Wastewater

Effective wastewater treatment plants are vital for communities and industries around the world. They also face tight operating budgets and are constantly looking for ways to improve efficiency. Chemicals can bring substantial energy-savings in the wastewater treatment process. Using coagulants in addition to or instead of biological methods can save up to 50% of aeration energy in organic (BOD) removal, and can double biogas production. Our unique, broad range of water treatment expertise and products offers solutions to all wastewater challenges.

There are numerous sources of odor in wastewater systems. Knowing the dominant source of the nuisance is essential for the correct mitigation approach. In most cases, problems are caused by hydrogen sulfide, H₂S. Mineral scale, such as struvite, vivianite and calcite, can cause expensive and difficult problems like clogged pipes and heat exchangers, as well as damaged pumps, sensors and valves. Foam can be a problem in many water treatment applications as well as in various production processes.

Kemira offering tackles all these challenges. Optimization and cost-savings without jeopardizing safety is a key component for our solutions that combine chemistry expertise and real-time monitoring and optimization. Understanding the complete system is critical for providing a successful solution.

It is important that sludge volumes are kept at a minimum with a high dry-solids content to reduce disposal costs. Our customers report success cases in sludge dewatering where we have significantly increased dry solids. This gives direct benefits not only in reduced costs, but also by increasing the dewatering unit capacity at the same polymer dosage. In addition, odor control, mainly hydrogen sulfide and ammonia emissions, can be improved and cleanouts due to struvite reduced.

Partnering with us offers you a full range of organic and inorganic coagulants and polymers, combined with monitoring and optimizing solutions and extensive application knowhow. Our approach to enhanced sludge dewatering includes technologies for smart process management and enables the optimization of chemical consumption, always delivering the best dewatering performance.

More and more industries are starting to run anaerobic digesters to capture the full energy potential of their organic waste. Producing biogas from organic sludge is a viable way to reduce energy costs. We can help you in boosting your biogas production capability.
