schoonschip: phase I 3 100% wastewater & organic waste treatment agriculture. These hatches also allow for the system to be serviced when necesary. Each pier of 6 buildings (10-11 households) will have its own D-SARR system. The D-SARR system will first be piloted at the de Ceuvel site. It consists of different reactors for processing the waste and producing biogas. Sensors are included to monitor flow rates and to alert the community before something goes wrong. The system will also contain water upgrading modules; helophyte filters will be placed on the side of the jetty, purifying the water before it is finally discharged. COST & LABOR ESTIMATES We recommend using urine separating toilets, which require very little water use. The toilets separate and collect two streams of human waste, which are pumped to the DIY modular treatment system installed in the jetty (the DSARR system, described in more detail on pages 51 - 53). The graphic to the right shows how waste streams will flow from the houseboats to the jetty and reedbed filters. The D-SARR treatment system is modeled on the one used at the de Ceuvel site. There will need to be access hatches in the jetty so that different materials like purified nutrients can be harvested from the system for use in on-site The estimated per-household cost and labor estimates for installing the D-SARR system are 4.800 € and 100 hours of labor. In addition, the water upgrading system and vertical reedbed will cost an estimated 2.000 € and 55 hours of labor per houshold. Our materials costs are based on bulk purchases from Eastern Europe or Asia. If these purchases cannot be made collectively, the price of the system may increase. Labor costs are not included, with the assumption that the community will do a large part of the construction. However, with this element in particular, outside assistance from professionals may be required, which may increase the overall cost. collection humus collection struvite Schoonschip Technology Schematic agriculture on-site pump 15 W pump 15 W BASEMENT / UTILITY AREA kitchen waste pasteurizer 100 C 20 L anaerobic digester 70 C 1 m3 heat biogas boiler 2 HOUSEHOLDS - 7 PEOPLE BATHROOM diverting toilet urine urine brown water water hot KTICHEN biogas boiler cooking gas gas stripping storage 1 m3 gas JETTY sand filter 1 m x 1 m x 0,8 m UV filter flow rate - x effluent cleanish effluent humus tank 0,5 m3 struvite reactor 400 L 1 m3 biogas boiler heat digestion reactor post1 m3 effluent nitrogen removal 1 m3 biogas water discharge treatment unit reed 1 m3 treatment unit reed 1 m3 treatment unit reed 1 m3 treatment unit reed 1 m3 BESIDE JETTY Pagina 74
