Non electric sewage treatment plant reviews

A sewage treatment plant works by circulating air to encourage bacterial growth in order to break down sewage. The idea is to produce effluent and that effluent should be cleaner and more environmentally friendly. It works in a similar way to a traditional septic tank, but with a few important modifications. Sewage treatment plants treat the waste of commercial buildings or a large number of household residences, depending on their size.

Why do Sewage Treatment Plants need to be built?

Connecting to main sewers should be the first thought for anyone constructing a new property. They're usually the most cost-effective and dependable way to handle your wastewater. Getting a mains sewer hook-up, on the other hand, isn't always possible. In some cases, the distance from the nearest sewer or the land configuration prevents your property from being serviced by a mains sewer.

Sewage treatment facilities and other solutions can help with this. The operation of a sewage treatment plant allows it to be erected nearly anywhere, as long as there is an electrical connection.However, due to a scarcity of resources, sewage treatment plants must be advanced in order to save energy. As a result, everyone will benefit from a non-electric sewage treatment plant.

In three steps, a non-electric wastewater treatment plant effectively cleans sewage.

Step 1: Raw sewage is pumped into the primary chamber, where suspended solids settle. Primary sludge sinks to the bottom, where anaerobic digestion reduces its bulk. The leftover wastewater is directed to the restricted outlet, which leads to the bioreactor for treatment in the second stage.

The wastewater is buffered at the restriction outflow. This ensures that, independent of any hydraulic peaks, an even flow of wastewater is forwarded to the bioreactor throughout the day.

Step 2:The major chamber's restriction outlet feeds the compensator, which in turn fills the distribution boxes in regular flushes. The wastewater drips through the openings in the distribution boxes' bottoms, allowing it to flow equally through the sedimentary media elements below.

Step 3: Bacteria develops on the surface of the media to form a biofilm that cleans the wastewater by eating the leftover organic materials when air is introduced via natural ventilation. This is referred to as the cascaded plug flow, because the water is completely cleaned in one go.

Simultaneously, the system will biodegrade and eliminate any secondary sludge that results. The outlet is used to extract residual quantities. These, on the other hand, are well below legal requirements and hence are not deemed problematic.

Similarly, if operated appropriately, the system will not require replacement parts or material for its entire lifetime. The materials of the system, which are made up of fixed media and passive aeration units and are balanced with a filling device that controls catabolism, biomass distribution, and flowrate, will always be effective.

Benefits of Non electric sewage treatment plants

1: Low maintenance - The plant contains no technical wear parts and will never need replacement parts during its lifespan. The primary sludge also requires less frequent disposal as a result of the reduction procedure.

2: Quick start-up — The plant achieves peak cleaning performance in a short amount of time. You can also add enzymes to the support medium to speed up the process even more.

3: Easy Installation- If your site is not on an incline, we attach a pump shaft to a pump downstream to lift the water to outlet height.

4: High quality Effluent- A disinfection module can be put downstream to allow the clean effluent to be reused as raw water.

5:Low-cost maintenance —Traditional sludge disposal is eliminated by employing filter bags in the primary chamber and composting the filter waste.

Some of the latest sewage treatment systems do not need electricity to power the treatment process. They use natural air currents to aerate the sewage and are non-aquatic Filtration Sewage Treatment Plant

How Sewage Systems Work

All sewage treatment systems work by using naturally occurring aerobic (oxygen breathing) bacteria to digest the pollutants in the sewage. In order for the aerobic bacteria to live, oxygen must be available for them to breathe.

Electric Systems

All electrically operated treatment plants use electricity to aerate the sewage liquid. This is done by one of the following methods:

• Rotating discs through the sewage, by means of a motor/gearbox inside the plant. These discs are half-submerged in the liquid sewage. Aerobic bacteria grow on the discs and take in oxygen when the disc rotates out of the liquid. They are an old technology, now made by only one manufacturer.
• Pumps which spray liquid sewage over plastic shapes, with a lot of surface area, called 'Media'. The sewage liquid takes up oxygen during the spraying process and bacteria grow on the media surface. They absorb the oxygen and digest the sewage pollutants as they wash over them. This is also old technology, uses a LOT of electricity and manufactured by only one company now.
• Air blowers which bubble air through the sewage liquid. The sewage liquid may, or may not have media added to it. If the liquid has media within the biozone chamber, then the plant is called a 'Submerged Aerated Filter' (SAF) and if it doesn't, it is likely to be an Activated Sludge' treatment system. The latter is the most modern type of treatment plant.

Non-Electric Systems

These are all Filter Systems. In ALL cases, the sewage flows from the house to a 2 stage settlement tank, to separate the solids from the liquids and the liquid effluent then flows to the tank that contains the filter, or multiple filters. These plants use the following as filtration media:

• Coco Husk Fibre. This is bio-degradable and, as such, needs regular, expensive maintenance and replacement as it rots.
• Rockwool. This is non-degradeable, but disintegrates easily into dust and squashes down over time, due to the weight of water it contains. It is expensive to replace. It was designed for Aquaponic growing of specialist plants, where it is used for one plant growth cycle only.
• RDX filter media. This is specifically manufactured for long term foul water filtration and is much cheaper to replace than Rockwool cubes. It is also Non-Degradeable.

The sewage liquid flows through the filter material, which traps the pollutant particles. Air is supplied through air channel passages and penetrates the filter material. The aerobic bacteria that develop then have air and food and they digest the pollutants.

Performance of Non-Electric Sewage Treatment Systems

The performance of non-electric systems varies enormously between the makes. One Non-Electric plant only just scraped through he EN 12566-3 Test, with Ammoniacal Nitrogen levels right on the limit of what is allowed in the UK. See sewage treatment plant SELECTION.

Another manufacturer made sure that their plant was tested through a German Summer, as higher temperatures make all plants work far more efficiently - but your plant has to work during the winter as well.

One manufacturer also sells their smallest plant as a 6 person, when it was only tested with 750 litres of sewage per day - enough sewage for 5 persons (5 x 150 litres/person/day), but not for 6.  No wonder that the Test Results are good as it was under-loaded.

We insisted that our FilterPod was tested through a German Winter instead, where temperatures are below freezing for much of the time. It was also tested for the correct number of people.

Be very careful when choosing a non-electric plant, as it is a minefield.

Installation Costs

Non-electric sewage treatment systems are roughly twice as expensive to buy and to install, as they are all a 2 tank system, instead of a single tank installation.

Maintenance and Servicing

Contrary to the various manufacturer's claims, all filters block over time and cannot 'self-clean' adequately to avoid filter replacement. The filter media must be partially replaced every year and fully replaced every 10 years.

Servicing costs for ALL non-electric plants are more expensive than for electric plants as a result and must be carried out annually, so get a quote for the maintenance costs before you buy a non-electric plant.
