IRIS Background

local need for reliable irrigation water,

Irrigation uses 68% of water resource Spain,

3,8 million hectares Spain,

3.600 wastewater plants small communities

Cost reduction on water.

IRIS Objectives

Small scale purification domestic

wastewater

Reclaim water and nutrients (P / N)

Application area

– Greenhouse irrigation

– Open field substrate

– Open field

IRIS challenges

Removing selectively substances from water like Na, Ca.

Nutrients: N and P in reclaimed water are beneficial to plants but

may cause nutrient imbalances, eutrophication of surface waters,

and contamination of groundwater.

Pharmaceutically-active Chemicals and Endocrine Disruptors:

Potential for eco-toxicological

pH: Affects metal solubility and alkalinity of soils.

Biodegradable Organics: BOD, COD or TOC - can cause

aesthetic and nuisance problems, adversely affect disinfection

processes, and deplete soil oxygen

IRIS Total project overview

IRIS: Intelligent

Different types of water

1: Irrigators community water

2: Effluent WWTP

3: IRIS water

Fertilizer & water dosing controlled

on needs of the plants

IRIS: Reclaim

RAW water WWTP

First step: Electro flocculation

Second step: Ultra filtration

Third step: Nano-filtration

Additional test: biogas generation

of produced sludge

Nutrients such as P and N are monitored,

in the IRIS water less nutrients are added

IRIS Process

IRIS: Irrigation

This year tomato plants on:

1: Coconut Fiber Substrate

2: Rockwool Substrate

Automatic drip system serving water to the plant.

The plant will be monitored over fruit delivery,

photosynthesis, growth etc.

IRIS: System

Project objectives:

1: Reuse of water and nutrients.

2: Optimize agronomic production.

3: Wastewater-treatment small clusters.

4: Getting marketable product ©
