WPL Diamond DMS

Sewage treatment plant for 
1 - 20 people

The WPL Diamond range offers sewage treatment plants for properties that are not connected to mains drainage.  The DMS range includes a range of sizes suitable for 1-20 people.

Why Diamond?

There are several key reasons to choose a Diamond wastewater solution for your development:

• Minimal maintenance, low running cost - unlike other sewage treatment plants on the market, the Diamond’s unique design has no internal moving parts.  This means that it requires minimal annual maintenance, making it economical to run.
• Kind to the environment – the Diamond’s treatment process requires no chemicals, so it’s kind to the environment.
• Minimal visual impact – the Diamond’s tank is buried entirely underground, so it has minimal visual impact.
• No smells – most other treatment plants have primary tanks which store settled solids and can emit odours.  The Diamond has no primary tank and is therefore odour-free.
• Long emptying cycle – the Diamond’s continuous bacterial digestion treats wastewater to a standard that meets all normal Environment Agency consents.  This treatment process can achieve a de-sludge (emptying) period of up to three years – much longer than that of most other plants.
  

Process Performance Guaranteed

The Diamond treats wastewater to a 95 percentile standard of:

• 20mg/l Biological Oxygen Demand (BOD)
• 30mg/l Suspended Solids (SS)
• 20mg/l Ammoniacal Nitrogen (AMM-N)

How does the Diamond treatment plant work?

• Wastewater enters the Diamond via the inlet pipe directly into the central aeration chamber (1)
• The central aeration chamber (1) empties into the bottom of the outer clarifier chamber (2).
• A drop pipe (7) releases air through a disc plate diffuser (4).
• An upward flow of process fluid draws settled solids (5) through the draft tube (3) to discharge at the surface of the aeration chamber.
• The design of the draft tube (3) ensures complete mixing of oxygen with the sewage. Oxygenation allows aerobic organisms, that biologically degrade wastewater contaminants, to grow.
• Gravity causes aerated solids to settle at the tank bottom (5) where they are drawn back up through the draft tube (3).
• Raw sewage displaces biological solids (8)from the aeration chamber (1) to the clarifier chamber (2). Quiescent conditions in the clarifier allow digested solids to settle at the base (5) and  return to the aeration chamber (1).
• The clarified effluent flows up through the scum baffle (9) and over the weir arrangement (6) prior to discharge via the outlet pipe.
