Expert answers on wastewater treatment systems, products, and services

Baldwin Industrial Systems has provided industrial wastewater treatment solutions for more than 35 years. This page compiles the most common questions about our systems, technologies, and services, from installation and performance to maintenance and compliance.

Whether you’re researching a specific unit, comparing technologies, or planning a new treatment installation, you’ll find answers here.

General Questions About Wastewater Treatment

What is industrial wastewater treatment?

Industrial wastewater treatment is the process of removing contaminants from manufacturing or processing water so it can be safely discharged or reused. Baldwin designs and builds complete wastewater treatment systems for industries such as mining, manufacturing, food processing, and petroleum refining.

Why is wastewater treatment important for Australian businesses?

Untreated wastewater can pollute waterways and breach EPA discharge regulations. Baldwin’s systems ensure compliance with Australian environmental standards while improving operational efficiency and reducing waste management costs.

What types of wastewater systems does Baldwin design and manufacture?

Baldwin produces complete end-to-end wastewater systems, including:

  • Coalescing plate separators  
  • RM-10/OSU systems for specialty chemical treatment 
  • pH control and chemical dosing systems
  • Filtration and polishing media
  • Floating and tube oil skimmers
  • Clarifiers, pumps, and control panels
  • DAF systems for solids and oil removal 

Each system is available as a standalone unit or integrated into a complete modular wastewater treatment solution.

Product-Specific Questions

What is a DAF system and how does it work?

A Dissolved Air Flotation (DAF) system removes suspended solids and oils by using fine air bubbles to lift contaminants to the surface for removal. Baldwin DAF systems improve water clarity and reduce downstream maintenance across industrial and commercial applications.

When should I use a coalescing plate separator?

Coalescing plate separators are ideal for removing free oils and hydrocarbons from wastewater. They are commonly used in service stations, mechanical workshops, and industrial sites. Baldwin’s plate packs are modular, easy to clean, and designed for continuous operation.

What does the RM-10/OSU system do?

The RM-10/OSU provides one-step chemical treatment for difficult wastewater. It removes emulsified oils, heavy metals, and suspended solids using a bentonite clay–based chemical process. It’s proven across workshop wash bay, paint, and compressor station wash applications.

What is the purpose of pH control and chemical dosing in wastewater treatment?

pH control systems balance acidity and alkalinity to ensure wastewater meets discharge requirements. Baldwin dosing systems automatically inject precise quantities of neutralising agents, such as acids, alkalis, or flocculants, based on site-specific flow conditions.

How do oil skimmers and decanters differ?

Oil skimmers remove floating oils and contaminants from water surfaces, while decanters separate solids and liquids for further treatment. Baldwin’s Skim-Pak range offers both fixed and floating configurations for ponds, refineries, and food processing facilities.

What are the benefits of using filtration and polishing media?

Filtration and polishing media remove fine solids, hydrocarbons, and trace contaminants following primary treatment. Baldwin units combine coarse and fine filtration for optimal results, reducing downstream blockages and ensuring compliance with trade waste limits.

What types of pumps are used in wastewater treatment systems?

Baldwin supplies air diaphragm, progressive cavity, and centrifugal pumps designed for continuous-duty wastewater applications. Each type supports different flow rates and fluid viscosities, ensuring consistent performance across chemical, oily, and particulate waste streams.

Technologies & Innovation

What wastewater treatment technologies does Baldwin use?

Baldwin continually develops new treatment technologies for industrial wastewater management, including:

  • Aeration
  • Sludge fixation and de-watering systems
  • Industrial wastewater recycling systems
  • Powder feeder technology for chemical dosing and neutralisation

All products are engineered and manufactured in Australia with the latest process technology and control systems.

Services & Support

What services does Baldwin offer alongside equipment supply?

Baldwin provides complete project support, including:

  • Site assessments and performance prediction
  • Equipment installation and commissioning
  • Operator training and system maintenance
  • Pilot plant trials and FAT testing

How does a site assessment work?

Baldwin engineers visit your site to evaluate wastewater characteristics and flow requirements, then provide a tailored proposal with recommended treatment solutions and projected compliance outcomes.

What is a pilot plant, and when is it used?

A pilot plant is a small-scale test unit that verifies treatment efficiency before full system installation. Baldwin’s pilot plants confirm design performance, chemical compatibility, and regulatory compliance for large-scale operations.

Does Baldwin provide system maintenance and servicing?

Yes. Baldwin’s authorised distributor network provides nationwide maintenance and upgrade services for both Baldwin systems and compatible third-party equipment.

Compliance & Training

Are Baldwin systems compliant with Australian standards?

All Baldwin systems are designed and built in accordance with Australian environmental and safety regulations. Each installation is tested to ensure it meets site-specific discharge requirements.

Is operator training provided?

Yes. Every full installation includes operator training to ensure on-site teams can safely operate and maintain the equipment.
