Wastewater treatment plant sludge recovery system
Based on patent – P202030006 granted on 20-10-2020
System for the valorisation by dehydration of organic waste or malodorous products, without the emission of odours, vapours or greenhouse gases.
Sources of wastewater:
- Domestic: Urban and rural dwellings
- Hotels and residences
- Social centres
- Recreational centres
- Hospitals
- Livestock
- Agricultural
- Industrial
all purification activities are based on:
- the separation of the water for its use and
- the elimination of the solid part by biological reactions and filtrations.
The waste from the purification process is called sludge
Study area – initial zoning
The study area is identified with the municipalities of: LA OLIVA, Puerto del Rosario, ANTIGUA, BETANCURIA, TUINEJE and PÁJARA.

Current situation of the treatment of sewage sludge:
- Damage to fish fauna and eutrophication.
- Pollution of spring water and wells
- Environmental pollution due to stinking smells
- Bad image of the activity
- Bad image of the promoters
- Possible risks of spreading diseases and pests
- Loss of nutrients through degradation
- Emission of Greenhouse Gases, GHG, CH4, CO2, NH3 etc.
Future situation of sewage sludge treatment:
- Improvement of sewage treatment conditions
- Production of clean water for crops and nature
- Elimination of ponds and emissions of stinking odours
- Elimination of pathogenic micro-organisms
- Preservation of beneficial insects and worms
- No consumption of fossil fuels
- Elimination of GHG greenhouse gases
- Recovery of water from dehydration
- Manufacture of sterilised organic fertilisers
- Manufacture of patented hydrogen ways2h.com/
- Job creation
production of sewage sludge from the island of Fuerteventura:
Total sludge production of the island 5.721 m3/year
Surface of the island 1.660 km2
Population 119.732 inhabitants
Inhabitant per tourism approx. 12 %.
Annual incidence per inhabitant 0,65 m3/inhabitant
Incidence on the surface 3,45 m3/km2
Sludge composition
Water 80%
Solids 20%
Sewage sludge movement system:
Sludge is loaded into trucks to transport chain containers daily by dumping from the sludge separation systems.
Truck transporting "chain containers".
Chain container with top closure for sludge draining with 80 % moisture content.
Dewatering and conditioning
Sludge will be received, analysed, sorted and treated in treatment plants strategically located to minimise transport.
Sewage sludge with 80 % moisture.
INLET
