FAQs
What is trade waste?
Trade waste refers to wastewater generated from commercial or industrial activities, such as kitchens, workshops, and manufacturing processes. It typically contains higher levels of contaminants and must be treated before discharge to meet local authority requirements.
What types of wastewater can these systems handle?
Our systems are designed to treat a wide range of wastewater, including trade waste from commercial kitchens (grease arrestors), oily water from workshops and service stations (oil plate separators), and industrial effluent containing solids, grease, and hydrocarbons. The exact solution depends on the type and concentration of contaminants generated on site.
Do I need wastewater treatment for my site?
If your operations produce wastewater containing grease, oil, solids, or other contaminants, a wastewater treatment system is typically required to meet local regulations and discharge requirements. Australian water authorities and water utilities enforce trade waste regulations, and non-compliance can result in fines, system restrictions, or increased discharge costs. If in doubt, contact your local water authority to see if they have requirements for your specific project.
What’s the role of grease arrestors and oil separators?
These are essential components within wastewater management systems, removing grease and hydrocarbons before discharge to protect infrastructure and ensure compliance.
Why are grease arrestors and oil separators required?
Most municipal water authorities have strict regulations around the quality of wastewater that is accepted into their sewer systems. If site activities such as cooking a commercial kitchen are expected to produce wastewater more concentrated with contaminants, the expectation is that the concentrated wastewater is pre-treated by a treatment device (or treatment train) such as a grease arrestor prior to discharging into the wastewater network to avoid penalties and return wastewater quality back to acceptable levels.
How do sewage grinders improve system performance?
Inline sewage grinders break down solids and waste materials into smaller particles, allowing wastewater to flow more easily through pipework and pump systems. This reduces the risk of blockages, improves reliability, protects downstream assets such as pumps, and helps maintain consistent system operation.
Can these systems reduce maintenance costs?
Yes. Effective wastewater management reduces blockages, protects equipment, and lowers ongoing maintenance costs.
Are these systems suitable for retrofit projects?
Yes, many wastewater treatment solutions can be integrated into existing infrastructure and systems, including retrofitting grease arrestors, separators, or grinders into current drainage pipe layouts. These solutions assist in upgrading sites to meet new or existing compliance requirements and improve trade waste quality without major redevelopment.
How do I choose the right system for my application?
The right wastewater treatment system depends on contaminant type, required inflow and outflow and the acceptable wastewater condition required at the discharge location. A combination of equipment, such as grease arrestors, separators, pumps and inline grinders are often used to achieve the required level of treatment and compliance.
