End-to-End Solutions: Engineering Efficiency Across the Full Lifecycle

When regulations tighten and feed water quality fluctuates, you need a partner with definitive experience in process development. Envirogen provides cradle-to-grave technology and service solutions designed to ensure lasting operational and capital efficiencies.

We focus on the total project lifecycle, ensuring that upfront phys/chem steps are seamlessly integrated with downstream advanced processes to achieve the lowest Total Expenditure (TOTEX).

We deliver value-driven phys/chem solutions across the full project lifecycle:

Cooperative Design & Problem-Solving: We support customers in developing robust, customised solutions, evaluating unique water chemistry to design the most efficient primary treatment configuration.

Design & Build: Custom, efficient, and reliable systems built to your exact specifications.

Operations, Service, & Maintenance: Ensure continuity with comprehensive support, including full-time O&M staffing, routine service contracts, and emergency response.

De-Risking Your Project: Our Technical Edge

We ensure your investment is future-proof by employing pilot plant trials to rigorously stress-test processes and validate full-scale implementation. This allows us to establish the operational limits that guarantee performance before you break ground.

Advanced Phys/Chem Steps for Bulk Contaminant Removal

Physical-chemical treatment is often the critical first phase required to prepare a water stream for advanced biological or ion exchange processes. We select from a proven toolkit of solutions to ensure you achieve compliance reliably.

Phys/Chem Step

Process Overview & Application

Core Benefit

pH Control & Precipitation

Raising pH using caustic soda or lime softening to cause dissolved metals to precipitate.

Effectively removes the bulk of dissolved metal contamination early in the process.

Coagulation & Flocculation

Adding coagulants and polymers to enhance the precipitation and clumping of fine particles.

Increases the efficiency of downstream clarification and filtration.

Clarification & DAF

Utilizing sedimentation or Dissolved Air Flotation (DAF) to remove suspended solids.

Essential for removing high loads of BOD, COD, and suspended solids from industrial or municipal streams.

Media Filtration

Final removal of remaining particulates to protect advanced downstream systems.

Prepares the stream for targeted removal of contaminants like Selenium, Mercury, and Arsenic.

Key Capabilities:

Deaeration: Removing dissolved gases from process streams.

Integrated Systems: Combining coagulation, flocculation, and clarification for space-saving, high-efficiency treatment.

Credibility Through Performance: Results That Deliver

Our commitment to guaranteed outcomes is backed by reliable, warrantied results and deep expertise in treating the final, more difficult phases of wastewater processes.

Foundation for Advanced Treatment: By successfully managing the phys/chem phase, we enable our advanced Biological Fluidized Bed Reactors (FBR) and Ion Exchange (IX) systems to operate at peak efficiency for targeted contaminant destruction.

Broad Contaminant Reach: We have a successful track record of using phys/chem processes as part of an integrated solution for bulk organics, heavy metals, and landfill leachate.

Real-World Validation: Every system design is backed by our lab and piloting capabilities, ensuring that the specific chemical dosing and retention times are optimised for your unique water chemistry.
