Bemical Sewage Plants are engineered to transform raw sewage (both black and grey water) into high-quality effluent suitable for irrigation. With the product's original architect now part of the Bemical team, we bring over 20 years of experience in the sewage recycling industry and a footprint across 11 African countries to your project.

Unlike traditional septic tanks that merely store waste, a Bemical plant is a living ecosystem. The process follows a precise four-stage flow:

1. Collection & Primary Settlement: All raw sewage is collected in a primary septic tank where fats, oils, and organic solids are separated.
2. Biological Reactor (Moving Bed Bio-Reactors): Submersible pumps move the effluent at a controlled rate into the heart of the plant. Here, specialised media provides a massive surface area for our high-potency bacteria to colonise and digest organic matter.
3. Clarification: The treated water enters a clarification zone where any remaining fine solids settle out, leaving clear water.
4. Sterilisation: The final stage utilises Ozone or Chlorine sterilisation to eliminate pathogens, ensuring the outflow is safe for reuse.

The efficiency of the Bemical system is verified by its ability to reduce contaminants to levels far below municipal requirements.

• Irrigation Ready: Convert your waste into a resource. The final effluent is ideal for gardens, dust suppression, or agricultural use.
• Small Footprint: Our modular design allows for high-capacity treatment in a fraction of the space required by traditional leach fields.
• Odourless & Silent: The advanced aeration and biological digestion process eliminate the foul gases typically associated with sewage.
• Modular & Scalable: Systems can be expanded easily to accommodate anything from a single residential home to large industrial camps.

• Below Ground: For a discreet, "invisible" installation.
• Small Footprint: Ideal for rocky terrain where excavation is difficult.
• Above Ground: The advanced aeration and biological digestion process eliminate the foul gases typically associated with sewage.
• Containerised: Modular "Plug & Play" units for rapid deployment in remote mining camps or rural infrastructure projects.

Effective wastewater treatment relies on a two-stage biological process to remove nitrogenous pollutants, which are primary drivers of environmental contamination.

Stage 1: Nitrification (Aerobic Process)

Ammonia (NH₃) is a nitrogenous compound that must be removed or significantly reduced to protect aquatic ecosystems. This occurs through nitrification, an aerobic process where specialised nitrifying bacteria carry out a two-step chemical conversion:

1. Ammonia and other nitrogen compounds are first converted into Nitrite (NO₂).
2. Nitrite is then further oxidised into Nitrate (NO₃).

Because nitrification requires molecular oxygen (O₂) to achieve these conversions, this stage is performed in highly aerated environments.

Stage 2: Denitrification (Anoxic Process)

Once nitrification is complete, denitrification must occur to remove the nitrate from the wastewater. Unlike the previous stage, this is an anaerobic process that takes place in an anoxic state (an environment absent of free oxygen).

During this phase, denitrifying bacteria reduce the nitrate into molecular nitrogen (N₂) gas. The mixture of denitrified activated sludge and raw wastewater is then aerated, allowing the harmless nitrogen gas to be released into the atmosphere.

Our sewage plants don’t just move waste; they transform it. Through a scientifically balanced cycle of Nitrification and Denitrification, we use specialised bacteria to convert harmful ammonia into harmless nitrogen gas. This two-stage biological process ensures your effluent meets the strictest environmental standards for irrigation and discharge.

Safe Drinking Water, Anywhere on Earth

Bemical’s mobile purification system is a patented, world-class solution designed to provide clean, healthy drinking water in remote areas, disaster zones, or off-grid communities. Developed over eight years of intensive R&D, this system destroys bacteria, viruses, and hydro-toxins without the use of harmful chemicals.

The Technology: Chemical-Free Sterilisation

Unlike traditional systems that rely on chlorine or reverse osmosis, our unit combines a patented steriliser with specialised filter media.

• Pathogen Destruction: Effectively eliminates bacteria and viruses through a non-chemical sterilisation process.
• Metal Removal: Integrated filter media removes toxic metals from the water supply.
• Fine Filtration: The standard system filters down to 2 microns, with an optional upgrade available for 1-micron absolute filtration.
• Automated Maintenance: The unit features an automated backwash system, ensuring the filters remain clean with minimal manual intervention.

Technical Specifications & Performance

Designed for high-impact deployment with low operational requirements.

Awards & Recognition

This technology has been internationally recognised for its social and technical innovation, featuring as a finalist in:

• PWC “Vision to Reality” Awards
• SAB Foundation’s Social Innovation Awards
• Agri-Water Innovation Challenge

Ideal Applications

• Disaster Management: Can be air-deployed for immediate response in crisis zones.
• Rural Infrastructure: Providing sustainable water solutions for schools and clinics without access to the grid.
• Remote Work-sites: Reliable water for mining camps or agricultural projects.

While Reverse Osmosis is a well-known water treatment method, it often presents significant challenges in remote or off-grid environments due to high maintenance needs, chemical reliance, and water waste. Bemical’s patented sterilisation technology offers a more sustainable and cost-effective alternative.

Efficiency & Operational Comparison

The Bottom Line: Total Cost of Ownership

• Maintenance Savings: Traditional systems can accrue heavy costs through membrane fouling and chemical dosing. Bemical’s only major maintenance is a once-yearly replacement of the sand, carbon, and metal removal media, typically costing less than USD 1,000.
• Environmental Footprint: Because our system does not use chemicals to destroy hydro-toxins, the discharge from the automated backwash does not contaminate the local environment, unlike the concentrated brine produced by RO units.
• Durability: Designed for mobility in rugged areas, the system can be deployed on trailers, skids, or in secure shipping containers to prevent theft and vandalism.

Ready to Deploy?

Whether for disaster management, rural community support, or remote mining camps, the Bemical Mobile Water Purification System provides immediate, sustainable results where traditional infrastructure fails.

A spill doesn’t have to become a legacy of contamination. Bemical’s spill management solutions are designed for rapid response, ensuring that industrial leaks—from oils and fuels to hazardous chemicals—are contained and managed using 100% natural and sustainable materials.

The Power of Natural Absorbency

Unlike traditional synthetic pads that end up as permanent waste, our spill kits utilize organic, biodegradable absorbent materials. This approach not only provides superior wicking action but also aligns your facility with global sustainability standards.

• Rapid Capture: High-performance natural fibres that pull contaminants away from surfaces instantly.
• Eco-Friendly: Made from renewable resources that minimize your operational carbon footprint.
• Zero Waste to Landfill: Integrated with our bioremediation agents, captured waste can often be treated on-site rather than dumped.
• Versatile Response: Tailored kits for hydrocarbons, general chemicals, or marine environments.

Spill Kit Range & Specifications

Choose the right kit based on your specific risk profile and waste management goals.

A Complete Solution

For maximum efficacy, our spill kits can be paired with Green Lock Hydrocarbon Converter. By applying Green Lock directly to the spill area, hydrocarbons are encapsulated and rendered inert, ensuring that runoff is non-toxic and the environment is protected from the moment the spill occurs.

When a spill occurs, every second counts. Bemical provides a three-stage protocol that integrates our high-performance absorbent kits with our proprietary biological converters to ensure that accidents are contained, neutralized, and restored without leaving a toxic footprint.

Is your site prepared for a "worst-case" scenario? Bemical offers site-specific spill risk assessments to ensure you have the right volume of natural absorbents and Green Lock on hand.
