Title: Lloyd J Parcell: Innovator in Environmental Engineering
Introduction
Lloyd J Parcell is a notable inventor based in Beaumont, TX (US), recognized for his contributions to environmental engineering. He holds a total of 3 patents that focus on innovative methods for treating biosludge and wastewater.
Latest Patents
One of his latest patents is the "High Rate Sludge Reactor." This invention is designed for the treatment of biosludge and combines processes such as landfarming, sand bed dewatering, and forced aeration composting. The reactor consists of a sand bed over a drainage system housed in an inflatable, pressurized building. It effectively treats biosludge through dewatering and biodegradation, achieving volume reduction, stabilization, and solidification at improved rates compared to conventional practices. The reactor operates independently of climate conditions and minimizes environmental monitoring due to its closed system design.
Another significant patent is the "Rotating Disk Biotreatment of Syngas Waste Water." This method upgrades wastewater containing harmful substances like formates, cyanides, and ammonia. It utilizes aerobic bacteria immobilized on the disks of a rotating disk contactor to biodegrade formates and cyanides, while ammonia is removed through air stripping. This innovative approach eliminates the need for steam stripping and lime addition stages found in conventional processes.
