مُساهمةموضوع: Bio waste Treatment Technology    الخميس أبريل 19, 2012 3:05 pm

Organic wastes should be reused in the environment in a safe and economical manner. Cambi's solution is based on a heat treatment of the waste, without the addition of air (anaerobe process), so that the most easily degradable substances dissolve in water. The liquid phase is used for the production of biogas or as a carbon source for a biological wastewater treatment plant. Alternatively, the entire waste mass can go through a digestion process after hydrolysis in order to produce a maximum amount of biogas prior to dewatering and post-treatment of the compost.

The process has several benefits:
• flexibility with respect to waste composition
• recycling of resources
• compact and closed process with good odor control
• can be built in stages
Altogether, it offers an environmentally sound and profitable approach to waste treatment.
Flexibility with respect to the composition of the waste
Organic waste often consists of the following main elements:
• food waste
• garden and park waste
• nappies/diapers
• polluted/wet paper
• other waste, including stones, glass, plastic, etc.
The distribution of these items in the waste will depend on the collection method, demographic structure and time of year. For Cambi 's technological development, the key has been to be able to treat the widest possible range of waste because:
1. The more waste away from the landfill, the better.
2. Mistakes in sorting are inevitable, and should not cause operating failures.
Recycling resources
The soluble material from the hydrolysis process can be used either directly as a carbon source in a biological waste water treatment plant or for the production of biogas in a digester. The biogas is burned in a steam boiler and produces the necessary heat for the plant. The amount of gas can be increased by combining it with a landfill gas facility and/or by allowing the entire amount of waste to be digested. Biogas can also be used in gas engine for producing electricity and excess energy can be sold to the local Power Company.
The compost is of very high quality because the hydrolysis ensures good hygiene at all times of the year. In addition, glass, metal and plastic are removed effectively.
Compact and closed process with good odor control
Thirty to sixty percent of the organic material is treated (hydrolysis) for one hour without the need of any structural material. The corresponding time for breaking down the material using traditional composting methods is 2-4 weeks. This means that the plant can be built compact. Furthermore, the process is completely closed so that all resulting gases are under full control and the odor is effectively cleaned in a biological filter.
Built in stages
The plant is designed as a modular system so that the customer can choose which functions are desirable. This means that the plant can be adapted to different needs and the construction can be planned in steps.
A future expansion is therefore possible; both to handle new capacity requirements and to meet needs related to the end products.
