For almost 20 years, AdPower We have grown to become a diverse sewage treatment solutions company, integrating Sewage Management solutions into a Total Water Management package.

Our team of industrial designers & engineers will design a sewage treatment solution tailored to your needs. We will take a full evaluation of your exact requirements, carry out site surveys as required, and produce detailed reports, technology specifications and drawings to design a complete water solution.

Sewage Treatment Plants

AdPower has developed Sewage Treatment Plants (STP) to convert raw sewage into clean water that can be used for irrigation, cooling of heat exchangers, toilet flushing and discharge to rivers and streams. Our decentralized, standard, and custom-designed wastewater treatment solutions are reliable and cost-effective. As well as conventional plants, we specialize in solutions that are modular, scalable, and quick to deploy.

Our STPs are equipped with full instrumentation for real-time, remote, or on-site monitoring of key process parameters. They can be fully automated and controlled by our innovative smart operation suite, which allows for real-time response and optimized savings in operating costs

AdPower offers economically advantageous and technically proven solutions for every application, from complete sewage treatment plants to containerised, modular STPs:

Sewage Treatment – explained

Sewage treatment plant processes fall into two basic types:

Anaerobic Sewage Treatment

Sewage is partly decomposed by anerobic bacteria in a tank without the introduction of air, containing oxygen. This leads to a reduction of Organic Matter into Methane, Hydrogen Sulphide, Carbon Dioxide etc. It is widely used to treat wastewater sludge and organic waste because it provides volume and mass reduction of the input material to a large extent.. The methane produced by large-scale municipal anerobic sludge treatment is currently being examined for use in homes and industry, for heating purposes. Septic tanks are an example of an anerobic process, but the amount of methane produced by a septic tank (it is only the SLUDGE at the bottom that produces methane) serving less than 100 people is miniscule. In addition to this, septic tank effluent still contains about 70% of the original pollutants and the process smells very badly, due to the Hydrogen Sulphide, if not vented correctly. The effluent produced by this process is highly polluting and cannot be discharged to any watercourse. It must be discharged into the Aerobic layer of the soil (within the top metre of the ground) for the aerobic soil bacteria to continue the sewage treatment via the aerobic process below.

Aerobic Sewage Treatment

In this process, aerobic bacteria digest the pollutants. To establish an aerobic bacterial colony you must provide air for the bacteria to breathe. In a sewage treatment plant, air is continuously supplied to the Biozone either by direct Surface Aeration using Impellers propelled by pumps which whisk the surface of the liquid with air, or by Submerged Diffused Aeration using blowers for air supply through bubble diffusers at the bottom of the tank. (The most modern aerobic sewage systems use natural air currents and do not require electricity, though these are only used for small scale sewage systems at the moment. Once again, the general public leads the way!) Aerobic conditions lead to an aerobic bacterial colony being established. These achieve almost complete oxidation and digestion of organic matter and organic pollutants to Carbon Dioxide, Water and Nitrogen, thus eliminating the odour and pollution problem above. The effluent produced by this process is non-polluting and can be discharged to a watercourse.
