Highly Reliable and Efficient Services for Gross Pollutant Traps and Vacuum Excavation for Industries, Businesses, and Households
Gross pollutant traps (GPT) trap solid waste such as litter and coarse sediments via physical processes. This makes it easier to remove finer sediments from wastewater in the future. These are put in place to catch stormwater pollution before it enters a waterway. At the downstream end of drains or constructed waterways that flow to rivers and urban lakes, gross pollution traps are built.
Gross pollutant trap typically consists of a sediment trap with a weir and trash rack at the downstream end. Flow enters through a concrete-lined basin and detained by the weir, improving sedimentation in the process. To manage flow and capture sediments, the system employs a network of underground chambers, screens, and weirs. The waste rack gathers debris from weir overflows. Gross pollutant traps act as a filter, trapping litter while allowing water to pass through. It can also be used to pre-treat stormwater harvesting systems. These provide a cost-effective way to reduce the contaminant loading of a site and reduce the need for system maintenance.
GPTs are primarily used to remove large and
non-biodegradable pollutants. Gross pollutant traps use physical screening,
rapid sedimentation and separation processes to trap and filter waste. It traps
litter and sediments above 5 mm in size so that these can be removed from the
waste system.
Besides trapping litter and coarse sediments, gross
pollutant traps also provide reduction in a variety of other pollutants, such
as:
- Removal
of particulate nutrients
- Removal
of oil and grease
- Removal
of trace metals
- Reduction
in bacteria
- Reduction
in dissolved oxygen demanding substances
Gross pollutant traps serving small catchments can be
installed underground. To ensure proper operation, the gross pollutant trap
must be cleaned on a regular basis. Aussie Hydro-Vac Services has a qualified
crew that understands how to service gross pollutant traps using the proper
equipment and materials. The organisation offers both one-time and planned
servicing of gross pollutant traps for cleaning and maintaining its chambers,
gross collector, bypass channel, silt chamber, garbage screen, and sections of
GPT.
Vacuum excavation to keep your
underground utilities safe
Aussie Hydro-Vac Services vacuum excavation uses
high-pressure water or air to break up soil and debris. The slurry is extracted
with the assistance of a vacuum, which is generated either by a fan system or
by a positive displacement blower. The company's vacuum excavation unit may use
a twin or triple air fan design to produce a bigger volume of air. The material
is pulled into the holding tank after passing through a micromesh filter system,
which traps dust particles.
Non-destructive and safe digging
method
Vacuum excavation is a non-destructive way of digging
that avoids damaging neighbouring structures and underground utilities. Vacuum
excavation eliminates the need for manual or abrasive excavation methods. The
soft digging approach is deemed safe since it protects employees from trench
cave-ins. When working in frozen ground, hydro excavation is useful since hot
water can be used to defrost and break the soil. Vacuum excavation is a
low-impact, non-destructive digging method that is gaining favour in Australia
due to its high efficiency and cost-effective operations. Aussie Hydro-Vac
Services can supply you with the best vacuum excavation solution for your
project's needs.
Key applications of vacuum
excavation
- Can be used to perform deep excavation for large depths, like cleaning storage tanks. Deep excavation provided by vacuum excavation is best suited to perform renovation or restoration of a building or structural foundation.
- Underground utilities, cables, and pipes can be exposed without causing any damage to them. This way, vacuum excavation ensures that these utilities are not damaged, and your facilities remain functional while the process is underway.
- Vacuum excavation is also best suited for the soil improvement techniques requiring the removal of contaminated soil and gravel, or solid spills. Vacuum excavation is also used to improve the soil around trees and eliminate roots that create a mess around the buried utilities, like pipes and cables.
