Dewatering, seems like something that should be simple but can be incredibly complicated and, even expensive. Biosolids dewatering especially has concerns as the material is typically destined for landfill, and when sludge needs to be separated into liquid and solid forms for easy removal or storage. Using our service can make dewatering easy, affordable, even profitable. Here are a few more reasons why biosolids dewatering with Aqua-Zyme is important:
1. Disposal Costs
Landfill sites and corporate liquid disposal sites tend to carry heavy fines for disposal of liquid. By dewatering before you take waste the landfill, you can keep those costs down.
Pass the Filter Test
Biosolids dewatering can help you to pass the ‘paint filter test’ used at most landfills. According to the EPA, this test involves putting material into a paint filter and seeing if anything passes through the filter during a five minute testing period. Dewatering can help bring materials down to levels of around 18-22-percent solids.
2. Fast Dewatering
Dewatering through our company is fast. A singleplex unit can pass through 450 gallons of water per minute, and a multiplex unit can pass through even more.
3. Profit Making
Separating biosolids isn’t just an important part of waste management. You can use the process to turn a profit too. You can manage liquid waste for other companies, or re-sell the leftover sludge to the agriculture or composting industries. It can make up a nice piece of side income, make the most out of your waste materials, and help the environment all at the same time!
4. Safety
Disposing of waste material is a concern in industries where it could potentially contain harmful substances that could work their way into drinking water. Dewatering, and separating out the harmful particles means that the leftover liquid is safe to be disposed into a sewer with no risk to the environment, or to drinking water. The sludge is also treated before it is re-sold for use in agriculture or composting.
By using our dewatering systems, you can dispose of your waste liquid safely and cost effectively, pass all environmental tests, re-purpose the sludge for later use, and even turn a profit from your waste materials. Contact us today to learn more!

Unveiling the Process: How Biosolids Dewatering Works
How Biosolids Dewatering: Biosolids dewatering is a critical step in wastewater treatment processes, transforming sludge into a more manageable and environmentally friendly form. This essential process involves the removal of water from sludge, reducing its volume and creating a solid material suitable for disposal or beneficial reuse.
Mechanical Dewatering Methods: Mechanical dewatering methods are commonly used in biosolids treatment facilities to separate water from sludge. These methods employ various technologies such as centrifuges, belt presses, and filter presses to apply mechanical pressure and force water out of the sludge. Mechanical dewatering offers efficiency and scalability, making it a preferred choice for large-scale wastewater treatment plants.
Chemical Conditioning: Chemical conditioning is often employed in conjunction with mechanical dewatering methods to enhance the efficiency of the process. Chemical additives, such as polymers and coagulants, are mixed with the sludge to improve its dewaterability. These additives help to destabilize the sludge particles, allowing water to be more effectively separated during the dewatering process.
Gravity Drainage: Gravity drainage is a fundamental component of biosolids dewatering, relying on the natural force of gravity to remove water from the sludge. In this method, sludge is placed in large containers or beds where gravity facilitates the drainage of water through the sludge matrix. While gravity drainage may be slower compared to mechanical methods, it is often used in smaller-scale treatment facilities and as a preliminary dewatering step.
Thermal Drying: In some cases, thermal drying is employed to further reduce the moisture content of dewatered biosolids. Thermal drying involves subjecting the dewatered sludge to heat, either through direct contact with hot air or by using specialized drying equipment such as rotary dryers or fluidized bed dryers. This process evaporates remaining moisture, resulting in a dry and stable product suitable for disposal or beneficial reuse.
Environmental Considerations: Biosolids dewatering plays a crucial role in environmental protection and resource management. By reducing the volume of sludge and extracting water, dewatering minimizes the environmental impact of sludge disposal and transportation. Additionally, dewatered biosolids can be recycled for agricultural purposes, providing valuable nutrients to soil and promoting sustainable land application practices.
Regulatory Compliance: Compliance with regulatory standards is paramount in biosolids dewatering processes. Wastewater treatment facilities must adhere to stringent regulations governing sludge management, including guidelines for biosolids quality, handling, and disposal. By meeting regulatory requirements, facilities ensure the safe and responsible treatment of wastewater and biosolids.
In conclusion, biosolids dewatering is a fundamental step in wastewater treatment processes, facilitating the transformation of sludge into a more manageable and environmentally friendly form. Through mechanical, chemical, and thermal methods, water is effectively removed from sludge, reducing its volume and enabling beneficial reuse or safe disposal. As wastewater treatment practices continue to evolve, biosolids dewatering remains a cornerstone of sustainable and responsible resource management.
