Diamond DMC7 Sewage Treatment Plant 21-35PE

The Diamond DMC range of sewage treatment plants caters for properties housing from 21 up to 55 people. Typical uses include domestic homes, small rural communities and small commercial businesses such as industrial units, campsites and country estates. The standard tank models come supplied with a blower housed in a weatherproof kiosk and a separate small consumer unit.

The patented Diamond design not only gives you high quality process, but also provides you with a discreet, efficient and cost effective solution for the longevity of the plant.

The DMC7 is suitable for properties housing 21 to 35 persons with a tank capacity of 9056 L. See other capacities here.

Key Features

• Longer emptying cycles (up to 3 years desludge) - due to the highly efficient aeration process which breaks down organic matter at a reduced sludge growth rate.

• No internal electrical or mechanical moving parts

• Handles Seasonal Fluctuations - Efficient performance even at just 10% capacity — perfect for sites with variable occupancy or future growth in mind.

• Fully tested, accredited and certified - under European Standard BS EN12566-3 2014 approval which allows a CE mark.

• Meets consent standards - of 20mg/l BOD; 30mg/l SS; 20mg/l NH4 as a minimum.

• Part H2 UK - of building regulations.

• Designed using the British Water Code of Practice Flows and Loads - to ensure that the tank is correctly sized.

• Additional published test results:* - total ‘P’ mean average removal 52%, mean concentration 3.8mg/l - total ‘N’ mean average removal 52.2%, mean concentration 25mg/l

• Odourless plant

• Flushest lids to the ground - creating perfect integration in to the landscape.

• Compact in design - keeps the excavation to a minimum and installation simple.

• Range of invert depths - for complicated sites, allowing more discharge options

Operating Principle

1. The wastewater flows into the main tank and enters directly into the bio-chamber. The bio-chamber is a zone where the solids circulate continuously; this is achieved by air rather than mechanical or electrical parts inside the tank.

2. The draft tube enables the solids to be drawn back up into the central aeration chamber and re-circulated through the treatment process.

3. The treated liquid then exits through the dip pipe and is discharged safely in to the environment, meeting the required consent standard.
