Sustainability thanks to FlexBio wastewater treatment

Slaughterhouses and meat processing companies produce wastewater which is characterized by a high fat content, many solids and high COD and nitrogen loads. In conventional wastewater treatment plants, these entered loads result in large amounts of flotate and sewage sludge as well as a high energy requirement.

Your benefits at a glance

  • Compact and modular
  • Expandable as needed
  • Easy integration during operation (plug & play principle)
  • Elimination of heavy pollution fees
  • Low maintenance
  • Chemicals savings
  • Low operating costs
  • Sustainable biogas production
  • Improve the CO2 balance of your business

The unique FlexBio wastewater treatment converts the fats and COD loads entered into energy-rich biogas. This technology significantly reduces waste streams and you do not have to costly dispose of flotate fat. In addition, you produce up to 20% of the total energy requirements of your company directly from the wastewater.

We offer solutions for direct discharge as well as indirect discharge into the neighboring wastewater treatment plant. Thanks to our effective cleaning technology, there are no heavy pollution charges or other surcharges on the wastewater tax.

Technology in practice

The FlexBio wastewater technology effectively and inexpensively cleans the wastewater that arises in meat processing plants and slaughterhouses. Regardless of whether you slaughter and / or process chickens, pigs or cattle, wastewater treatment does its job at the highest level. The raw sewage is first passed through a separator / drum screen to separate contaminants. The wastewater is then temporarily stored in a storage tank and homogenized. In this 1st stage the hydrolysis (pre-disruption of the cells) takes place. The wastewater then goes to the main purification stage of the plant: the high-performance fermenter. Here, the fats and organic compounds entered are converted into biogas using the biological process of methanogenesis. At this stage, over 90% of the organic pollution is reduced. This does not result in any material flows that have to be disposed of.

The pre-treated wastewater is treated aerobically in the downstream 2nd treatment stage. In this stage, the remaining impurities are removed from the wastewater. Depending on the nature of the wastewater, the downstream addition of precipitants and pH buffers is also possible. In comparison to conventional wastewater treatment plants, it is added in small quantities, since a large proportion of all impurities are already removed biologically. The fats and organic matter are already broken down in the high-performance fermenter and can therefore not be converted into sludge in the aerobic system. This results in less excess sludge and, at the same time, a drastic reduction in aeration energy.

The biogas produced can be used directly in a CHP or in a thermal bath and provide sustainable energy for your company. If necessary, the biogas can also be used to produce compressed air or cold.

The system is designed for changing loads. Even strong shock loads are buffered and therefore have no influence on the discharge values . The process values can be set individually and permanently guaranteed by the intelligent process management. Regardless of whether you introduce indirectly and only have to comply with a COD limit value or whether you, as a direct discharger, have to comply with COD, BOD5, total nitrogen, nitrate, nitrite, ammonium, phosphates, lipophilic substances, etc., the system always offers the right solution.
