At Hydromo, we’re committed to pioneering sustainability in water treatment. We offer a range of technologies that help treat and recycle discharge waters back into your process for reuse, recovering all fluid waste by utilizing our state-of-the-art filtration and thermal technologies.
Wastewater must be treated because about 80% of it flows unfiltered into lakes, rivers, seas and oceans and this leads to environmental hazards. It causes a build-up of organic and inorganic contaminants, heavy metals and pathogens in these water bodies which contaminate freshwater and harm the aquatic ecosystem.
Rampant urbanisation and industrialisation have led to an enormous increase in the wastewater from both domestic setups (sewage) and industries (effluent). The output of water is much cleaner, more environmentally friendly effluent. Wastewater treatments also ensure that you comply with industry standards and regulations by Pollution boards, drafted to save the planet’s fast-dwindling freshwater reserves. Recover around 95% of your liquid waste for reuse, treat and retrieve valuable byproducts from your waste like salts, and produce a dry, solid cake for easy disposal.

The Need for Wastewater Treatment
About 80% of wastewater flows unfiltered into our natural water bodies, leading to a build-up of organic and inorganic contaminants, heavy metals, and pathogens. This contamination harms the aquatic ecosystem and poses a threat to our freshwater reserves. With rampant urbanization and industrialization, the volume of wastewater from both domestic and industrial sources has increased enormously.
Our Solution
Our wastewater treatment processes produce cleaner, more environmentally friendly effluent, ensuring compliance with industry standards and regulations set by Pollution Boards. We help you recover around 95% of your liquid waste for reuse, treat and retrieve valuable by-products from your waste like salts, and produce a dry, solid cake for easy disposal.

MBR: Membrane Bioreactor
The Membrane Bioreactor (MBR) is a powerful solution in the field of wastewater treatment. It combines a membrane process, such as microfiltration or ultrafiltration, with a biological wastewater treatment process, the activated sludge process. This combination is now widely used for municipal and industrial wastewater treatment.
How Does MBR Work?
MBR for wastewater treatment is a combination of a suspended growth biological treatment method, usually activated sludge, with membrane filtration equipment. These are typically low-pressure microfiltration or ultrafiltration membranes. The membranes perform the critical solid-liquid separation function, which in traditional activated sludge facilities is accomplished using secondary and tertiary clarifiers along with tertiary filtration.
There are two general types of MBR systems: vacuum (or gravity-driven) and pressure-driven systems. Vacuum or gravity systems are immersed and normally employ hollow fiber or flat sheet membranes installed in either the bioreactors or a subsequent membrane tank. Pressure-driven systems are in-pipe cartridge systems located externally to the bioreactor.
What is an MBR System?
An “MBR System” is considered to be a complete and integrated membrane unit with related components necessary to allow the process to function as desired. An MBR system often comprises ten or eleven sub-systems and includes fine screening, the Membrane Zone, and in most cases, some type of post-disinfection process.
MBBR: Moving Bed Biofilm Reactor
The Moving Bed Biofilm Reactor (MBBR) is a type of wastewater treatment process that consists of an aeration tank with special plastic carriers. These carriers, known as Fluidized Aerated Bed (FAB) media, provide a surface where a biofilm can grow.
How Does MBBR Work?
The carriers are mixed in the tank by the aeration system, ensuring good contact between the substrate in the influent wastewater and the biomass on the carriers. To prevent the plastic carriers from escaping the aeration, a sieve is necessary on the outlet of the tank.
MBBR as a Biofilm Process
MBBR is considered a biofilm process, similar to other conventional biofilm processes for wastewater treatment such as trickling filter, rotating biological contactor (RBC), and biological aerated filter (BAF). Biofilm processes generally require less space than activated sludge systems because the biomass is more concentrated, and the efficiency of the system is less dependent on the final sludge separation.
However, other biofilm processes can experience bioclogging and build-up of head loss. Unlike these, MBBR systems don’t need a recycling of the sludge, which is often required in activated sludge systems.
Retrofitting with MBBR
The MBBR system is often installed as a retrofit of existing activated sludge tanks to increase the capacity of the existing system. This makes it a versatile and efficient solution for wastewater treatment.
SBR: Sequencing Batch Reactors
Sequencing Batch Reactors (SBR) are a type of activated sludge process used for wastewater treatment. SBR reactors treat wastewater, such as sewage or output from anaerobic digesters or mechanical biological treatment facilities, in batches.
How Does SBR Work?
Oxygen is bubbled through the mixture of wastewater and activated sludge to reduce the organic matter, measured as Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). The treated effluent may be suitable for discharge to surface waters or possibly for use on land.
The process begins with water entering through the inlet valve and the tank being filled while mixing is provided by air blowers. Aeration of the mixed liquor is performed during the second stage by the use of fixed or floating mechanical pumps or by transferring air into fine bubble diffusers fixed to the floor of the tank.
In the third stage, no aeration or mixing is provided, and the settling of suspended solids starts. During the fourth stage, the outlet valve opens, and the “clean” supernatant liquor exits the tank.
Nitrification and Phosphorus Removal
Aeration times vary according to the plant size and the composition/quantity of the incoming liquor, but are typically 60 to 90 minutes. The addition of oxygen to the liquor encourages the multiplication of aerobic bacteria, which consume the nutrients. This process encourages the conversion of nitrogen from its reduced ammonia form to oxidized nitrite and nitrate forms, a process known as nitrification.
To remove phosphorus compounds from the liquor, aluminum sulfate (alum) is often added during this period. It reacts to form insoluble compounds, which settle into the sludge in the next stage.
ASP: Activated Sludge Process
The Activated Sludge Process (ASP) is a tried and tested methodology that has been in use for the last eight decades worldwide. This technology allows for several modifications to cater to all the special requirements available.
How Does ASP Work?
ASP involves sludge recirculation and aeration, which requires an uninterrupted power supply and careful monitoring of the reactor sludge levels. It is a robust and flexible technology that can be adapted to a wide range of wastewater types and conditions.
Efficiency of ASP
ASP is highly efficient in removing contaminants. It removes 80-90% of the bacteria and 90-99% of the viruses, significantly reducing the biological load in the treated wastewater.
EcoBud: Advanced Sewage Treatment System
EcoBud is an advanced, low-powered, fully automated, and low-maintenance sewage treatment system developed by Hydromo.
How Does EcoBud Work?
The treatment of effluent in EcoBud is based on natural biological augmentation, which requires very low power. It works on a combination of processes:
– Anaerobic Digestion: This process involves microorganisms converting organic matter into biogas in the absence of oxygen in a primary settling tank.
– Aerobic Biological Oxidation: Following anaerobic digestion, the effluent undergoes aerobic biological oxidation.
– Clarification and Polishing: The effluent is then clarified and polished using natural filters of sand and fibers.
The system includes pretreatment of effluent using an oil and grease skimmer, primary clarifier, fixed bed bioreactor, and MBBR-based biological treatment of the sewage. The final water is polished by multi-grade bed filtration.
EcoBud is a testament to our commitment to sustainability and innovation in water treatment.
FAQs (Frequently Asked Questions)
An STP is a facility that treats wastewater (sewage) from communities, businesses, and industries. It removes harmful contaminants and pollutants before releasing the treated water back into the environment or for reuse.
STPs play a crucial role in protecting public health and the environment. Untreated sewage can contaminate water sources, spread diseases, and harm aquatic life. STPs help ensure safe and sustainable water management.
STPs typically employ a multi-stage treatment process:
Primary Treatment: Separates large solids and organic matter through physical processes like screening and settling.
Secondary Treatment: Breaks down organic matter using biological processes involving bacteria and microorganisms.
Tertiary Treatment: Provides additional purification for specific uses, such as removing nutrients or disinfecting the water.
The treated wastewater can be:
Discharged into rivers or streams, meeting regulatory standards.
Reused for non-potable purposes like irrigation or industrial processes.
STPs require regular maintenance to ensure optimal functioning. This may involve cleaning equipment, replacing filters, and monitoring treatment processes.
A malfunctioning STP can release untreated wastewater, causing environmental and health risks. Regular maintenance and proper operation are crucial to prevent such issues.
Yes, STPs come in various sizes and configurations based on capacity, treatment requirements, and local regulations. Such as MBR, MBBR & SBR.
Modern, well-maintained STPs such as we have at Hydromo shouldn’t have strong odours. However, older facilities or those experiencing issues might emit unpleasant smells.
