[...]Reliable pre-treatment for septic sludge Wherever wastewater is not fed to a sewage treatment plant via the sewer system, but is treated decentrally, septic sludge is produced. This septic sludge collects either in simple septic tanks or in more modern small wastewater treatment plants and must be removed at regular intervals to be treated in a central plant. Where possible, this is done at a centralized wastewater treatment plant with sufficient surplus capacity; but where such a plant is not available nearby, a separate onsite plant for the complete treatment of septic sludge can also be built. Septic[...]

[...]Ingolstadt, Germany Two HUBER belt dryers BT were put into operation on STP Ingolstadt in August 2005. The installed total dryer surface is 160 m² which is the same as that of our new dryer type BT 16.

[...]Products and solutions for the safe operation of sewer systems and the protection of our environment Only with a functioning sewer network can secure wastewater disposal be ensured that meets both water protection and flood protection requirements. Combined sewers carry the wastewater together with the rainwater that accumulates on paved surfaces (roofs, roads, etc.). In a separate sewer system, wastewater and stormwater are collected separately. The disadvantage of separate sewer systems is higher investment costs, the advantage is that less wastewater has to be treated in the sewage treatment[...]

[...]Combined Sewerage and Stormwater Treatment Protection of water bodies from polluted rainwater The advanced treatment of combined and stormwater in wastewater transportation systems is a main issue with regard to sustainable environmental and water protection. The building of new wastewater treatment plants and the upgrading or refurbishing continuous wastewater discharges has significantly increased the quality of many watercourses. Nevertheless, despite all efforts, ecological deficits still exist. Some of the problems are caused in the discharges of combined and separated sewers during storm [...]
