This week, the DIRECT-RO landfill leachate treatment plant started its long journey to São Gonçalo, Brazil.

Pungent odor, harmful outgassing, an almost black liquid – this is leachate from waste, which is also a serious problem in Brazil. Due to the lack of treatment capacities, highly loaded landfill leachate flows uncontrollably into the groundwater in some places and contaminates the environment.
WEHRLE has taken on the problem together with its customer Orizon, a waste treatment and recycling company from Brazil, which is also committed to the Green Transformation.
After extensive consultation and evaluation of different solutions and process combinations, the customer opted for a DIRECT-RO XL plant. The compact wastewater treatment plant can be quickly commissioned and easily operated. Depending on the requirements, the plant can be expanded to a biological treatment concept, enabling Orizon to ensure the future viability of its landfill in São Gonçalo.
In addition to the conceptual design, WEHRLE’s scope of supply includes the construction and delivery of the 3-stage containerized Reverse Osmosis (RO) plant. The on-site installation and commissioning of the plant will be carried out by WEHRLE’s long-term partner Ambiensys. Due to the compact construction and the user-friendly operation of WEHRLE plants, the customer is able to quickly acquire the necessary knowledge to manage the daily plant operation himself.
The direct Reverse Osmosis is designed for a permeate capacity of 250 m³/d. With effluent values of < 200 mg/l COD (influent before treatment 11,700 mg/l COD) and < 5 mg/l NH4-N (influent before treatment 1,965 mg/l NH4-N), the leachate treatment plant meets all the customer’s requirements for direct discharge.
The plant, which has been built in a standardized 40-foot container, will be put into operation after a delivery time of only eight weeks.
