Our commitment
to healthy water.

When it comes to natural bodies of water, bathing lakes, fish farms or water obstacles on golf courses, it's often difficult to maintain the water quality and keep it balanced and healthy. Our references show just how varied the effects of this problem can be and how bodies of water can be brought back into balance using natural and sustainable means. We call this "helping nature help itself".

Special Area of Conservation
Mühlenteich

More frequent periods of drought and sediment build-up were causing the water level of the pond in the nature reserve to sink steadily. This led to a huge number of fish dying for several years in a row. The long-term use of SchlixX plus from 2012 onwards made it possible to stop siltation and fish mortality while maintaining the valuable biotope. The environmental compatibility of the water therapy was documented through intensive monitoring by experts over an eight-year period. 

Key facts

  • Location: Georgsmarienhütte, Lower Saxony
  • Pond in a conservation area; 10,700 m2
  • Problem: Siltation, sludge accumulation, oxygen depletion, fish death
  • Result: Sludge reduced by 34% on average from 2013 to 2020. Fish mortality stopped despite new siltation of around 3 cm each year 
     

Lake for bathing and recreation 
Kleiner Russweiher

At Bavaria's largest lakefront mud bath spa, foul-smelling sludge and mud has increasingly become a problem for bathers, anglers and nearby tourism. For this reason, a collaborative water therapy project involving the spa operators, tenants and municipal representatives was launched in 2019 that has provided very convincing results.

Key facts

  • Location: Eschenbach, Bavaria, Germany
  • Lake for bathing and recreation, 27 ha
  • Problem: Sludge formation, silting
  • Result: 28,000 m3 of organic sludge removed, sediment reduced by an average of 22 cm
     

Schwanenweiher pond, Landau (Palatinate) 

If a body of water in a municipal park is threatened with becoming a dead zone, local politics and administration must act quickly – not least due to significant pressure from the public. To combat this issue, the town of Landau in the Palatinate region made use of the innovate solution SchlixX Plus, along with PeriDox to quickly prevent an incipient fish die-off.   

Keyfacts

  • Location: Landau (Palatinate) 
  • Pond in park, about 1 hectare 
  • Problem: Foul odour, oxygen depletion, sludge formation, fish die-off 
  • Result: Odour reduction, sludge reduction, increase in oxygen content, fish die-off prevented 
     

Natural body of water Quellitzsee

The popularity of Quellitzsee lake as a recreational area for swimmers and anglers was severely affected by major sludge formation and blue algae. By using the environmentally friendly SchlixX Plus, OASE was able to achieve a sludge reduction of 50–75% and restore full use of the water.

Key facts

  • Location: Tauperlitz, Bavaria, Germany
  • Natural body of water, 6 ha
  • Problem: Sludge formation, silting, blue algae growth
  • Result: 50–75% sludge reduction
     

Fish farm pond Rödental

This fish farm in Rödental, Upper Franconia manages six carp ponds. The problem: Heavy sludge formation and too little oxygen led to a huge number of carp deaths. The OASE solution: Using SchlixX Plus, winner of the German Award for Sustainability, to reduce sludge, and PeriDox, which has been developed to keep fish healthy. 

Key facts

  • Location: Rödental, Bavaria, Germany
  • Fish farm pond, 4000 m3
  • Problem: Lack of oxygen, sludge formation, fish death
  • Result: Sludge reduction, increase in oxygen content, fish death prevented
