QUALITY MATTERS

light like plastic, strong like steel

Nassar Techno Group (NTG) is a global group that builds and distributes the innovative NDG line of wastewater modular plants for the biological treatment of domestic wastewaters: 6 to 1350 EH (Inhabitant Equivalent).

NTG, is a performing team with a recognized know-how who convoys its network of international and regional distributors in order to serve a large range of clients (residential, architects, project designers, municipalities, industries etc.) for the installment of wastewater treatment plants.

Via its distributors, NTG develops a performant commercial and logistic global service together with responsive local technical support.

The NDG line is compliant with the highest and most stringent quality criteria. Since 2013, NTG enjoys four French Ministry agreements in order to market its products*. The certifications comply with the best environmental requirements: ISO 9001, CE, NF, German DIN, French Ministry of Ecology, of Development, of Transport and of Habitat.

Designed and tested through cutting-edge / lengthy R&D, the innovative NDG products are specially rotomolded in one tank and are made of 2 layers of PE around one layer of foam which make them light, waterproof and resistant. They are meant for any domestic situation (underground, above ground, in phreatic pound, on site etc.)

*The characteristics which make its originality are certified by official international bodies (Vertical resistance: 16T, Lateral resistance: 10 times the norm, Waterproofing: zero leak).

FAQ – Waste Water Treatment Plants – How it works: the treatment happens in three stages: 1. Primary decantation 2. Biological reaction 3. Clarification. All our plants use the fixed immersed and aerated bed technology, the biofilm. The bacteria which are naturally present in the grey waters, constitute the biofilm by taking over its particularly porous holder, the biobloc. The biofilm reacts to the nutriments present in the water by augmenting or diminishing its layer thickness. Under full charge or surcharge, the biofilm will always have space to develop efficaciously. But when undercharge, the biofilm will get thinner yet will still degrade the grey waters efficaciously (autoregulation). Even if one suppresses completely the charge for a given period, the bacteria within the biofilm will not disappear but instead will remain embedded and hold until they have a new charge so they treat the waters immediately after. Therefore, you can leave for vacation without worrying whether your plant will remain functional for it will.
