PROJECTS

Project scope

Mixed NF, RO and DTRO membrane concentrate from landfill leachate, 300 tonnes per day.

UV role

UV based advanced treatment was integrated after upstream conditioning to support further polishing of high strength concentrate streams.

Key outcomes

• COD ≤ 50 mg L^-1
• BOD₅ ≤ 10 mg L^-1
• NH₃ N ≤ 5 mg L^-1
• TN ≤ 30 mg L^-1

PFAS relevance

Landfill leachate membrane concentrate is a key residual stream where PFAS may accumulate. This project demonstrates HEMA's capability in concentrate management, UV integrated treatment and complex matrix control.

Project scope

Semiconductor industrial wastewater, 45,000 tonnes per day.

Treatment role

Integrated treatment was applied to manage low organic concentration wastewater and fluoride related contaminants under strict industrial operating conditions.

Key outcomes

• Treatment capacity 45,000 tonnes per day
• Fluoride related contaminant control
• Stable operation in an advanced manufacturing wastewater system

PFAS relevance

Semiconductor wastewater is relevant to future PFAS applications because advanced manufacturing may involve fluorinated chemicals and strict discharge requirements. This project demonstrates HEMA's capability in fluorine related wastewater management, process integration and reliable industrial operation.

Project scope

Food waste digestate membrane concentrate, 180 tonnes per day.

UV role

UV based advanced treatment was integrated after upstream conditioning to support polishing of high strength organic concentrate streams.

Key outcomes

• COD ≤ 5 mg L^-1
• BOD₅ ≤ 10 mg L^-1
• NH₃ N ≤ 0.5 mg L^-1
• TN ≤ 5 mg L^-1

PFAS relevance

Food waste membrane concentrate represents a complex organic residual stream where persistent contaminants may coexist with high COD, salts and variable matrices. This project demonstrates HEMA's capability in organic concentrate treatment, UV integrated polishing and stable operation.

Project scope

Battery production wastewater, 10 tonnes per day, with associated domestic and cooling water streams of 210 tonnes per day.

UV role

UVlogic was integrated with EMlogic to support advanced treatment of high strength battery production wastewater.

Key outcomes

• Influent COD > 2000 mg L^-1
• Final water quality met discharge and reuse requirements
• Reuse oriented water quality control for cooling water applications

PFAS relevance

Battery wastewater is relevant to future PFAS treatment in advanced manufacturing because it involves complex chemistry and strict water quality control. This project demonstrates HEMA's capability in UV integrated treatment, process integration and reuse oriented system design.
