What HOH Corp does

HOH Corporation is a privately held, founder-owned industrial wastewater treatment company headquartered in Winston-Salem, North Carolina, founded in May 1993 by David Bryant (President) and Paul Pelton (Vice President). The firm operates two primary divisions plus a parts distribution arm: a Wastewater Treatment Division running a 22,000 sq. ft. CWT-permitted facility for non-hazardous streams (oil/water separation, physical-chemical treatment, ultra-filtration, nano-filtration, carbon columns, rotary vacuum, solidification), and a Manufacturing/Equipment Division that designs and builds oil/water separators, floating oil skimmers, soil vapor extraction systems, and package treatment plants. A Carolina Pumps & Instrumentation (CPI) Division supplies aftermarket pumps, valves, tanks, filtration, and instrumentation.

Core proprietary technology centers on THE CUBE® — patented perforated coalescing media with oleophilic geometry that delivers 90 ft.² per ft.³ of separation area and removes oil droplets down to 2 microns — and the SKIMSTER® family of floating weir skimmers. These are integrated into the SKIMSTER® OWS mobile spill-response trailer, which combines CUBE media with MYCELX hydrocarbon polishing filtration to achieve less than 15PPM oil-in-water effluent. The company holds a US EPA Centralized Waste Treatment (CWT) Permit under Subcategory D (issued July 2002, among the first in the U.S.), authorizing treatment of metal-bearing, oily, and organic wastewater.

HOH generates revenue across four streams: (1) usage-based treatment fees at its CWT facility for non-hazardous industrial wastewater; (2) capital equipment sales of separators, skimmers, SVE systems, and package plants to industrial, utility, and government customers; (3) transaction-based product destruction fees using a RETECH rotary grinder at up to 2,200 lbs./hr; and (4) one-time replacement parts and consumable equipment sales via the CPI division. GTM is sales-led and direct — phone (336.727.4644) and an online Quick Response Form — with domestic buyers (industrials, utilities, municipalities, government, environmental consultants, marina operators) served directly and international markets handled exclusively through Green Global Technology. Pricing is quote-based across all streams; no public pricing, funded capital, or revenue figures are disclosed.
