SBR-process (Sequencing-Batch-Reactor) is the combination of the procedural functions “Aeration” and “Clarification” in one reaction tank. Here from a stable and flexible process flow results. Furthermore the SBR-process enables a compact plant design and a minimization of the investment costs. Because of the flexible plant geometry (tanks with circular, quadratic or rectangular footprint) SBR-wastewater treatment plants of w-wwt can be simply realized also under hindered project conditions (tourism areas, recreation centers, tower buildings etc.).

Nell'articolo, estratto dal numero di novembre 2015 della rivista "Ecoscienza - Sostenibilità e controllo ambientale" di Arpa Emilia Romagna, l'ing. Anna Moretto dell'Ente di bacino Padova 2 affronta e approfondisce il tema dell'applicazione della tariffa di smaltimento dei rifiuti urbani nella regione Veneto.
STUDIO DELLA QUALITA’ DELL’ ACQUA NELLA SACCA DEGLI SCARDOVARI E ANALISI LCA ...ente di bacino padova 2
Integrazione delle analisi delle acque svolta in precedenza, sotto diversi aspetti ambientali, ed esame degli allevamenti di cozze e D.O.P. presenti nella Sacca e zone adiacenti.
Analisi con metodologia Life Cyicle Assessment (LCA) di come questo prodotto incide sull'ambiente.
Non tutti i materiali per essere recuperati devono essere forzatamente condotti a speciali impianti di riciclaggio. Infatti la raccolta differenziata si può effettuare direttamente da casa con il compostaggio domestico dei rifiuti organici svolto da chi ha un giardino nella propria casa di residenza. Circa il 25-30% dei rifiuti delle famiglie è infatti composto da rifiuti organici come scarti di cibo o frutta, piante recise, sfalci dei prati, fogliame, erbacce, trucioli ecc.
Così come la natura scompone e reintegra nell’ambiente foglie morte e frutti caduti, anche l’essere umano può imitare un processo così semplice e comprensibile evitando lo spreco di risorse, riciclando e reintegrando gli scarti della tua cucina nella natura, convertendoli in concime

• Capping with 30 cm of clay material + 80 cm of soil
mixed
• Average yield of leachate of about 7600 m3/year
• Leachate collection wells with pneumatic suction
pumps
• storage in several leachate tanks and sent to waste
water treatment plant with tankers (1-2 trips / week)
6. The solar still
Solar stills use in the treatment of solutions containing water,
advantages:
•the absence of external sources of supply;
•low maintenance;
•ease of management, without the need for trained personnel;
•reduced cost and limited to the initial investment.
7. SOLWA (SOLar Water)
The advantages of solar still SOLWA to the treatment of landfill leachate:
•Continuous flow operation;
•Maintenance close to zero;
•Air recirculation with lack of external odor;
•Increased capacity of treatment;
•Extraction of 50% of the initial water from the leachate.
8. The project: solar still plant
AIM:
•In-situ leachate treatment
(DGR 264/13)
•Extract the water and
discharge into surface water
bodies
•Using solutions of high

11. Conclusions:
The chemical analysis carried out show that the solar stills are capable of extracting an
aqueous solution containing ammonia (NH 4) with high concentrations (853 mg / liter)
The change in the system with solar stills allows to:
1.Halving the volume to be treated, concentrating the ammonia in 50% of water extracted;
2.Ability to extract pure ammonium salts for commercial use (agricultural use);
It appears that the solar stills are able to concentrate the leachate at least 50%, balancing
the ratio C / N = 10
1. Possibility of realizing a conctructed wetland system capable of blocking the various
pollutants;
2. Discharge into surface water body without using any chemical compound or complex
plant.
12. Conclusions:
The SOLWA solar stills have demonstrated, for the first time, as the
technology of solar still is applicable to the treatment of landfill leachate,
with the following advantages observed:
1.no emission of odour or other volatile compounds in the atmosphere;
2.good capacity for removal of water from the leachate;
3.use of renewable energy sources;
4.possibility of application of the system on site (landfill);
5.low maintenance and operational specialization;
6.reducing the cost of handling, transportation and disposal of leachate;
7.project highly eco-friendly.
