We are looking for suppliers of compact units for sludge / gas management on smaller WWTPs. The main interest is for digesters for anaerobic sludge stabilization. The goal is biogas production around 50-250 NCMH.
We manufacture small biodigesters......either 20ft. ISO Container mounted or 40ft. ISO Container mounted. Capacity from 6/8 tonne per week to 26/28 tonne per week. We can go as high as 200 tonne per week for industrial pants.
We also manufacture a special biological, fully organic solution that when added to the biodigester speeds up the entire process and produces extra gas.
We at NVH Global Ltd, a spin out from Univeristy of Surrey, are expert in low cost onsite solutions. We can advise you on how to build economically on site using local labour and products. We also can advsie if it makes economic sense to use the sludeg for biogas production or what to do to make economically viable. o rif not abstratc other valuable materisl for sale. Working with us would allow you to be innovative and offereing suitable solutions across the country. We are working in India and the Philippines and now also with our water untilities in the UK. We can draw on all the resources of the Chemical and Environmental Engineering capacity of the Univeristy .
Il n'existe aucune digestion des boues sans oxygène. Pourquoi? Tout simplement parce que l'état moléculaire de l'eau est H2O, DEUX molécules d'oxygène. là ou il y a de l'eau il n'y a pas d'état sans oxygène.
Idem pour la digestion. Ce terme ne veut rien dire. Toute matière organique qui sort de son processus d'élimination naturelle par la biodégradation, se transformeen boue sous l'effet de la putréfaction activé par la méthanisation du milieu.
La problèmatique de ce genre de pratique c'est qu'elle génère des déchets qui sont imposssible à déruire autrement que par la technicité ( incinération). Dispersée dans l'environnement c'est un véritable poison surtout si ces boues sont imprégnées de molécules chimiques comme c'est le cas de toutes les boues qui sortent des stations d'épuration car il n'y a aucune action préventive.

Hello there is no digestion of sludge without oxygen. What for? Simply because the molecular state of water is H2O, two molecules of oxygen. Where there is water there is no state without oxygen.
Same for digestion. That term doesn't mean anything. Any organic matter that comes out of its natural elimination process by biodegradation, is transformed into mud by the effect of decay activated by the anaerobic digestion of the medium.
The problematic of this kind of practice is that it generates waste that is failed to déruire other than by technicality (incineration). Dispersed in the environment it is a real poison especially if these sludges are impregnated with chemical molecules as is the case of all the sludge coming out of the sewage treatment plants because there is no preventive action.
Please do not mis-interpret. Water has two molecules of Hydrogen and only one oxygen and ionises as H-OH. It can hydrolyse not oxidise. Anaerobic digestion uses methanogenic bacteria in the absense of oxygen to generate biogas. Given the precise requirement / specification like waste characteristics, quantity and treatment capacity we can supply the right equipment. Contact:
