eradicate traces of suspended solids.

● pH adjustment units.

pH adjustment units regulate the acidity of your wastewater using chemical reagents. Ordinarily, pH adjustment systems utilize lime or sodium hydroxide. They make certain your effluent meets the quality standards set by your respective authorities.

● Post-treatment systems.

Post-treatment systems are mainly deployed to polish treated wastewater and ensure it meets the stringiest of regulations. Typically, systems such as UV water sterilizers and reverse osmosis systems are deployed to eradicate harmful microorganisms and dissolved solids respectively.

● Control panel.

The control panel is an interface that you can use to operate the residential wastewater treatment plant. The control panel installed on your plant depends on the automation level of your systems i.e. fully automated or semi-automated. Customized residential wastewater treatment systems tend to have additional components.

➣Which Types of Septic Systems Are Used in Residential Wastewater Treatment Systems?

Septic wastewater treatment systems are underground tanks that provide basic treatment to wastewater from residences. Typical septic systems are made of plastic, concrete, or fiberglass. Beneath are some of the widely used septic wastewater treatment systems.

● Conventional septic systems.

These systems are commonly used in individual households and small commercial enterprises. They are made of a septic tank and a drain field. A drain field is a subsurface infiltration system that utilizes stones or gravel to filter out suspended solids. Underneath the stones and gravel, lies a layer of soil with microbes that degrade the organics in the effluent.

● Chamber septic system.

Chamber systems fall under gravel-less drain-field systems. They are easy to construct and are cost-efficient in terms of carbon footprint. They are made of numerous interlinked chambers filled with soil on all sides and on top. The wastewater from the septic tanks is treated by the microbes from the surrounding soil.

● Aerobic treatment systems.

Aerobic treatment systems are pretty similar to municipal wastewater treatment plants. The principal difference is their conventional small size. They include an anaerobic tank, which pumps oxygen into the treatment system thereby encouraging the growth of bacteria. The bacteria degrade the organic impurities ultimately generating water and CO2.

There are over 10 septic wastewater treatment systems. Underneath is a list of the other systems.

• Mound systems.
• Drip distribution units.
• Recirculating sand filter plants.
• Community systems.

➣What Are the Treatment Mechanisms Employed in Residential Wastewater Treatment Systems?

Residential wastewater treatment systems typically incorporate several water treatment systems to extract the broad variety of pollutants found in domestic effluent. These distinct processes are employed either in the pretreatment, primary treatment, or post-treatment phases. Underneath is a brief description of these first-rate mechanisms.

● Activated sludge treatment.

Activated sludge technology treats domestic effluent using biological floc such as bacteria and aeration. This process gets rid of objectionable organic matter through degradation, which is carried out by aerobic microorganisms. An aeration tank supplies oxygen to the treated influent thus prompting the flourishing of microorganisms. These microorganisms, in turn, break down the organics resulting in a high-quality discharge devoid of organic waste.

● Membrane bioreactor (MBR) technology.

Membrane bioreactor treatment integrates semi-permeable membrane treatment and biological water treatment to extract suspended constituents and organic matter. The membrane-filtration processes deployed are mainly ultrafiltration and microfiltration. The UF filters eliminate the suspended solids and are preferred over conventional media filters due to their high cut-off range. The biological process deployed to extract organics is often conventional activated sludge treatment.

● Reverse osmosis.

The process of reverse osmosis is chiefly employed in the post-treatment phase. It is a pressure-dependent process that extracts up to 99.7% of dissolved solids using partially porous RO membrane filters. Reverse osmosis is technically the opposite of osmosis i.e. rather than the water flowing from lowly concentrated streams towards streams with higher concentrations, it flows from the highly concentrated stream. Additionally, it extracts minerals, viruses, bacteria, organic chemicals, and metals.

● Ultraviolet water sterilization.

UV water sterilization is chiefly employed as a post-treatment technique in wastewater treatment. Using germicidal rays, UV water sterilization kills 99.99% of living microorganisms by destroying the DNA cells.

➣Which Pre and Post-Treatment Processes Are Integrated with Residential Wastewater Treatment Systems?

For effective treatment of wastewater, the primary wastewater treatment system must be assimilated with pretreatment and post-treatment technologies. Due to the characterization of domestic wastewater, the supplemental processes employed are quite advanced. Here are some of the approved pretreatment and post-treatment processes.

● Screening.

Screening is typically employed in preliminary wastewater treatment to eliminate suspended solids with large dimensions. This process extracts pollutants such as wood fragments, glass pieces, and plastics.

● Coagulation and flocculation.

Coagulation and flocculation are pretreatment processes ordinarily deployed prior to filtration or sedimentation. Coagulation brings particles together by neutralizing charges while flocculation forms an agglomerate of particles through stirring.

● Media filtration.

Media filtration employs different layers of media to remove finer elements after screening has been carried out. Typically, gravity sand filtration and multimedia filtration are used to pretreat wastewater.

● Water disinfection.

Activated sludge treatment employs bacteria to degrade organic impurities. These bacteria and other microbial organisms can cause illnesses hence they must be extracted before the wastewater is disposed of or reused. Chlorination and UV water sterilization are the disinfection mechanisms commonly employed in residential wastewater treatment systems.
