How to Use Moringa to Dewater Sludge
Dewatering sewage sludge with Moringa oleifera is a safe, effective and easy process. It is also sustainable and good for the environment. Moringa is a very resilient species of tree which grows under very harsh conditions. It draws up water into its thick root and stem and produces an abundance of fruit that are edible as a vegetable. It is easy to grow and requires little cultivation. Dewatering sludge with Moringa is feasible on a large or small scale. Does this Spark an idea?
Things You'll Need
- Area of land
- Mechanical excavator
- 25 tons sludge
- Mobile sludge tanker
- 100 moringa oleifera seeds
- Measuring tape
- Spade
- Watering can
- 2 gallons water
- 4 marking pegs
Instructions
-
Marking Out of Dewatering Area
-
1
Measure a rectangular area of land 15 feet by 30 feet using the measuring tape. Mark the corners with the marking pegs.
-
2
Using the mechanical excavator, dig the soil out of the dewatering area to a depth of 18 inches.
-
-
3
Using the mechanical excavator, place the soil on the edge of the rectangular area to create a raised lip.
Planting and Growing the Moringa Oleifera Trees
-
4
A spade is needed to plant the seeds. Using the spade, dig a hole four inches deep.
-
5
Place two seeds in the hole and cover with soil.
-
6
A stong watering can is required to transport water to the planting area. Fill the watering can with water. Water the area where the seeds have been planted.
-
7
Dig more holes three feet apart and plant the remainder of the seeds over the dewatering area. Water them all.
-
8
Wait for the trees to grow to three feet. This will take around three months, depending on the soil and growing conditions.
Fill Dewatering Area With Sludge to be Dewatered
-
9
A sludge tanker is required to transport sludge safely. Fill the mobile sludge tanker with sludge and drive to the dewatering area.
-
10
Pump the sludge into the dewatering area, ensuring even coverage and depth. Depth should not exceed 10 inches.
-
11
When the level of the sludge drops in the dewatering area, refill it.

Tips & Warnings
When the sludge has been sufficiently dewatered, more can be added to the treatment area. Moringa will not grow in cold or temperate climates.
Sludge can be toxic and care must be taken when working with or around it.
Do not overfill the treatment area above the prescribed level.

Both I and the wife have found Moringa to be very tastey and growing very fast in our desert here in California, very attractive plant as well.
