Dewatering is a process used to remove water from the liquid and solid combination of waste material. Through the use of this specialized equipment, wastewater with solids enters into the tank or unit, and the solids are removed, allowing water to be let out of the tank and into the sewer system.
To do this effectively, the dewatering equipment has to have a processing capacity required as well as the ability to remove the required solids to allow for disposal of the water in the sewer system. In some cases, particularly in rural areas, the water may be diverted elsewhere, but it has to be free from solid materials and contaminants as per local ordinances and regulations.
Capacity
There are different options in dewatering equipment. The most common is a roll-off dewatering unit, which allows for easy movement of the unit once it reaches the maximum level of solids in the tank. The tanks are purchased, then the business can contract for dumping or invest in their own truck.
To ensure maximum capacity in plants and facilities with large volume dewatering needs, consider the tank size and the processing rate. Some companies offer a multiplex system which can dramatically increase the processing rate. Typically, with a quality provider, even a singleplex system will be able to process up to 450 gallons of water per minute.
By choosing a dewatering system which is in excess of what your business will use, you can turn the residual capacity into potential incomes. A business can charge surrounding companies for the use of the dewatering equipment which helps to offset the cost.
In many areas, the dewatered sludge can also generate income, depending on the specific solids present. There may also be composting sites which can accept the waste, and some waste may be suitable for direct sale to agribusiness and similar industries.
