ENVIPURE possesses an unsurpassed track-record in the design and supply of odor control plants and solutions for a varied range of applications and Customers :

• sewerage treatment plant
• deep tunnel sewerage network and pumping stations
• composting plant
• food-processing plant
• slaughter house
• tobacco processing plant

Offensive smell and foul malodor originating from such plants causes public nuisance and triggers complaints from affected residents. To make matter worse, long-term and enduring exposure to malodorous gases can even cause chronic illnesses.

Based on our proprietary odor scrubbing and bio-filter system, COCAS™ and BOCAS™, we design and supply chemical scrubbing and bio-filter systems for removal of H₂S, ammonia, mercaptans and other malodorous compounds up to 99.99% efficiency. Our proven technology is utilized in plant installations worldwide, stretching from the evergreen Singapore to the desert-covered Qatar.

Scope of Supply

ENVIPURE delivers INNOVATIVE and TOTAL SOLUTIONs to our Customers through :

• Design and Supply of technology package units (Tech-Pack)
• Turnkey Engineering, Procruement & Construction of odor-control plants (EPC)
• Operations and Maintenance (O&M)

The scope of technology package (Tech-Pack) includes intake-suction system, air-handling ducting system, scrubber reactor, chemical injection system, fan, emission stack, in-line measuring and monitoring system and our intelligent PLC-based control system, EiSCOS™. These critical plant components can easily be shipped to Customer's construction-site at any parts of the world, and ENVIPURE’s experienced field technicians are ready to support our Customers with erection, installation, testing and commissioning supervision services.

Track-record

With more than 30 years of experience, we have built a wide network of Customers and delivered a combined treatment capacity of more than 3,000,000 m³/h of treated odorous air. Our high market share is a strong testimonial of the confidence we have gained from our satisfied Customers, built over the years.

ENVIPURE’s proprietary scrubbers, COCAS™ and BOCAS™, have successfully eliminated odor problems generated from small localized spaces such as pumping station or head-works (5,000 m³/h), up to the capacity of centralized odor-control facilities built for large-scale sewerage treatment plants (1,000,000 m³/h).

Portfolio of Technologies

Our deep knowledge in chemistry and biology, coupled with understanding of Customers requirements, equip us with the expertise to integrate a broad range of technologies to deliver customized solutions to every unique situation. Our portfolio of process know-how and technology includes :

• cross-flow chemical scrubber (COCAS™)
• counter-flow chemical scrubber (COCAS™)
• dual-flow filters
• venturi scrubber
• bio-trickling filters (BOCAS™)
• bio-filters (BOCAS™)
• activated carbon filters

Our Proven Methodology - We Listen

Fugitive malodorous gas streams are contaminated with a variety of polluting compounds at different degrees. As such our engineers would first consult with our Customers to understand the problem and risks before engineering the most economical solution based on the best available technology.

Our Customers have come to rely on ENVIPURE not only for cost-effective and reliable odor control solutions, but also due to our strong reputation to deliver the scrubbing plants at short delivery times, guaranteed by maintaining our own state-of-art manufacturing facility in Singapore.

Our engineers take pride in providing excellent services, and today, our market reputation is built on this strong track-record.
