POND DREDGING & SLUDGE REMOVAL.
We perform pond dredging using our high-capacity dredges to complete sludge removal from wastewater treatment ponds.
When undertaking pond dredging, we have the capability of pumping the sludge up to 1 kilometre, meaning our equipment is suitable for sludge removal from all sizes of wastewater treatment pond.
Multiple options are available for dewatering the sludge on-site during the pond dredging process, including fully contained systems that allow the dewatered sludge to be immediately transported off site, or stationary geotubes that accommodate high volumes of sludge.
BENEFITS.
SLUDGE SURVEYS.
Sludge surveys are the recognised way of establishing volumes, depth, density and spread of sludge within a pond.
Once we have gathered the readings and data on site, we will provide you with a comprehensive and detailed report that will allow you to make informed decisions on sludge removal and budgeting for your pond maintenance.
We can also provide you with laboratory analysis of the sludge, which will identify and contamination concerns, and allow us to provide you with appropriate treatment options.
NITROGEN REMOVAL.
Treated wastewater typically undergoes a nitrification and denitrification process as part of its treatment at wastewater treatment plants to remove ammonia nitrogen and ammonium from the wastewater effluent.
However, during times of seasonal peak loads this treatment process can cannot always sufficiently slowed to allow the time required for the successful removal of nitrogen from water, resulting in the treated effluent potentially exceeding its allowed nitrogen limit.
We have treatments available for nitrogen removal from effluent and achieving discharge consent compliance in these situations.
WAS COLLECTION.
Our ability to dewater on-site greatly reduces the cartage involved in removing Waste Activated Sludge (WAS) from satellite MBR & SBR plants. The high volume we can process in one visit allows these plants sludge levels to be maintained for optimum operating performance of the plant.
SEPTIC TANK CLEANING.
Our ability to remove all contents of the septic tank, then return the filtered water means the bacteria that promote healthy waste digestion are retained for the ongoing effective operation of the septic tank.
DAF REMOVAL.
In situations where Dissolved Air Floatation (DAF) has a significant liquid content, we can provide routine dewatering, collection, and cartage services that allow for the efficient removal of the remaining sludge.
DIGESTER CLEANING.
Wastewater treatment plants play a critical role in effectively treating the waste created by the community it serves.
The heart of these facilities often lies in the anaerobic digester, a vital component responsible for breaking down organic matter and converting it into biogas and biosolids.
Over time, inorganic materials, organic solid residues, and debris can build up in your digester, leading to decreased efficiency and reduced capacity and efficiency.
Our digester cleaning techniques involve the removal of these accumulated deposits and debris by using vacuum extraction. Dewatering of the extracted solids and liquid and removal from site can also be performed.
Our skilled technicians have the expertise to perform the required Confined Space Entry and thoroughly clean your digester, removing any solids that might hinder the digestion process and your facility’s performance.
We understand that each wastewater treatment facility is unique, and their digester cleaning requirements may vary. That’s why we provide tailored solutions to address your specific needs. Our team will assess your digester’s condition and develop a customized cleaning plan that maximizes results while minimizing disruption to your operations.
