WATER TOPICQuality of natural systems 
KEYWORDSQuality of natural systems, Sludge Management. 
KEYWORDS TYPEmethodology, procedure. 
MARKET NEED TAILORED

The project concerns the reuse of waste from municipal wastewater and residue accumulated in the beds of those lakes. The services provided by the project refer to the development of experimental models by which the water quality policy and waste management is supported.

 
OUTPUT DESCRIPTION

The objective was to identify by analysis and research of biodegradable waste recovery methods such as residue reservoirs (storage pools) and sludge from urban wastewater treatment plants.

The end result of the project had two main directions: exploitation in agriculture of residue sludge from the ponds / lakes and / or urban wastewater treatment plants and / or energy recovery in biogas plants. Through the 3 stages of the research were obtained:

• 1 model of recovery type of waste sludge from sewage plants and waste from storage pools by using as a substrate for biological material such as fruit trees, corn and lettuce;

• 1 way analysis of greenhouse gas emissions from biodegradable waste in order to establish an energy recovery solution.

• 3 working procedures for the determination of physico-chemical characteristics and removal of biodegradable waste.

• 1 documentation containing input data to perform a database of different types of biodegradable waste (sludge from wastewater treatment plants, waste from storage tanks, etc.).

 
STATE OF DEVELOPMENT

Pilot at small scale

 
INNOVATIVE ASPECTS AND ADVANTAGES

The realization of complex research papers to determine the mechanism of crossing toxic compounds present in biodegradable waste (sludge from sewage plants and the storage tanks) in fruit and vegetables. The use of advanced characterization techniques (molecular and atomic absorption spectrometry, gas-chromatography, mass spectrometry) to:

  •  Dose maximum sludge fertilization;
  •  Dose maximum accumulation of heavy metals in soil;
  •  Establish the correlation between concentrations of heavy metals in soil and their presence in plants.
  • Test methods for determining the influence of fertilization with sludge on some chemical characteristics of the soil, production and chemical composition of various tissues of agricultural plants.
  • Identify types of plants compatible with substrates obtained by mixing soil with two types of waste fertilizing properties.
  • Experiment energetic recovery solutions for biodegradable waste.
 
INTELLECTUAL/INDUSTRIAL PROPERTY RIGHTS

IPR belongs to the partners. Intellectual property on technical documentation, on technical and scientific results, patents etc. lies with the coordinating contractor and partners.

 
TRANSFERABILITY

Until today the use of technology as a substrate of the 2 types of waste was tested only one of the partners (SCDP Valcea). It can also be used in crops with potential energy (biomass).

 
POTENTIAL USERS/CLIENTS
  • Urban/ municipal wastewater treatment plants
  • Administration basins:
 
 Estimation of risks
EVALUATION OF RISKS FOR OUTPUT USERS

Currently, the sludges from municipal wastewater treatment plants are not used and the drained waste from the reservoirs are deposited in the immediate vicinity thereof, without identifying a potential use them. The results obtained by these types of waste reuse involves identifying potential users located in close proximity to these sources of waste (see section anticipated customers).

ECONOMICAL RISKS? ?
TECHNICAL RISKSTechnical risks are caused by soil types (soil tested low in nutrients) of sludges (heavy metals in traced amounts, but with a high capacity of storage and stabilization), by the types of plants (shrubs with certain periods of growth).
MARKET RISKSThere has been a reluctance manifested by land users in using this type of mud.
 Steps ahead
NEXT STEPS TO ACHIEVE THE STATUS 'READY TO USE'
  • Identifying potential producers of sludge (municipal treatment plants and hydro pools)
  • Establishing types of fertilizer blending plants proposed for sale
  • Achieving a pilot plant preparation of the fertilizer mixture in view to commercialize it thereof
TYPE OF PARTNER FOR THE NEXT DEVELOPMENTS• Administration of basins and wastewater treatment plants, waste management operators, SMEs dealing with waste management.
TASKS TO BE PERFORMED

Technical assistance on soil and plant characteristics to be tested with the produced fertilizers. Achieving in partnership of a guide for fertilizer users. Industrial-scale testing of the 2 types of waste as substrates (fertilizers) for agricultural soils except those for grazing, cultivation of fruit trees, vegetables, fruit shrubs by 10 months before harvest and during harvest (according to Order 344 / 2004).

COLLABORATION DETAILS

Technical cooperation, agreement of financing.
