EFS Bioremedia DOO · Subotica
Water revitalization
and sludge management
We combine natural biological processes with precision mechanization and digital monitoring. Our goal: bring the water body back to a state where it can regulate itself — with minimal but continuous expert support. We start with a free online consultation; precise quotes only after the on-site survey.
01 · Why us
Three things we do differently
- 01
Minimal downtime
We apply biological treatment in situ — no need to drain the lake, stop the plant, or interrupt fish farming. When mechanical sludge removal is required, our parent company has its own park of automated floating dredgers designed for shallow waters.
- 02
Assessment, not guesswork
After a free online consultation and a detailed on-site survey we hand over fixed quotes for every available alternative — biological treatment, dredging, geotextile dewatering and combinations. No empty promises, no hidden costs.
- 03
Measurable results
Guaranteed sludge reduction averaging 40–60% over five years, precision dredging procedures. We've learned to clearly demonstrate the effects of the techniques we apply — when needed, we can see below the water surface.
02 · Services
What we treat
01.01 Lakes and aquaculture
Fish farms, municipal lakes, recreational lakes. We reduce organic load, eutrophication and cyanobacteria — without halting production.

01.02 Protected areas
National parks, angling lakes, Natura 2000 / Emerald sites. Habitat restoration, biodiversity, long-term water quality stability.
Learn more
02.01 Agricultural and industrial settling basins
Slurry lagoons, slaughterhouse and food-industry settling tanks, technological basins. Volume reduction, odour elimination, regulatory compliance.
Learn more
02.02 Sewers and collection networks
Biological deodorization of municipal and industrial sewers, breakdown of deposits, restoration of flow capacity. Minimal maintenance shutdown.
Learn more
03.01 Dredging and sludge removal
We extract sludge from the bed using small self-propelled machinery, large dredgers, or — when the situation calls for it — automated floating dredgers. With on-site dewatering and safe disposal.
Learn more
03.02 Geotextile structures
Sludge dewatering pads, geotextile tubes, shoreline protection sleeves and drainage structures. In-house sewing facility, custom production in Hungary.

03.03 LakeMind Club — AI monitoring membership
Continuous water quality monitoring on a membership basis: smart buoys, real-time dashboard, automated reports, 7-day algae bloom forecasting.

How we work — in four steps
- 01
Step 01
Contact
You send us the basic data and materials about your water body or system. We use them to prepare for the online consultation.
- 02
Step 02
Online consultation
A free video meeting: we clarify your goals, deadlines and regulatory obligations. We provide a cost estimate and a fixed price for the detailed on-site survey.
- 03
Step 03
On-site survey
On your order: we visit the location, perform measurements and sampling, build a knowledge base and hand over priced maintenance concepts.
- 04
Step 04
Implementation
On your order we carry out the agreed works — biological treatment, dredging, geotextile dewatering, or a combination — and do everything to reach the agreed goals.

From our work
04 · Palić
Everything we can — for Palić
Lake Palić is our home — Subotica is the headquarters of EFS Bioremedia DOO. For decades we have watched this shallow, saline lake struggle with eutrophication, the decline of natural water replenishment, and the consequences of climate change.
Our company — together with our parent Iszapfaló Kft. — invests its own time, expertise and resources in research and the preparation of solutions for Palić. We cooperate with relevant institutions, participate in professional consultations, and develop a methodology that could restore the lake's ecological balance.
Our commitment to Palić is not a marketing gesture — it is our duty to the local community and to our profession.
