What Is Zero Liquid Discharge and How Does It Work?

Not every industrial facility that produces wastewater will require zero liquid discharge (ZLD). It is usually looked to as a last resort because it can be a complex process that requires a high initial investment.

If a facility is located on a site that has severe water scarcity issues and/or astronomical discharge fees, it might be worthwhile to pursue, but in the instances it's not mandated (some local and/or federal regulations might require ZLD), careful consideration must be made as to whether or not it will benefit your facility.

If your facility does require or is considering it, you might be wondering, "what is zero liquid discharge and how does it work?"

The complex answer to this question is simplified and broken down for you below:

What is a zero liquid discharge treatment system?

A ZLD treatment system utilizes advanced technological water treatment processes to limit liquid waste at the end of your industrial process to, as the name suggests, zero.

An efficient and well-designed ZLD treatment system should be able to:

handle variations in waste contamination and flow

allow for required chemical volumes adjustments

recover around 95% of your liquid waste for reuse

treat and retrieve valuable byproducts from your waste (i.e. salts and brines)

produce a dry, solid cake for disposal

A ZLD treatment system will also help your facility meet stringent effluent requirements, such as the U.S. Environmental Protection Agency's Steam Electric Power Generating Effluent Guidelines. Just keep in mind your facility's requirements will vary based on whether you are discharging into a publicly owned treatment works (POTW) or to the environment under a National Pollutant Discharge Elimination System (NPDES permit).

What's included in a basic ZLD treatment system?

The exact components of a ZLD treatment system will largely depend on (1.) the volume of dissolved material present in the waste, (2.) the system's required flow rate, and (3.) what specific contaminants are present. But in general, a basic ZLD treatment system typically includes some type of:

clarifier and/or reactor to precipitate out metals, hardness, and silica

chemical feed to help facilitate the precipitation, flocculation, or coagulation of any metals and suspended solids

filter press to concentrate secondary solid waste after pretreatment or alongside an evaporator

ultrafiltration (UF) to remove all the leftover trace amounts of suspended solids and prevent fouling, scaling, and/or corrosion down the line of treatment

reverse osmosis (RO) to remove the bulk of dissolved solids from the water stream in the primary phases of concentration

brine concentrators to further concentrate the reject RO stream or reject from electrodialysis to further reduce waste volume

evaporator for vaporizing access water in the final phases of waste concentration before crystallizing.

crystallizer to boil off any remaining liquid, leaving you with a dry, solid cake for disposal

Depending on the needs of your plant and process, these standard components are usually adequate, however, if your plant requires a system that provides a bit more customization, there might be some features or technologies you will need to add on. Because of the broad range of industries that use ZLD and the various waste streams produced, ZLD is a highly custom process and these add ons will depend on your facility's individual needs.
