One2Clean Sewage Treatment Plant Being Installed

Choosing the right sewage treatment plant for your property is an important decision that impacts not only the functionality of your home but also the environment. In this blog, we will compare two leading sewage treatment plants in the UK: the GRAF UK One2Clean Sewage Treatment Plant and the Klargester Biodisc Sewage Treatment Plant. Both of these products have a strong reputation for efficiency and sustainability, but they serve different needs depending on the situation.

While this comparison will provide a detailed, unbiased analysis, it’s worth acknowledging that we represent GRAF UK. However, the goal is to offer readers an honest, comprehensive guide to help them make an informed choice, regardless of brand preference. Let’s dive into the specifics.

Technology

The GRAF UK One2Clean uses a biological treatment process with fewer mechanical components, simplifying the system and reducing maintenance needs. The Klargester Biodisc relies on rotating biological contactor (RBC) technology, which, while effective, involves more moving parts, increasing the likelihood of wear and tear over time.

When it comes to treatment performance, the One2Clean stands out with superior results across key metrics:

  • BOD (Biological Oxygen Demand): 7 mg/l
  • SS (Suspended Solids): 14 mg/l
  • NH4-N (Ammonium): 0.5 mg/l

The Biodisc, while still effective, shows slightly less impressive treatment results:

  • BOD (Biological Oxygen Demand): 10 mg/l
  • SS (Suspended Solids): 15 mg/l
  • NH4-N (Ammonium): 3.8 mg/l

The lower BOD and ammonium levels of the One2Clean indicate a more efficient breakdown of organic material and superior nutrient removal, making it an excellent choice for properties where high effluent quality is essential. The Biodisc still offers reliable treatment, but it may not achieve the same level of performance in environments requiring the absolute best in effluent purification.

Verdict: From a pure performance standpoint, the One2Clean delivers higher-quality effluent with better BOD and ammonium reduction. This makes it a strong candidate for homeowners that prioritise the highest possible water quality in their discharge or need to meet stringent effluent quality results. However, the Biodisc remains a dependable option, especially in scenarios where slightly higher levels of BOD and ammonium are acceptable.

Installation & Maintenance

One of the standout features of the One2Clean system is its easy installation process. With fewer moving parts, it requires less maintenance than many traditional systems, meaning lower long-term costs. For a homeowner, this translates into fewer service calls and reduced operational expenses.

On the other hand, the Klargester Biodisc requires a more involved installation due to its mechanical components. Regular maintenance checks are necessary to ensure that the rotating discs continue to function correctly, which may result in higher service costs over time. As there are mechanical parts inside the tank these suffer from wear & tear which are expensive to purchase and replace. Plus access into the tank is hard with a lot of equipment in the tank it can be difficult to access and maintain other parts of the tank.

Verdict: If ease of installation and low maintenance are high on your list, the One2Clean offers clear advantages. For those willing to invest more in maintenance for a robust system, the Biodisc remains a solid choice.

Energy Efficiency

The One2Clean is designed with energy efficiency in mind. Its streamlined biological process reduces energy consumption, which is a major plus for eco-conscious consumers and those looking to reduce long-term operational costs.

The Biodisc, while effective, tends to consume more energy, particularly in larger models, due to the mechanical nature of its rotating discs. This could translate into higher electricity bills over time.

Verdict: The One2Clean wins in energy efficiency, making it a better option for those focused on reducing their environmental impact and saving on energy costs.

Noise Levels

The GRAF UK One2Clean runs quietly, thanks to its limited number of moving parts. This makes it a great option for residential properties where noise could be a concern.

In comparison, the Klargester Biodisc can be noisier due to the operation of its rotating discs. While this may not be a significant issue in all situations, it could be a consideration for those looking for a more discreet system.

Verdict: The One2Clean takes the lead in terms of quieter operation, making it more suitable for noise-sensitive environments.

Cost

When comparing costs, the One2Clean generally comes out as the more affordable option, both in terms of upfront costs and long-term operational expenses. Its lower maintenance requirements and energy efficiency contribute to its cost-effectiveness.

The Klargester Biodisc, on the other hand, typically has higher upfront costs and requires more regular maintenance, which can add up over time. However, its robust construction and established technology may justify the investment for some users.

Verdict: If budget is a major consideration, the One2Clean offers a more economical solution. However, for those willing to invest in a premium product with a long-standing reputation, the Biodisc could still be worth the cost.

Conclusion

Both the GRAF UK One2Clean and the Klargester Biodisc are excellent sewage treatment solutions, but they cater to slightly different needs. If you prioritise ease of use, lower operational costs, and quiet operation, the One2Clean is the ideal choice. For those who value tried-and-tested technology and are willing to invest in a more maintenance-intensive system, the Klargester Biodisc remains a top contender.

Ultimately, the decision will come down to your specific circumstances, including budget, installation environment, and long-term goals.
