Diamond DMS Range – 1 to 20 persons

The Diamond DMS range is specifically designed for single or small groups of domestic properties situated away from wastewater mains drainage. Comprising of four models, the Diamond can treat from 1 to a maximum of 20 persons. The Diamond is CE marked and is certified to EN12566-3 2005, the new European standard covering wastewater treatment plants, making it fully compliant with UK Building Regulations.

Utilising a unique design, each purposely sized plant offers high quality, discreet wastewater treatment whilst ensuring value for money, low ongoing running costs and complete peace of mind. Typical installations include single houses, small groups of properties, flats and commercial offices.

Benefits

Process Performance

The Diamond is designed to “clean” the wastewater to a standard of 20mg/l Biological Oxygen Demand (BOD) and 30mg/l Suspended Solids (SS) on a 95 percentile basis. Additional filtration equipment is available to extend the treatment process to meet standards as high as 10mg/l BOD and 15 mg/l SS. More stringent environmental requirements involving ammonia and phosphorous reduction can also be accommodated, please contact WPL for details.
