Technical Session
James Holland with WK Dickson
Jimmy Holland has over 25+ years in the industry with a BS in Environmental Engineering from NC State University. Jimmy is a licensed PE in both North and South Carolina and also holds a Grade 4 Operators License in North Carolina and a Level A Biological Operator in South Carolina. Jimmy will be speaking on overview of wastewater odor control chemicals and Technologies. This will include what odors are and what some of the odorous compounds experienced in wastewater. The presentation will briefly examine such technologies as Gas Adsorption Scrubbers, Dry Adsorption Scrubbers, Biological Odor Control, Fragrance, Hydroxyl Radicals, Ozone, Ionization and Photoionization.


The City of Winston-Salem has 2 waste water treatment plants, Lower Muddy Creek plant and the Archie Elledge plant. The Muddy Creek plant is permitted for 21 MGD and averages 15-17 MGD daily. The Archie Elledge plant is permitted for 30 MGD and averages 15-17 MGD.
Both WWTP send the processed sludge to 2 blending tanks located at the Archie Elledge plant, where the blended sludge from both plants are mixed using Wilo mixers in the blending tanks. The blended sludge is then pumped from the blending tanks and sent through high solids centrifuges for dewatering at the Regional Biosolids Drying Facility. At the facility we take the % TS from about 1.5% TS and dewater to around 19% TS. The dewatered cake is then pumped to the Andritz rotary drum drying system. The capacity of the system is 43 dry tons per day through put. We average around 30 dry tons per day. Our pellets % TS range from 88-92.

 

 

Two contact hours for wastewater operators will be awarded to those attendees who participate in the Technical Session and the Tour (partial credit will not be given).
