What utilities arrangements are required?
An electric supply with earthing and water.
An electric supply with earthing and water.
Our service personnel will conduct a site visit to freeze location of the digester, gas storage and stove. Availability of utilities will also be checked and the client will be informed of any modifications to be carried out. The date and time of installation will be scheduled.
During installation, the digester will be fitted and charged with starter bacteria and left for a week to 10 days for the bacteria to multiply. Another visit is conducted to check the quality of gas produced. After which you may start feeding the digester following the Start-up Feed Schedule.
It is very important to follow the feed schedule to ensure bacteria multiply and do their job. Overfeeding will disturb the process and a complete restart may be needed.
Yes! Dedko has evolved so that it can live on your balcony or utility area. All that is required is the necessary space.
Certainly! We can ship you a kit provide instructions and remote support.
The digesters may get “indigestion” and may stop the production of bio gas and organic fertilizer. Call for service. The service personnel may need to flush the digester and recharge it with an active culture of bacteria.
Please follow instructions, these are living organisms that need time to grow.
Feed as per rated . Crush the feed along with water in the feed station.
Care must be taken to ensure plastic an highly fibrous material does not get in. This will choke up the crusher and piping.
A disciplined approach to waste segregation goes a long way in ensuring trouble free operation.
Yes. Just ensure that total feed in 24 hrs is within the rated capacity.
Under normal conditions cleaning and an oil change is all that is needed.
A partial drain may be required approximately once in 5 years. In addition the crusher and compressor will require an overhaul every 5 years.
No. The systems comes along with its specially designed stove. Commercial LPG or propane stoves will not work and need to be modified by trained personnel.
The systems have been designed to store about 1 days gas generation.
If the generated gas is not consumed, there is a mechanism to safely vent it automatically.
However, as the process involves combustion, care and common sense must be observed. Safety precautions to be adhered to such as : any leaks if detected, must be attended to, smoking should NOT be carried out in the vicinity of Dedko, etc.
In general, bio-gas is considered to be much safer than a traditional LPG or CNG use.
All kinds of wet natural items such as vegetables and their peals, human food scraps, milk, meat, eggs, grains, etc. It may be easier to look at what is NOT suitable. Small pieces occationally will not affect the systems.
About 10% of the feed weight. Higher quantities of gas will be generated from high calorie feed such as grains and less from leaves.
The fuel gas generated is commonly referred to as bio-gas. Its composition is about 70% methane with the balance being carbon dioxide. Traces of moisture and Hydrogen Sulphide are present.
The gas when burned in the stove is practically odorless. The good news is that if it leaks, unburned, it will be readily detected by a human; the smell is that of rotten eggs and very unpleasant. Any leakage must be attended to.
No. There is no smell from the digesters. They are completely sealed.
The organic fertilizer generated has an mild odor for cow dung.
Pests are not attracted to the digesters are they are completely sealed.
Each digester has a rated capacity. In no condition may the digesters be fed beyond this capacity. There is a chance of the process being upset and a time consuming and expensive restart may be required.
During the first month of operation, a gradual ramp up to the rated capacity is needed. A feed schedule will be provided by the personnel and must be adhered to.
Our digesters will be fine without feed for about 20 days.
When you restart feeding. Gradually ramp up feed over 4 days as was done during start-up. It will be typically 2 – 3 days before you start seeing any gas being generated. Be patient.
Yes. All our systems will be fine outdoors as long as they are protected from rain and direct sunlight. A shed works great.
Sometimes we’ve had to protect the systems from being tampered by monkeys!
Wiping with a damp rag is normally sufficient. Use water and mild soap if desired.
