How to choose the best domestic sewage treatment plant?
An important question for anyone installing a new sewage treatment plant for a new build, or as part of an upgrade of an existing failing septic tank is – What is the best domestic sewage treatment plant?
This is a difficult question to answer, but this article will look at the most important considerations to take into account when buying a sewage treatment plant. They are listed in order of importance.
Best domestic sewage treatment plant – tank material
The tank material is very important. There are four main tank materials. These are GRP [glass reinforced plastic], HDPE [high density polyethylene], PP [polypropylene] and concrete
The best domestic sewage treatment plant is manufactured from either HDPE or PP, and we will discuss why below.
GRP: This is the least desirable material for a sewage treatment plant. GRP is a very old fashioned material, and most tank manufacturers have stopped using it. GRP tanks are made of multiple parts either joined or bolted together. These joints leak over time and the bolts will rust. GRP has a very low impact resistance and can damage easily. GRP can also rot and degrade rapidly in areas with certain types of soil and groundwater. The best domestic sewage treatment plant is definitely not manufactured from GRP.
HDPE: This is an excellent material. This high-density plastic is almost indestructible. But the only risk with HDPE is that it can bend slightly over time. If you are buying a HDPE tank, make sure it has stainless steel reinforcement in the like the Biocell QuickOne. Without a doubt, the best domestic sewage treatment plants are manufactured from HDPE with stainless steel reinforcement.
PP: Polypropylene is as strong as HDPE. If considering buying a PP sewage treatment plant, make sure the tank is a minimum of 8mm thick like the Biocell Bioclean. PP is a low-cost material, so a sewage treatment plant made of PP will be very good value.
Concrete: This is an excellent material but there are some major drawbacks. You need a roadway to the location of the sewage treatment plant for the delivery truck, you need a crane for installation, and the lid is always put on the tank after installation, so if it is not sealed properly there can be major leaks. So, overall concrete is a good material but can be very expensive to install.
Best domestic sewage treatment plant – running costs
Sewage treatment plant running costs are a very important consideration in determining which is the best domestic sewage treatment plant. To give a short answer, the best system on the market is the ClearFox Nature. This is a totally non-electric plant, and it is the only non-electric treatment plant in the world that does not require replacement parts or media.
So, the best non-electric sewage treatment plant is without a doubt the clearfox Nature.
The best electric sewage treatment plant based on running costs is very simple to determine. The power consumption of any sewage treatment plant is listed on the EN12566-3 certificate for the product. This means that you can ignore the misinformation provided by sales agents and you can check this out yourself. The Biocell QuickOne has the lowest energy consumption of any sewage treatment plant available in Europe. But don’t take our word for it. Compare the EN12566-3 certificate with any other system and see for yourself.
So, with regard to effluent quality the best domestic sewage treatment plant is the Biocell Quickone.
Best domestic sewage treatment plant – effluent quality
The effluent quality of any sewage treatment plant is a very important factor. There are a number of parameters measured when determining effluent quality, such as Biological Oxygen Demand, Suspended Solids, Nitrogen, etc. But the parameter of most importance is Ammonia. Ammonia is a highly poisonous substance in sewage. It can kill fish in streams and if it enters groundwater it causes major pollution and can enter drinking water via wells and springs. If you are wondering what ammonia is – it is what people use to remove nail varnish and to clean paint brushes.
As with running costs, all EN12566-3 certificates list the effluent quality of every plant. So, ignore sales pitches and check for yourself. If you do this, you will see that the Biocell QuickOne has the highest level of ammonia treatment currently available. So, protect steams and drinking water in your locality by installing the best domestic sewage treatment plant with regard to effluent quality – the Biocell QuickOne.
