Overview

Business areas

JÄRVEN ECOTECH AB

• Established on 30 years experience of creating water purification.

• The business concept of Järven Ecotech AB is to offer cost effective water purification built on our experience and patented plug and play concept. As well as understanding functional hydraulic conditions to achieve maximum purification.

• To ad extra value into water treatment.

Solutions by Järven Ecotech

• Municipality waste water treatment by FELLINGSDAM

• Lake restauration by pond in lake solution.• Leachate water and industrial waste water

treatment.

Fellingsdam

• Fellingsdam = Waste Water Treatment by chemical precipitation.

• Developed in Örnsköldsvik 30 year ago to meet local demands on improved and sustainable waste water treatment at a reasonable cost.

• Suitable for villages and smaller cities with accessible land at reasonable cost

Mid Sweden locations

FELLINGSDAM

We have extended the hydraulic

detention time from 7 hours to 7 days just by installing 2

float walls in a square pond of

10000m2

Save 80% in construction and operational costs

” Water behaves as lazy schoolchildren, it always takes the fastest route, no matter how many road signs there are. ”*

”ÄLTASJÖN”

To think about withwater purification plants in flowing water

• To be able to withstand flowing water ( >2 M/s ) a velocity absorber have to be placed upstream of the plant.

• There is a built in obstacle to prevent spawning fish to enter the plant.

OPTIMISATION OF ECOTECH PONDS

• The purification effect can be increased by steering the water through natural or planted fields of water plants.

• The water plants needs ”harvest” to maintain a high reducing effect of N and P.
