Promotion of our activities on the industrial field - process water treatment/chemical engineering
| BIOGAS PLANTS neuhold Nowadays civilisation is facing the problem of a higher proportional increasing of the waste amount than the growth rate of the world population. The enormous waste-amount per human life is overextending waste management capacities of bigger and smaller cities! The waste is consisting of two fractions, the organic and inorganic fraction! People already know how that the inorganic share has to be divided into glass, metal and plastics and gets recycled. The organic fraction, which must be treated immediately because of the biological degradation, so far has been treated aerobically, means composted. The main objective has been to reduce the volume of waste by demanding big areas of land, time and energy consuming treatment of the compost. The energy that is stored in the organic fraction has been wasted more or less. Also the large areas that are necessary for composting are not available in large cities anymore as they are valuable and needed for infrastructure projects |
| Flushing systems for storm water tanks and channels Flushing systems for storm water tanks and channels Extra efficient cleaning without external water supply, with or without external power. Flushing lanes in tanks up to 120 m as well as flushing lanes in channels up to 200 m have been built. Material stainless steel, the plants are nearly maintenance-free. |
| Mobile Flood Protection Walls FLOOD PROTECTION WALL - RIVER EMBANKMENT Industrial and municipal object and area protection |
| Screening plants counter current screen is an automatic bar screenm rake is working from the counter flow side and can be used as coarse or fine screen. It is especially suitable for deep and wide, rectangular channels. The screen is made of stainless steel, without moving parts below water level (except the rake during operation), with a high rake loading capacity and low head loss, guarantees a safe operation and low maintenance cost. therefore less wear and tear and low maintenance costs. Small floor requirement because of vertical installation (90°). | |
