Screening system saves company time and money

Screening system saves company time and money

Problem: Aqua Engineers has been serving the Hawaiian Islands in both the water and wastewater industry for 37 years. With the limited amount of space at the sites the Oahu Wastewater System team services, building a drying bed was not feasible. This meant the company’s team driving about an hour away to the available drying bed and having to return to clear out the bed after the debris dried.

Solution: The Mega Screen from ScreenCo Systems allows the company to dewater and clean onsite at one of its pump stations. 

Result: The Mega Screen has saved time and increased productivity of the team, as it provides a quick and easy way to unload their Vactor vacuum truck. 208-790-8770;

Screening system helps plant solve FOG issues

Problem: A regional treatment plant in Pennsylvania has had a truck waste-receiving program for many years. However, the percentage of FOG being discharged had grown significantly. The plant decided to establish a separate FOG receiving station and needed an efficient screen.

Solution: The plant set up a controlled pilot test. Objectives included demonstrating the screen’s ability to accept gravity or pressurized flow from various size trucks, quantifying the amount of debris captured, demonstrating that the screen did not need a rock trap or grinder, and verifying truck unloading times. They chose the Enviro-Care Beast septage, FOG and sludge screening system after the unit screened an average of 20 trucks per day for one month. The loads ranged from coagulated grease the consistency of oatmeal to grease similar to SAE 30 oil. Even the mixed-load trucks with large quantities of rags and rocks were not a problem, and the unit didn’t require a rock trap or grinder.

Result: Feedback from the haulers and plant personnel was positive, as well as the data collected on the four objectives. Plant personnel terminated the balance of the pilot test and purchased two FOG Beast 1400 screening systems. 815-636-8306;

Septage plant helps pump station achieve biosolids quality goal

Problem: In Newark, Ohio, a pump station was struggling to cope with rags and hair. Despite having a grinder, debris such as plastics were getting into the digesters and adversely affecting the quality of biosolids at the plant, which treats around 2.75 million gallons per year of septic waste.

Solution: A self-contained, fully automatic Raptor Septage Acceptance Plant from Lakeside Equipment was installed. Designed with a heavy-duty three-plane fine screen, it employs a rotating rake that passes through the full depth of the basket bars to remove debris from the screening area. The rotating rake deposits collected screenings into a central screw conveyor hopper that leads to a transport tube. Screenings are spray-washed in two stages to return organic materials to the liquid stream.  

Result: The unit’s smaller footprint made it easier to use and more economical, according to Darin Wise, Newark plant superintendent. “I fully expect our unit to give us a good 20-years-plus of dependable duty,” he reports. 630-837-5640;
