💦 Different tank for a change 💦
Not our usual potable water tank going in this time. At a local estate.
Due to the poor condition of the current septic tank along with constant blackages our client decided it was time for change.
After a site meeting to discuss potential options. It was decided to upgrade the whole waste water system including a new 7 person One 2 clean Graf waste water treatment plant.
How a GRAF wastewater treatment plant works
The GRAF systems use SBR (Sequencing Batch Reactor) technology:
💧Wastewater enters the treatment tank.
💧Aeration supplies oxygen, allowing microorganisms to break down organic pollutants.
💧During the settling phase, solids sink to the bottom.
💧Treated water is discharged, and the cycle repeats.
Key features
💧Low energy consumption (as low as about 0.63 kWh/day for some models).
💧High effluent quality that meets UK environmental standards.
💧Quiet operation (around 36 dB).
💧Available for small domestic installations and larger commercial developments.
