Grade, Specification & Capacity of Wastewater Evaporators

grade and specs of new wastewater evaporatorsWaste Water Evaporators are usually constructed with different features in mind to full certain needs and applications with the desired capacity. Usually depending on its uses on which type of industry, the selection of material for construction of the whole unit can either be complete stainless steel or carbon steel. Typically, if let’s say the incoming influent wastewater is non-corrosive in nature such as those coming from cleaning solution, steam condensate and compressors, selection of carbon steel version is more than good enough. Vice versa if the generated wastewater is from die cast solution especially from metal plating industry, then it would be best if the body and tanks are constructed using stainless steel grade.

Waste Water Evaporators are also categorized and graded according to its designed capacity. A normal small-sized unit can be made with the capacity ranging between 2 to 5 gallons per hour and the holding evaporation tank capable taking in at least 50 – 100 gallons at any one time. Apart from that, usually engineers also prefer having a setup that can handle a one time loading and overall it requires very less attention and minimum supervision in order to run the evaporator unit. Usually a well-designed waste water evaporator should be equipped with high and low level sensors so that influent feed can be controlled in order to avoid overflow, carryover to the condenser system or as in the case of dry up of incoming feed, this is to prevent damage to the pump running dry.

"Evaporation rate" is a very important specification when looking for the right unit to fulfill your needs and demands. Most often, people would make a simple mistake getting an undersized evaporator and learning later part that it is not enough to fulfill the requirements and increased volume later part due to plant expansions. For a waste water evaporator to function optimally, it should be equipped not only with an easy-to-manage tray system to remove residual solid waste collected at the bottom but also the whole setup must be constructed for easy maintenance especially cleaning to remove buildup of entrained materials. These days, some evaporators are sized up to take in waste water as much as 10 gallons per hour and while this presents a challenge to the operators to constantly monitor its run and performance, nevertheless they are still considered more cost effective than running a large scale treatment plant.

Finally, other than what is mentioned above, a quality grade of waste water evaporators should also have the necessary utilities to increase efficiency and performance such as installation of vacuum pumps, high pressure feed pumps and built-in skimmer in order to take out low density non-soluble waste. In fact, a highly effective portable unit should also come with proper coupling and also complete socket that offers fast setup up in just a matter of hours.
